H3C S7500E Series Ethernet Switches Chapter 2 Multicast VLAN Configuration Commands
2-3
subvlan vlan-list: Defines one or multiple VLANs as sub-VLANs. You can provide up to
10 VLAN lists, by each of which you can specify an individual VLAN in the form of
vlan-id, or a VLAN range in the form of start-vlan-id to end-vlan-id, where the end VLAN
ID must be greater than the start VLAN ID. The effective range of a VLAN ID is 1 to
4094.
Description
Use the multicast-vlan subvlan command to configure sub-VLAN(s) for the specified
multicast VLAN.
Use the undo multicast-vlan subvlan command to remove the specified sub-VLAN(s)
from the specified multicast VLAN.
A multicast VLAN has no sub-VLANs by default.
Note that:
z The VLAN to be configured as the multicast VLAN and the VLANs to be configured
as sub-VLANs of the multicast VLAN must exist.
z The VLANs to be configured as sub-VLANs of the multicast VLAN must not be
multicast VLANs.
z The VLANs to be configured as the sub-VLANs of the multicast VLAN must not be
sub-VLANs of another multicast VLAN.
z The number of sub-VLANs of the multicast VLAN must not exceed the
system-defined limit (an S7500E series Ethernet switch supports up to five
multicast VLANs, and supports up to 4000 sub-VLANs for each multicast VLAN.
The total number of sub-VLANs for all multicast VLANs on the switch cannot
exceed 4000).
Examples
# Configure VLAN 10 through VLAN 15 as sub-VLANs of multicast VLAN 100.

[Sysname] multicast-vlan 100 subvlan 10 to 15
