Module: ZYXEL-VLAN-TRUNK-MIB

OID (symbolic): ZYXEL-VLAN-TRUNK-MIB::zyVlanTrunkPortState

OID (numeric): 1.3.6.1.4.1.890.1.15.3.90.1.1.1.1

Description: Enable/Disable VlanTrunking on the indicated port. Enable(1) to allow frames belonging to unknown VLAN groups to pass through the switch.

What is zyVlanTrunkPortState?

This value enables or disables VLAN trunking on a specific port; when enabled, the port is allowed to pass frames belonging to VLAN groups it doesn't explicitly recognize, rather than dropping them. Administrators enable this on uplink ports connecting to other switches so unrecognized-but-valid VLAN tags can still traverse the link transparently. For example, enabling trunking on an inter-switch uplink port would let traffic for a newly added VLAN pass through even before that specific VLAN is explicitly configured on this switch.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.890.1.15.3.90.1.1.1.1
snmpwalk -v2c -c public <target> ZYXEL-VLAN-TRUNK-MIB::zyVlanTrunkPortState

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.890.1.15.3.90.1.1.1.1.1
snmpget -v2c -c public <target> ZYXEL-VLAN-TRUNK-MIB::zyVlanTrunkPortState.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.890.1.15.3.90.1.1.1.1.1 s <value>
