Configuring Async Pads 13-21
The virtual connection will be established when the nodes at both ends undergo re-
IPL. If you want to establish a connection without disrupting node operation, create
an identical PVC on line. Press
[D]
at the Operations Menu (or
[B], [D]
from the Main
Menu) and enter the requested information, noting the values in Table 13-5 . (This is
described in greater detail under “ Creating/Deleting a PVC On Line ” (on page 13-22.)
PVC Parameters
Explanations follow the table. Note that parameters labeled in a record as
Primary
or
Secondary
identify each end of the connection. (It does not matter which end is
which.)
1
Logical channels must be lower than the lowest LCNs assigned to any subscribers on the
ports in a PVC record.
2
16, 32, 64,128, 256, 512, 1024, 2048, or 4096 . Cannot be greater than the smaller
Maxim um Packet Size specified in the Port records for both ends of the connection.
3
Cannot be greater than the smaller Maximum Window Size specified in the Port records
for both ends of the connection.
Bandw. Alloc. Group
is a method of prioritizing outgoing traffic over trunks. Each IP and IPX network
interface, SVC Subscriber, and PVC is assigned to a bandwidth allocation group
defined by a
Percent of Bandwidth
value (
1–100
) and a
Priority
(
0–9
) specified in the
Network Defaults file. (See " Bandwidth Allocation Groups for Trunks " on page 4-8.)
Primary/Secondary Logical Channel
is a logical link between the node and each subscriber. The physical line may have a
number of logical channels. An LCN assigned to a port in a PVC record must be lower
than the lowest LCN specified for any SVC subscriber on the same port.
Primary/Secondary Subscriber Name
identifies the subscribers to the console operator. The FRX8000 software does not use
this information.
