isis hello-padding

Use this command to configure IS-IS hello padding on an interface.

Syntax

isis hello-padding
no isis hello-padding

Parameters

None.

Defaults

None.

Mode

Interface configuration.

Usage

IS-IS hello packets by default are padded to the MTU size. Hello padding allows for early detection of errors that result from transmission problems with large frames or errors that result from mismatched MTUs on an interface.

Disabling hello padding lowers network bandwidth usage.

The “no” form of this command disables hello padding on the interface.

Example

This example shows how to disable hello padding on VLAN 100:

System(rw)->configure
System(rw-config)->interface vlan 100
System(rw-config-intf-vlan.0.100)->no isis hello-padding
System(rw-config-intf-vlan.0.100)->
