Summary

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

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.

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.
-interactive button "Create Static"	This action will reserve currently assigned IP address for the device in [[{{{name}}}_DHCP#Static Leases|Here]]

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-{{{name}}}:~# 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-{{{name}}}:~# 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-{{{name}}}:~# 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-{{{name}}}:~# 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-{{{name}}}:~# 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

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

IPv6 Neighbours
