Switch

The switch page allows you to configure the ports of the unit and the switching related features.

Figure- Unit Scheme

The following 5 ports are available at the unit:

"ge0" and "ge1" - external copper Gigabit Ethernet ports 1000BASE-T (IEEE 802.1ab).
"sfp" - external optical Gigabit port for plugging of the optical SFP transceiver module.
"radio" - internal radio interface of the device.
"mgmt" - internal interface for the device management.

Figure - Switch section

"Switch Port Settings" - allows you to perform general port configuration.

Figure - Switch Port Settings

Parameter	Description
Up	You can enable or disable the port status
Egress Rate Limit	You can set the limit (traffic shaper) on the selected port, for outgoing traffic, in Mbps, from 1 to 100 in increments of 1, from 100 to 1000 in increments of 10, or to set it unlimited
QoS mode	You can select the traffic shaper policy for the port, WRR is selected by default “Weighted Round Robin” - weights are used for every queue of an interface, which allows different queues to have different service shares depending on the weight value “Strict” - packets within lower priority queue are not processed if the higher priority queue is not empty
Port Mode	You can select the physical port operational mode from: auto: the speed and operational mode of the port will be negotiated between the 2 end points 10BaseT-halfduplex;10BaseT-halfduplexmanual; 10BaseT-fullduplex;10BaseT-fullduplex-manual 100BaseTX-halfduplex; 100BaseTX-halfduplex-manual; 100BaseTX-fullduplex; 100BaseTX-fullduplex-manual 1000BaseTX-fullduplex;1000BaseTX-fullduplex-manual

Table - Port parameters

NOTE

Manual settings for the "Port Mode" will disable the negotiation and detection for speed and duplex. Use them in case that the interconnected 3rd party switches have fixed speed and duplex settings.

"Connectivity Matrix" allows you to enable or disable switching between internal and external ports of the switch.

Figure - Connectivity matrix

In "Transparent" mode packet switching is allowed between external and internal ports, in case of VLAN-based Switching enabled switching is performed by VLAN tags.

"VLAN-based Switching" allows to create list of allowed VLANs and their handling on the unit switch plane. Without such option active, wireless link works as transparent Layer 2 bridge. Thus, the link transport any frames with any VLAN tags set.

Figure - VLAN-based Switching

Mode

Description

off

Denies all traffic of a specific VLAN

Tagged

Operates as trunk port, allows tagged traffic of a specific VLAN to pass through this port

Untagged

Operates as trunk port, allows untagged traffic of a specific VLAN to pass through this port

Access

Operates as access port, allows only untagged traffic

Priority

Allows to set the priority of a specific VLAN according to 802.1p ranging from 0 to 7, where 0 - the lowest priority level, 7 - the highest.
There are four priority queues. The mapping between 802.1p priorities and 4 queues can be found below

802.1p priority	Traffic type	Unit priority queue
0	Background	1
1	Best Effort	1
2	Excellent Effort	2
3	Critical Applications	2
4	Video	3
5	Voice	3
6	Internetwork control	4
7	Network control	4

Figure - VLAN modes

NOTE

The "Default VLAN" is configured by default as «Untagged» for all ports of the switch:

In case the "VLAN-based Switching" is enabled, only untagged traffic will be transmitted through the unit ports in such configuration.
In case the "VLAN-based Switching" is disabled, tagged and untagged traffic will be transmitted through the unit ports. In this case, the connectivity matrix between external interfaces and mgmt interface are enabled, device will be available through any of assigned IP addressess.

"Default VLAN" could not be deleted.

NOTE

VLANs could be created with ID from 2 to 4094. It is possible to set the ranges of VIDs not just individual tags when configuring VLANs.

For more detail information about VLAN configuration please refer to the section "VLAN Switching".
