Cisco 6513 Span session Limit

[fhoban]

Hi All,

I have a need to capture some traffic but my core 6513's are already using the limit of 2 span sessions. I can't edit any of the sessions either because I want to source traffic from vlans and you can only do one or the other.

Is using a VACL with 'switchport capture' on the destination interface an option ?

E.g. I want to source traffic from vlan 10,20,30,40 and send the all to interface Gi10/10 ?? Anybody used something like this before and is there any caveats ? I dont need to be too granular with the ACL's but just capture all traffic in those vlans.

Appreciate the help!

Hello ,

2 full span sessions (Rx & Tx) are indeed the limit in 6500 series switch. Check out the below link for more information
