And - yes that message is super confusing. Given that it is a 40g interface I'm guessing Gen1, so you cannot use netflow.
This is from a live 9300-EX(GEN2): SPAN not running, with 8 ports running SFLOW. sh run all | in "tcam region s" hardware access-list tcam region span 0 hardware access-list tcam region svi 0 hardware access-list tcam region sflow 0 hardware access-list tcam region span 512 hardware access-list tcam region span-sflow 0 Here is the same output on a 9300 (GEN 1) This device is not running Sflow - and Is running SPAN sh run all | in "tcam region s" hardware access-list tcam region span 256 hardware access-list tcam region svi 0 hardware access-list tcam region sFlow Northstar 0 hardware access-list tcam region span 0 -----Original Message----- From: cisco-nsp <[email protected]> On Behalf Of Nick Cutting Sent: Friday, April 5, 2019 3:25 PM To: Satish Patel <[email protected]>; Cisco Network Service Providers <[email protected]> Subject: Re: [c-nsp] Cisco Nexus 9K tcam carving question This message originates from outside of your organisation. 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? -----Original Message----- From: cisco-nsp <[email protected]> On Behalf Of Satish Patel Sent: Friday, April 5, 2019 3:15 PM To: Cisco Network Service Providers <[email protected]> Subject: [c-nsp] Cisco Nexus 9K tcam carving question This message originates from outside of your organisation. 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. _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/ _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/ _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
