Cayman 3220-H User’s Guide Using the Command Line Interface

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 ip_address 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 ip_address 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.
