ASYNC ROUTER AR-P, AR-5, AND SYNC ROUTER REFERENCE MANUAL

1.7 General Info

1.7.1ROUTER MODES & PROMPTS

The Router is always in either TCP/IP mode or IPX mode. The prompt on your terminal indicates the current mode of the Router (indicated by (tcp/ip)router_name> or (ipx)router_name>).

TCP/IP commands are only valid in TCP/IP mode (indicated by the prompt (tcp/ip)router_name>). IPX commands are only valid in IPX mode (indicated by the prompt (ipx)router_name>). Generic commands can be entered in either TCP/IP or IPX mode.

1.7.2FREQUENTLY-USED COMMANDS

About TCP/IP and IPX modes

Your Router has two modes: tcp/ip for TCP/IP networks and ipx for IPX networks. An interface (isdn1, eth0, modem0, modem1, etc.) can fail in tcp/ip mode, and still be operating in ipx mode simultaneously, up in both modes, or vice versa. When running both TCP/IP and IPX protocols simultaneously, as you bring an interface up or down, take note of whether your Router is in tcp/ip or ipx mode when you issue the command. If you want the interface up or down in the other mode as well, change to the other mode and issue the command again. To change modes, enter tcp/ip or ipx alone or as a prefix to the command.

These commands are often used to collect status information:

•asystat—Displays interface statistics. Use asystat to check current interface status (modem LEDs) and settings.

•config show—Displays the current configuration as a list of individual commands that execute when the Router starts. When you contact customer support, have a printed output of config show available to answer questions regarding your Router’s current configuration.

•dialup iface status—Displays the current dialup settings for a given interface. Dialup tells you how the line is configured (“client” for CLIENT-to-LAN operation and either “demand,” “demand_backoff,” etc., for LAN-to-LAN operation), total connection time, and quota information.

•ifconfig iface—Display and configure IPX and TCP/IP network interface parameters. Note that the output of ifconfig depends on the current mode of operation of the Router (either tcp/ip or ipx). Use ifconfig to determine Ethernet frame types, assigned IP addresses on interfaces (tcp/ip mode only), or IPX network numbers (ipx mode only), and the number of packets sent and received.

•netstat -m—Displays the amount of free memory, number of failed memory allocations, number of memory errors, and network usage statistics. This information may be useful when contacting Technical Support.

•netstat -s—Displays TCP/IP or IPX network statistics, depending upon the current mode (tcp/ip or ipx) of the Router. The netstat output is more detailed than the ifconfig network statistics output, and may also be useful when contacting Technical Support.

•version—Displays the current release level of the Router software.

Commands often used to troubleshoot problems include:

•config modify—Use config modify to check and verify your Router’s current configuration. Config modify prompts you through the configuration process and supplies defaults based on the current configuration.
