Private VLANs on Rapier 48i Switches
The ports on Rapier 48i switches are divided into two instances:
• ports 1-24 plus uplink port 49
• ports 25-48 plus uplink port 50
Private VLANs on a Rapier 48i switch can consist of only ports from one
instance. Both the private ports and the uplink port must be in the same
instance.
Configuring Private VLANs
To create a private VLAN and add ports to it:
1. Create the VLAN
To create a VLAN and specify that it is private, use the command:
create vlan=vlan-name vid=2..4094 private
2. Add the uplink port or trunk group
To add the uplink to a private VLAN, use one of the commands:
add vlan={vlan-name|1..4094} port=port-list
[frame={untagged|tagged}] uplink
where port-list is either a single port number for a single uplink port, or a
list of port numbers for a trunk group. If you are adding a trunk group to
the VLAN as an uplink, the ports must already be trunked together, and
you must specify all the ports.
3. Add the private ports
To add a private port or ports to a private VLAN, use one of the
commands:
add vlan={vlan-name|1..4094} port={port-list|all}
[frame={untagged|tagged}] [group]
The group parameter specifies that the listed ports may communicate with
each other, but not with any other private ports in the VLAN.
4. Delete ports from a private VLAN as necessary
To delete private ports from a private VLAN, use one of the commands:
delete vlan={vlan-name|1..4094} port=port-list
delete vlan={vlan-name|1..4094} port=all
A private VLAN cannot contain private ports when an uplink is deleted
from the VLAN, because a private VLAN must always have an uplink. To
delete the uplink port or ports and any private ports from a private VLAN,
use the port=all option in the above command.
If the port is a member of a private group, you must delete all ports in the
group at once. This stops groups from having different member ports in
different VLANs.
