172 CHAPTER 9: SIMPLE NETWORK MANAGEMENT PROTOCOL (SNMP)
Configuring SNMP Communities

SNMP versions 1 and 2c use a community to control access to a MIB object.

A community is a pairing relationship between an SNMP agent and an SNMP

application. The network administrator as signs the community a name. The

community assigns specific rights and privileges to authenticate SNMP

messages. The community passes on the messages to an associated group.

You set the following parameters to configure SNMP Communities:

Tabl e 9 -3 Par ameters contained in SNMP Community Configuration
Parameter Description
Name The name assigned to the SNMP community. An
SNMP community name may contain up to 32
alphanumeric characters.
Security Name The name assigned to security group for the
associated SNMP community. A security group
name may contain up to 32 alphanumeric
characters
IP Address The IP address of a host that is a member of the
SNMP community.
If you do not specify an IP address, all hosts are
allowed access using the community string.
Mask The mask for the specified IP address. The mask
allows you to specify a range of hosts. For
example, you can specify an IP address of
220.220.0.0 with a mask of 255.255.0.0. This
IP-mask address combination allows any host
from 220.220.0.0 through 220.220.255.255 to
access MIB objects in the specified SNMP
community.
Context The name of the SNMP context that is used with
the specified community when accessing the
security group.
The context is one of the parameters that allows
access to a group entry, along with group name,
security model and security level.
NOTE: Refer to the section “Configuring SNMPv3
Contexts” on page 178, for detailed information
about SNMP contexts.
