tunnelIfSecurity
Module: TUNNEL-MIB
OID (symbolic): TUNNEL-MIB::tunnelIfSecurity
OID (numeric): 1.3.6.1.2.1.10.131.1.1.1.1.5
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: The method used by the tunnel to secure the outer IP header. The value ipsec indicates that IPsec is used between the tunnel endpoints for authentication or encryption or both. More specific security-related information may be available in a MIB module for the security protocol in use.
What is tunnelIfSecurity?
This read-only value reports the method used to secure this tunnel's outer IP header: none(1) means no security, ipsec(2) means IPsec is used for authentication and/or encryption between the tunnel endpoints, and other(3) covers any other mechanism. Admins check it to confirm whether a given tunnel's traffic is actually being protected in transit, with more detailed IPsec-specific data available in a separate IPsec MIB module. For example, seeing none(1) on a tunnel carrying sensitive traffic across an untrusted network would flag that tunnel as needing IPsec protection to be added.
