I am setting a mirror/span port to capture traffic on a 6807 switch. I setup the span part using the commands below but do i have to configure anything on the actual interfaces? I am assuming I would setup the source port as an access vlan port jus...

We have a pair of 3750Gs that we are seeing some orange lights on. There is a trunk between the two switches and off of each port a loop hangs, ie port 5 on the first switch is connected to a bunch of other switches that eventually come back to port...

There is a trunk directly between the two switches passing several vlans. There are also four ports on each switch setup as access vlan that connect to each other through a series of non-Cisco switches not running spanning-tree. So basically port 5...
