What is isisSysVersion?

Reports which version of the IS-IS protocol this router instance implements, currently always one(1) (unknown(0) exists only as a placeholder for an undetected version). An admin or management station reads this to confirm protocol-version compatibility before assuming other IS-IS MIB objects behave as the current spec describes.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.2.826.0.1.1578918.5.63.1.1.1.1.1.2
snmpwalk -v2c -c public <target> DC-ISIS-MIB::isisSysVersion

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.2.826.0.1.1578918.5.63.1.1.1.1.1.2.1
snmpget -v2c -c public <target> DC-ISIS-MIB::isisSysVersion.1

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> isisSysVersion.1
