Creating ATM Links within Virtual Switch Ports

4-18
An ATM Link is defined within a VSP and it groups PVCs that end at
the same destination. An ATM Link is the equivalent of a LANE
ATM destination.
Each ATM link has space for eight PVC entries to support priority
based QoS in RFC1483 mode. After the PVCs have been defined in
the ATM Link, you should make sure that each Ethernet priority is
mapped to a PVC. As Ethernet traffic is sent, the ATM Uplink
module will forward the various priority frames down the
appropriate PVC. If you fail to map an Ethernet priority, traffic sent
at that priority will be dropped.
Each PVC in the ATM Link should terminate at the same remote
interface. However, there is no enforcement of this restriction and
you may configure the ATM Link so frames are forwarded to
different remote interfaces based on priority. This is not
recommended.
If you are configuring two links that connect directly to each other,
you must ensure that the same VP/VC numbers are used for the
PVCs.
Each ATM Uplink module supports a maximum of 16,000 ATM
links.
This section provides the information you need to configure ATM
links for your virtual switch ports. It contains the following
information:

Deleting ATM Links for Virtual Switch Ports
To create an ATM link:
1. Select Modules & Ports > Configuration from the Web
Agent. The Module Information dialog box opens
(Figure 64).
