Note that IGMP Snooping operates dynamically and with or without these static filter entries.
Note that vlan must be disabled before enabling any „bfilter‟s.
Example of the Filters bfilter screen:
CLI\SWITCH\FILTERS>bfilter
Enter ports that are to receive General Broadcast frames >
Use commas to separate port numbers. (Example: '3,6,12,14,22<enter>'.)
Enter Port Numbers (or ESC to exit):1,5,9,12,18,24,26
These ports receive General Broadcast now: 1 5 9 12 18 24 26
CLI\SWITCH\FILTERS>
Example of the Filters sfilter screen:
CLI\SWITCH\FILTERS>sfilter
Enter 1, 2, 3, ... ,16, or <(ESC)> >
Enter: <(ESC)> to cancel change and keep current configuration, or
static multicast filter number (1 ->16).
CLI> 1
Enter 12 digit Address (Ex. '01005e0a0a0a<enter>'),
or all zeroes to disable the group.
or [ESC] to Exit
CLI> 01005e010100
Enter ports that are to receive on this multicast address:
Use commas to separate port numbers. (Example: '3,6,12,14,22<enter>'.)
Enter Port Numbers (or ESC to exit):3,8,18,24,25
There is a total of 1 Static Filter Active.

Example of the Filters info screen:
CLI\SWITCH\FILTERS>info
These ports receive General Broadcast now: 1 5 9 12 18 24 26
There is a total of 1 Static Filter Active.

In the case above, ethernet frames coming into the switch at any port, with a destination address within the
frame of 01-00-5E-01-01-00 will go out of switch ports 3, 8, 18, 24, and 25, and only to those ports
(excluding the port received on). For example, an ethernet frame with that address could come into switch
port 1 and it would go out of switch ports 3, 8, 18, 24, and 25 only.
