Configuring WAN Port Settings
6-8 PortMaster Configuration Guide
Setting the Transport Protocol
The transport protocol for synchronous connections must be set for a network
hardwired synchronous port. Choose PPP for leased line, switched 56Kbps, and ISDN
connections, or Frame Relay for a Frame Relay connection. Additional Frame Relay
settings must be configured for Frame Relay connections, described in Chapter 13,
“Using Frame Relay.”
To set the transport protocol, use the following command:
Command> set W1 protocol ppp | frame
Setting the Port IP Address
You can set the local IP address of the network hardwired synchronous port to create a
numbered interface.
You can use any IP address. If you set the local address of the WAN port to 0.0.0.0 for
PPP, the PortMaster uses the Ether0 address for the end of the serial link. If you set the
WAN port address to 0.0.0.0 for a Frame Relay connection, the port is disabled.
To set the IP address, use the following command:
Command> set W1 address Ipaddress
Setting the Destination IP Address
The destination IP address or hostname of the machine on the other end of the
connection is used for leased line connections only. The destination IP address can also
be set to 255.255.255.255 for PPP users. This setting allows the PortMaster to learn the
IP address of the system on the other end of the connection using PPP IPCP address
negotiation.
Do not set a destination IP address for Frame Relay connections. Instead, use the data
link connection identifier (DLCI) list to link IP addresses to DLCIs, or use LMI or Annex-
D and Inverse ARP to discover Frame Relay addresses dynamically. See Chapter 13,
“Using Frame Relay,” for more information.
For network dial-in or dial-out connections, do not set a destination IP address for the
port. Instead, you set the destination address in the user table or RADIUS for dial-in, or
in the location table for dial-out. See Chapter 7, “Configuring Dial-In Users,” and
Chapter 8, “Configuring Dial-Out Connections,” for more information.
