destroy igmp filter
Syntax DESTroy IGMP FILter=filter-id
where:
■ filter-id is a decimal number in the range 1 to 99.
Description This command destroys an IGMP filter and all entries in the filter. IGMP filters
control a port’s membership of multicast groups by filtering Membership
Reports received from hosts attached to the port.
The filter parameter specifies the number of the filter to destroy. A filter with
the specified number must already exist.
You should remove the filter from any ports before you destroy the filter. Use
the show switch port command to see which ports the filter is applied to, and
the set igmp filter command to remove the filter from any ports.
Examples To destroy filter 6, use the command:
des igmp fil=6
set igmp filter
Syntax SET IGMP FILter=filter-id ENTry=1..65535
[GROupaddress=ipadd[-ipadd]] [ACtion={INCLude|EXCLude}]
where:
■ filter-id is a decimal number in the range 1 to 99.
■ ipadd is an IP address in dotted decimal notation.
Description This command modifies an entry in an IGMP filter. IGMP filters control a
port’s membership of multicast groups by filtering Membership Reports
received from hosts attached to the port.
The filter parameter specifies the number of the filter that the entry belongs to.
A filter with the specified number must already exist.
The entry parameter specifies the entry to modify. An entry with the specified
number must already exist.
The groupaddress parameter specifies an IP multicast group address, or a
range of IP multicast group addresses to match. The IP addresses must be
multicast addresses.
The action parameter specifies the action to take when an IGMP Membership
Report group address matches the value of groupaddress. If you specify
include, Membership Reports matching groupaddress are processed as normal
by IGMP. If you specify exclude, Membership Reports matching groupaddress
are excluding from processing by IGMP, and the packets are discarded. The
default is include.
