NETGEAR 8800 Chassis Switch CLI Manual Description Enables or disables compression of entries in the IP multicast group table to facilitate improved IP multicast scaling. Syntax Description group-table off Enables compression. Disables compression. Default group-table Usage Guidelines Compression of IP multicast group table entries allows the switch to process more multicast traffic using the faster switch hardware instead of the relatively slower switch software. Compression requires additional processing. Disable this feature if you suspect a problem exposed by IP multicast compression. When you enable or disable this feature, all IP multicast entries are flushed, and this can result in a temporary loss of multicast traffic while the IP multicast entries are relearned. Note: On NETGEAR 8800 series switches, all IP multicast forwarding entries utilizing the same IP multicast group table entry share a single backplane link, limiting the total throughput to 12Gbps. To display the compression feature configuration, enter the command: show forwarding configuration Example The following command disables compression: configure forwarding ipmc compression off configure igmp configure igmp {} Description Configures the Internet Group Management Protocol (IGMP) timers. 1166 | Chapter 26.
