show igmp mode

Use the show igmp mode command to display the igmp mode on the switch.

show igmp mode

Syntax Description

This command has no keywords or arguments.

Defaults

This command has no default settings.

Command Types

Switch.

Command Modes

Normal.

Usage Guidelines

The switch dynamically chooses either IGMP-only or IGMP/CGMP mode, depending on the traffic present on the network. IGMP-only mode is used in networks with no CGMP devices. IGMP/CGMP mode is used in networks with both IGMP and CGMP devices.

The show igmp mode command output includes three fields:

•IGMP Mode—Possible values are auto, igmp-only, and igmp-cgmp.

•IGMP-Operational-Mode—Possible values are igmp-only and igmp-cgmp.

•IGMP Address Aliasing Mode—Possible values are normal and fallback.

Examples

This example shows how to display the igmp mode:

Console> show igmp mode

IGMP Mode:                  auto

IGMP Operational Mode:      igmp-only

IGMP Address Aliasing Mode: normal
