Line Service Commands

ipaddr-neg

Specifies whether or not IP address negotiation will take place. IP address negotiation is
where the IOLAN allows the remote end to specify its IP address. The default value is

Off

. When

On

, the IP address specified by the remote end will be used in preference to

the

Remote IP Address

set for a

Line

. When

Off

, the

Remote IP Address

set for the

Line

will be used.

ipv6-global-network-prefix

You can optionally specify an IPv6 global network prefix that the IOLAN will advertise
to the device at the other end of the PPP link. Enter the IPv6 network prefix in the

aaaa:bbbb:cccc:dddd::

format.

ipv6-local-interface

The local IPv6 interface identifier of the IOLAN end of the PPP link. For routing to
work, you must enter a local IP address. Choose an address that is part of the same
network or subnetwork as the remote end. Do not use the IOLAN’s (main) IP address in
this field; if you do so, routing will not take place correctly. The first 64 bits of the
Interface Identifier must be zero, therefore, ::abcd:abcd:abcd:abcd is the expected
format.

ipv6-remote-interface

The remote IPv6 interface identifier of the remote end of the PPP link. Choose an
address that is part of the same network or subnetwork as the IOLAN. If you set the

PPP

parameter

IP Address Negotiation

to

On

, the IOLAN will ignore the remote IP

address value you enter here and will allow the remote end to specify its IP address. If
your user is authenticated by RADIUS and the RADIUS parameter

Framed-Interface-ID

is set in the RADIUS file, the IOLAN will use the value in the

RADIUS file in preference to the value configured here. The first 64 bits of the
Interface Identifier must be zero, therefore, ::abcd:abcd:abcd:abcd is the expected
format.

lipaddr

The IPV4 IP address of the IOLAN end of the PPP link. For routing to work, you must
enter a local IP address. Choose an address that is part of the same network or
subnetwork as the remote end; for example, if the remote end is address
192.101.34.146, your local IP address can be 192.101.34.145. Do not use the IOLAN’s
(main) IP address in this field; if you do so, routing will not take place correctly.

magic-neg

Determines if a line is looping back. If enabled (

On

), random numbers are sent on the

link. The random numbers should be different, unless the link loops back. The default is

Off

.

mru

The Maximum Receive Unit (MRU) parameter specifies the maximum size of PPP
packets that the IOLAN’s port will accept. Enter a value between 64 and 1500 bytes; for
example, 512. The default value is

1500

. If your user is authenticated by the IOLAN,

the

MRU

value will be overridden if you have set a

Framed MTU

value for the user. If

your user is authenticated by RADIUS and the RADIUS parameter

Framed-MTU

is set

in the RADIUS file, the IOLAN will use the value in the RADIUS file in preference to
the value configured here.

nak-retry

The maximum number of times a

configure NAK

packet will be re-sent before the

link is terminated.
