What is juniIsisSysL2CircAuthenticationKeyType?

Read-write enumeration (none, plaintext, hmacMd5; default hmacMd5) selecting the authentication scheme for Level 2 hello packets, mirroring juniIsisSysL1CircAuthenticationKeyType at the backbone level.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.4874.2.2.38.1.2.3.1.5
snmpwalk -v2c -c public <target> Juniper-ISIS-MIB::juniIsisSysL2CircAuthenticationKeyType

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.4874.2.2.38.1.2.3.1.5.1
snmpget -v2c -c public <target> Juniper-ISIS-MIB::juniIsisSysL2CircAuthenticationKeyType.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.4874.2.2.38.1.2.3.1.5.1 i <value>
