Swaroop,
I think I can help you out with this one and I feel good that I can pay you
back a little for all the help you've given me.
The key thing to remember with remote spanning is this requires a vlan
dedicated to the remote span traffic. Now, unless you've prohibited the vlan
for remote span from the trunks and vtp is running on all the switches, it
shouldn't matter that the source switch is multiple hops away from the
destination switch since vtp will propagate the rspan vlan to all switches.
Once you've created the rspan vlan, then just follow the directions in the CG
for configuring the source switch and destination switch.
This is from the 3550 CR,
Usage Guidelines
When a VLAN is converted from a normal VLAN to an RSPAN VLAN (or the reverse),
the VLAN is first deleted and is then recreated with the new configuration. If
VTP is enabled, the RSPAN feature is propagated by VLAN Trunking Protocol
(VTP) for VLAN-IDs that are lower than 1024.
Before you configure the RSPAN remote-span feature, use the vlan (global
configuration) command to create the VLAN.
Examples
This example shows how to configure an RSPAN VLAN.
Switch(config)# vlan 901
Switch(config-vlan)# remote-spanLet me know if you have any other questions on
this.HTH, Tim
