LIMITED IP MULTICAST ADDRESS
The Limited IP Multicast command allows the administrator to permit or deny access to a port or range of ports by specifying a range
of multicast addresses. The Limited IP Multicast Commands in the Command Line Interface (CLI) are listed (along with the
appropriate parameters) in the following table.
Command Parameters
config limited multicast address <portlist> {from <multicast_ipaddr> to <multicast_ipaddr>
access [permit | deny] | state [enable | disable]}
delete limited multicast address [all | <portlist>]
show limited multicast address {<portlist>}
create multicast_range <range_name 32> from <multicast_ipaddr> to <multicast_ipaddr>
delete multicast_range [<range_name 32> | all]
show multicast_range {<range_name 32>}
config limited_multicast_addr ports <portlist> {add multicast_range <range_name 32> | delete
multicast_range [<range_name 32> | all] | {access [permit | deny] |
state [enable | disable]}]
show limited_multicast_addr {ports <portlist>}
Each command is listed in detail in the following sections.
config limited multicast address
Purpose Used to configure limited IP multicast address range.
Syntax
config limited multicast address <portlist> {from
<multicast_ipaddr> to <multicast_ipaddr> access [permit | deny] |
state [enable | disable]}
Description The config limited multicast address command allows the user to
configure the multicast address range, access level, and state.
Parameters <portlist> - A port or range of ports to config the limited multicast
address. The port list is specified by listing the lowest switch number
and the beginning port number on that switch, separated by a colon.
Then the highest switch number, and the highest port number of the
range (also separated by a colon) are specified. The beginning and end
of the port list range are separated by a dash. For example, 1:3
specifies switch number 1, port 3. 2:4 specifies switch number 2, port 4.
1:3-2:4 specifies all of the ports between switch 1, port 3 and switch 2,
port 4 − in numerical order. Non-contiguous portlist entries are
separated by a comma. (ex: 1:1-1:3,1:7-1:9)
from - Enter the lowest multicast IP address of the range.
to - Enter the highest multicast IP address of the range.
access - Use the access field to either permit or deny to limit or grant
access to a specified range of Multicast addresses on a particular port
or range of ports.
state - This parameter allows the user to enable or disable the limited
multicast address range on a specific port or range of ports.
Restrictions Only administrator-level users can issue this command. This command
is used as a backwards compatible command for legacy devices and
firmware.
