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

ple, this sample shows multicast
VLAN

cast
VLAN

VLAN
attributes you can modify.
