auto-configure
528
Use to configure a static ATM 1483 subinterface to support a dynamic interface.
Specifies the types of dynamic encapsulation that the subinterface detects and accepts.
This command creates the layers above ATM 1483 dynamically.
You can enter the command repetitively to support multiple dynamic interface types.
Select the dynamic next upper-interface type from these options: bridgedEthernet, ip,
ppp, or pppoe.
Encapsulation type lockout is performed on a per-encapsulation-type basis for each
subinterface. An encapsulation type not configured for autodetection with the
auto-configure command is automatically locked out. The lockout temporarily prevents
the static ATM 1483 subinterface from detecting, accepting, and creating the
encapsulation type until the lockout time expires.
Use the lockout-time keyword to set the minimum lockout time and maximum lockout
time, each of which can be in the range 1–86400 seconds (24 hours).The default range
is 1–300 seconds (5 minutes).
Use the none keyword to disable lockout for the specified encapsulation type.
NOTE: Disabling lockout can result in undesirable CPU loading; we
recommend that you not disable lockout for general use. At a minimum,
use the default lockout time.
For information about the rules that apply when you configure the lockout time for
dynamic encapsulation type lockout, see "Guidelines for Configuring Encapsulation
Type Lockout for PPPoE sessions" on page 523.
Example 1—Enables autodetection for the PPPoE encapsulation type using the default
lockout time range, 1–300 seconds
host1(config-subif)#auto-configure pppoe
Example 2—Enables autodetection for the PPP encapsulation type using a nondefault
lockout time range, 5–60 seconds
host1(config-subif)#auto-configure ppp lockout-time 5 60
Example 3—Disables encapsulation type lockout for the PPPoE encapsulation type
host1(config-subif)#auto-configure pppoe lockout-time none
Example 4—Either command reenables encapsulation type lockout for the PPPoE
encapsulation type using the default lockout time range
host1(config-subif)#auto-configure pppoe
host1(config-subif)#no auto-configure pppoe lockout-time
Example 5—Permanently locks out the PPP encapsulation type until the auto-configure
ppp command is issued
host1(config-subif)#no auto-configure ppp
