LABEL DESCRIPTION
xDSL Port Setup Click xDSL Port Setup to go to the screen where you can configure
DSL port settings (see
Section 16.7 on page 121 ).
PPVC Setup Click PPVC Setup to open the PPVC Setup screen where you can
configure priority PVC settings for the DSL ports (see
Section 16.11
on page 134 ).
Port Use this drop-down list box to select a port for which you wish to view
or configure settings. This field is read-only once you click on a port
number below.
Super Channel The IES-1248-51V forwards frames belonging to VLAN groups that
are not assigned to specific channels to the super channel.
Enable the super channel option to have this channel forward frames
belonging to multiple VLAN groups (that are not assigned to other
channels).
The super channel functions in the same way as the channel in a
single channel environment.
VPI Type the Virtual Path Identifier for a channel on this port.
VCI Type the Virtual Circuit Identifier for a channel on this port.
DS VC Profile Use the drop-down list box to select a VC profile to use for this
channel’s downstream traffic shaping.
US VC Profile Use the drop-down list box to select a VC profile to use for this
channel’s upstream traffic. The IES-1248-51V 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.
PVID Type a PVID (Port VLAN ID) to assign to untagged frames received on
this channel.
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. An asterisk
(*) denotes a super channel.
Add
Apply
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-1248-51V’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 the number of an ADSL port for which to display VC settings
(or display all of them).
