Mac Addr |
MAC address of station being sought (destination MAC address of canureach_ex packet). |
NetBIOS Name |
NetBIOS name of station being sought (destination MAC address of NQ_ex packet). |
status |
Result of station search. The status can be one of the following: •FOUND—Station has recently sent a broadcast or responded to a broadcast. •SEARCHING—Router has sent a broadcast to this station and is waiting for a response. •NOT_FOUND—Negative caching is on, and the station has not responded to queries. •UNCONFIRMED—Station is configured, but DLSw has not verified it. •VERIFY—Cache information is being verified because cache is going stale, or the user configuration is being verified. |
Loc. |
Location of station. LOCAL indicates that the station is on the local network. REMOTE indicates that the station is on the remote network. |
peer/port |
Peer/port number. If the Loc. field lists a REMOTE station, the peer/port field indicates the peer through which the remote station is reachable. If the Loc. field lists a LOCAL station, the peer/port field indicates the port through which the local station is reachable. For ports, the port number and slot number are given. Pxxx-Syyy denotes port xxx slot yyy. If the station is reachable through a bridge group, that is shown by TBridge-xxx. |

Table 34 describes the specified fields shown in the displays.
Table 34 show extended channel csna Field Descriptions
|
|
|
Path |
Path from the CSNA configuration. |
Dev |
Device address from the CSNA configuration. |
Status |
State of the CSNA device. One of the following values: •closed—Subchannel is closed. •pendingOpen—An Open Subchannel command has been received from virtual telecommunications access method (VTAM). •open—Subchannel is open. •pendingSetup—VTAM has queried Channel Interface Processor (CIP) for all configured MAC adapters. •setupComplete—All internal MAC adapter information has been collected from the CIP. The CSNA subchannel is operational. •pendingClose—A Close Subchannel command has been received from VTAM. •unknown—Current state of the CSNA subchannel cannot be determined. |
SlowDown |
Status of flow control for the CSNA device. •off—Subchannel is normal (both CSNA and VTAM are able to send data. •sent— CSNA has put VTAM into a slow down state for this CSNA subchannel. •received—VTAM has put the CSNA subchannel into a slow down state. •both—Both VTAM and the CSNA subchannel are in a slow down state. •unknown—Current state of flow control on this CSNA subchannel cannot be determined. |
maxpiu |
Maximum size of a channel I/O block that the CSNA subchannel can send to the host. This value may differ from the configured maxpiu value if the value is reconfigured while the CSNA subchannel is active (setupComplete). CSNA blocks Systems Network Architecture (SNA) frames into channel I/O blocks which must not exceed the maxpiu value. A length-delay value less than the maxpiu value can cause the channel I/O blocks to be limited to the lower value. The maxpiu value may be reconfigured while the subchannel is operational but the new maxpiu value does not take effect until the subchannel is reinitialized (in other words, until the XCA major node is recycled). In this case, the maxpiu value displayed with the admin keyword will be the new, configured value while the maxpiu displayed by the oper keyword will be the old, operational value. |
time-delay |
CSNA blocks SNA frames destined for VTAM for time-delay milliseconds from the time the first SNA frame within a channel I/O block is blocked from sending. This can increase the overall throughput of CSNA by minimizing the number of channel I/O operations. However, blocking can induce response time latency of a transaction by up to the time-delay value. If time-delay=0, CSNA ignores length-delay and puts each frame into the channel I/O block for sending to the host. Even with a time-delay=0, CSNA may still block frames while waiting for a previous channel I/O to complete. |
length-delay |
CSNA blocks SNA frames destined for VTAM when the current block reaches the length-delay value in size (bytes). This will increase the chance of using larger block sizes for CSNA channel I/O. SNA frames are blocked up to either time-delay milliseconds or until the block reaches the length-delay size, at which time CSNA starts the channel I/O. The length-delay is ignored if larger than the maxpiu value. It can be used to force CSNA blocking to generate smaller I/O blocks than specified by maxpiu. In general, however, larger blocks result in better channel throughput and efficiency. A value of zero causes the length-delay value to be ignored; blocking is then controlled by the maxpiu and time-delay parameters. |
Blocks Transmitted |
Number of channel I/O blocks sent to VTAM from this CSNA subchannel. The Blocks Transmitted value may be higher than the total blocks for the Txd by maxpiu, Txd by time-delay, and Txd by length-delay counters. This is due to NULL blocks (8 bytes each with no data) that CSNA sends. The channel program used for link-state advertisement (LSA) traffic consists of a write/read CCW chain. When VTAM has data for CSNA it sends it with the write CCW. When the chained read CCW is executed CSNA will respond with any pending inbound data. If CSNA has no pending inbound data the read CCW is satisfied with an 8-byte header indicating no data. |
Blocks Received |
Number of channel I/O blocks received from VTAM by this CSNA subchannel. |
Slow downs Sent |
Number of times CSNA put VTAM into a slowdown (flow control) for this subchannel device. |
Slow downs Received |
Number of times VTAM put CSNA into a slowdown (flow control) for this subchannel. |
Txd by maxpiu Blocks/Bytes |
Number of channel I/O blocks and bytes sent to VTAM by this CSNA subchannel because the size of the channel I/O block reached the maxpiu value configured for this subchannel. |
Txd by time-delay Blocks/Bytes |
Number of channel I/O blocks and bytes sent to VTAM by this CSNA subchannel because the blocking time delay configured for this subchannel expired. |
Txd by length-delay Blocks/Bytes |
Number of channel I/O blocks and bytes sent to VTAM by this CSNA subchannel because the blocking length delay configured for this subchannel was reached. |

