LinkUp/Down Traps Support (RFC 2233)

The objects in the varbind list, based on the Internet Engineering Task Force (IETF) standard, are defined
in IF-MIB. Since IF-MIB supports subinterfaces, all objects in this varbind list are also supported for
subinterfaces. The feature allows you to base the Link Up/Down trap varbind list on a Cisco-specific or
IETF standard with a new CLI configuration command.
To enable linkUp/linkDown Simple Network Management Protocol (SNMP) traps which are compliant
with RFC2233, use the snmp-server trap link command in global configuration mode. To disable IETF
compliant functionality and revert to the default Cisco implementation of linkUp/linkDown traps, use
the no form of this command.

Increase the SNMP trap queue size. The default queue size is 10, which is insufficient to handle all traps.
Use the snmp-server queue-length length global configuration command to increase the queue size. The
length parameter can range from 10 to 1000. Increase the queue size until traps are no longer dropped.
Disable unneeded SNMP traps. For example, if you do not need SYSLOG traps (which are sent for
every message displayed on the console), disable those traps as follows:
Router(config)# snmp-server enable traps
Router(config)# no snmp-server enable traps syslog

The default is a Cisco-specific link trap (snmp-server link-trap cisco). The user can
switch between Cisco and IETF standard.
This keyword links functionality of SNMP linkUp/linkDown traps to the Internet
Engineering Task Force (IETF) standard (as opposed to the previous Cisco
implementation).
