COMMUNITY STRING

TYPES

There are three community strings for SNMPv1-v2c-speaking devices:

◆ SNMP Read-only community string enables a remote device to retrieve

"read-only" information from a device. The NMS uses this to request

information from devices in the network.

◆ SNMP Read-Write community string allows a remote device to read

information from a device and to modify settings on that device. To be

able to modify any settings on a device the read-write community

strings should be set to “public.”

◆ SNMP Trap community string is used when sending SNMP Traps to

another device. NMS accepts any SNMP Trap community string.

By convention, most SNMPv1-v2c equipment ships from the factory with a

read-only community string set to “Public.” It is standard practice for

network managers to change all the community strings so that outsiders

cannot see information about the internal network. (In addition, network

managers may employ firewalls to block any SNMP traffic to ports 161 and

162 on the internal network.)
