Showing IGMP Information (asg_igmp)
Use this command to show IGMP information in a tabular format. You can filter the output for specified interfaces and SGMs. If no blade is specified, the command runs a verification to make sure that IGMP data is the same on all SGMs:
- Group verification - Makes sure that the groups exist on all SGMs. If a group is missing on some SGMs, a message shows which group is missing on which blade.
- Global properties - Makes sure that the flags, address and other information are identical on all SGMs.
- Interfaces - Makes sure that all blade have the same interfaces and that they are in the same state (Up or Down). If inconsistencies are detected, a warning message shows.
Syntax
asg_igmp -h
asg_igmp [-i <interface>] [-b <sgm_ids>]
Parameter
|
Description
|
-h
|
Show command syntax.
|
-i
|
Source interface name.
|
-b <sgm_ids>
|
Works with SGMs and/or Chassis as specified by <sgm_ids>.
The <sgm_ids> can be:
- No <sgm
_ids> specified or all shows all SGMs and Chassis - One SGM
- A comma-separated list of SGMs (
1_1,1_4) - A range of SGMs (
1_1-1_4) - One Chassis (
Chassis1 or Chassis2) - The active Chassis (
chassis_active)
|
Example: Show IGMP information for all interfaces and SGMs
This example shows IGMP information and multicast routes for all interfaces and SGMs. In this example, the verification detected an interface inconsistency.