Table 36 describes the specified fields shown in the display.
Table 36 show extended channel ip-stack Field Descriptions
|
|
|
Alias addresses |
Virtual IP addresses assigned to the real IP address of an offload device. |
Forwarding |
Indication of whether this entity is acting as an IP gateway in respect to the forwarding of datagrams received by, but not addressed to, this entity. IP gateways forward datagrams. IP hosts do not (except those source-routed via the host). Note that for some managed nodes this object may take on only a subset of the values possible. Accordingly, it is appropriate for an agent to return a "badValue" response if a management station attempts to change this object to an inappropriate value. |
DefaultTTL |
The default value inserted into the Time-To-Live field of the IP header of datagrams originated at this entity whenever a TTL value is not supplied by the transport layer protocol. |
InReceives |
Total number of input datagrams received from interfaces, including those received in error, for this IP address instance. |
InHdrErrors |
Number of input datagrams discarded due to errors in their IP headers, including bad checksums, version number mismatch, other format errors, time-to-live exceeded, errors discovered in processing their IP options, and so on. |
InAddrErrors |
Number of input datagrams discarded because the IP address in their IP header's destination field was not a valid address to be received at this entity. This count includes invalid addresses (for example, 0.0.0.0) and addresses of unsupported classes (for example, Class E). For entities that are not IP gateways and therefore do not forward datagrams, this counter includes datagrams discarded because the destination address was not a local address. |
ForwDatagrams |
Number of input datagrams for which this entity was not their final IP destination, as a result of which an attempt was made to find a route to forward them to that final destination. In entities that do not act as IP Gateways, this counter will include only those packets that were source-routed through this entity, and the source-route option processing was successful. |
InUnknownProtos |
Number of locally-addressed datagrams received but discarded because of an unknown or unsupported protocol. |
InDiscards |
Number of input IP datagrams for which no problems were encountered to prevent their continued processing, but that were discarded (for example, for lack of buffer space). Note that this counter does not include any datagrams discarded while awaiting reassembly. |
InDelivers |
Total number of input datagrams delivered to IP user protocols (including Internet Control Message Protocol (ICMP)). |
OutRequests |
Total number of IP datagrams that local IP user-protocols (including ICMP) supplied to IP in requests for sending. Note that this counter does not include any datagrams counted in ipForwDatagrams. |
OutDiscards |
Number of output IP datagrams for which no problem was encountered to prevent sending them to their destination, but that were discarded (for example, for lack of buffer space). Note that this counter would include datagrams counted in ipForwDatagrams if any such packets met this (discretionary) discard criterion. |
OutNoRoutes |
Number of IP datagrams discarded because no route could be found to send them to their destination. Note that this counter includes any packets counted in ipForwDatagrams that meet this no-route criterion. Note that this includes any datagrams that a host cannot route because all of its default gateways are down. |
ReasmTimeout |
Maximum number of seconds that received fragments are held while they are awaiting reassembly at this entity. |
ReasmReqds |
Number of IP fragments received that needed to be reassembled at this entity. |
ReasmOKs |
Number of IP datagrams reassembled. |
ReasmFails |
Number of failures detected by the IP reassembly algorithm (for whatever reason: timed out, errors, and so on). Note that this is not necessarily a count of discarded IP fragments because some algorithms (notably the algorithm in RFC 815) can lose track of the number of fragments by combining them as they are received. |
FragOKs |
Number of IP datagrams that have been fragmented at this entity. |
FragFails |
Number of IP datagrams that have been discarded because they needed to be fragmented at this entity but could not be, for example, because their Don't Fragment flag was set. |
FragCreates |
Number of IP datagram fragments that have been generated as a result of fragmentation at this entity. |
RoutingDiscards |
Number of routing entries that were chosen to be discarded even though they are valid. One possible reason for discarding such an entry could be to free buffer space for other routing entries. |

