TCAM exhaustion on stack member

Hi team,

Just wonder how stack switches allocate tcam? Doesn't two stack member share the same TCAM?

We recently encountered one issue that only one stack member was having TCAM exhaustion issue (IPV4 route) while the other one looks fine.

"remote command all show platform ip unicast failed route" only shows one switch is failing to inject fib entries to TCAM, why?

Hi, This is an odd behaivor

Hi,

 

This is an odd behaivor since all stack members use the same SDM desktop or aggregator template that is stored on the stack master, in case a new switch is added to a stack, as with the switch configuration and VLAN database files, the SDM configuration that is stored on the stack master overrides the template configured on an individual switch.

Can you take this command remote command all show platform tcam util asic all, and post it?

 

Regards,
