We have an infrastructure of Cisco 4500 switches and are using an RSPAN VLAN to capture packets from a port on any switch to a single capture system (Wireshark). It works great and reduces the effort and equipment needed to capture on any port in the core. The problem is that in order to find out which ports are spanned to the RSPAN VLAN, we have to login to each switch and show monitor;
Session 1
---------
Type : Remote Source Session
Source Ports :
Both : Gi3/27
Filter Pkt Type :
RX Only : Good
Dest RSPAN VLAN : 99
Does someone know a way to see at a glance what the monitor status is on multiple switches? I can't seem to find an SNMP OID for that info and we don't have a config manager that can pull that info from multiple switches. Anybody have a way to do this?
