Table 28: Differences in Lockout Operation for Dynamic PPPoE Configurations
Dynamic PPPoE over Static ATM 1483 Dynamic PPPoE over Static PPPoE
Encapsulation type lockout is enabled by default
with a lockout time range of 1–300 seconds. Encapsulation type lockout is disabled by
default.
PPPoE clients automatically inherit their lockout
setting from the lockout parameters configured
for the underlying static ATM 1483 subinterface
with the
auto-configure command.
Currently, the dynamic PPPoE interface layer must
be configured directly above the static ATM 1483
interface layer to support inheritance of lockout
parameters. For an illustration of dynamic PPPoE
over static ATM 1483 interface stacking, see Figure
46 on page 529.
You must explicitly configure encapsulation
type lockout for PPPoE clients with the
pppoe auto-configure command.
For more information about the benefits and operation of dynamic encapsulation
type lockout, see “Encapsulation Type Lockout” on page 525. In particular, see
“Guidelines for Configuring Encapsulation Type Lockout” on page 527 for information
about the rules that apply when you configure the lockout time. These rules are
common to both dynamic PPPoE over static PPPoE configurations and dynamic
PPPoE over static ATM 1483 configurations.
Configuration Tasks
Configuring dynamic encapsulation type lockout for PPPoE clients includes the
following tasks:
■
Configuring and verifying lockout for PPPoE clients
■
Clearing the lockout condition for a specific PPPoE client
Configuring and Verifying Lockout for PPPoE Clients
To configure and verify encapsulation type lockout for a PPPoE client:
1.
Configure the underlying physical interface.
For example, the following commands configure a static ATM 1483 subinterface
and corresponding ATM PVC.
host1(config)# interface atm 3/0
host1(config-if)# interface atm 3/0.101
host1(config-subif)# atm pvc 10 10 20 aal5snap
2.
Create a static PPPoE major interface.
host1(config-subif)# encapsulation pppoe
3.
Configure the PPPoE major interface to detect and accept dynamic PPPoE
subinterfaces. Use the
lockout-time keyword to configure a nondefault lockout
