The information in this page is updated in accordance with firmware version TSW2_R_00.01.03.1.

Summary

The Network page contains information related to the device's networking. This chapter is an overview of the Network page in TSW202 devices.

Forwarding Table

The Forwarding Table also known as MAC table, is most commonly used in network bridging, routing, and similar functions to find the proper output network interface controller to which the input interface should forward a packet. It is a dynamic table that maps MAC addresses to ports.

field name description
Port Name of physical port.
VLAN VLAN assigned to that port.
MAC Address MAC address of devices connected to that port.

Ports

The Ports table shows usage of the ports. The Port Load Status page provides real-time monitoring and detailed metrics of network port utilization, including traffic load and transmission and reception rates, to ensure optimal network performance

The Port Traffic Error Status table shows if there is any errors in the traffic.


Spanning Tree

The table shows the Spanning Tree states of each port.

Field name Value Description
Port port number Name of physical port.
Protocol Inactive | STP | RSTP Protocol used by the port.
State Inactive | Learning | Forwarding | Blocking | Listening | Discarding State of the port.
Role Inactive | Root | Designated | Alternate | Backup Role of the port. Roles are used only for RSTP.
Port cost integer Cost of the port is determined by the port speed. Higher speed ports have lower cost. Lower cost is more preferred by spanning tree.
Port priority integer Priority of the port is used when costs of the ports are the same. Lower priority is more preferred by spanning tree. Also the lowest priority port is put into forwarding state.

DHCP Leases

The DHCP Leases table shows information about hosts and the time period for which a DHCP server allocates a network address to a client. User can filter out all leases by interface. Also interface and leasetime remaining fields can be sorted.

field name description
Host name Client name.
IP address Leased IP address.
MAC address MAC address of the device.
Leasing remaining Remaining time on the lease.

Routes

ARP

The Address Resolution Protocol (ARP) is a communication protocol used for mapping an Internet Protocol address (IP address) to a physical machine's link layer address (MAC address) belonging to the local network.

The ARP section displays the router's ARP cache (also known as ARP table) data. The ARP cache contains information on each known MAC address and its corresponding IP address. When the router receives a packet destined for a local host, the ARP program attempts to find a physical host or MAC address in the ARP cache that matches the IP address. If the ARP cache doesn't contain the needed IP address, ARP broadcasts a request packet to all LAN machines in order to find the device with the IP address in question.

The figure below is an example of the ARP cache section:

Field name Value Description
IP address ip; Default: none IP address of a local host.
MAC address mac; Default: none MAC address of a local host.
Interface string; Default: none Interface through which the router is associated with the host.

You can also view the ARP cache via shell using the arp or ip neigh commands, depending on which output your prefer: 

root@Teltonika-TSW202:~# arp
IP address       HW type     Flags       HW address            Mask     Device
192.168.11.126    0x1         0x2         00:1e:42:00:00:00     *        br0.1

root@Teltonika-TSW202:~# ip neigh
192.168.11.126 dev br0.1 lladdr 00:1e:42:00:00:00 STALE

IPv4 Routes

The IPv4 Routes section displays the router's routing table. A routing table contains a list of routes to network destinations associated with and known by the router.

The figure below is an example of the Active IP routes section:

Field name Value Description
Network string; Default: none Associated network interface name.
Target ip | ip/netmask; Default: none Destination network address.
IPv4 gateway ip; Default: none Indicates the IP address of the gateway through which the target network can be reached.
Metric integer [0..4,294,967,295]; Default: none Metrics help the router choose the best route among multiple feasible routes to a destination. The route will go in the direction of the gateway with the lowest metric value.
Table string | integer; Default: none Name or number of the associated routing table.

You can also view the routing table via shell using the route or ip route commands, depending on which output your prefer: 

root@Teltonika-TSW202:~# route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
default         RUTX12.lan      0.0.0.0         UG    2      0        0 br0.1
192.168.11.0    *               255.255.255.0   U     1      0        0 br0.1
192.168.12.0    *               255.255.255.0   U     2      0        0 br0.1



root@Teltonika-TSW202:~# ip route
default via 192.168.12.1 dev br0.1 proto static src 192.168.12.125 metric 2 
192.168.11.0/24 dev br0.1 proto static scope link src 192.168.11.2 metric 1 offload 
192.168.12.0/24 dev br0.1 proto static scope link src 192.168.12.125 metric 2 offload

IPv6 routes

The IPv6 Routes section displays the router's IPv6 routing table.

The figure below is an example of the IPv6 routes section:

Field name Value Description
Network string; Default: none Associated network interface name.
Target ip6 | ip6/netmask; Default: none Destination network address.
IPv6-Gateway ip6 | ip6/netmask; Default: none Source of the network address.
Metric integer [0..4,294,967,295]; Default: none Metrics help the router choose the best route among multiple feasible routes to a destination. The route will go in the direction of the gateway with the lowest metric value.
Table string | integer; Default: none Name or number of the associated routing table.

You can also view the routing table via shell using the route -A inet6 or ip -6 route show commands, depending on which output your prefer: 

root@Teltonika-TSW202:~# ip -6 route
fda0:4802:e99d::/48 from fda0:4802:e99d::/64 via fe80::21e:42ff:fe5a:7a10 dev br0.1 proto static metric 512 pref medium
fda0:4802:e99d::/64 dev br0.1 proto static metric 256 pref medium

fe80::/64 dev eth0 proto kernel metric 256 pref medium
fe80::/64 dev br0 proto kernel metric 256 pref medium
fe80::/64 dev br0.1 proto kernel metric 256 pref medium

IPv6 Neighbours

The IPv6 Neighbours section displays IPv6 associated neighbours.

The figure below is an example of the Active IPv6 Neighbours section:

Field name Value Description
IPv6 Address ip6; Default: none IPv6 address of the associated neighbour.
MAC Address ip6; Default: none MAC address of the associated neighbour.
Interface string; Default: none Name of the associated network interface.
