Adding a Virtual Circuit

Data virtual circuits and their

DLCI

s are normally learned through status messages with the

Frame Relay network. However, it may be convenient to pre-configure these virtual circuits
before connecting to a live network. In such a case you will need to use the

fradd

command

to set parameters for the virtual circuit. The information for the virtual circuit will be stored in
the

WSX

database. This method of configuration is different than using the

frmodify

command,

which changes virtual circuit parameters after the circuit has been learned from the network
or configured through

fradd

To set up a data virtual circuit, enter the following command

fradd //

where

is the slot number where the

WSX

board is located,

is the port number on

the

WSX

board, and

is the number used to identify the virtual circuit that you want to

add. For example, if you wanted to add

DLCI

32 on Port number 1 of the

WSX

board in slot 2,

you would enter

fradd 2/1/32

fra 2/1/32

A screen similar to the following displays:

Adding Frame Relay port for Slot: 2, Port: 1 Dlci: 32.

1) Administrative State ..................................................... = UP

{(U)p, (D)own}

2) Committed Information Rate (CIR) in BPS ..................... = 0

{0 through line speed in BPS}

3) Committed Burst Rate (Bc) in bits ................................ = 0

{0 through positive number in bits}

4) Excess Burst Rate (Be) in bits ...................................... = 0

{0 through positive number in bits}

5) Compression Administrative Status .............................. = Enabled

{(E)nabled, (D)isabled}

6) Compression PRetry Time ............................................ = 3

{1..10}

7) Compression PRetry Count .......................................... = 10

{3..255}

8) Fragmentation Interleaving ............................................= Disable
{(E)nabled, (D)isabled}

Enter the value for each parameter after the colon prompt (:). An additional field,

DLCI

Number

, is displayed if you do not specify a DLCI number in the

fradd

command. The remain-

ing parameters are the same ones used for the

frmodify

command. See Modifying a Virtual

Circuit on page 29-29 for information on each of these parameters.

When you have entered values in all fields, the following prompt displays

Do you want to configure additional DLCIs? {(Y)es, (N)o}

Enter a

to set up additional virtual circuits or enter

to exit the

fradd

command. If you

enter

, then you are prompted for all virtual circuit parameters again.
