Creating Multicast VLANs
Page 23-7
Step C. Defining the Recipients of Multicast Traffic
You can define the recipients of multicast traffic by virtual port or MAC address. You define
these recipients as policies for this multicast VLAN . The available policies for recipients are
Port and MAC Address. You can use both rules within a single multicast VLAN . For example,
you might want to flood multicast traffic to all devices attached to one switch port, but only a
few devices attached to other switch ports. In this case, you could use a Port rule for the
devices on the port where all devices receive the multicast traffic, and then the
MAC address
rule to flood multicast traffic only to specific devices attached to the other ports on the switch.
Follow the directions in one of the following sections for the rule type you want to define.
Defining Recipients By Port
After you define the multicast address, the following menu displays:
Select rule type:
1. Port Rule
2. MAC Address Rule
3. Multicast Address Rule
Enter rule type (1):
1. Press <Return> .
2. The following prompt displays:
Set Rule Admin Status to ((e)nable/(d)isable):
Indicate whether or not you want to enable this rule. Type e to enable or d to disable. If
you enable the rule, the multicast VLAN will use it to determine membership of devices. If
you disable the rule, then this rule will not be used in assigning devices to this multicast
VLAN , but the parameters you set up for the multicast VLAN will be saved. This Admin
Status is different from the Admin Status for the multicast VLAN as it controls only this
specific rule within this specific multicast VLAN . You can enable or disable the rule at a
later time using the modmcvl command.
3. The following prompt displays:
Enter the list of port in Slot/Int/Service/Instance format:
Enter the ports that you want to receive multicast traffic for this multicast VLAN . You may
enter multiple ports at a time. You can include a total of 255 ports per switch in a port-
based multicast
VLAN . Use the <slot>/<port> format. For example, to include port 7 from
the module in slot 2, you would enter 2/7. (The service and instance numbers are not
necessary for specifying physical ports. They are only necessary when specifying logical
or virtual ports, which normally only differ from physical ports in more complex configu-
rations, such as
ATM LAN Emulation.)
4. The following prompt displays:
Configure more rules for this vlan (y/n):
You can set up multiple rules for the same multicast VLAN . Enter a Y here if you want to
set up more rules in addition to the port rule specified here. If you enter Y , you will be
prompted for the next rule that you want to set up on this multicast VLAN . If you enter N ,
you will receive a message, similar to the one below, indicating that the multicast VLAN
was set up.
VLAN 3:23 created successfully
5. If you are done setting up rules for this multicast VLAN , then your multicast VLAN is set
up. You can monitor activity on these multicast VLAN s through other AutoTracker
commands. See later sections in this chapter for information on these commands.
