5.7.2 VLAN Configurations of IGMP Snooping
If a VLAN is not IGMP snooping-enabled, it floods multicast data and control packets to the
entire VLAN in hardware. When snooping is enabled, IGMP packets are trapped to the CPU.
Data packets are mirrored to the CPU in addition to being VLAN flooded. The CPU then
installs hardware resources, so that subsequent data packets can be switched to desired ports
in hardware without going to the CPU.
Each page shows up to 99 entries from the VLAN table, depending on the value in the Entries
Per Page field. By default, the page will show the first 20 entries from the beginning of the
VLAN table. The first displayed will be the one with the lowest VLAN ID found in the VLAN
Table.
The
VLAN
