Modifying Multicast VLANs

After you set up a multicast VLAN you can modify its Admin Status, description, rules, and the
Admin Status of each of the rules. You use the modmcvl command to modify a multicast VLAN
as follows:
modmcvl <Group Number>:<VLAN Number>
You must specify the Group and multicast VLAN number and they must be separated by a
colon. For example, to modify multicast VLAN 2 in Group 2, you would specify:
modmcvl 2:2
After entering a valid modmcvl command, a screen similar to the following sample displays:
VLAN 2 : 2 is defined as:
1. Description = MVLAN 2
2. Admin Status = Enabled
3. Rule Definition
Rule Num Rule Type Rule Status
1 Port Rule Enabled
2 Multicast Rule Enabled
Available options:
1. Set VLAN Admin Status
2. Set VLAN Description
3. Add more rules
4. Delete a rule
5. Set rule Admin Status
6. Quit
Option =
The first half of the display shows the current configuration of this multicast VLAN. For exam-
ple, this sample shows multicast VLAN 2 in Group 2 with a description, “MVLAN 2.” The multi-
cast VLAN is Enabled and a Port Rule has been set up and it is enabled.
The second half of the display shows a list of the multicast VLAN attributes you can modify.
You can modify basic information such as the Admin Status and Description. You can also
add rules, delete rules, and enable or disable a rule. To modify an attribute, enter the number
next to the option you want to modify and press <Enter>.
The following sections describe each of the six Available Options for the modmcvl command.
Changing a VLAN’s Admin Status
1. At the Option= prompt enter a 1 and press <Enter>.
2. The following prompt displays:
Set Admin Status to ((e)nable/(d)isable):
Type an e to enable the multicast VLAN or a d to disable it. An enabled VLAN starts using
policies to direct data flow. A disabled multicast VLAN is saved, but can not become
active.
The system returns to the Available Options menu. You can modify more attributes for this
multicast VLAN, or quit modifying the multicast VLAN by typing a 6.
