Configuring SNMP Library Extensions
Depending on your release, the SNMP Library Extensions feature allows you to perform the following
configurations.
Prerequisites
To use this feature, you must be running Cisco IOS Release 12.4(22)T or a later release.
SNMP Get and Set Operations
The SNMP Library Extensions feature extends the EEM applet action info and Tcl
sys_reqinfo_snmp commands to include functionality for SNMP get-one, get-next, getid and set-any operations.
SNMP Get Operation
The SNMP event manager performs the SNMP get operation to retrieve one or more variables for the managed
objects. Using the
action info type snmp oid get-type and action info type snmp getid commands, you can
configure the SNMP event manager to send an SNMP get request by specifying the variables to retrieve, and
the IP address of the agent.
For example, if you want to retrieve the variable with the OID value of 1.3.6.1.2.1.1.1, you should specify
the variable value, that is 1.3.6.1.2.1.1.1. If the specified values do not match, a trap will be generated and an
error message will be written to the syslog history.
The action info type snmp oid get-type command specifies the type of the get operation to be performed.
To retrieve the exact variable, the get operation type should be specified as
exact
. To retrieve a lexicographical
successor of the specified OID value, the get operation type should be set to
next
.
The table below shows the built-in variables, in which the values retrieved from SNMP get operation are
stored.
