Configuring SNMP and Trap Message Parameters

The access point  SNMP agent must be enabled to function (for versions 1, 2c, and 
3 clients). Management access using SNMP v1 and v2c also requires community 
strings to be configured for authentication. Trap notifications can be enabled and 
sent to up to four management stations.

SNMP

 – Enables or disables SNMP management access and also enables the 

access point to send SNMP traps (notifications). (Default: Disable)

Location

 – A text string that describes the system location. (Maximum length: 255 

characters)

Contact

 – A text string that describes the system contact. (Maximum length: 255 

characters)

Community Name (Read Only)

 – Defines the SNMP community access string that 

has read-only access. Authorized management stations are only able to retrieve 
MIB objects. (Maximum length: 23 characters, case sensitive; Default: public)
