Chapter E. Virtual Local Area Network
E.1 Bridge and VLAN Mode
PacketMax products may be deployed in following modes of operation:
 Bridge Mode: In the bridge mode, data and management traffic is forwarded.
 VLAN Mode: Virtual Local Area Networks (VLANs) is a method that allows
network administrators to create logical broadcast domains, which implies
division of local area network by software rather than using cables. The
broadcast domains can span across one switch or multiple switches. Thus
VLANs:
- Reduces the size of broadcast domains
- Reduces network traffic
- Increases Network security
- Reduces the need to create subnetworks
- Enables network to be logically separated and not physically.
For the Data Traffic in the VLAN Mode, the VLAN IDs are configured when
provisioning SS using EMS.
E.2 Out of band Management with Management
VLAN
Outbound Management traffic adds security, when the management VLAN is
enabled. The outbound management is tagged with this VLAN ID. Both BS and SSs
should use same VLAN ID as Management VLAN ID. For example, if VLAN ID num
-
ber is 1 on BS, it has to be the same (VLAN ID 1) on SS as well. The management
VLAN ID needs to be set:
 On the PM5000 BS, manually.
NOTE: Changing Management Port in VLAN requires MSC reboot.
 On the SS, using the Installation Manager.
Please refer to Chapter 6 “Commissioning the Base Station”, for setting up Manage-
ment VLAN ID on the BS and refer to the PacketMax 100/300 User Manual for setting
up the Management VLAN ID on the SS.
Typically management port is used for sending/receiving management traffic (Ping/
TFTP/DHCP packets from/to BS or SS).
Figure E-1 displays DHCP/TFTP over man-
agement port (a management interface set-up).
