Defining Snmp Communities - Cisco 4700M Administration Manual

Chapter 7 Configuring SNMP
Examples
The following example shows how to set the SNMP user information:
host1/Admin# config
Enter configuration commands, one per line. End with CNTL/Z
host1/Admin(config)# snmp-server user sam Network-Monitor auth md5 abcdefgh
host1/Admin(config)# snmp-server user Bill Network-Monitor auth sha abcd1234 priv abcdefgh

Defining SNMP Communities

This section describes how to create or modify SNMP community names and access privileges. Each
SNMP device or member is part of a community. An SNMP community determines the access rights for
each SNMP device. SNMP uses communities to establish trust between managers and agents.
You supply a name to the community. After that, all SNMP devices assigned to that community as
members have the same access rights (as described in RFC 2576). The ACE allows read-only access to
the MIB tree for devices included in this community. The read-only community string allows a user to
read data values, but prevents that user from modifying modify the data.
If you change the SNMP engine ID for an Admin or user context, all configured SNMP communities are

deleted. You must recreate all SNMP communities by using the snmp-server community command in
configuration mode. For more information on the SNMPv3 engine ID, see the

SNMP communities are applicable for SNMPv1 and SNMPv2c only. SNMPv3 requires user
configuration information such as specifying the role group that the user belongs to, authentication
parameters for the user, authentication password, and message encryption parameters (see the
"Configuring SNMP Users"
Only network monitoring operations are supported through the ACE implementation of SNMP. In
this case, all SNMP users are automatically assigned the system-defined default group of
Network-Monitor. For details on creating users, see the Cisco 4700 Series Application Control
