Making Frame Relay Connections

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. For important information about Y-cable redundancy on

 

a UFM-U, see the description in the UFM-U portion of the Cisco IGX 8400 Series

 

Reference.

Step 6

Activate the ports using the upfrport command.

Step 7

Configure the port for DCE or DTE mode, speed, clocking, LMI type, and so on, by using

 

the cnffrport command. Alternatively, you can keep the default parameters. If you plan

 

to bundle connections, use cnffrport to set the Port ID to the DLCI planned for the

 

near-end connections before you add the bundled connections. The PortID is optional for

 

non-bundled connections. Note that cnfport functions the same for Frame Relay as

 

cnffrport.

Step 8

Add connections by using the addcon command. Adding connections requires the slot

 

number, logical port number, and DLCI for each end of the connection. Frame Relay is a

 

purchased option. If you attempt to add connections but the system display states that

 

Frame Relay is not available, call the TAC through Customer Engineering.

 

If you do not know the Frame Relay class intended for entry with the addcon command,

 

determine which Frame Relay class number to use. Use the Display Frame Relay Classes

 

(dspfrcls) command to see the parameters that each class specifies. To modify parameters

 

in a class, use Configure Frame Relay Class ( cnffrcls).

Step 9

Optionally—for an individual connection— you can configure bandwidth parameters or

 

enable ForeSight (if purchased) by using Configure Frame Relay Connection ( cnffrcon).

Optionally, you can set the channel priority by using the cnfchpri command. Normally, the system-default priority is adequate.

Commands for T1/E1 Frame Relay

To specify logical ports on a T1 or E1 interface, use addfrport. The addfrport command assigns a logical port number to a physical line and a range of 1 or more DS0s/timeslots. Use the logical port number to activate a port (upfrport), add connections (addcon), or display statistics (dspportstats). For example, after you add logical port 14.60 2.1-24 with addfrport, you up this logical port by entering “ upfrport 14.60.” The maximum number of logical port numbers on a UFM-C is 250. Use dspfrport to display logical ports.

Deleting a Frame Relay Port

Delete a logical port by executing the delfrport command. Executing delfrport dissolves any groups of DS0s/timeslots and unassigns all DS0s/timeslots on the logical port. (Note that, before you delete a Frame Relay port, you must delete any connections on the port with delcon.) After deleting a logical port with delfrport, you can de-activate the physical port with dnport.

Setting Up Frame Relay on an FRM

Four types of interfaces are available for the FRM. The back cards have the following terminations:

The FRI-T1 has a female, subminiature DB-15.

The FRI-E1 has a single 120-ohm, DB-15 connector for a balanced termination and two, 75-ohm BNC connectors for coaxial cables for an unbalanced termination. All connectors are female.

FRI-V.35 has standard 34-pin female MRAC type connectors with a standard V.35 cable.
