ipsecTunHistTermReason

Module: IPsecT1-MIB

OID (symbolic): IPsecT1-MIB::ipsecTunHistTermReason

OID (numeric): 1.3.6.1.4.1.2.6.168.1.1.1.1.4.3.1.1.2

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: The reason the ipsec Phase-2 Tunnel was terminated. Possible reasons include: 1 = other 2 = normal termination 3 = operator request 4 = peer delete request was received 5 = contact with peer was lost 6 = local failure occurred 7 = sequence number rolled over.

What is ipsecTunHistTermReason?

Why this Phase-2 tunnel ended: other (1), normal (2), operRequest (3), peerDelRequest (4), peerLost (5) or seqNumRollOver (6) per the defined values. The source text lists 6 as local failure and 7 as sequence rollover, which does not match the defined enum (6 is seqNumRollOver and 7 does not exist), so treat 6 with caution. Many peerLost (5) records for one site suggest connectivity trouble toward it.
