Configuring SNMP Communities

N M P
ETWORK ANAGEMENT ROTOCOL
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 assigns 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:
Table 9-3 Parameters contained in SNMP Community Configuration

Context
(SNMP)
Description
The name assigned to the SNMP community. An
SNMP community name may contain up to 32
alphanumeric characters.
The name assigned to security group for the
associated SNMP community. A security group
name may contain up to 32 alphanumeric
characters
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.
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.
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.
