ALL:
I've configured this many many times while studying and never had an issue until now. unfortunately I have always only used 2 switches when working on labs, this time I have 3 switches in my scenario. My souce - middle - destination switches are all VTP transparent. They all have vlan 998 configured as remote span vlan. Verified with show vlan remote-span. Source has the following monitor config: monitor session 1 source interface Fa0/2 (router2) monitor session 1 destination remote vlan 998 reflector-port Fa0/14 (it's a 3350) middle switch only has the remote-span vlan configured. Destination has the following monitor config: monitor session 1 destination interface Fa0/15 (IDS) monitor session 1 source remote vlan 998 this doesn't work. Now if I configure my source monitor on my middle switch it works just fine. (router 4) I am pinging between R2 and R4. Verified that all trunks carry vlan 998 and spanning-tree is in forwarding state. Any ideas? What could I be missing? - Matt
