We have begun to implement BPDU Guard and UDLD guard in order to prevent layer 2 loops across our network, but have run across an issue with monitoring this solution.
I cannot see any command to enable the switches to send an SNMP trap whenever a port goes into Error Disable mode. This is something I'd consider critical in troubleshooting potential loops, or unauthorised addition of switches to the network.
If there is a way of getting IOS switches to send Err-Disable SNMP traps, then I'd really like to know what commands to enter for it to do this.
We use Cisco Catalyst 3750 PoE switches, with a mix of 24-port and 48-port models, with a mix of standard and enhanced images. We also use 3560 PoE switches. These switches are all less than 1 year old.
