Dear Nkansah,
From Doc CD, RSPAN infomation are propagated by VTP(vlan
1-1005). Moreover, in VTP client mode, you can't modify the vlan information.
http://www.cisco.com/univercd/cc/td/doc/product/lan/cat3560/12240se/scg/swspa
n.htm
For VLANs 1 to 1005 that are visible to VLAN Trunking Protocol (VTP),
the VLAN ID and its associated RSPAN characteristic are propagated by VTP. If
you assign an RSPAN VLAN ID in the extended VLAN range (1006 to 4094), you
must manually configure all intermediate switches.
I don't have 2 x
3550/3560 switch so i can't test it and show that it is working.
Regards,
Howard

%DCD!G RSPAN VLAN and VTP
Setup
HI,
I have 3 switches A, B, and C in a vtp domain, with switch A being
the vtp
server and the others clients.
I need to create a vlan for remote
span, which i do on the vtp server and it
propagates to the other switches.
However, an rspan vlan also requires marking the vlan as a special remote
span
vlan by using the 'remote-span' vlan mode command.
My question is, would the
*'remote-span'* attribute for the rspan vlan on
the server be propagated to
the other client switches when the vlan is
propagated by vtp?
Or do I have to
specifically go onto each of the client switches that would
be participating
in rspan and reenter the 'remote-span' command for the
rspan vlan they
receive? Note that the other switches are in client mode
which means I would
have to change mode to server if i have to do this on
them also?
How does the
rspan-marked vlan operate with vtp?
Waiting for your views and references.
Thanks
Felix
