CPU and Memory Utilization on the ML-MR-10 Card

This appendix provides the CPU and memory utilization percentage values when the CPU intensive feautres are configured on the ML-MR-10 card.

You can configure the CPU intensive features on the ML-MR-10 card. When you configure the CPU intensive features, ensure that the total CPU utilization does not go beyond 80 percent. The following sections provide information about configuring CPU intensive features on the ML-MR-10 card.

•CPU Utilization for EVC and QoS on the ML-MR-10 Card

•CPU Utilization for HW-LCAS Circuits on POS Ports and RPR

•The ML-MR-10 card raises an alarm when you configure the memory intensive features. The ML-MR-10 card does not display the expected behavior when the memory utilization is more than 85 percent.

•Memory Utilization for EVC and QoS

•Memory Utilization for HW-LCAS Circuits on POS Ports and RPR

CPU Utilization for EVC and QoS on the ML-MR-10 Card

Table A-1 provides the CPU utilization percentage values for EVC and QoS on the ML-MR-10 card.

CPU Utilization for HW-LCAS Circuits on POS Ports and RPR

Table A-2 provides the CPU utilization values on POS ports and RPR configured with the ML-MR-10 card with HW-LCAS circuits.

Example of CPU Utilization with CPU Intensive Features Configured

Base + VCAT/LCAS (50 memebers)

20% is base

50 members of VCAT/LCAS take 40%

Rest of 20% can be used to configure CFM features (depending on the CPU percentage 
required to configure that particular CFM feature. For example, F1 requires40%, F2 
requires 30%, F3 requires 20%).

Memory Utilization

The ML-MR-10 card raises an alarm when you configure the memory intensive features. The ML-MR-10 card does not display the expected behavior when the memory utilization is more than 85 percent.

Memory Utilization for CFM Features

Monitor the memory utilization percentage when the CFM features are configured with various MEP and MIP using the graphs illustrated in Figure A-1 and Figure A-2.

Figure A-1 Number of MEPs and Available Memory

Figure A-2 Number of MIPs and Available Memory

Memory Utilization for EVC and QoS

Table A-3 provides the memory utilization percentage values for EVC and QoS on the ML-MR-10 card.

Memory Utilization for HW-LCAS Circuits on POS Ports and RPR

Table A-4 provides the memory utilization percentage values with POS ports and RPR configured on the ML-MR-10 card with HW-LCAS circuits.
