Using SNMP
The EX2500 switch provides SNMPv1, SNMPv2, and SNMPv3 support for access
through any network management software, such as IBM Director or
HP-OpenView.
SNMPv1, SNMPv2
To access the SNMP agent on the EX2500 switch, the read and write community
strings on the SNMP manager should be configured to match those on the switch.
The default read community string on the switch is public, and the default write
community string is private.
The read and write community strings on the switch can be changed with the
following commands on the CLI:
ex2500(config)# snmp-server read-community <1-32 characters>
and
ex2500(config)# snmp-server write-community <1-32 characters>
The SNMP manager should be able to reach the management interface or any one
of the IP interfaces on the switch.
