Configuring SNMP
Default SNMP Configuration
Table 18-2 shows the default SNMP configuration.
Enabling the SNMP Agent
No specific CLI command exists to enable SNMP. The first snmp-server global configuration command
that you enter enables SNMPv1 and SNMPv2.
You can also enable SNMP on the SNMP Properties page on the web-browser interface. When you
enable SNMP on the web-browser interface, the access point automatically creates a community string
called public with read-only access to the IEEE802dot11 MIB.
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.

Feature Default Setting
SNMP agent Disabled
SNMP community strings No strings are configured by default. However,
when you enable SNMP using the web-browser
interface, the access point automatically creates
the public community with read-only access to the
IEEE802dot11 MIB.
SNMP trap receiver None configured
SNMP traps None enabled
