Chapter 7 Multiple ESS and VLAN 90

7.2 VLAN

A VLAN (Virtual Local Area Network) allows a physical network to be partitioned into

multiple logical networks. Stations on a logical network can belong to one or more groups.

Only stations within the same group can talk to each other.

7.2.1 VLAN Tagging

The ZyAIR supports IEEE 802.1q VLAN tagging. Tagged VLAN uses an explicit tag (VLAN

ID) in the MAC header of a frame to identify VLAN membership. The ZyAIR can identify

VLAN tags for incoming Ethernet frames and add VLAN tags to outgoing Ethernet frames.

7.2.2 Second Rx VLAN ID

The ZyAIR tags Ethernet frames in VLAN 1 with VLAN ID 1 and tags Ethernet frames in

VLAN 2 with VLAN ID 2. Both VLAN 1 and VLAN 2 have Internet access. VLAN 1 and

VLAN 2 have access to a server. Ethernet frames forwarded from the server back to the switch

are tagged. Ethernet frames are tagged with a second Rx VLAN ID (incoming VLAN ID).

These incoming VLAN packets are forwarded to the ZyAIR. The ZyAIR matches the Second

Rx VLAN ID with VLAN ID. See the table in Figure 7?2.

Hex Select this option to enter hexadecimal characters as the WEP keys.The

preceding “0x” is entered automatically.

Unicast WEP key

Key 1 or Key 2 Key 1 or key 2 is used to encrypt unicast transmissions.

If you chose 64-bit WEP, then enter any 5 ASCII characters or 10

hexadecimal characters ("0-9", "A-F").

If you chose 128-bit WEP, then enter 13 ASCII characters or 26 hexadecimal

characters ("0-9", "A-F").

You must configure both keys, but only one key can be activated at any one

time. The default key is key 1.

Broadcast/Multicast

WEP key

Key 3 or Key 4 Key 3 or key 4 is used to encrypt multicast/broadcast transmissions.

If you chose 64-bit WEP, then enter any 5 ASCII characters or 10

hexadecimal characters ("0-9", "A-F").

If you chose 128-bit WEP, then enter 13 ASCII characters or 26 hexadecimal

characters ("0-9", "A-F").

You must configure both keys, but only one key can be activated at any one

time. The default key is key 3.
