cifIkeTunHistDHGrp
Module: CISCO-IKE-FLOW-MIB
OID (symbolic): CISCO-IKE-FLOW-MIB::cifIkeTunHistDHGrp
OID (numeric): 1.3.6.1.4.1.9.9.429.1.2.1.1.2
Node type: OBJECT-TYPE
Type: CIPsecDiffHellmanGrp
Access: read-only
Description: The Diffie Hellman Group used in Phase-1 IKE negotiations.
What is cifIkeTunHistDHGrp?
This preserves the Diffie-Hellman group used by a now-expired Phase-1 tunnel, per its description, sitting alongside cifIkeTunHistNegoMode in the same history table. It's the forensic counterpart to the live cifIkeTunDHGrp object, letting an admin audit the cryptographic strength a since-closed connection actually used. A history entry showing group1 (768-bit) for a tunnel to an old partner site is concrete evidence to tighten that partner's policy going forward.
