dot1qNextFreeLocalVlanIndex
Module: Q-BRIDGE-MIB
OID (symbolic): Q-BRIDGE-MIB::dot1qNextFreeLocalVlanIndex
OID (numeric): 1.3.6.1.2.1.17.7.1.4.4
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description:
The next available value for dot1qVlanIndex of a local VLAN entry in dot1qVlanStaticTable. This will report values >=4096 if a new Local VLAN may be created or else the value 0 if this is not possible.
A row creation operation in this table for an entry with a local VlanIndex value may fail if the current value of this object is not used as the index. Even if the value read is used, there is no guarantee that it will still be the valid index when the create operation is attempted; another manager may have already got in during the intervening time interval. In this case, dot1qNextFreeLocalVlanIndex should be re-read
and the creation re-tried with the new value.
This value will automatically change when the current value is used to create a new row.
What is dot1qNextFreeLocalVlanIndex?
This is a number showing the next available VLAN ID that can be created locally (4096 or higher), or 0 if no IDs remain. Network engineers check this before creating new VLANs to understand if the switch has available VLAN slots. If the value is 0, VLAN creation has reached the device limit and you must delete older VLANs first.
