Syntax

content_copy zoom_out_map
show isis adjacency holddown
<level>
<brief | detail | extensive>
<instance instance-name>
<logical-system (all | logical-system-name)>

Description

Display holddown status and time when IS-IS adjacencies are being formed. Adjacency holddown process takes place on an IS-IS level basis. When adjacency holdown is enabled, IS-IS adjacencies are formed sequentially. There is a holddown time between each adjacency and the process is completed when all IS-IS adjacencies are formed. This holddown time might cause network instability.

This command is useful to verify whether the adjacency holddown is enabled and facilitates troubleshooting when there are adjacency issues due to IS-IS adjacency holddown .

Options

none

Display standard overview information about IS-IS adjacency holddown for all routing instances.

brief | detail | extensive

(Optional) Display standard information about IS-IS adjacency holddown with the specified level of output.

instance instance-name

(Optional) Display IS-IS adjacency holddown information for the specified routing instance.

level

(Optional) Display information about IS-IS neighbors for the specified IS-IS level.

logical-system (all | logical-system-name)

(Optional) Perform this operation on all logical systems or on a particular logical system.
