Update your HP Procurve SNMP Trap Server List

Problem: I had some outdated SNMP trap servers on my procurve switches, from when I was experimenting with different monitoring software. HP Intelligent Management for some reason won't remove them in the GUI, so I had to do it via command line. Here's how to do it;

Solution: 

Telnet to the switch, login as a switch Admin and enter config mode (by typing "config" at the prompt).

"show snmp-server" will list your servers. Take note of the IP address and community listed by each.

For 5308xl and 5412zl switches:

"no snmp-server host 123.456.123.23 community public" will remove the server.

"snmp-server host 123.456.123.23 community public" will add the new server.

For 4108GL and 2524 switches:
"no snmp-server host 123.456.123.23 public" will remove the server.
"snmp-server host 123.456.123.23 public" will add the new server.