|
|
t1-time |
Length of time in milliseconds the CMCC LLC2 link station waits for an acknowledgment to a sent I-frame before polling the remote LLC2 station. |
tpf-time |
Length of time in milliseconds the CMCC LLC2 link station waits for a final response to a poll before resending the original poll frame. |
trej-time |
Length of time in milliseconds the CMCC LLC2 link station waits for a correct frame after sending a reject command to a remote LLC2 station. |
tbusy-time |
Length of time in milliseconds the CMCC LLC2 link station waits before repolling a busy LLC2 station. |
idle-time |
Frequency of polls during periods of idle traffic. |
local-win |
Maximum number of I-frames that the CMCC LLC2 link station connection can send to the remote LLC2 station without receiving an acknowledgment. |
recv-wind |
Maximum number of I-frames that the CMCC LLC2 link station connection can receive without receiving an acknowledgment. |
N2 |
Number of times the CMCC LLC2 link station connection will resend an unacknowledged I-frame. |
N1 |
Maximum size of LLC frames supported by the CMCC LLC2 link station. The maximum size LLC frame supported on the CMCC is controlled by other factors including the largest interface MTU between the CMCC and the remote network device, and configured values at virtual telecommunications access method (VTAM) and at the end station. |
ack-delay |
Maximum amount of time the CMCC LLC2 link station allows received I-frames to remain unacknowledged. The CMCC LLC2 connection will acknowledge received I-frames within the ack-delay time. |
ack-max |
Maximum number of I-frames the Channel Interface Processor (CIP) LLC2 link station receives before sending an acknowledgment. |
Nw |
Working send window size. When I-frames sent by the CMCC are rejected by the remote LLC2 station, the CMCC LLC2 connection reduces its working send window size to 1. Then, for every subsequent I-frame sent by the CMCC LLC2 connection that is positively acknowledged by the remote LLC2 station, the CMCC LLC2 connection increases its working send window by the Nw value until the working send window reaches the configured local-window value. |

Table 46 describes the specified fields shown in the display.
Table 46 show extended channel statistics Field Descriptions
|
|
|
Path |
Path from the CLAW, offload, CMPC, CMPC+, or CSNA configuration. |
Dev |
Address for each device. For CLAW and offload, there are two device addresses. In the configuration statement, you specify only the even numbered address. Both CSNA, CMPC, and CMPC+ have one device. |
Connects |
Number of times the channel started a channel program on the device. |
Command Retries |
Number of times the CMCC adapter either had no data to send to the channel (for the read subchannel) or the number of times the CMCC adapter had no buffers to hold data from the channel (for the write subchannel). Every command retry that is resumed results in a connect. A command retry can be ended via a cancel. |
Cancels |
Host requested any outstanding operation to be terminated. It is a measure of the number of times the host program was started. |
Selective Reset |
Resets only one device. On the virtual machine (VM), selective reset occurs when a device is attached and a CP Initial Program Load (IPL) command is issued. |
System Reset |
Number of times the system IPL command was issued. A system reset affects all devices on the given channel. The command is always issued when the ESCON Channel Adapter (ECA) is initialized, and when the channel is taken off line. |
Device Errors |
Errors detected by the ESCON or parallel interface because of problems on the link. This value should always be 0. |
CU Busy |
Number of times the adapter returned a control unit busy indication to the host. This indication occurs after a cancel or reset if the host requests an operation before the CMCC adapter has finished processing the cancel or reset. |
Dev-Lnk |
First number is the device address. The second number is the logical link. Link 0 is always used for CLAW control messages. For IP datagram mode, link 1 is for actual datagram traffic. For offload, link 2 is for application program interface (API) traffic. For CSNA, CMPC, and CMPC+, the Dev-Lnk is not relevant. |
Blocks Read/Write |
Count of channel blocks that are read and written from the mainframe. |
Bytes Read/Write |
Sum of the bytes in the blocks. |
Dropped Blk Read/Write |
If the Route Processor sends data to the CMCC adapter faster than it can send it to the channel, then the block is dropped. High values mean the host is not running fast enough. A write drop occurs if the CMCC adapter fails to get a router processor buffer x times for a given block. See the Memd wait counter. |
Memd wait |
Number of times the CMCC adapter could not obtain a buffer. |
Con |
For link 0, a connection of Y means the system validation is complete. For all other links, Con means the connection request sequence is completed. For CSNA devices, a value of Y is displayed when the CSNA device status is complete. For all other states, the Con shows a value of N. Note If you halt the host or terminate virtual telecommunications access method (VTAM) using the Z NET, CANCEL command, VTAM does not halt the subchannels, and CON shows a value of Y until the subchannels time out (approximately 180 seconds).

