isis hello-multiplier

Specifies the number of Intermediate System-to-Intermediate System (IS-IS) hello packets a neighbor must miss before the device declares adjacency as down.

Syntax

isis hello-multiplier { level-1 | level-2 } multiplier

no isis multiplier { level-1 | level-2 } multiplier

Command Default

The default is 3.

Parameters

level-1: Configures the hello multiplier for Level 1 adjacencies.
level-2: Configures the hello multiplier for Level 2 adjacencies.
multiplier: Specifies the multiplier. Valid values range from 3 through 1000. The default is 3.

Modes

Interface subtype configuration mode

Usage Guidelines

IS-IS is supported on the Extreme 8820, SLX 9740, SLX 9640, and SLX 9540 devices only.

The hello multiplier is the number by which an IS-IS interface multiplies the hello interval to obtain the hold time for Level-1 and Level-2 IS-IS hello PDUs.

The no form of the command restores the default of 10 seconds.

Examples

The following example changes the hello multiplier for Level 1 packets for an Ethernet interface.

device# configure terminal
device(config)# interface ethernet 1/1
device(conf-if-eth-1/1)# isis hello-multiplier level-1 10

The following example changes the hello multiplier for Level 2 packets for a loopback interface.

device# configure terminal
device(config)# interface loopback 1
device(config-Loopback-1)# isis hello-mulitplier level-2 20
