isis hello padding

Re-enables Intermediate System-to-Intermediate System (IS-IS) hello padding at the interface level.

Syntax

isis hello padding [ disable ]

no isis hello padding [ disable ]

Command Default

IS-IS hello padding is enabled.

Parameters

disable: Disables hello padding on the interface.

Modes

Interface subtype configuration mode

Usage Guidelines

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

Generally, you do not need to disable padding unless a link is experiencing slow performance. If you enable or disable padding on an interface, the interface setting overrides the global setting configured using the hello padding command.

The no form of the command disables hello padding.

Examples

The following example re-enables IS-IS hello padding on an Ethernet interface.

device# configure terminal
device(config)# interface ethernet 1/1
device(config-if-eth-1/1)# isis hello padding
