Ethernet Switch
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.
