Router(config-if)# ppp max-failure 100
Router(config-if)# ppp timeout retry 5
Router(config-if)# keepalive 30
Router(config-if)# no ip address

Router(config-if)# ppp authentication chap
Router(config-if)# ppp multilink
Router(config-if)# exit
Adding a Serial Member Link to an MLP Bundle
You can configure up to 10 serial member links per MLP bundle. When adding T1 member links, add
only full T1 interfaces. If the interface you add to the MLP bundle contains information such as an IP
address, routing protocol, or access control list, the router ignores that information. If you remove the
interface from the MLP bundle, that information becomes active again.
To add serial member links to an MLP bundle, enter the following commands beginning in global
configuration mode:
Command Purpose
Step 1
Router(config)# interface serial
slot/module/port.channel:controller-number
Specifies the interface that you want to add to the MLP
bundle. Enters interface configuration mode.
slot/module/port identifies the line card. The slashes are
required.
channel: is the channel group number. The colon is required.
controller-number is the member link controller number.
Step 2
Router(config-if)# hold-queue length {in |
out}
Limits the size of the IP output queue on an interface. We
recommend that you configure this command on all physical
interfaces.
length is a number that specifies the maximum number of
packets in the queue. Valid values are from 0 to 4096. We
recommend 4096 packets for all line cards. By default, the
input queue is 75 packets and the output queue is 40 packets.
in specifies the input queue.
out specifies the output queue.
Step 3
Router(config-if)# ppp max-configure retries
Specifies the maximum number of configure requests to
attempt before stopping the requests due to no response.
retries specifies the maximum number of retries. Valid values
are from 1 to 255. The default is 10 retries. We recommend
110 retries.
