The switch can operate in one of the following modes: "isolate" or "transparent".

In "isolate" mode, packet switching is based on the port isolation rules. External ports are isolated from each other and traffic from each of them is redirected to the internal ports according to the port isolation rules, so that any direct traffic between the external ports is impossible. This is the basic mode, used by default, including situations when there are no any VLAN settings or 802.1Q-support is disabled in "transparent" mode.

In "transparent" mode, direct traffic transmission between external ports (without involving the internal ones) is possible, packet switching is performed according to the VLAN-tags and internal “port - VLAN-tag” correspondence table, if it exists.

Default settings

  • By default the switch operates in "isolate" mode, i.e. all the ports are isolated from each other, even if they are located in the same VLAN
  • All the ports operate in "trunk" mode with "native VLAN 1" for untagged traffic
  • radio interface is up and operates within the switch as a regular port
  • DHCP-client is enabled on the management interface "mgmt".

"port" command

Use this command for the built-in switch management.

Command arguments description is given in the table below:

CommandDescription
port [-scheme=SCHEME]
  • Select one of the switch modes:
    • isolate
    • transparent
port [-mgmt=PORT_SET] [-radio=PORT_SET]
  • Configure the port isolation rules for traffic redirection from external physical interfaces "ge0", "ge1" and/or "sfp" to the interfaces "radio" or "mgmt"
port -d1q[=[disable|enable]]
  • Disable/enable the switching rules based on VLAN-tags of the 802.1Q standard
  • In order to enable switching based on the port isolation rules even if the "transparent" mode is selected, disable the switching rules based on VLAN-tags of the 802.1Q standard
port -vlan={RANgeLIST}
  • Add VLANs to the system with numbers from 1 to 4094

Example,

port -vlan=50,52,60-64

adds VLANs 50, 52, 60, 61, 62, 63, 64

port -remove={RANgeLIST}
  • Remove any previously created VLANs from the system
port -vlan={RANgeLIST} {-priority=PRIO}
  • Set for the selected VLANs the priority according to 802.1p ranging from 0 to 7, where 0 - the lowest priority level, 7 - the highest

Example,

port -vlan=50 -priority 7

sets the priority 7 (Network control) to the VLAN 50

port -vlan={RANgeLIST} {-nopriority}
  • Remove the previously set priority for the selected VLAN
port -vlan={RANgeLIST} [-stp]
  • Enable STP support for the selected VLANs
  • Enable on the switch the support of PVST+ (Per-VLAN Spanning Tree Plus) protocol – the special version of STP, which allows creating a separate spanning tree for each VLAN
port -vlan={RANgeLIST} [-nostp]
  • Disable STP support for the selected VLANs
port -vlan={RANgeLIST} {-spriority=STPPRIO}
  • Set the bridge priority for STP in the selected VLAN ranging from 0 to 61440 in increments of 4096 (or from 0 to 16 in increments of 1)

If you need to allow both tagged and untagged traffic through the port, you can configure the "native VLAN" option that defines the only VLAN for receiving of all incoming untagged traffic in "trunk" mode ("VLAN 1" is configured as a "native VLAN" for all the ports of the switch by default)
port [PORT_SET] [-access=TAG]
  •  Define VLANs for the port operation in "access" mode

Example,

port 0 -access=50 -mode=access

sets the "access" mode for the port "ge0" and defines VLAN 50 for this port operation

Configuration examples

Configure the switch for operation in "isolate" mode. It is the default mode. If you need to switch from "transparent" mode, use the command:

  • port -scheme= isolate

Configure the port isolation rules for traffic redirection from external physical interfaces "ge0", "ge1" and/or "sfp" to the interfaces "radio" or "mgmt":

Assign access to the management interface through the "ge0" port:

  • port -mgmt=0

Assign the port "ge1" for data transfer to the port "radio":

  • port -radio=1

Configure the switch for operation in "transparent" mode.

See VLAN-based switching matrix with default settings below:

port vtt
        VID  0 1 2 r m STP Prio
        ==== = = = = = === ====
           1 N N N N N  - ----

In order to switch to "transparent" mode, execute the command:

  • port -scheme=transparent

Configuring of the switch starts with adding VLANs, which are necessary for data transfer and device management:

port -vlan=30,100
port vtt
        VID  0 1 2 r m STP Prio
        ==== = = = = = === ====
           1 N N N N N  -  ----
          30 t t t t t  -  ----
         100 t t t t t  -  ----

Set the parameters of processing of tagged or/and untagged traffic for each port.

Set access of untagged packets to VLAN 30 on the management interface "mgmt":

port m -access=30 -mode=access
port vtt
        VID  0 1 2 r m STP Prio
        ==== = = = = = === ====
           1 N N N N -  -  ----
          30 t t t t A  -  ----
         100 t t t t -  -  ----

Set access of untagged packets only to VLAN 30 on the port "ge0":

port 0 -access=30 -mode=access
port vtt
        VID  0 1 s r m STP Prio
        ==== = = = = = === ====
           1 - N N N -  -  ----
          30 A t t t A  -  ----
         100 - t t t -  -  ----

Set the "ge1" port for processing of tagged packets of the VLAN 30 only ("trunk" mode):

port 1 -allow=30 -mode=trunk
port vtt
        VID  0 1 s r m STP Prio
        ==== = = = = = === ====

          30 A t t t A  -  ----
         100 - - t t -  -  ----

Set the port "sfp" for processing of tagged packets of the VLAN 100 only ("trunk" mode):

port s -allow=100 -mode=trunk
port vtt
        VID  0 1 s r m STP Prio
        ==== = = = = = === ====
           1 - - - N -  -  ----
          30 A t - t A  -  ----
         100 - - t t -  -  ----

Set the port "radio" for processing of tagged packets of the VLAN 30 and VLAN 100 ("trunk" mode):

portr -allow=30,100 -mode=trunk
port vtt
        VID  0 1 s r m STP Prio
