hello padding

Re-enables the padding of Intermediate System-to-Intermediate System (IS-IS) hello Protocol Data Units (PDUs) globally.

Syntax

hello padding [ disable ] [ point-to-point ]

no hello padding [ disable ] [ point-to-point ]

Command Default

Enabled.

Parameters

disable: Disables the padding of IS-IS hello PDUs.
point-to-point: Specifies point-to-point interfaces.

Modes

IS-IS router configuration mode

Usage Guidelines

IS-IS is 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 using the isis hello padding command, the interface setting overrides the global setting.

The no form of the command disables the padding of IS-IS hello PDUs.
