112 CLI Reference Guide for Directors and Edge Switches
Syntax
rerouteDelay rerouteDelayState
Purpose
This command enables or disables rerouting delay for the switch.
Description
The switch can be either offline or online when this command is executed.
This command is only applicable if the configured switch is in a multiswitch
fabric. Enabling the rerouting delay ensures that frames are delivered in order
through the fabric to their destination.
If there is a change to the fabric topology that creates a new path (for example, a
new switch is added to the fabric), frames may be routed over this new path if its
hop count is less than a previous path with a minimum hop count. This may result
in frames being delivered to a destination out of order because frames sent over
the new, shorter path may arrive ahead of older frames still in route over the older
path.
If rerouting delay is enabled, traffic ceases in the fabric for the time specified in
the config.switch.edTOV command. This delay allows frames sent on the
old path to exit to their destination before new frames begin traversing the new
path. Note that during this delay period, frames addressed to the destinations that
are being rerouted are discarded if they are Class 3 frames and rejected if they are
Class 2 or Class F frames.
Parameter
This command has one parameter:
config.switch.rerouteDelay
rerouteDelayState Specifies whether rerouting delay is enabled.
Valid values are true and false.
Boolean 1 and 0 may be substituted as
values.
