This chapter describes DIALs configuration and operational commands. It includes the following sections:
Use the following procedure to access the global configuration process.
* talk 6
Config>
After you enter the talk 6 command, the CONFIG prompt (Config>) displays on the terminal. If the prompt does not appear when you first enter configuration, press Return again.
Table 56. DIALs Global Configuration Commands
| Command | Function |
|---|---|
| ? (Help) | Displays all the commands available for this command level or lists the options for specific commands (if available). See "Getting Help". |
| Add | Adds a (Dynamic Host Configuration Protocol) DHCP server to the list of DHCP servers or adds an IP address pool. |
| Delete | Deletes a DHCP server from the list or removes a block of addresses from an IP address pool |
| Disable | Disables IP address assignment methods, dial-out protocols, multi-chassis MP, SPAP Banner, and Dynamic DNS. |
| Enable | Enables various methods of IP address assignments, dial-out protocols, multi-chassis MP, SPAP Banner, and Dynamic DNS. |
| List | Lists the Global DIALs parameters and their values. |
| Set | Sets time-allowed, dhcp gateway address, NetBIOS Name Server addresses, locally assigned MAC addresses, Virtual Connections (VC) Dynamic Name Server addresses, dial-out inactivity timer, and dial-out server-name. |
| Exit | Returns you to the previous command level. See "Exiting a Lower Level Environment". |
Use the add command to add a new Proxy DHCP server to a list of servers or to add an IP pool of addresses.
The proxy DHCP server list contains the IP addresses of the DHCP servers that will, in turn, lease IP addresses to the dial-in clients. Multiple servers may be added for redundancy. The maximum number of servers is 20.
The IP address pool feature provides a method by which the router may retrieve an IP address from a locally defined pool of addresses to a dial-in client. The client may use this address for the duration of the connection to the router. A pool consists of one or more blocks of IP addresses. The maximum number of blocks is 20. Each of these blocks is defined by a base IP address and the number of addresses in the block. The addresses in each block are ascending and contiguous, starting with the base address.
Syntax:
Example :
DIALs Config> add dhcp-server DIALs Proxy DHCP server address [0.0.0.0]? 10.0.0.1
Example:
DIALs Config> add ip-pool
Base address []? 192.1.100.18
Number of addresses [1]? 57
DIALs config>add ip-pool
Base address []? 192.2.200.1
Number of addresses [1]? 250
DIALs config>list ip-pools
Configured IP address pools:
Base Address Last Address Number
------------ ------------ ------
192.1.100.18 192.1.100.74 57
192.2.200.1 192.2.200.250 250
Use the delete command to delete an existing Proxy DHCP server from the list of servers or to remove a block of addresses from the IP address pool.
Syntax:
Example:
DIALs Config> delete dhcp-server Enter the address to be deleted [0.0.0.0]? 10.0.0.1
Example:
DIALs Config> delete ip-pool Base IP address of the block to be removed []? 192.2.200.1
Use the disable command to disable an IP address assignment method, dial-out protocols, SPAP Banner, and Dynamic DNS.
Syntax:
To disable both types of clients you must enter the disable dial-out command for each type. Disabling both types of clients disables dial-out on the 2212.
See "Server Provided IP Addresses" for additional information about assignment techniques.
| Note: | Entering a \n will force a new line character in the banner displayed at the client. |
Use the enable command to enable IP address assignment, dial-out protocols, SPAP Banner, and Dynamic DNS.
Syntax:
See "Server Provided IP Addresses" for additional information about assignment techniques.
Use the list command to display the current configuration. The DHCP state and lease times can be monitored for each net from the Point-to-Point console. See the listipcp command in the Access Integration Services Software User's Guide for an example.

Syntax:
If the DHCP server is not on a directly attached LAN interface, then you must configure this address to the address of one of the LAN interfaces that has IP connectivity to the DHCP server. See "Dynamic Host Configuration Protocol (DHCP)" and the definition of "giaddr" in RFC 1541 for more information.

Monitoring dial-in interfaces is the same as monitoring other PPP dial circuits. For details, see "Configuring and Monitoring Point-to-Point Protocol Interfaces" in the Access Integration Services Software User's Guide .
Table 59 lists the commands available when monitoring dial-out
interfaces.
Table 59. dial-out Interface Monitoring Commands
| Command | Function |

Use the clear command to reset the statistics for the number of octets received and transmitted by this interface.
Syntax:
clear Statistics reset.
Use the list command to display current state of the dial-out interface. The list command always displays the current state of the dial-out net, the time since the state change, and the number of bytes received and transmitted.
Syntax:
list Dial-out Settings for current session: Dial-out state is DOWN Time since change = 52 minutes and 34 seconds Dial-out Octets transmitted = 0 Dial-out Octets received = 0 Session down, no valid settings
| Note: | When a client connects to a dial-out port using Telnet, no user name is present because the server did not perform any authentication. |
Example for active interface:
