Configuring Physical Port Settings

With the set vlan CLI command, assign port 1, and port 2 to VLAN4 and

also assign port 4 to VLAN1 and VLAN2. Then PC1 and PC2 could

communicate with SERVER1 across VLANs without any noticeable

problems. However, when PC1 transmits a packet to SERVER1, the

following occurs:

The packet is sent to the Switch

The switch looks for the MAC address of SERVER1in the Address

Forwarding Table for VLAN1 (because this is the actual port VLAN

assigned to the port)

The switch will be unable to find an entry for the MAC address of

The switch will flood this packet to all ports assigned to VLAN1

(regardless of how the VLAN was assigned to the port)

* Note: The only exception to flooding a port is if 'Known

Mode' is set to enable on the port, which stops the

flooding of destination unknown unicast packets.

If you had many clients/servers on separate VLANs and they tried to

communicate over multiple VLANs using this method, you would flood

your network with undesired packets, thus slowing your overall network

performance. Currently, the best solution is to use a L3 module to route

between the VLANs. This would eliminate the broadcast of destination

unknown unicast packets.

You can configure the physical port parameters on 10-Gigabit ports by

using either the Web Agent or the CLI.
