Switch configuration

...

  • An unique numeric identifier (1-40954999) for each group
  • Two or more local network interfaces (ethX, rfX, tunX, etc) and a set of rules (filters) which allow placing different types of traffic into different switching groups
  • Each node can have several switching groups. The same interfaces or group of interfaces can be used in several groups simultaneously
  • Switching groups are activated on different nodes of the MINT network. The nodes that have the same switching group identifier in their configurations represent a "switching zone"
  • "Switching zone" exists only within the MINT network segment.

...

If you enable the trunk group at the BS side to transmit several VLAN-flows to several directions, then at the CPE side, you should use the "In-Trunk" option to specify the group number of the trunk group that includes the required switching group.

Trunk During data transmission through a wired switch, the group number is automatically converted to the 802.1q VLAN tag, and vice versa, when a packet is received through the wired switch, the VLAN tag is converted to the corresponding group number.

Trunk groups may also be used to solve the task of connecting several VLAN segments.Special

Special rules on interfaces allow flexible manipulations with VLAN ID tags: deleting, assigning and re-assigning (please consult the information provided in WANFleX OS User Manual).

 In the "MAC Switch Group parameters" section, you can view the Switch Groups and Rules that are already created, including the management switch group; you can change the parameters for these Switch Groups, delete them by clicking the «Remove Group» button or create new ones by clicking the «Create Switch Group» button. The same operations are available for the switching rules: add a new rule within a switch group by clicking the «Add Rule» button (located within sub-menu "Rules" of this group) or delete an existing rule by clicking the «Remove Rule» button.

General options in this section: 

  • Enable Switch - enables/disables global switch operation
  • Max Sources - sets the maximum allowed number of records in the switch MAC address table. The default number of records is 5000.
  • STP MINT mode - enables/disables the STP MINT mode. STP MINT mode is used to exclude the wired switches with the enabled STP protocol influence on the network operation. The mode blocks the BPDU frames of the STP protocol configured on wired switches so that the switch cannot detect the loop and block its ports. STP MINT mode in conjunction with the RSTP protocol enabled in the Infinet devices allows to break the loop and support the PRF protocol functioning that operates through the wired segment.
Warning
titleCAUTION

 Disabling the switch in the absence of routing settings can lead to termination of packet transmitting through the device.

  • «Remove L3 Management» Management - by clicking this button you can delete the "sviX" interface, which is available in the default configuration, for the unit management
  • «Create L3 Management» Management - by clicking this button you can add an "sviX" interface for the unit management via Web interface (please consult the configuration examples presented in chapter "Configuration scenarios").

«Switch "Switch Group configuration» configuration" section:

titleTable - MAC Switch
Switch parameterDescription
Group #
  • Displays the Switch Group number
  • Assign the switch group identifier (must be unique within the MINT network segment)
Status
  • Select the Switch Group status: started, stopped or discard
Interfaces
  • Add Ethernet or/and Radio as Switch Group interface(s)  via the «Ports» button
  • "Select": pass (selected by default), strip or tag for VLAN tag modification for each added interface
  • The Interfaces section provides the means to control the VLAN tag processing mode, as each local interface supports three different scenarios:
  • "Pass" - transparent mode, traffic remains unchanged.
  • "Strip" - all tags are stripped.
  • "Tag" - all packets are tagged with the specified VLAN tag
  • Another option in this field is to remove one or both added interfaces
STP
  • Add an STP VLAN number in case that spanning tree support is enabled
Repeater
  • Enable/disable repeater support
  • The unit acts as a simple switch, relaying packets to all ports, except the source port
IGMP
  • Enable/disable IGMP snooping support
  • Please refer to the information provided in the next section for details
Flood
  • Allow/deny unlimited unicast flood without protection filter
Inband
  • Allow/deny access to the device through in-band broadcast/multicast management traffic
  • It is enabled by default
Mode
  • Set the working mode of the switching group: normal, trunk, in-trunk (give it the trunk group number created on the BS), upstream, downstream
  • Normal (standard mode) - the switch group operation is based on the configured Rules, packets are processed without modification (this is the default option)
  • Trunk - the inbound traffic is untagged and placed into switch groups in accordance with its VLAN tag
  • In-Trunk - allows filtering out the traffic that belongs to a certain switch group that is a member of a trunk Switch Group
  • Upstream - used mainly in video surveillance systems for upstream multicast flows
  • Downstream - used in video surveillance systems for downstream traffic
Description
  • Type a description sentence for the current switch group
Default Action
  • Set the default action: permit/deny
  • In the absence of any Switching rule, or if a packet does not match to any Switching rule, the default action for this group or interface is taken
Default QM Channel
  • Allocate a default logical channel
  • The default logical channel must be prior created in the "Traffic Shaping" section
  • In the absence of any Switching rule, or if a packet does not match to any Switching rule, the default logical channel is allocated
  • For the indications on how to create a logical channel, please refer to the "Traffic Shaping" section below
Default Priority
  • Allocate the default priority for all the packets going through the Switch group:
    • “Up to” - used to increase the packet priority to the specified value only if the processed packet has a lower priority
    • “Set” - used to assign a new priority regardless of the value already assigned to the packet
  • In the absence of any Switching rule, or if a packet does not match to any Switching rule, the default priority is allocated

In this section you can set the IGMP-parameters for the groups for which support of IGMP snooping is enabled (the IGMP check box is marked for these groups in the "MAC Switch" section).

IGMP Snooping is a multicast constraining mechanism that runs on Layer 2 devices to manage and control multicast groups. By listening to and analyzing IGMP messages, the device running IGMP Snooping establishes mappings between ports and multicast MAC addresses and forwards multicast data based on these mappings.
