isisSysMaxLSPGenInt

Module: ISIS-MIB

OID (symbolic): ISIS-MIB::isisSysMaxLSPGenInt

OID (numeric): 1.3.6.1.2.1.138.1.1.1.5

Node type: OBJECT-TYPE

Type: Unsigned32

Access: read-write

Description: Maximum interval, in seconds, between generated LSPs by this Intermediate System. This object follows the ResettingTimer behavior. The value must be greater than any value configured for isisSysLevelMinLSPGenInt, and should be at least 300 seconds less than isisSysMaxAge.

Configured values MUST survive an agent reboot.

What is isisSysMaxLSPGenInt?

Sets the maximum interval, in seconds, between the router regenerating its own Link State PDUs. Must be smaller than isisSysMaxAge (with roughly 300 seconds of margin) so LSPs get refreshed well before they'd otherwise expire.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.138.1.1.1.5
snmpwalk -v2c -c public <target> ISIS-MIB::isisSysMaxLSPGenInt

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.138.1.1.1.5.1
snmpget -v2c -c public <target> ISIS-MIB::isisSysMaxLSPGenInt.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.2.1.138.1.1.1.5.1 i <value>
