cisgIpsSgGlobalHashValidFails
Module: CISCO-IPSEC-SIGNALING-MIB
OID (symbolic): CISCO-IPSEC-SIGNALING-MIB::cisgIpsSgGlobalHashValidFails
OID (numeric): 1.3.6.1.4.1.9.9.438.1.1.1.1.21
Node type: OBJECT-TYPE
Type: Counter64
Access: read-only
Description: The total number of hash validation operations in all current and previous Phase-1 Control Tunnels which resulted in failure.
What is cisgIpsSgGlobalHashValidFails?
This Counter64 totals hash validation operations across all current and previous Phase-1 control tunnels that resulted in failure, per its description - meaning a received IKE message's integrity check didn't match what was expected. It points to either data corruption in transit or a hash algorithm/key mismatch between peers, distinct from a decryption failure which is about confidentiality rather than integrity. An admin seeing this climb specifically on tunnels crossing a particular WAN path would suspect that specific network path is corrupting packets.
