Description: The EIGRP authentication mode of the interface. none : no authentication enabled on the interface md5 : MD5 authentication enabled on the interface
What is cEigrpAuthMode?
This reports which EIGRP authentication mode, none or MD5, is currently configured on the interface. Since EIGRP neighbors will not form an adjacency unless their authentication mode and key match, this object is the first thing to check when two routers that should be peers show no cEigrpPeerCount at all. A branch router migrated to md5(2) while its hub still runs none(1) will simply fail to form the adjacency at all, with no obvious error beyond a missing peer.
Examples
Walk all instances (SNMPv2c):
