11.2.8 Defining SNMP
11.2.8.1 Configuring SNMP Community Configuration Page
By default, two SNMP Communities exist:
− private, with 'Read/Write ' privileges and status set to enable
− public, with 'Read Only' privileges and status set to enable
These are well-known communities, you can use this menu to change the defaults or to add other
communities. Only the communities that you define using this menu will have access to the switch using
the SNMPv1 and SNMPv2c protocols. Only those communities with read-write level access will have
access to this menu via SNMP.
You should use this menu whe n you are using the SNMPv1 and SNMPv2c protocol: if you want to use
SNMP v3 you should use the User Accounts menu.
