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.
Command Modes
Normal.
Usage Guidelines
The switch dynamically chooses either IGMP-only or IGMP and CGMP mode, depending on the traffic present on the network. IGMP-only mode is used in networks with no CGMP devices. IGMP and 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 diplay the IGMP mode:
IGMP Operational Mode: igmp-only
IGMP Address Aliasing Mode: normal
Usage Guidelines
set igmp mode
