IBM SC30-3681-08 manual Receive clock lines. The range is 2400 to 2 048 000 bps, Interface

Con®guring PPP Interfaces (Talk 6)

hdlc speed value

For internal clocking, this command speci®es the speed of the transmit and

receive clock lines. The range is 2400 to 2 048 000 bps.

For external clocking, this command does not affect the hardware but it sets

the speed of some protocols, such as IPX, used to determine the routing

parameters. In these cases, set the speed to match the actual line speed. If

speed is not con®gured or is set to 0, the protocol assumes a speed of

1 000 000 bps. The maximum speed that can be con®gured if external

clocking is used can be 6 312 000 bps. If you want to use a line speed

greater than 2048000, you can only do this on:

v interface 1.

v port 1 of a 4-port WAN concentration adapter.

v ports 1 and 5 of an 8-port WAN concentration adapter.

The other WAN ports must be clocked at 64 Kbps or less.

Example: set hdlc speed 56000

hdlc transmit-delay value

Sets the number of ¯ags sent between frames. The purpose of this

command is to slow the serial line so that it is compatible with older, slower

serial devices at the other end.

The range is 0 to 15. The default is 0.

Example: set hdlc transmit-delay 15

ipcp Sets all Internet Protocol Control Protocol options for that link.

Example:

set ipcp

IP COMPRESSION [yes]:

Number of Slots: [16]?

Send our IP address [yes]:

Note: unnumbered interface addresses will not be sent.

Interface remote IP address to offer if requested (0 for none) [0.0.0.0]? 10.0.0.3

IPCP compression

Selects whether or not the PPP handler will accept compressed IP

data. PPP supports Van Jacobson (VJ) TCP/IP header compression

as described in RFC 1144. You should enable this option when the

point-to-point link is running at a low baud rate.

Setting this value to yes enables the compression option. Setting

this value to no disables the option. The default setting is no.

Slots Sets the number IP headers that are saved for referential purposes

when determining the type of compression that is enabled. The

range is 1 to 16. The default is 16.

Send Our IP address

Speci®es whether or not to send the local IP address to the remote

end of the link. You should set this option to yes if the other end of

the link requires the IP address.

If this value is set to yes, IPCP will send the IP address of the PPP

interface, if the interface is con®gured with a numbered IP address,

(that is, the address does not begin with 0). If this option is set to

no and the peer sends us a Con®gure NAK with 0.0.0.0 for the IP

Address option, the 2210 will respond with the address of the PPP

interface if it is con®gured with a numbered address.
