Table 3. debug mpls ldp igp sync Field Descriptions

Field

Description

sync_achieved

The first line of the output for an interface shows the status of the MPLS LDP-IGP Synchronization feature in relation to the status of the interface.

notify status

Notify status shows the following MPLS LDP-IGP synchronization information for each interface:

  • If MPLS LDP-IGP synchronization is required.

  • If MPLS LDP-IGP synchronization has been achieved.

  • If the IGP should wait for MPLS LDP-IGP synchronization to be achieved.

  • The length of time the IGP should wait for MPLS LDP-IGP synchronization to be achieved.

internal status

Internal status displays the LDP internal synchronization status and the state of the timer. The internal status can be achieved or not achieved. The timer state can be running or not running.

The following example shows events associated with MPLS LDP-IGP synchronization on interfaces running OSPF when you configured a delay timer: 


Router# debug mpls ldp igp sync
*Jan 3 04:38:49.571: LDP-SYNC: Et0/0, OSPF 1: notify status (required, not achieved, no delay, holddown infinite) internal status (achieved, timer running)

Usage Guidelines

LDP manages peer sessions by means of two coupled state machines:

  • A low-level state machine that deals with session establishment and shutdown

  • A high-level state machine that deals with setting up and shutting down label advertisement

Use the debugmplsldpsessionstate-machine command to monitor the lower-level session state machine.

Use the debugmplsldppeerstate-machine command to monitor the higher-level session state machine.

Examples

The following shows sample output from the debugmplsldppeerstate-machine command: 


Router# debug mpls ldp peer state-machine
tagcon: start session TCP timers for 144.0.0.44:0 (pp 0x610EEC84)

Usage Guidelines

Use this command to monitor LDP information when a local label binding associated with a prefix is withdrawn and freed. LDP withdraws a previously advertised label before advertising a new label.

If you enter the debugmplsldpprev-label command without an optional keyword and argument, the command displays output for all previous label binding changes. Use the prefix-acl acl or peer-acl acl keywords and arguments to limit the output to prefixes defined by the respective ACLs.

Examples

The following is sample output from the debugmplsldpprev-label command: 


Router# debug mpls ldp prev-label
tagcon: Changing state to WITHDRAWN for prefix=10.0.1.1, label31
tagcon: Creating prev_lbl_info for prefix=10.0.1.1, label31

Usage Guidelines

Platforms that are not directly connected may engage in LDP label distribution (for example, to support two-level labeling across an LSP tunnel).

An LDP session between nondirectly connected label switch routers (LSRs) is called a targeted session and is supported by LDP extended discovery which uses targeted Hello messages sent to specific IP addresses.

An LSR (Router 1) attempting to initiate an LDP targeted session with another LSR (Router 2) sends targeted Hello messages sent to a specific IP address of Router 2. If the configuration of Router 2 permits it to respond to targeted Hello messages from Router 1, it does so, and the LDP session can be established. In this situation, Router 1 is said to be an active LSR for the targeted session because it initiated the targeted Hello messages; Router 2 is said to be a passive LSR for the session because it responded to them.

As with LDP sessions between two directly connected LSRs, it is possible for a targeted session to be the result of multiple discovery activities which are targeted to different IP addresses for the same LSR. In addition, it is possible for both LSRs in a targeted session to be active and for both to be passive.

Usage Guidelines

Use this command to monitor LDP activity relating to the establishment of the transport (TCP) connection for LDP sessions.

When two devices establish a TCP connection for an LDP session, the device with the larger transport address plays an active role and the other plays a passive role. The active device attempts to establish a TCP connection to the well-known LDP port at the passive device. The passive device waits for the connection to the well-known port to be established.

The following table lists the messages displayed by the debugmplslspverror command and the reason for each error message.

Table 18. Messages Displayed by the debug mpls lspv error Command

Message

Reason Why Message Is Displayed

Echo reply discarded because not routable

An echo reply message is sent because the IP header indicates that the packet has the Router Alert set and the packet is not routable.

UDP checksum error, packet discarded

A packet is received on the port being used by Label Switched Path Verification (LSPV) and there is a checksum error on the packet.

