a3ComNextAvailableVirtIfIndex
Module: GENERIC-3COM-VLAN-MIB-1-0-7
OID (symbolic): GENERIC-3COM-VLAN-MIB-1-0-7::a3ComNextAvailableVirtIfIndex
OID (numeric): 1.3.6.1.4.1.43.10.1.14.3.1
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: The value of the next available virtual ifIndex. This object is used by an NMS to select an index value for row-creation in tables indexed by ifIndex. The current value of this object is changed to a new value when the current value is written to an agent's table, that is indexed by ifIndex. Row creation using the current value of this object, allocates a virtual ifIndex. Note the following:
1. A newly created row does not have to be active(1) for the agent to allocate the virtual ifIndex.
2. Race conditions between multiple NMS's end when a row is created. Rows are deemed created when a setRequest is successfully committed (i.e. the errorStats is noError(0)).
3. An agent that exhausts its supply of virual ifIndex values returns zero as the value of this object. This can be used by an NMS as an indication to deleted unused rows and reboot the device.
What is a3ComNextAvailableVirtIfIndex?
This read-only INTEGER reports the next available virtual ifIndex value that an NMS must use when creating a new row in a table indexed by ifIndex, such as a3ComVlanIfTable or a3ComVlanEncapsIfTable. An admin or NMS reads this value immediately before row creation, since using an index value that doesn't match the current returned value will cause the row creation to fail. Reading a value of 5003 tells the NMS to use ifIndex 5003 when creating the next new VLAN or encapsulation interface row.
