LIMITED IP MULTICAST ADDRESS
The Limited IP Multicast Address commands allow users to specify which multicast address(es) reports are to be received on
specified ports on the switch. This function will therefore limit the number of reports received and the number of multicast groups
configured on the switch. The user may set an IP address or range of IP addresses to accept reports (Permit) or deny reports
(Deny) coming into the specified switch ports. The Limited IP Multicast Address 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>}
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.
<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 <multicast_ipaddr> - Enter the lowest multicast IP address of the
range.
access - Choose 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.
Parameters
to <multicast_ipaddr> - Enter the highest multicast IP address of the range.
Example usage:
To configure the limited multicast address on ports 1-3:
DGS-3400:4#config limited multicast address 1:1-1:3 from
224.1.1.1 to 224.1.1.2 access permit state enable
Command: config limited multicast address 1:1-1:3 from
224.1.1.1 to 224.1.1.2 access permit state enable
Success.
