To configure Ethernet Port A, enter the following for auto-sensing mode:

ethertype A auto

or to configure a speed and duplex, use the following command:

ethertype A <10|100> <half|full>

To display the current configuration and status of the Ethernet ports, enter:

status

For example, to configure a full-duplex 100 Mbps link, enter:

ethertype A 100 full

To establish a 1000Mbps connection, both ends of the link must be

configured as auto-sensing.

Step three: Assign an IP address to the ISDN gateway (optional)

The default setting for the ISDN gateway is to use DHCP to obtain an IP address. You

can assign a static IP address if you prefer or if a DHCP server is not available. If you

want the IP address of the ISDN gateway to be assigned by your DHCP server, omit

this step.

From version 2.1, ISDN gateway software supports IPv4 and IPv6

addressing. Default setting: Port A is configured to assign an IPv4 address

using DHCP; IPv6 on Port A is disabled.

From Version 2.1:

To assign a static IPv4 address to Port A, use the following command:



static A <IP address> <netmask> [<default gateway address>]

For example, to assign an address of 192.168.1.2 where the default gateway is at

192.168.1.1, enter:

static A 192.168.1.2 255.255.255.0 192.168.1.1

To set DNS manually, use this command:



dns <DNS server address> [<secondary DNS server>][<domain>]

To return to using DHCP after setting a static IPv4 address, use the following



command:

dhcp -4 A
