Configuring network settings
To configure the network settings on the Cisco TelePresence ISDN Gateway and check the network
status, go to Network > Port A or Network > Port B.
The ISDN Gateway has two Ethernet interfaces, Port A and Port B. The configuration pages for the two
interfaces look and behave similarly, and so are described together. Differences will be noted as
appropriate.
Port A and Port B can be configured to be allocated their IP address by DHCP (IPv4) or SLAAC/DHCPv6
(IPv6). Connect Port A to your local network and connect Port B to a second subnet or the internet
depending on your application of the ISDN Gateway.

configuration fields below.

DHCP this setting will be ignored.