|
Channel1/0: state |
State can be up, down, or administratively down. |
Flags |
•GO-OFF—CMCC adapter is trying to shut down the channel interface. This state should not persist for more than a few seconds. This flag is not applicable to the virtual channel interface. •INVALID—All displays for virtual channel interfaces should contain this flag. On physical channel interfaces, it indicates a problem with the CMCC adapter microcode. •LOADED—Channel firmware for the physical channel interface is loaded. The channel firmware is loaded only if the interface configuration contains at least one device configuration statement and is not shut down. This flag matches the state of the "loaded" LED. This flag is not applicable to the virtual channel interface. •LOVE—Note indicating an interface state change (up-down or down-up) is pending on this interface. This state should not persist for more than a few seconds. •OFFLINE—For an ESCON channel interface, this flag indicates that no mainframe has established an ESCON logical path corresponding to the paths specified in any device configuration statement (claw, offload, csna, or cmpc). For a parallel channel interface, this flag indicates that the x'0100' path is not defined in any device configuration statement or SIGNAL is not present. |
Flags (continued) |
•ONLINE—For an ESCON channel interface, this flag indicates that at least one mainframe has established an ESCON logical path corresponding to the paths specified in one of the device configuration statements (CLAW, offload, CSNA, CMPC, or CMPC+). For a parallel channel interface, this flag indicates that the x'0100' path is defined in at least one device configuration statement and SIGNAL is present. •RQC_PEND—CMCC adapter is attempting to send status to the channel on this interface. This state should not persist for more than a few seconds. This flag is not applicable to the virtual channel interface. •RESET_EVENT—Indicates that a reset event has been received. •SIGNAL—For an ESCON channel interface, this flag indicates that light is detected. For a parallel channel interface, this flag indicates that the "operational out" signal is detected. This flag matches the state of the "signal" LED. It will be set only if the LOADED flag is also set. This flag is not applicable to the virtual channel interface. •STAT_PEND—CMCC adapter has status to present for this device. The indication is cleared when the mainframe accepts the status. |
Flags (continued) |
•SUSPEND—Indicates that the CMCC device task has decided to suspend data transfer for a particular device. •VALID—A physical interface is installed. All displays for physical channel interfaces should contain this. This flag matches the state of the "present" LED. |
Link: xx |
Director port number to which the physical channel is connected. If the physical channel is directly connected, then this value is host dependent. |
Buffers |
Number of times the CMCC adapter has dropped a packet bound for the Route Processor because no packet switching buffer was available on the Route Processor. |
CRC errors |
Number of cyclic redundancy check (CRC) errors detected on the channel for ESCON. Number of parity errors detected on the channel for parallel. |
Load count |
For a CMCC physical channel interface, the number of times the channel adapter microcode has been loaded. |
Link Incident Reports |
Link incidents are errors on an ESCON channel. These errors are reported to the host operating system and are recorded here for additional information. •Implicit incidents—Recoverable error occurred in the ESCON Channel Adapter (ECA). •Bit errors—Bit error rate threshold was reached. The bit error rate threshold is 15 error bursts within 5 minutes. An error burst is defined as a time period of 1.5 +/- 0.5 seconds during which one or more code violations occurred. A code violation error is caused by an incorrect sequence of 10 bit characters. •Link failed—Loss of synchronization or light has occurred. •NOS—Channel or switch sent the Not Operational Sequence. •Sequence timeout—Connection recovery timeout has occurred or the router is waiting for the appropriate response while in the send offline sequence (OLS) state. •Invalid Sequence—Unconditional disconnect (UD) or unconditional disconnect response (UDR) is recognized in the wait for offline sequence state. |
Neighbor node |
Describes the channel or switch. Valid values are: •VALID—Information has been exchanged between the router and channel or switch. •Class—Switch or channel depending on whether the connection is a switched point-to-point connection or a point-to-point connection. •Type number—Model of switch or processor. •TAG—Physical location of the connector. •Model—A further classification of type. •Manufacturer—Identifies who made switch or processor. •Plant and sequence—Manufacturer-specific information to uniquely define this one device. |

