What is snSwDefaultVLanId?

This OID stores a number representing which virtual LAN (VLAN) is the default for untagged traffic on the switch. You can read and change this value to determine how network traffic is segregated by default. A network operator would modify this when reconfiguring the default network segment, such as when adding a new department to the switch.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1991.1.1.3.1.38
snmpwalk -v2c -c public <target> FOUNDRY-SN-SWITCH-GROUP-MIB::snSwDefaultVLanId

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.1991.1.1.3.1.38.1
snmpget -v2c -c public <target> FOUNDRY-SN-SWITCH-GROUP-MIB::snSwDefaultVLanId.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.1991.1.1.3.1.38.1 i <value>
