ceipSecTunHistInSaEncryptKeySize

Module: CISCO-ENHANCED-IPSEC-FLOW-MIB

OID (symbolic): CISCO-ENHANCED-IPSEC-FLOW-MIB::ceipSecTunHistInSaEncryptKeySize

OID (numeric): 1.3.6.1.4.1.9.9.432.1.2.2.1.20

Node type: OBJECT-TYPE

Type: CIPsecEncryptionKeySize

Access: read-only

Description: The size in bits of the key which was negotiated to be used with the encryption transform used with this tunnel denoted by ceipSecTunHistInSaEncryptAlgo.

For DES and 3DES the key size is respectively 56 and 168. For AES, this will denote the negotiated key size.

What is ceipSecTunHistInSaEncryptKeySize?

Reports the negotiated key size in bits used for the inbound encryption algorithm of this tunnel, such as 56 bits for DES or 168 bits for 3DES.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.9.432.1.2.2.1.20
snmpwalk -v2c -c public <target> CISCO-ENHANCED-IPSEC-FLOW-MIB::ceipSecTunHistInSaEncryptKeySize

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.9.9.432.1.2.2.1.20.1
