Amount of buffers on ASR9001

Hi,

I need to find out the amount of buffers on the ASR 9001 platform, both for integrated ports and

A9K-MPA-4X10GE.

Do anyone have these available?

Amount of buffers on ASR9001

hi daniel,

the 9001 is based on the MOD80 linecard.

This linecard has 2 NPU's for the feature processing.

Each MPA bay has a dedicated NPU and also serves 2 of the 4 onboard 10GEs.

This NPU has several pieces of memory attached like a TCAM, stats memory, 2xsearch memory for each MAC and L3 FIB

and there is also buffer memory.

This buffer memory is shared is 1G in the TR version and 2G on the SE version of the linecard.

The "LC type" for the 9001 is the SE version hence you have 2G of buffer memory that can be used for all interfaces

depending on their qos policy-map configuration and more particular the queue-limit that is assigned to it.

you can use the command show qos int to see what the hw programmed for queue limit.

regards
