time: Specifies the inhibition time, which is in the range of 0 to 30 seconds.
Usage guidelines
An RB that acts as the AVF of a VLAN guarantees that frames from the VLAN have only one incoming
port or one outgoing port along a link. When other RBs receive frames from the VLAN, they do not
perform any processing. However, when the RB detects that a root bridge change occurs on a link or that
the AVF advertised by other RBs conflicts with the local AVF, the RB inhibits the local AVF for a certain
time to avoid loops. When the inhibition time expires, if the RB is still the AVF of the VLAN, the RB restores
the role of AVF.
Configuration in Layer 2 Ethernet interface view takes effect on only 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.
Examples
# Set the inhibition time to 20 seconds on port Ten-GigabitEthernet 1/0/1.
<Sysname> system-view
[Sysname] interface ten-gigabitethernet 1/0/1
[Sysname-Ten-GigabitEthernet1/0/1] trill timer avf-inhibited 20
trill timer csnp
Use trill timer csnp to configure the CSNP interval.
Use undo trill timer csnp to restore the default.
