Usage Guidelines

This command is used to configure the maximum number of IGMP entries for a single instance.

When the number of IGMP entries reaches the limit, the system does not create any IGMP entry. To make the FW to allow more new join requests, delete some useless entries or modify the limit. Alternatively, you can enable static addition to a multicast group or source/group.

The methods of counting the number of IGMP entries are as follows:

Each (*, G) entry is counted as one IGMP entry.
Each (S, G) entry is counted as one IGMP entry.
Each (*, G) entry for Source-Specific Multicast (SSM) mapping is counted as one IGMP entry.

Example

# Set the maximum number of IGMP entries that can be created in the public network instance to 1024.

<sysname> system-view
[sysname] igmp
[sysname-igmp] limit 1024
