configure interface cable-mac * isis hello-multiplier
Purpose
Configures the number of IS-IS hello packets a neighbor must miss before the router declares the neighbor to be down on the
specified interface.
Default Access Level
15
Command Syntax
configure interface cable-mac <mac[.s]> isis hello-multiplier <multiplier> [<level1 | level2>]
configure interface cable-mac <mac[.s]> isis hello-multiplier [<multiplier>] [<level1 | level2>] no
Supplemental
Information
This time determines how quickly a failed neighbor is detected so that routes can be recalculated.
The advertised hold time in IS-IS hello packets will be set to the hello multiplier times the hello interval. Neighbors will declare an
adjacency to this router down after not having received any IS-IS hello packets during the advertised hold time. The hold time can be
set on a per-interface basis and can be different between different routers in one area.
Note: Using a smaller hello multiplier will give fast convergence, but can result in more routing instability. Incrementing the hello
multiplier to a larger value will help stabilize the network. Never configure a hello multiplier lower than the default value of 3.
To restore the default value, use the no option.
Parameters
<mac[.s]>
The MAC identifier and optional sub interface.
<multiplier>
This is an integer value from 2 to 100. The advertised hold time in IS-IS hello packets will be set to the hello multiplier times the hello
interval. Neighbors will declare an adjacency to this router down after not having received any IS-IS hello packets during the
advertised hold time. The default value is 3
[<level1 | level2>]
Specifies the type of adjacencies to be formed on this interface. If no value is specified, then modify value for both level-1 and level-
2.
