Using the Command Line Interface

December 2000

set ip ip-ppp vccn peer-address ip_address

Specifies the IP address of the peer on the other end of the PPP link. 
If you specify an IP address other than 0.0.0.0, your Cayman 3220-H 
will not negotiate the remote peer's IP address. If the remote peer 
does not accept the address in the 

 argument as its IP 

address (typically because it has been configured with another IP 
address), the link will not come up.

The default value for the 

 argument is 0.0.0.0, which 

indicates that the virtual PPP interface will accept the IP address 
returned by the remote peer. If you enter 0.0.0.0, the peer system 
must be configured to supply this address.

set ip ip-ppp vccn restriction 

{ admin-disabled | admin-only | none }

Specifies restrictions on the types of traffic the Cayman 3220-H 
accepts over the PPP virtual circuit. For security reasons, the 

admin-disabled

 argument is the default; it means that router traffic 

is accepted but that administrative commands are ignored. The 

admin-only 

argument means that router traffic is ignored but that 

administrative commands are accepted. The 

none

 argument means 

that all traffic is accepted. 

set ip ip-ppp vccn addr-mapping { on | off }

Specifies whether you want the Cayman 3220-H to use network 
address translation (NAT) when communicating with remote 
routers. Network address translation lets you conceal details of your 
network from remote routers. By default, address mapping is turned 
on.

For more information on network address translation, see “About 
Network Address Translation” on page C-2. 

set ip ip-ppp vccn vj-compression { on | off }

Specifies whether you want to negotiate Van Jacobson header 
compression for asynchronous PPP links. By default, TCP/IP header 
compression is turned on.
