What is the SPAN session limit on the C6880-X? I have two running in VSS. I googled and I saw that the limit is 2 if it is SUP2 supervisor. How do I know what supervisor module that I am using? "show inventory" says "C6880-X-SUP"
Also in the document about the SUP2 limit, it says "Local SPAN Egress-Only" limit is 14. What is Egress-only session? Does it just mean the SPAN source is "interface te1/1 tx"? Thanks

that means you need to enter local only
Enter the local-tx keyword to configure egress-only SPAN sessions.

Thanks Balaji. On my 6880 I don't have the option available. Actually, the config syntax is different. It looks like Nexus switch configuration. Can I assume that I am not using SUP2 in my switch?
Thanks for the links however I still don't know what local-tx is. Is it related to SPAN on FEX? Does "local" mean that the source and destination interface have to be on the same FEX?

Can you post show version - C68XX is not nexus.
to know the modules, show modules post the output here.
68XX do support have FEX - but we need to know your environment to suggest better here.

I am mentioning SUP2 because in this document it says it is for Cat 6500 however the config seems to be for Nexus switch.
Here are my show version and show module output
