[c-nsp] questions regarding RSPAN on Catalyst 2950, 3550, 3560, 3750 and 4500 platforms

[Martin T]

Hi,

I made two RSPAN test-setups both using somewhat different Cisco platforms.


1) First setup: http://i.imgur.com/XFCD8.png

If I send ICMP "echo request" messages from "T60" to "PC" or for
example telnet to "PC" TCP port 80, then all the traffic is
beautifully mirrored to "WS-C3550-24-2" port Fa0/2 and I'm able to see
the traffic in "HP" machine. In other words RSPAN between two
WS-C3550-24 switches works fine. However, there is no "T60" and "PC"
traffic captured in "PE860" machine- only STP frames show up. VLAN 15
with "remote-span" option is configured to all four switches. Any
ideas what might cause this?



2) Second setup: http://i.imgur.com/a3KjV.png

As you can see, second setup is similar to the first one, but switches
are different. If I make some traffic between "T60" and "PC", then
"PE860" sees only IPv6 traffic! Am I doing something wrong or is this
some sort of (known) bug? IOS in Cisco 4506 is 12.2(37)SG1.


thanks,
Martin
