limit (IGMP)
Function
The limit command sets the maximum number of IGMP entries that can be created globally.
The undo limit command restores the maximum number of IGMP entries that can be created globally to the default value.
By default, a maximum number of 256 IGMP entries can be created globally.
Parameters

| number | Specifies the maximum number of IGMP entries that can be created globally. | The value is an integer that ranges from 1 to 256. |
Usage Guidelines
Usage Scenario
This command sets the maximum number of IGMP entries globally.
When the number of IGMP entries reaches the limit, the system does not create any IGMP entries. To enable the wireless access controller to create more IGMP entries, delete useless entries or increase the limit. Alternatively, create static IGMP entries.
The number of IGMP entries is counted as follows:
Each (*, G) entry is counted as one entry.
Each (S, G) entry is counted as one entry.
Each (*, G) entry established with SSM mapping is counted as one entry.
Prerequisites
Multicast routing has been enabled using the multicast routing-enable command.
Precautions
You can also run the igmp global limit number command in the system view to set the maximum number of global IGMP group memberships. If both the limit and igmp global limit number commands are executed, the smaller value takes effect.
