Administrator
Adds a PVC cross-connect to the switch, which sets up a
virtual circuit on the specified ports.
When referring to ports, the terms “low” and “high” refer
to the direction of data flow, inbound (forward) and
outbound (backward). Thus, forward is the connection
from the low port to the high port and backward is the
connection from the high port to the low port.
Before adding a PVC you can define the traffic descriptor
for both the forward and backward directions using
add
trafficdescriptor .
delete pvc [LowPort] <lowport>
[LowVPI] <lowvpi>
[LowVCI] <lowvci>
[HighPort] <highport>
[HighVPI] <highvpi>
[HighVCI] <highvci>
Administrator
Removes a PVC cross-connect based on a cross-connect
ID or a cross-connect sub ID. The sub IDs identify a leaf
in PMP connections. Enter show pvc before this
command to display the cross-connect ID and sub IDs.
activate pvc [LowPort] <lowport>
[LowVPI] <lowvpi>
[LowVCI] <lowvci>
[HighPort] <highport>
[HighVPI] <highvpi
[HighVCI] <highvci>
Administrator
Activates a PVC. This is applicable only if the PVC was
deactivated by the Administrator. In a PMP PVC, this
command must be repeated for every leg of the PVC.
deactivate pvc [LowPort] <lowport>
[LowVPI] <lowvpi>
[LowVCI] <lowIPvci>
[HighPort] <highport
[HighVPI] <highvpi>
[HighVCI] <highvci>
Administrator
Deactivates a PVC. This is applicable only if the PVC is
operational and it must be made inactive. However, this
command is not persistent. If you reboot the switch, the
PVC becomes active again.
show pvc [Port Number] <portnumber>
[CrossConId] <crossconnectid>
All
Displays all PVCs configured for the specified port. It
has two modes of printing—detailed <
/d > and summary
< /s >. The < /d > option flag displays detailed
information; the < /s > flag displays summarized
information. Every PVC is assigned a unique number,
called the cross-connect id.The 40-second interval is the
maximum duration for holding these counters without
overflowing them.Special PVCs are signaling and ILMI.
They use VCI 5 and 16, respectively.
