PPPoE Client Configuration Commands 259
no-hostuniq: The call originated from PPPoE Client does not carry the Host-Uniq
field. By default, no no-hostuniq parameter is configured, i.e. PPPoE session works
in permanent online mode by default.
idle-timeout seconds: Idle time of PPPoE session in seconds, and its value ranges
from 1 to 65535. If the parameter is not configured, PPPoE session will work in
permanent online mode. Otherwise, it will works in packet trigger mode.
queue-length packets: packet number cached in the system before PPPoE session
is established, its value ranges from 1 to 100.Only after idle-timeout is configured
will the parameter be enabled. By default, packets is 10.
Description
Using the pppoe-client command, you can establish a PPPoE session and specify
the Dialer Bundle corresponding to the session. Using the undo pppoe-client
command, you can delete a PPPoE session.
By default, no PPPoE session is configured.
Multiple PPPoE sessions can be configured at one Ethernet interface, i.e. one
Ethernet interface might simultaneously belong to multiple Dialer Bundles.
However, one Dialer Bundle only has one Ethernet interface. PPPoE session and
Dialer Bundle are one-to-one. If the Dialer Bundle at a certain Dialer has had one
Ethernet interface used by PPPoE, any other interfaces cannot be added to this
Dialer Bundle. Likewise, if Dialer Bundle has had interfaces other than the PPPoE
Ethernet interface, this Dialer Bundle can also not be added to the Ethernet
interface used by PPPoE Client.
When PPPoE session works in permanent online mode, and the physical lines go
UP, the Router will immediately initiate PPPoE call to establish PPPoE session. This
PPPoE connection will exist constantly unless users use the command undo
pppoe-client to delete PPPoE session. When PPPoE session works in packet trigger
mode, the Router will not initiate PPPoE call to establish PPPoE session unless it has
data to transmit. If there is no data transmission on the PPPoE link within seconds,
the Router will automatically terminate PPPoE session. Only after it has new data
to transmit, PPPoE session will be re-established.
For the related command, see reset pppoe-client.
