This chapter describes the function and displays the syntax for Point-to-Point Protocol (PPP) Bandwidth Allocation Control Protocol (BACP) commands. For more information about defaults and usage guidelines, see the corresponding chapter of the Dial Solutions Command Reference.
To set PPP BACP call parameters, use the ppp bap call interface configuration command. To disable processing of a specific type of incoming connection, use the no form of this command.
ppp bap call {accept | request | timer seconds}| accept | Peer initiates link addition. This is the default. |
| request | Local side initiates link addition. |
| timer seconds | Number of seconds to wait between call requests the router sends, in the range 2 to 120 seconds. No default value is set. |
To enable PPP BACP callback and set callback parameters, use the ppp bap callback interface configuration command. To remove the PPP BACP callback configuration, use the no form of this command.
ppp bap callback {accept | request | timer seconds}| accept | Local router initiates link addition upon peer notification. |
| request | Local router requests that a peer initiate link addition. |
| timer seconds | Number of seconds to wait between callback requests the router sends, in the range 2 to 120 seconds. Disabled by default. |
To set parameters for removing links from a multilink bundle, use the ppp bap drop interface configuration command. To disable a specific type of default processing, use the no form of this command.
ppp bap drop {accept | after-retries | request | timer seconds}To specify the types of links that can be included in a specific multilink bundle, use the ppp bap link types interface configuration command. To remove a type of interface that was previously allowed to be added, use the no form of this command.
ppp bap link types [isdn] [analog]| isdn | (Optional) ISDN interfaces can be added to a multilink bundle. This is the default. |
| analog | (Optional) Asynchronous serial interfaces can be added to a multilink bundle. |
To set upper limits on the number of retransmissions for PPP BACP, use the ppp bap max interface configuration command. To remove any retry limit, use the no form of this command.
ppp bap max {dial-attempts number | ind-retries number | req-retries number || dial-attempts number | Maximum number of dial attempts to any destination number, in the range 1 to 3. The default is 1 dial attempt. |
| ind-retries number | Maximum number of retries of a call status indication message, in the range 1 to 10. The default is 3 indication retries. |
| req-retries number | Maximum number of retries for a particular request, in the range 1 to 5. The default is 3 request retries. |
| dialers number | Maximum number of free dialers logged, in the range 1 to 10. The default is 5 dialers. |
To validate peer requests to add or remove links against the current bundle load and the defined dialer load threshold, use the ppp bap monitor load interface configuration command. To specify that incoming link addition requests are not to be subject to the bundle load threshold, use the no form of this command.
ppp bap monitor loadTo specify a local telephone number that peers can dial to establish a multilink bundle, use the ppp bap number interface configuration command. To remove a previously configured number, use the no form of this command.
ppp bap number {default phone-number | secondary phone-number}| default phone-number | Primary (base) phone number for this interface, the number that can be used for incoming dial calls. |
| secondary phone-number | Telephone number for the second B channel. Applies only to BRI interfaces that have a different number for each B channel or to dialer interfaces that are BRIs. |
To specify nondefault timeout values for PPP BACP pending actions and responses, use the ppp bap timeout interface configuration command. To reset the response timeout to the default value, or to remove a pending timeout entirely, use the no form of this command.
ppp bap timeout {pending seconds | response seconds}| pending seconds | Number of seconds to wait before timing out pending actions, in the range 2 to 180 seconds. The default is 20 seconds. |
| response seconds | Number of seconds to wait for a response before timing out, in the range 2 to 120 seconds. The default is 3 seconds. |
To enable Multilink PPP (MLP) on an interface and, optionally, to enable dynamic bandwidth allocation, use the ppp multilink interface configuration command. To disable Multilink PPP or, optionally, to disable only dynamic bandwidth allocation, use the no form of this command.
ppp multilink [bap]| bap | (Optional) Specifies bandwidth allocation control negotiation and dynamic allocation of bandwidth on a link. |
| required | Enforces mandatory negotiation of BACP for the multilink bundle. The multilink bundle is disconnected if BACP is not negotiated. |
To display configured dynamic and static dialer maps and dynamically created PPP BACP temporary static dialer maps, use the show dialer map EXEC command.
show dialer mapTo display the configuration settings and run-time status for a multilink bundle, use the show ppp bap EXEC command.
show ppp bap {group [name] | queues}| group [name] | Displays information about all or, optionally, a specific BACP bundle group. |
| queues | Displays information about the BACP queues. |
To display bundle information for the Multilink PPP bundles, use the show ppp multilink EXEC command.
show ppp multilink
