I am sure someone have implemented this earlier and come across this issue. I have 6500 and 3750 connected via trunk. I configured following for my RSPAN sesssion.
monitor session 3 source interface f7/1, f8/31, Fa7/46
monitor session 3 destination interface vlan 800
monitor session 3 source remote vlan 800
monitor session 3 destination interface FastEthernet1/0/10
As you can predict my sniffer is connected on f1/0/10 port of 3750. Issue is as soon as I define 'monitor session 3 destination interface FastEthernet1/0/10' on 3750, it will disable that port and my sniffer no longer connect to the network(can't connect with default gateway).
What am I missing here?
