Setting Up FR Ports and Connections (UFM)
This section outlines the steps for setting up and deleting FR ports and adding connections.
Use either a Cisco WAN Manager workstation an IGX control terminal to do the following tasks. For
detailed command descriptions, see the Cisco WAN Switching Command Reference.
Step 1 If necessary, use the dspcds command to verify the correct back card and front card. (Use the vt
command to access other nodes.) The dspcds output shows any mismatch between the front card and the
back card.
Step 2 If the card is a UFM-C, “up” (or activate) each line with the upln command. The range of lines for a
UFM-4C is 1 to 4. The range of lines for a UFM-8C is 1 to 8. A UFM-U does not require activation with
the upln command.
Step 3 If the card is a UFM-C, assign logical FR ports to individual physical lines by using the addport
command. An optional command you can use for a UFM-C either before or after is the cnfln command.
Step 4 If the card is a UFM-U, use the cnfmode command to configure the mode of the card if you do not use
the default of mode 1. You must understand the ramifications of this step before you use cnfmode. If
you do not understand the modes of the UFM-U, see the “Universal Frame Module” section on
page 2-50.
Step 5 For optional Y-cable redundancy, configure the two cards by using the addyred command. For Y-cable
redundancy on a HSSI card, you must use port 1 of the cards for the primary and redundant ports.
Step 6 Activate a FR port with the upport command. Use the cnfport command to specify the FR parameters
for the FR service.
Step 7 Use the dspcls command to view the existing FR classes. Decide on a class if a suitable class exists,
otherwise create a suitable class using the cnffrcls command. Use the class number in the addcon
command.
Step 8 Use the vt command to access the node at the remote end of the proposed FR connection, then repeat
steps 1 and 2.
Step 9 Use the addcon command on the local node to add the FR connection.
Step 10 (Optional) Use the cnfchutl command to enter the expected channel utilization of an FR circuit into the
system. This command helps the system allocate the proper bandwidth to the circuit.
Step 11 (Optional) Use the cnfchpri to assign a high priority to a circuit or to re-assign a high priority circuit to
low priority.
Note An FR connection has either low or high priority. The default is low priority.
Step 12 Configure the port for DCE or DTE mode, speed, clocking, LMI type, and so on, by using the cnfport
command. Alternatively, you can keep the default parameters.
Step 13 Add connections by using the addcon command. Adding connections requires the slot number, logical
port number, and DLCI for each end of the connection. FR is a purchased option.
Step 14 (Optional) For an individual connection, you can configure bandwidth parameters or enable ForeSight
(if purchased) by using the cnffrcon command.
