DCS-3950 series Ethernet switch manual
destination control, the switch will not broadcast the multicast data it receives. So, we
should avoid connecting two or more other 3-layer switches to a switch with destination
control enabled within one VLAN.The following is the command to configure:
Command Explantation
Global configuration mode
[no] ip multicast
destination-control(necessary)
Enable the destination globally. The’ no ip
multicast destination-contro’ command will
disable the destination control globally.Only
after the desination control is enabled
globally, all of the other configurations can
take effect.
The next step is to configure the destination control rules, which is also similar to that
ofsource control except that it uses ACL ID from 6000 to 7999.
Command Explantation
Global configuration mode
[no] access-list <6000-7999>
{deny|permit} ip {{<source>
<source-wildcard>}|{host-source
<source-host-ip>}|any-source}
{{<destination>
<destination-wildcard>}|{host-des
tination
<destination-host-ip>}|any-destin
ation}
Configure the rule used in destination control.
The rule can only take effect when applied to
specified source IP or VLAN-MAC and port.
Prefixing the command with ‘NO’ can delete
the specified rule.
The last step is to configure the rule to specified source IP, source VLAN MAC or
port.What calls for attention is that, taking the above statement, only after enabling
IGMP-SNOOPING can we use the rules globally, if not, only source IP rules can be used
in IGMP protocol. If we configure source IP,VLAN MAC and specified port rules, the rules
are matched to messages in a sequence as VLAN MAC, sourve IP, specified ports. The
folloing is the command to configure:
Command Explantation
Port configuration mode
[no] ip multicast
destination-control access-group
<6000-7999>
To configure the rule used in source control to
a port, prefixing the command with ‘NO’ will
cancel the configuration.
Global configuration mode
[no] ip multicast
destination-control <1-4094>
<macaddr> access-group
<6000-7999>
To configure the rule used in source control to
specified VLAN-MAC, prefixing the command
with ‘NO’ will cancel the configuration.
[no] ip multicast
destination-control <source>
<source-wildcard> access-group
<6000-7999>
To configure the rule used in source control to
specified source IP address/MASK, prefixing
the command with ‘NO’ will cancel the
configuration.
