Configuring Community Strings
You use the SNMP community string to define the relationship between the SNMP manager and the
agent. The community string acts like a password to permit access to the agent on the access point.
Optionally, you can specify one or more of these characteristics associated with the string:
• An access list of IP addresses of the SNMP managers that are permitted to use the community string
to gain access to the agent
• A MIB view, which defines the subset of all MIB objects accessible to the given community
• Read and write or read-only permission for the MIB objects accessible to the community
Note In the current Cisco IOS MIB agent implementation, the default community string is for the Internet
MIB object sub-tree. Because IEEE802dot11 is under another branch of the MIB object tree, you must
enable either a separate community string and view on the IEEE802dot11 MIB or a common view and
community string on the ISO object in the MIB object tree. ISO is the common parent node of IEEE
(IEEE802dot11) and Internet. This MIB agent behavior is different from the MIB agent behavior on
access points not running Cisco IOS software.
Beginning in privileged EXEC mode, follow these steps to configure a community string on the access
point:
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
snmp-server community string
[ access-list-number ]
[ view mib-view ]
[ro | rw]
Configure the community string.
• For string, specify a string that acts like a password and
permits access to the SNMP protocol. You can configure one
or more community strings of any length.
• (Optional) For access-list-number, enter an IP standard access
list numbered from 1 to 99 and 1300 to 1999.
• (Optional) For view mib-view, specify a MIB view to which
this community has access, such as ieee802dot11. See the
“Using the snmp-server view Command” section on
page 18-10 for instructions on using the snmp-server view
command to access Standard IEEE 802.11 MIB objects
through IEEE view.
• (Optional) Specify either read-only (ro) if you want
authorized management stations to retrieve MIB objects, or
specify read/write (rw) if you want authorized management
stations to retrieve and modify MIB objects. By default, the
community string permits read-only access to all objects.
Note To access the IEEE802dot11 MIB, you must enable either
a separate community string and view on the
IEEE802dot11 MIB or a common view and community
string on the ISO object in the MIB object tree.
