show isis adjacency holddown

Syntax

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.
