3524 port monitor

I need to monitor a trunk port traffic on old 3524 switch, it appear that in order to do monitoring on this switch the monitoring port needs to be in the same vlan as the monitored port, thus not allowing me to monitor the trunk traffic. Is there a way of accomplishing it?

Re: 3524 port monitor

Hi Chris,

Unfortunately, there is no way around this.

http://www.cisco.com/warp/public/473/41.html#topic1

"A monitor port cannot be a multi-VLAN port.

A monitor port must be a member of the same VLAN as the port monitored. VLAN membership changes are disallowed on monitor ports and ports being monitored."

HTH,

Bobby

Re: 3524 port monitor

Hi Chris,

I do not think there is any workaround for this limitation.

Being such an old box I do not think Cisco think of working on this boxes.

SPAN on this box can be only configured on access ports.

Ankur
