RE: RSPAN

Not sure if this is what you are asking but it does look like you are
missing something.

I think when using rspan you will need the "remote" option on both ends to
specify that the transport vlan is in-fact an rspan enabled vlan....which
brings up another point....did you make the transport vlan rspan enabled? I
believe you must.

SW1

monitor session 1 source vlan 22 rx

monitor session 1 source vlan 66 rx

monitor session 1 destination remote vlan 99

"remote" missing here..adding it in for you.

SW2

monitor session 1 source remote vlan 99

monitor session 1 destination interface fastEthernet 0/2

SW1#sh vlan remote-span

Remote SPAN VLANs

----------------------------------------------------------------------------

SW1#conf t
SW1(config)#vlan 3
SW1(config-vlan)#remote-span
SW1(config-vlan)#exit
SW1(config)#do sh vlan remo
 
Remote SPAN VLANs
