ctDot1qVlanDynamicEgressStatus
Module: CTRON-Q-BRIDGE-MIB-EXT
OID (symbolic): CTRON-Q-BRIDGE-MIB-EXT::ctDot1qVlanDynamicEgressStatus
OID (numeric): 1.3.6.1.4.1.52.4.1.2.16.7.1.2.1.2
Node type: OBJECT-TYPE
Type: EnabledStatus
Access: read-write
Description: The state of Dynamic Egress operation on this VLAN. The value enabled(1) indicates that Dynamic Egress is enabled on this VLAN. If Dynamic Egress is enabled for a VLAN the following rules are applied to received frames:
1. If the frame is untagged, and
2. The frame is successfully classified to the specified VLAN, and
3. The port the frame was received on is not configured in dot1qVlanCurrentEgressPorts, dot1qVlanCurrentUntaggedPorts, or dot1qVlanForbiddenEgressPorts, for the classified VLAN, and
4. The port is configured for forwardNoFrames(1) in ctDot1qPortDefaultForwardMode (if supported), then
5. The port the frame was received on will be added to the dot1qVlanCurrentEgressPorts and dot1qVlanCurrentUntaggedPorts for the classified VLAN. If the VLAN was not preexisting the dot1qVlanStatus leaf for the VLAN will return other(1).
What is ctDot1qVlanDynamicEgressStatus?
This value enables or disables Dynamic Egress on a specific VLAN, a feature that automatically adds a receiving port to that VLAN's current egress and untagged port lists when an untagged frame classified to the VLAN arrives on a port not already forbidden or listed for it and configured for forwardNoFrames. An admin enables it so ports can automatically join a VLAN's forwarding set the first time they see legitimate untagged traffic for it, instead of requiring manual static configuration on every port. For example, enabling Dynamic Egress on VLAN 50 lets a previously unconfigured port automatically start egressing VLAN 50 traffic untagged the moment it receives a frame classified into that VLAN.
