Usage Guidelines

This command applies only to Summit family switches and BlackDiamond 8800 series switches.

Use the per-vlan option when the number of VLANs configured on the switch is lower than the maximum numbers listed in the following table. This option conserves usage of the hardware Layer 3 multicast forwarding table.

When the number of configured VLANs is larger than the maximum values listed here, select the per-port option. Each VLAN requires additional interface hardware ACL resources. The per-port option conserves usage of the interface hardware ACL resources.

c Series 2,000
e Series 448

The actual maximum value is smaller if other processes require entries in the interface ACL table. To display the IGMP snooping filters configuration, use the show igmp snooping command.



For MLD Snooping, the maximum number of VLANs is half of the numbers provided in this table. The maximum number specified here is individual limit for IGMP snooping filters. If both IGMP and MLD snooping filters are used, the maximum numbers are lower than the ones specified.