Invalid echo message type

An MPLS echo packet with an invalid echo message type (neither a request nor a reply) is received.

Illegal Action

The state machine that drives the LSPV software detects an invalid condition.

Usage Guidelines

The optional> interface parameter restricts the display to only those packets received or sent on the indicated interface or subinterface.


Note

Use this command with care because it generates output for every packet processed. Furthermore, enabling this command causes fast and distributed label switching to be disabled for the selected interfaces. To avoid adversely affecting other system activity, use this command only when traffic on the network is at a minimum.

Examples

The following is sample output from the debugmplspackets command: 


Router# debug mpls packets
TAG: Hs3/0: recvd: CoS=0, TTL=254, Tag(s)=27
TAG: Hs0/0: xmit: (no tag)
TAG: Hs0/0: recvd: CoS=0, TTL=254, Tag(s)=30
TAG: Hs3/0: xmit: CoS=0, TTL=253, Tag(s)=27

The following table describes the significant fields shown in the display.

02:24:22: SM: ---TE ION Process Restart 0x78EF9050: process cfg replay start (4)
02:24:22: SM:    AWAIT-CFG (3) --> CFG (4)
02:24:22: TE ION Restart timer started, proc_idx:0 delay:300000
02:24:22: SM: ---TE ION Process Restart 0x78EF9050: reg invoke succeeded (2)
02:24:22: SM:    CFG (4) --> CFG (4)
02:24:22: SM: ---TE ION Process Restart 0x78EF9050: process cfg replay done (5)
02:24:22: SM:    CFG (4) --> SYNC (5)
02:24:22: TE ION Restart timer started, proc_idx:0 delay:900000

The output shows typical process restart information that your technical support representative might request if you report a problem after an IP routing process restart. The information displayed can vary, depending on the conditions that caused the restart.

Usage Guidelines

This command monitors requests to establish or remove cross-connects from XmplsATM interfaces to the Virtual Switch Interface (VSI) master, as well as the VSI master responses to these requests.


Note

Use this command with care, because it generates output for each cross-connect operation performed by the label switch controller (LSC). In a network configuration with many label virtual circuits (LVCs), the volume of output generated can interfere with system timing and the proper operation of other router functions. Use this command only in situations in which the LVC setup or teardown rate is low.

Examples

The following is sample output from the debugmplsxtagatmcross-connect command: 


Router# debug mpls xtagatm cross-connect

12.4(20)T

This command was removed.

Usage Guidelines

Use the debugmplsxtagatmevents command to monitor major events that occur on XmplsATM interfaces. This command monitors events that pertain only to XmplsATM interfaces as a whole and does not include any events that pertain to individual XmplsATM VCs or individual switch cross-connects. The specific events that are monitored when the debugmplsxtagatmevents command is in effect include the following:

  • Receiving asynchronous notifications that the VSI master sent through the external ATM application programming interface (ExATM API) to an XmplsATM interface.

  • Resizing of the table that is used to store switch cross-connect information. This table is resized automatically as the number of cross-connects increases.

  • Marking of XmplsATM VCs as stale when an XmplsATM interface shuts down, thereby ensuring that the stale interfaces are refreshed before new XmplsATM VCs can be created on the interface.

Examples

The following is sample output from the debugmplsxtagatmevents command: 


Router# debug mpls xtagatm events
XTagATM: desired cross-connect table size set to 256
XTagATM: ExATM API intf event Up, port 0xA0100 (None)
XTagATM: ExATM API intf event Down, port 0xA0100 (None)
XTagATM: marking all VCs stale on XTagATM0

The following table describes the significant fields shown in the display.

Table 22. debug mpls xtagatm events Field Descriptions

Field

Description

XTagATM

The source of the debugging message.

desired cross-connect table size set to 256

The table of cross-connect information has been set to hold 256 entries. A single cross-connect table is shared among all XmplsATM interfaces. The cross-connect table is automatically resized as the number of cross-connects increases.

ExATM API

The information in the debug output pertains to an asynchronous notification sent by the Virtual Switch Interface (VSI) master to the XmplsATM driver.

event Up/Down

The specific event that was sent by the VSI master to the XmplsATM driver.
