swIfDefaultTag
Module: CISCOSB-rlInterfaces
OID (symbolic): CISCOSB-rlInterfaces::swIfDefaultTag
OID (numeric): 1.3.6.1.4.1.9.6.1.101.43.1.1.11
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: This variable specifies the default VLAN tag which will be attached to outgoing frames if swIfTaggedMode for this interface is enabled.
What is swIfDefaultTag?
This read-only INTEGER (0-4095) reports the default VLAN tag attached to outgoing frames on this interface when swIfTaggedMode is enabled. It matters because it determines which VLAN untagged-origin traffic effectively gets associated with once tagging is turned on for that port. For example, if traffic from a device seems to land on VLAN 10 instead of the expected VLAN 20 after enabling tagged mode, checking this default tag value would explain the discrepancy.
