Default Level

Parameters
vlan-list: Specifies a 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.
all: Deletes all the sub-VLANs of the current multicast VLAN.
Description
Use the subvlan command to configure sub-VLAN(s) for the current multicast VLAN.
Use the undo subvlan command to remove the specified sub-VLAN(s) or all sub-VLANs from the
current multicast VLAN.
A multicast VLAN has no sub-VLANs by default.
Note that:
The VLANs to be configured as sub-VLANs of the multicast VLAN must exist and must not be
multicast VLANs or sub-VLANs of another multicast VLAN.
The number of sub-VLANs of the multicast VLAN must not exceed the system-defined limit (an
S7900E 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.
