4500G SNMP Problem

[Prep]

I'm having a problem getting one of my management utilities ( OpUtils ) to monitor my 3Com 4500G switches. We have 10 4500G's. Each time it tries to read the community name of a 4500G, it comes back and says "No response to SNMP queries". I'm trying to use SNMP v1



Here is how I have SNMP configured in the switch



snmp-agent

snmp-agent local-engineid 8000002B03001AC1A29741

snmp-agent community read public

snmp-agent community write private

snmp-agent sys-info contact Frank

snmp-agent sys-info location Scarpa MDF

snmp-agent sys-info version all

snmp-agent target-host trap address udp-domain 10.5.0.8 params securityname public

snmp-agent mib-view excluded dot1dTpFdbTable iso

#

user-interface aux 0

authentication-mode scheme

user-interface vty 0

authentication-mode scheme

screen-length 60

protocol inbound telnet

user-interface vty 1 4

authentication-mode scheme

protocol inbound ssh

#

return





Any help someone can give in helping me diagnose this is greatly appreciated! :)
