CONFIG Commands

Specifies the type of protocol being redirected.

If you select

other

, specifies the number of the protocol you want to translate.

.

Specifies the IP address of the internal host to which traffic of the specified type

should be transferred.

Specifies the port number your Cayman Gateway should use when forwarding

traffic of the specified type. Under most circumstances, you would use the same

PPPoE Settings

You can use the following commands to configure basic settings, port authentica-

tion settings, and peer authentication settings for PPP interfaces on your Cayman

Gateway.

Enables or disables PPP over Ethernet on your 2E-H unit. You must enable PPPoE

before you can enter other PPP settings.

Appendix A

CONFIG Commands

Configuring Basic PPP Settings

Enables or disables PPP on the Cayman Gateway.

Specifies the Maximum Receive Unit (MRU) for the PPP interface. The

integer

argument can be any number between 128 and 2048.

Enables or disables LCP magic number negotiation.

Specifies whether you want the Cayman Gateway to compress the PPP Protocol

field when it transmits datagrams over the PPP link.

Specifies whether you want your Cayman Gateway to send LCP echo requests.

You should turn off LCP echoing if you do not want the Cayman Gateway to drop

a PPP link to a nonresponsive peer.

.

Specifies the maximum number of Configure-NAK messages the PPP module can

send without having sent a Configure-ACK message. The integer argument can

be any number between 1 and 20.

Specifies the maximum number of unacknowledged configuration requests that

your Cayman Gateway will send. The integer argument can be any number

between 1 and 10.

Specifies the maximum number of unacknowledged termination requests that

your Cayman Gateway will send before terminating the PPP link. The integer

argument can be any number between 1 and 10.

Many of these setting commands are designated as

BOTH

.

Note however:

For the 3220-H (DSL platform) you must identify the virtual PPP

interface [

vccn

], a number from 1 to 8.

This argument does not apply to the 2E-H platform.

Appendix A

CONFIG Commands

Specifies the number of seconds the Cayman Gateway should wait before retrans-

mitting a configuration or termination request. The integer argument can be any

number between 1 and 30.

Specifies whether a PPP connection is maintained by the Cayman Gateway when

it is unused for extended periods. If you specify

always-on

, the Cayman Gate-

way never shuts down the PPP link. If you specify

instant-on

, the Cayman

Gateway shuts down the PPP link after the number of seconds specified in the

time-out

setting (below) if no traffic is moving over the circuit.

If you specified a connection type of

instant-on

, specifies the number of seconds,

in the range 30-600, the Cayman Gateway should wait for communication activ-

ity before terminating the PPP link.

Configuring Port Authentication

You can use the following commands to specify how your Cayman Gateway

should respond when it receives an authentication request from a remote peer.

The settings for port authentication on the local Cayman Gateway must match

the authentication that is expected by the remote peer. For example, if the

remote peer requires CHAP authentication and has a name and CHAP secret for

the Cayman Gateway, you must enable CHAP and specify the same name and

secret on the Cayman Gateway before the link can be established.

Specifies whether CHAP authentication is enabled. CHAP authentication must be

enabled before you can enter other CHAP information. If CHAP is turned on, it

will be the first authentication method offered to the remote peer during link

negotiation.

If you turn port authentication off and peer authentication on, the PPP software

still uses the port authentication chap-name and pap-name for authentication. As

a result, the port authentication names for PAP and CHAP must be identical to the

peer names for your Cayman Gateway on the remote peer. If you do not config-

ure a chap-name or pap-name, then the authentication packets sent by the local

peer will have blank name values. This may cause authentication to fail for some

PPP implementations.

Appendix A

CONFIG Commands

Specifies the name the Cayman Gateway sends in a CHAP response packet. The

chap_name

argument is 1-64 alphanumeric characters. The information you

enter must match the CHAP username configured in the remote PPP peer's

authentication database.

Specifies the CHAP secret for CHAP authentication. The secret argument is 1-64

alphanumeric characters. The information you enter must match the CHAP secret

used by the PPP peer.

Specifies whether PAP authentication is enabled for a port. By default, PAP

authentication is turned off. PAP authentication must be enabled before you can

enter other PAP information. If you disable PAP authentication and save the modi-

fied configuration, your Cayman Gateway retains its PAP settings.

Specifies the name the Cayman Gateway sends in a PAP response packet. The

pap_name argument is 1- 64 alphanumeric characters. The information you enter

must match the PAP username configured in the PPP peer's authentication data-

base.

Specifies the password the Cayman Gateway sends when a PPP peer sends a PAP

authentication request. The password argument is 1-64 alphanumeric characters.

The information you enter must match the PAP password used by the PPP peer.

Appendix A

CONFIG Commands

Configuring Peer Authentication

You can specify that your Cayman Gateway will use PAP, CHAP, or both to authen-

ticate a remote peer as a PPP link is being completed. Perform the following steps

to specify how your Cayman Gateway should authenticate remote peers.

Specifies whether the Cayman Gateway will use CHAP to authenticate connec-

tions to PPP peers.

Specifies whether the Cayman Gateway will use PAP to authenticate connections

to PPP peers.

Specifies the hostname for an authorized PPP peer. The hostname argument is 1-

64 alphanumeric characters. The information you enter must match the user-

name that will be returned by the PPP peer when it is being authenticated.

Specifies the secret associated with a PPP peer. The secret argument is 1-64 alpha-

numeric characters. The information you enter must match the secret that will be

returned by the PPP peer when it is being authenticated.

Specifies the password associated with a PPP peer. The password argument is 1-

64 alphanumeric characters. The password you enter for that peer must match

the password that will be returned by the PPP peer when it is being authenti-

cated.
