Local port mirroring

    Hello,

    I'm running local port mirroring (advanced port mirroring) on my local vlan.

     

    What i'm doing is ignore list of IPs, and for the rest I'm mirroring the data to local computer connected directly to port 1 in the switch.

    E.g

    class ipv4 all-except18and19

       10 ignore ip any 10.166.192.18/32

       15 ignore ip any 10.166.192.19/32

       20 ignore ip 10.166.192.18/32 any

       25 ignore ip 10.166.192.19/32 any

      100 match ip any any

     

    Its working well, my question is, there is a limit for number of IPs I can set in the ignore list? for e.g can I set 1000 Ips in ignore list session? it will effect performance somehow?

     

    Thanks in advance,

    John

    Policy or ACL processing is done in TCAM and is line-rate so there won't be any impact of performance.
