The igmp global limit command sets the maximum number of IGMP entries that can be created on the switch.
The undo igmp global limit command deletes the configured maximum number of IGMP entries.
| Parameter | Description | Value |
|---|---|---|
number |
Specifies the maximum number of IGMP entries that can be created on the switch. |
The value is an integer that ranges from 1 to The maximum number of IGMP entries allowed by default. NOTE:
The value range of S5720-HI, S5730-HI, S5731-H, S5731S-H, S5732-H, S6720-HI, S6730S-H, and S6730-H are expanded after the high specification mode is configured for multicast forwarding using the set multicast forwarding-table super-mode command. The actual value range depends on the specification of the device. |
Usage Scenario
When the number of IGMP entries reaches the limit, the system does not create any new IGMP entries. To enable the switch to create new IGMP entries, delete unnecessary entries or increase the limit. Alternatively, you can configure static IGMP entries or source-groups.
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.
Precautions
You can also run the limit (IGMP view) command in the IGMP view to set the maximum number of IGMP group memberships in the system. If both the igmp global limit and limit (IGMP view) commands are run, the smaller value takes effect.
