The number of character(s) required for that command depends on if there is a similar command (spelling) to it.
5.1 Quick Configuration to Internet Before you can connect your LAN to the Internet you must obtain an ISDN internet account from your local Internet Service Provider (ISP). Your local ISP should provide you the following information when you register with them: 1. Account user ID and password 2. Dial in telephone number, you may need to have two phone numbers if you wish to run Multilink Point-to-Point Protocol (ie. MLPPP).
Quick Configuration Setup (ESC, ESC to exit) -------------------------------IP address of this unit's LAN port : 123.97.35.7 IP mask of this unit's LAN port : 255.255.255.0 Switch Type (etsi, ni1, ntt) : ni1 DN1 : 3930219 DN2 : 3930237 SPID1 : 50839302190101 SPID2 : 50839302370101 Phone number of the remote unit : 8398111 User's ID to log into remote site : john User's password to log into remote site : master CLI> config save At this point the unit is configured.
5.2 Complete Command Set The commands can be loosely grouped into two categories: show and config. The show will display a category of information and config will configure that category. The following command is available at all level in the menu. ? Display all the available commands for that level. help Display all the available commands for that level with a description for each. quit Go up one level toward the top, that is the root. 5.
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 Display the current settings of the ethernet interface 5.
by reducing the size of IP header for speeding up transmission performance. The remote site must also support the VJ compression, otherwise the router won’t compress the IP header if the remote site did not support the VJ compression. It is suggested to turn on VJ compression. config interface isdn ppp ipcp none Turn off the VJ compression function. 5.4.1 Configure Dial-In and Call Back Function config interface isdn ip pool Configure the IP address assignment of the PPP connection.
you need to setup phone#1 and phone#2, the router will make an outgoing connection by dialing phone#1 and phone#2. If under ML-PPP connection but just setup phone#1 then the router will make an outgoing connection by dialing the phone#1 twice. If callback is set to ‘yes’, then after the router checks valid dial-in username and password, it disconnects immediately. It also calls back to the remote site based on the remote site’s telephone number.
5.4.3 Configure BOD (Bandwidth On Demand) config interface isdn ppp bod incre decre Set bandwidth-on-demand to router. By default BOD is enabled on the router. Bandwidth on Demand (BOD) is a feature that allows the second telephone line connection to the internet to be made only if there is enough traffic between the router and the internet which exceeds the capacity of the first telephone line connection.
5.4.4 Configure ISDN Switch Type and Directory Number config interface isdn switch type {etsi,ntt,ni1} Configure the switch type for an ISDN interface Check with your local PTT to setup proper ISDN switch type otherwise the router may not operate correctly. etsi : European DSS1 switch (also called NET3) ntt : Japan INS64 switch (also called NTT-KDD) ni1 : Northern American National ISDN-1 switch You should check the supported switch type by your router by typing ATI2 in AT command mode.
config system login Change the login name to enter into CLI. The default login name is ‘admin’. It is suggested to change the login ID for security reason, furthermore to prevent illegal entry. config system password Change the login password to enter into CLI. The default login password of this router is ‘admin’ . It is suggested to change the login password for security reason, furthermore to prevent illegal entry.
reset Reset the router. All current configuration will be omitted if it wasn’t saved (config save) before hand. The reset function will restart the router with new configuration stored by config save. The router will start up in AT command mode. uptime Display the current time elapsed since the router was booted. version (currently implementing) Display the software and firmware version. 5.6 Configure IP Routing Table There are two ways to construct the routing table.
config ip route add default Add the default route to the routing table. This command is similar to the one above except for the command will take effect immediately if the gateway is determined to be reachable by the router. Otherwise, the command has no effect. config ip route add Add the static route of to the routing table with hop away.

udp Matches UDP packets The address specifies from
[port] to [port] [via ] You can only specify port in conjunction with protocols which support ports (UDP and TCP). The via is optional and may specify the IP address or domain name of a local IP interface, or an interface name (ie, isdn or ethernet ) to match only packets coming through this interface. Example commands for firewall This command will deny all packets from the host 129.97.34.• • • IP, ICMP, TCP, UDP It can reject the above traffic from a certain machine given its IP address It can reject the above traffic on a certain port. This is useful because one can configure firewall to selectively reject Telnet, Ftp, IRC, News, Web surfing, etc. Let us try to answer this question by picking up an example, hopefully this example can help you to understand the steps required in configuring a firewall better.
When the firewall is turned on, in order to have NAT you must enter the command : >config fire add divert ip from any to any via isdn 5.8 Connecting/Disconnecting ISDN connect Start a PPP or ML-PPP connection with the username. This is a manual method to make connection. The router will automatically extract the telephone number associated with the username and make an outgoing call to connect with the destination site.
log { display, clear, save } Display/Clear/Save the log to/from the flash. config tftp { disable, enable } Enable or disable tftp. TFTP (Trival File Transfer Protocol) allows the user to update the boot images and the configuration. TFTP is disabled by default. 5.10 Show Configuration show interface ether Display the information about the ethernet interface. show interface isdn Display the information about the ISDN interface. show ip arp Display the ARP (Address Resolution Protocol) table.
