DESCRIPTION
Type the Virtual Circuit Identifier for a channel on this port.
Use the drop-down list box to select a VC profile to use for this channel's
downstream traffic shaping.
Use the drop-down list box to select a VC profile to use for this channel's
upstream traffic. The IES-1248 does not perform upstream traffic policing if you
do not specify an upstream VC profile.
Note: Upstream traffic policing should be used in conjunction with
the ATM shaping feature on the subscriber's device. If the
subscriber's device does not apply the appropriate ATM
shaping, all upstream traffic will be discarded due to
upstream traffic policing.
Type a PVID (Port VLAN ID) to assign to untagged frames received on this
channel.
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. An asterisk (*) denotes a super
channel.
Click this to add or save channel settings on the selected port. (The name of the
button depends on whether or not you have clicked on a PVC number in the
Index column.)
This saves your changes to the IES-1248's volatile memory. The IES-1248
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.
Click Cancel to start configuring the screen again.
Select the number of an ADSL port for which to display VC settings (or display
all of them).
This field displays the number of the PVC. Click a PVC's index number to use
the top of the screen to edit the PVC.
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 you can delete any unwanted PVCs.
This field displays the number of the ADSL port on which the PVC is configured.
This field displays the Virtual Path Identifier (VPI) and Virtual Circuit Identifier
(VCI). The VPI and VCI identify a channel on this port.
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.
This is the PVID (Port VLAN ID) assigned to untagged frames or priority frames
(0 VID) received on this channel. An asterisk (*) denotes a super channel.
This is the priority value (0 to 7) added to incoming frames without a (IEEE
802.1p) priority tag. An asterisk (*) denotes a super channel.
