SNMP Community Table Configuration
Use this table to create an SNMP community string to define the relationship between the SNMP manager and
an agent. The community string acts like a password to permit access to the agent on the switch. One or more of
the following characteristics can be associated with the community string:
An Access List of IP addresses of SNMP managers that are permitted to use the community string to gain access
to the switch’s SNMP agent.
An MIB view that defines the subset of all MIB objects that will be accessible to the SNMP community.
Read/write or read-only level permission for the MIB objects accessible to the SNMP community.
