PVID Type a PVID (Port VLAN ID) to assign to untagged frames received on
this channel.
Note: Make sure the VID is not already used for multicast VLAN
or TLS PVC.
Priority Use the drop-down list box to select the priority value (0 to 7) to add
to incoming frames without a (IEEE 802.1p) priority tag.
AC Name This field is optional. Specify the hostname of a remote access
concentrator if there are two access concentrators (or BRAS) on the
network or if you want to allow PAE translation to the specified access
concentrator. In this case, the IES-1248-51V checks the AC name field
in the BRAS's reply PDU. If there is a mismatch, the IES-1248-51V
drops this PDU. (This is not recorded as an PPPoE AC System Error
in the PPPoA to PPPoE Status screen, however.)
Service Name This field is optional. Specify the name of the service that uses this
PVC. This must be a service name that you configure on the remote
access concentrator.
Hellotime Specify the timeout, in seconds, for the PPPoE session. Enter 0 if there
is no timeout.
Apply Click this to add or save channel settings on the selected port.
This saves your changes to the IES-1248-51V’s volatile memory. The
IES-1248-51V loses these changes if it is turned off or loses power, so
use the Config Save link on the navigation panel to save your
changes to the non-volatile memory when you are done configuring.
Cancel Click Cancel to start configuring the screen again.
Show Port Select which ADSL port(s) for which to display PPPoA to PPPoE
conversion settings.
Index This field displays the number of the PVC. Click a PVC’s index number
to open the screen where you can look at the current status of this
PPPoA-to-PPPoE conversion. (See
Section 31.3 on page 241 .)
Note: At the time of writing, you cannot edit the VPI and VCI. If
you want to change them, add a new PVC with the desired
settings. Then, delete any unwanted PVCs.
Port This field displays the number of the ADSL port on which the PVC is
configured.
VPI/VCI This field displays the Virtual Path Identifier (VPI) and Virtual Circuit
Identifier (VCI). The VPI and VCI identify a channel on this port.
PVID This is the PVID (Port VLAN ID) assigned to untagged frames or
priority frames (0 VID) received on this channel.
Priority This is the priority value (0 to 7) added to incoming frames without a
(IEEE 802.1p) priority tag.
Hellotime This field displays the timeout for the PPPoE session, in seconds.
DS / US VC Profile This shows which VC profile this channel uses for downstream traffic
shaping. The VC profile for upstream policing also displays if the
channel is configured to use one.
