Subscriber Configuration Mode Commands

ppp ▀

Cisco ASR 5x00 Command Line Interface Reference ▄

8331

enable

: The PDSN negotiates IPCP with the mobile.

passive

: The PDSN initiates IPCP only when the mobile sends an IPCP request.

keepalive

seconds

Default: 30
Specifies the frequency of sending the Link Control Protocol keepalive messages.

seconds

must be either 0

or an integer from 5 through 14400. The special value 0 disables the keepalive messages entirely.

min-compression-size

min_octets

Default: 128
Specifies the smallest packet (in octets) to which compression may be applied.

min_octets

must be an

integer from 0 through 2000.

mtu

max_octets

Default: 1500
Specifies the maximum transmission unit (MTU) [in octets] for packets.

max_octets

must be an integer

from 100 through 2000.

remote-renegotiation disconnect { always | nai-prefix-msid-mismatch }

Default: Disabled
Terminates the already established PPP sessions if they are renegotiated by the remote side by sending LCP
Conf-req/nak/ack. The following termination conditions are available:



always

: Automatically disconnects the session.



nai-prefix-msid-mismatch

: Disconnects the session only if the MSID of the session does not

match NAI-Prefix (prefix before “@” for the NAI). The configuration of the renegotiated (new) NAI
is used for the matching process.

Usage

Adjust packet sizes and compression to improve bandwidth utilization. Each network may have unique
characteristics such that determining the best packet size and compression options may require system
monitoring over an extended period of time.

Example

ppp data-compression protocols mode stateless

ppp mtu 500

no ppp data-compression protocols

no ppp keepalive
