What is isisSysMaxAge?

Sets the initial remaining-lifetime value the router stamps on LSPs it generates, in seconds; should be set at least 300 seconds greater than isisSysMaxLSPGenInt so an LSP doesn't expire before it's due to be refreshed.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.138.1.1.1.10
snmpwalk -v2c -c public <target> ISIS-MIB::isisSysMaxAge

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.138.1.1.1.10.1
snmpget -v2c -c public <target> ISIS-MIB::isisSysMaxAge.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.2.1.138.1.1.1.10.1 i <value>
