UDLR

UDLR enables a router to emulate the behavior of a bidirectional link for IP operations over two unidirectional links.

The feature is normally used for asymmetric links (such as in video transport networks) where the downstream link

requires a much higher bandwidth than the upstream link.

Enhanced SNMP MIB Support

Additional SNMP MIBs are supported in this release. They are:

• CISCO-IF-EXTENSION-MIB

• ETHERLIKE-MIB

Cisco IOS Software Release 12.1(19)EW follows the standard Cisco support policy, which is available at:
