config interface ether physical show
Display the current physical address of the ethernet
The physical ethernet address is a 48-bit unique address preset during manufacturing. The
physical address is the lowest hardware ID for that ethernet device and was assigned by the
manufacturer. Use this command to check the physical ethernet address.
config interface ether show

5.4 Configure ISDN Interface, Authentication and VJ compression
config interface isdn ip address <IP address> <netmask>
Configure the ISDN interface with the IP address <IP address> and the netmask <netmask>
Like the
IP address
and
netmask
configured for the LAN interface, sometimes you need to setup
the
IP address
and
netmask
for the WAN/ISDN (Wide Area Network) interface for LAN-to-
LAN application or static IP address requested by the ISP (Internet Service Provider) site. Under
normal situation you don’t need to setup the WAN
IP address
as most of the ISP will
assign the IP address to the router dynamically.
config interface isdn ppp authen <pap,chap,both>
Configure the authentication protocol when the PPP or ML-PPP connection is established.
When establishing the connection with the remote site under PPP or ML-PPP protocol, it is
necessary to specify the authentication mechanism by both parties. If
pap
(Password
Authentication Protocol) is selected the router will use PAP only, the PAP will send username and
password in plain text for authentication. If
chap
(Challenge Handshake Authentication
Protocol) is selected the router will use CHAP only, the CHAP will scrambles the password
And sent for authentication. If
both
is selected, the router will try PAP when remote site
requested PAP or it will try CHAP when remote site requested CHAP.
config interface isdn ppp ipcp vjcompression
Turn on the VJ (Van Jacobson) compression function for IP header.
The VJ compression is a mechanism to compress the IP header of a packet during transmission
