Description: A list of port indices which are the port membership of a VLAN By Port. Each port index is a 16-bit integer in big endian order. 8-bit is the slot number, the other 8-bit is the port number.

What is snVLanByPortPortList?

This object contains a bitmap representing which ports on the switch are members of a specific VLAN when using port-based VLAN membership. Each port is encoded as a 16-bit value where the high 8 bits represent the slot number and the low 8 bits represent the port number. Switch administrators use this to manage VLAN membership across switch modules and configure which ports can communicate with each other at the data-link layer.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1991.1.1.3.2.1.1.28
snmpwalk -v2c -c public <target> FOUNDRY-SN-SWITCH-GROUP-MIB::snVLanByPortPortList

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.1991.1.1.3.2.1.1.28.1
snmpget -v2c -c public <target> FOUNDRY-SN-SWITCH-GROUP-MIB::snVLanByPortPortList.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.1991.1.1.3.2.1.1.28.1 s <value>
