Ethernet
In the default mode the Ethernet switch passes IP packets (up to 1522 bytes) as it receives them.
However, using SuperVisor you can configure VLAN, QoS and port speed settings to improve how IP
traffic is managed.
This is useful for operators who use virtual networks to segment different groups of users or different
types of traffic in their network. These groups can be maintained across the radio link thus ensuring
users in one virtual network cannot access data in other virtual networks.
The switch also has a high-speed address lookup engine, supporting up to 2048 preferential MAC
addresses as well as automatic learning and aging. Traffic is filtered through this table and only traffic
destined for the remote end is sent across the link improving bandwidth efficiency.
Note: You need "modify" or "admin" privileges to configure the Ethernet for VLAN and Quality of
Service (QoS).
VLAN tagging
By default, all user and management traffic is allocated the same VLAN across the link.
Alternatively, you can assign each of the four Ethernet ports to a VLAN. Each VLAN can be configured
to carry user traffic, or user traffic and radio management traffic. The VLAN tagging conforms to IEEE
802.1Q standard.
Configuring the Ethernet switch for VLAN tagging
1. Select Link or Local or Remote > Interface > Ethernet Settings.
Note: Always configure the remote terminal before the local terminal
2. In the Quick Links box at the bottom of the page, click Ethernet General Settings.
3. From Ethernet Grouping drop-down list select 'Enabled' ('Disabled' is the default setting; Ethernet
traffic is not segregated).
Important: Changing this setting will disrupt Ethernet traffic.
4. Click Apply to apply changes or Reset to restore the previous configuration.
You now need to select the VLAN groups for each of the four Ethernet ports.
