What is swNbIslCost?

Reports (and lets an admin override) the FSPF routing cost assigned to this ISL, which influences which path traffic takes across a multi-switch fabric. Raising the cost on a link is a common way to de-prioritize a slower or backup path in favor of a faster primary route.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1588.2.1.1.1.2.9.1.7
snmpwalk -v2c -c public <target> SW-MIB::swNbIslCost

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.1588.2.1.1.1.2.9.1.7.1
snmpget -v2c -c public <target> SW-MIB::swNbIslCost.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.1588.2.1.1.1.2.9.1.7.1 i <value>
