Parameters

time: Specifies the AVF inhibition time in the range of 0 to 30 seconds.

Usage guidelines

The AVF of a VLAN guarantees that frames of the VLAN enter and leave a broadcast network through the same port. Other RBs on the broadcast network do not process frames from the VLAN.

To avoid loops, the RB that acts as the AVF suppresses its AVF role during the inhibition time when one of the following conditions exists:

• The RB detects a root bridge change on the broadcast network.

• Other RBs advertise a different AVF for the VLAN.

When the inhibition time expires, the RB restores its AVF role if it is still the AVF of the VLAN. Configuration in Layer 2 Ethernet interface view takes effect only on the current port. Configuration in Layer 2 aggregate interface view takes effect on the current interface and its member ports. Configuration on the member port of an aggregate interface takes effect after the member port leaves the aggregation group.
