vRtrIsisLevelLoopfreeAltExclude

Module: TIMETRA-ISIS-MIB

OID (symbolic): TIMETRA-ISIS-MIB::vRtrIsisLevelLoopfreeAltExclude

OID (numeric): 1.3.6.1.4.1.6527.3.1.2.10.1.2.1.15

Node type: OBJECT-TYPE

Type: TruthValue

Access: read-write

Description: The value of vRtrIsisLevelLoopfreeAltExclude specifies whether or not the ISIS level should be excluded during LFA calculations. If the value is 'true', the ISIS level is excluded from LFA calculations. If the value is 'false', the ISIS level is included in LFA calculations.

The value of vRtrIsisLevelLoopfreeAltExclude is only valid when vRtrIsisLoopfreeAlternate has a value of 'true'.

What is vRtrIsisLevelLoopfreeAltExclude?

When true, excludes this entire IS-IS level from Loop-Free Alternate (LFA) backup-path calculations; this setting only has an effect when vRtrIsisLoopfreeAlternate is enabled, letting an admin turn off fast-reroute for one level (e.g. L2) while keeping it active on the other.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.6527.3.1.2.10.1.2.1.15
snmpwalk -v2c -c public <target> TIMETRA-ISIS-MIB::vRtrIsisLevelLoopfreeAltExclude

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.6527.3.1.2.10.1.2.1.15.1
snmpget -v2c -c public <target> TIMETRA-ISIS-MIB::vRtrIsisLevelLoopfreeAltExclude.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.6527.3.1.2.10.1.2.1.15.1 s <value>
