Use to specify the keepalive timeout value in the range 10–64800 seconds. If issued
in the context of an individual interface, the command affects only that interface. If
issued in the context of an MLPPP bundle, the command affects all MLPPP link
interfaces that are member links of that bundle.
When the keepalive timer expires, the interface always sends an LCP echo request,
regardless of whether the peer is silent.
When the keepalive interval is 30 seconds (the default), a failed link is detected between
90 and 120 seconds after failure.
Use ppp keepalive without a value to restore the default, 30 seconds.
Example
host1(config-if)#ppp keepalive 50
Use the no version to disable keepalive.
See ppp keepalive.
Use to enable PPP packet or state machine logging on any dynamic interface that uses
the profile being configured. Specify one of the following keywords:
pppPacket—Enables PPP packet logging
pppStateMachine—Enables PPP state machine logging
Example
host1(config-profile)#ppp log pppPacket
NOTE: This command is equivalent to the log severity debug pppPacket and log
severity debug pppStateMachine commands.
Use the no version to disable packet or state machine logging.
See ppp log.
Use to disable negotiation of the local magic number. If issued in the context of an
individual interface, the command affects only that interface. If issued in the context
of an MLPPP bundle, the command affects all MLPPP link interfaces that are member
links of that bundle.
Issuing this command prevents the router from detecting loopback configurations.
Example
host1(config-if)#ppp magic-number disable
