Manually allocate TCAM for unicast MAC addresses

[Difan Zhao]

Hi experts,

I have the "Desktop Routing" sdm template enabled on my 3750 switch stack mainly because I need to use the "policy routing" feature. However I didn't realize until now that the I only have 200 available MAC addresses left on my switch. I will have more devices in so the total number of MAC addresses will exceed the size of the TCAM. Is there a way I can move some bytes from other features such as QoS and ACL to MAC address table?

Or is the VLAN template supporting "policy routing"?

Thanks,

Difan

You cannot manually allocate the TCAM resources. You have to use " routing template" for PBR but it only supports 3K unicast mac-addreses. Check if that fits your requirement. Use the below link.