|
Stack Address |
Real IP address of the TCP/IP stack or offload device. |
Local IP Addr |
Local IP address on the connection. |
State |
The state of this TCP connection. The only value that may be set by a management station is deleteTCB(12). Accordingly, it is appropriate for an agent to return a "badValue" response if a management station attempts to set this object to any other value. If a management station sets this object to the value deleteTCB(12), then this has the effect of deleting the Transmission Control Block (TCB) (as defined in RFC 793) of the corresponding connection on the managed node, resulting in immediate termination of the connection. As an implementation-specific option, a reset (RST) segment may be sent from the managed node to the other TCP endpoint. (Note, however, that RST segments are not sent reliably.) |
In Bytes |
Number of bytes sent for this TCP connection.
Note To support Simple Network Management Protocol (SNMP) Version 1 Managers, this variable is supplied as a 32-bit value that can wrap frequently.
|
Out Bytes |
Number of bytes received for this TCP connection.
Note To support SNMP Version 1 Managers, this variable is supplied as a 32-bit value that can wrap frequently.

Usage Guidelines
The show extended channel tn3270-server pu command is valid only on the virtual channel interface. The display shown depends on whether the PU is a direct PU or a Systems Network Architecture (SNA) session switch PU.
The output from the show extended channel tn3270-server pu command varies based on use of the optional cluster keyword. Without the cluster keyword, the output column headings for the LU information appear as "model," "frames in out," and "idle for."
When you use the cluster keyword, the output column headings for the LU information appear as "cluster," "pool," and "count." The cluster heading lists the specific cluster within the pool to which the LU belongs, along with the specific cluster layout after the slash.
The pool heading identifies the corresponding pool name, and the count heading identifies the cluster number out of the total number of clusters in the pool.
There is not a no form for this command.

This command displays information about client subnet client groups. This includes all configured groups and the CLIENT SUBNET OTHER group. If no optional parameters are specified, a complete list of client subnet client groups is displayed along with their collection control parameters. If you specify values for the ip-address keyword and ip-mask argument, only client groups containing that subnet are displayed. If you specify the detail keyword, each client group entry is followed by a list of its client members and their response-time statistics.
Examples
The following is sample output from all configured client groups using the show extended channel tn3270-server response-time subnet command:
Router# show extended channel 3/2 tn3270-server response-time subnet
subnet 10.10.10.0 255.255.255.192
aggregate NO excludeip NO dynamic definite response NO
sample period multiplier 30
bucket boundaries 10 20 50 100

Descriptions
|
|
|
subnet |
Displays the IP address and IP mask of the client subnet group for which response-time statistics are being shown. |
aggregate |
Displays whether the response time statistics for the clients in this response-time group are reported collectively for the group (YES) or individually by client (NO). This value is automatically set to NO by the TN3270 server for subnet client response-time groups. |
excludeip |
Displays whether the IP component (the client/server path) is included in the response time for any transaction (NO) or if only the Systems Network Architecture (SNA) component (the server/host path) is included in the response time for any transaction (YES). This value is automatically set to NO by the TN3270 server for subnet client response-time groups. |
dynamic definite response |
Displays whether the server adds a Definite Response request to the first-in-chain (FIC) reply in each transaction, to get a response from the client so that the IP component can be included in the response time. The value is automatically set to NO by the TN3270 server for all types of response-time groups. |
sample period multiplier |
Displays the number that is multiplied by an interval of 20 seconds to determine the collection interval for the response-time group. The multiplier value is defined using the response-time group command. For example, a sample period multiplier of 30 results in a collection interval of 600 seconds (30 x 20 seconds), or 10 minutes, for this client group. |
bucket boundaries |
Displays the value of the response-time bucket boundaries in tenths of seconds. The bucket boundaries are defined using the response-time group command. |
buckets |
Displays the number of transactions in each response-time bucket for the specified application group. |
average total response time |
Displays the average response time (in tenths of seconds) for the total number of response-time transactions. |
average IP response time |
Displays the average response time in tenths of seconds (including IP transit time) for the total number of response-time transactions. |
number of transactions |
Displays the total number of response-time transactions across all response-time buckets. |
