Use the unknown-unicast parameter to specify CPU flooding for unknown unicast packets only.
NOTE
This command does not erase any multicast or unknown-unicast flooding configuration. If this
command is enabled, then it supersedes the per-vlan configuration.

Configuring uplink ports within a port-based VLAN

You can configure a subset of the ports in a port-based VLAN as uplink ports. When you configure
uplink ports in a port-based VLAN, the device sends all broadcast and unknown-unicast traffic from
a port in the VLAN to the uplink ports, but not to other ports within the VLAN. Thus, the uplink ports
provide tighter broadcast control within the VLAN.
For example, if two ports within a port-based VLAN are Gigabit ports attached to the network and
the other ports in the VLAN are 10/100 ports attached to clients, you can configure the two ports
attached to the network as uplink ports. In this configuration, broadcast and unknown-unicast
traffic in the VLAN does not go to all ports in the VLAN. The traffic goes only to the uplink ports.
The clients on the network do not receive broadcast and unknown-unicast traffic from other ports,
including other clients.
To configure a port-based VLAN containing uplink ports, enter commands such as the following.
BigIron RX(config)# vlan 10 by port
BigIron RX(config-vlan-10)# untag ethernet 1/1 to 1/24
BigIron RX(config-vlan-10)# untag ethernet 2/1 to 2/2
BigIron RX(config-vlan-10)# uplink-switch ethernet 2/1 to 2/2
Syntax: [no] uplink-switch ethernet <port-number> [to <port-number> | ethernet <port-number>]
In this example, 24 ports on a 10/100 module and two Gigabit ports on a Gigabit module are
added to port-based VLAN 10. The two Gigabit ports are then configured as uplink ports.

Configuring control protocols in VLANs

You can configure the following protocols on a VLAN:
•
•
•
•

Other configuration options

You can also configure the following on a VLAN:

Displaying VLAN information

After you configure the VLANs, you can view and verify the configuration.
