ospfIfAuthKey

Module: RFC1248-MIB

OID (symbolic): RFC1248-MIB::ospfIfAuthKey

OID (numeric): 1.3.6.1.2.1.13.7.1.16

Node type: OBJECT-TYPE

Type: OCTET STRING

Access: read-write

Description: The Authentication Key. If the Area's Authorization Type is simplePassword, and the key length is shorter than 8 octets, the agent will left adjust and zero fill to 8 octets.

When read, ospfIfAuthKey always returns an Octet String of length zero.

What is ospfIfAuthKey?

This holds the OSPF authentication key for this interface, used when the area's authentication type is simplePassword (short keys get left-adjusted and zero-filled to 8 octets); for security it always reads back as a zero-length string regardless of what was configured. Admins write this to set the shared password routers on this segment must present, then rely on ospfIfState/ospfNbrState to confirm adjacencies still form correctly afterward.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.13.7.1.16
snmpwalk -v2c -c public <target> RFC1248-MIB::ospfIfAuthKey

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.13.7.1.16.1
snmpget -v2c -c public <target> RFC1248-MIB::ospfIfAuthKey.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.2.1.13.7.1.16.1 s <value>
