Identifying your router's MAC Address
Identifying your router's MAC Address
Every Ethernet interface has a unique hardware ID, known as its MAC address. This includes WAN ports, LAN ports and even Wireless LAN 'ports' (which simulate a wired interface).
A MAC address may or may not be shown or entered with dashes for ease of reading, e.g. 00-FF-12-43-55-33 or 00FF12435533.
Your MAC address can be found on the main/first page of the router's web interface when you log in. The LAN MAC address is highlighted in yellow in the diagram below.
Further down on the same page you will also find the WAN and Wireless LAN MAC addresses, however, if you do need the router's MAC address, most commonly it will be the LAN MAC address that is required:
If you only have telnet access then you can use the telnet command 'sys iface' and the MAC addresses and interface statuses will be shown. The first MAC address shown is the first LAN MAC address.

MAC address - Media Access Control address. MAC addresses - hardware addresses that uniquely identifies each node of a network. It is assigned by the vendor or manufacturer and saved to the device memory.
According to the OSI model it is a second-level address. In IEEE 802 networks Data Link Control (DLC) layer is divided into two sub-layers: the Logical Link Control (LLC) layer and the Media Access Control (MAC) layer.
First 3 bytes (or 24 bits) of MAC
addresses are known as the Organizationally Unique Identifier (OUI) and usually encodes the manufacturer.
MAC addresses usually are written in the six groups of two hexadecimal digits separated by colons (:) or hyphens (-), e.g. e8:04:62:90:07:62, 00-1E-37-18-50 DB.
It is also used in another form (e.g. vendor Cisco) - the three groups of four hexadecimal digits separated by dots (.), e.g. 0016.4d2e.7d10.
How you can identify MAC address and check MAC adress?
Windows(XP,7,Vista,8):
In
the command prompt (CMD), type in getmac (or getmac /v /fo list for full info).
Linux/Unix: type ifconfig -a. You must be root user or have appropriate permissions.
Mac OS X: launch the Terminal and type ifconfig.
Cisco: in the CLI type e.g. show arp.

The MAC Address Table contains up to 8192 entries, and is sorted first by VLAN ID, then by
MAC address.
Each page shows up to 999 entries from the MAC table, default being 20, selected through the
"entries per page" input field. When first visited, the web page will show the first 20 entries
from the beginning of the MAC Table. The first displayed will be the one with the lowest
VLAN ID and the lowest MAC address found in the MAC Table.
The Start from MAC address and VLAN input fields allow the user to select the starting
point in the MAC Table. Clicking the Refresh button will update the displayed table starting
from that or the closest next MAC Table match. In addition, the two input fields will assume
the value of the first displayed entry, allowing for continuous refresh with the same start
address.
The button >> will use the last entry of the currently displayed VLAN/MAC address pairs as a
basis for the next lookup. When the end is reached the text "no more entries" is shown in the
displayed table, use the l<< button to start over.
