    SPAN Filter VLAN

    Sajith

      Hi All,

       

      According the CCIE Routing & Switching V5 volume 1, when you configuring a Trunk port as a SPAN source you can filter (remove ) VLANs as per the page number 26

      We also filter (remove) VLANs 1, 2, 3, and 229 from the traffic coming from the fa0/19 trunk port. "

       

      Example 1-4 Complex SPAN Configuration Example

      MDF-ROC3# config term

      MDF-ROC3(config)# monitor session 11 source interface fa0/18 rx

      MDF-ROC3(config)# monitor session 11 source interface fa0/9 tx

      MDF-ROC3(config)# monitor session 11 source interface fa0/19

      MDF-ROC3(config)# monitor session 11 filter vlan 1 - 3 , 229

      MDF-ROC3(config)# monitor session 11 destination interface fa0/24 encapsulation replicate.

       

      In-fact, it is working in reverse manner in IOS 15. It is not filtering vlan 1-3 , 229 instead it only monitoring those VLANs and removing others VLANS.

      Can someone clarify this please!

       

      Thank you

      Cheers
