[c-nsp] Cisco Nexus 9K tcam carving question

[Nick Cutting]

Are you using a span session?

If so - then you cannot run SFLOW at the same time.

Is this a GEN1 or GEN2 9300? EX or FX?

Folks,

I want to enable sFlow on Cisco nexus 9300 switch on 40G interface
(GEM) module. but getting following error.

(config)# sflow data-source interface e2/5 In order to enable sFlow sampling on North star front panel port(Ethernet2/5), please either carve both span and sflow tcam regions with non-zero sizes using the commands 'hardware access-list tcam region span <size>'
'hardware access-list tcam region sflow <size>'
or remove both span and sflow tcam regions and carve a span-sflow tcam region with a non-zero size using the commands


When i am doing following, got error that means i don't have space in my tcam table so what is the best approve here?

(config)# hardware access-list tcam region sflow 256
ERROR: Aggregate TCAM region configuration exceeded the available Ingress TCAM slices. Please re-configure.
