Obtaining Status and Statistical Information

Page 29-49

DLCI Layer Information

The information in this section of the display provides statistics on virtual circuits. Each row in
this table corresponds to one virtual circuit.

DLCI Num

The

DLCI

number assigned to this virtual circuit. This value is only valid locally; the same

virtual circuit on the other end of the Frame Relay line may or may not use the same

DLCI

for this VC.

Admin/Oper Status

This field shows the Administrative and Operational Status of this

virtual circuit

. The status

indicator before the slash refers to the Administrative Status. If

UP

, then the virtual circuit

has been enabled and can transmit data as long as its Operational Status is also UP. If the
Administrative Status is

DN

, then the VC will not pass data even if its physical connection

is good.

The status indicator after the slash refers to the Operational Status. If

UP

, then the virtual

circuit is capable of passing data. If

DN

, then the

VC

cannot pass data because the

network has declared the virtual circuit inactive, the network does not respond to

STATUS

ENQUIRY

messages, or the

VC

is Administratively Down.

DLCI Type

The type of virtual circuit will be either

Configured

or

Learned

. Configured means this VC

is a management, or control, circuit that is used by Frame Relay protocols, such as the

DLCMI

protocols, to pass various status messages. The Frame Relay network does not self-

configure management virtual circuits. Data VCs can become “configured” if you use

frmodify

to change any of the default settings for the Data VC. Learned means this is a

Data VC that the Frame Relay network informed the

WSX

module about through status

messages (using a Control VC).

Note

The

VC Type

of the management

DLCI

(0 or 1023) is

always

configured

since the Frame Relay network does

not dynamically configure management virtual circuits.

Frames In

The number of frames received on this VC since it was created.

Frames Out

The number of frames transmitted on this VC since it was created.

Octets In

The number of octets, or bytes, received on this VC since it was created.

Octets Out

The number of octets, or bytes, transmitted on this VC since it was created.
