This command configures the parameters that define the routing path
for a DLCI. It must match with the DLCI configuration parameters. The values
entered with these commands should be noted as they will be needed to configure
the
frame-relay and
dlci commands also in this configuration
mode.

Deletes the routing path entry from the configuration.
path
path_id
Identifies a specific path configuration that will be associated with
a DLCI. The
path_id must be an integer from 1 to 3.
ds1
connects |
e1
connects
Selects the channelization for the connection.
DS1: (AKA: T1) Is associated with North American networks and
would be the best choice to work with the SONET (can also work with SDH)
framing selected with the
card configuration command. DS1 splits the
path into 28 logical connections.
connects: Defines the number of logical
connections supported via the DS1. The selection must be an integer from 1 to
28.
E1: is associated with European networks and would be
associated with the SDH (can also work with SONET) framing selected with the
card configuration command. E1 splits the
path into 21 logical connections.
connects: Defines the number of logical
connections supported via the E1. The selection must be an integer from 1 to
21.
service-type { frame-relay | mtp2 }
Specifies the service type to be used for this path. When
multi-service is enabled at the card level,
different services are supported at the path-level for this port. For
additional information, refer to the description of the
service-type command in the
Card Configuration Mode Commands chapter.
frame-mapping
Frame mapping sets the channelization according to the national
standards that correlate with the framing/speed standards. This option selects
the mapping of containers (C), virtual containers (VC), tributary units (TU),
and tributary unit groups (TUG), that is appropriate for the channel
characteristics:
-
tu11-au3: Appropriate for DS1 in SDH.
Maps as follows AU-3—VC-3— m# —TUG-2— m# —TU-12—VC-12—C-12
-
tu11-au4: Appropriate for DS1 in SDH.
Maps as follows AU-4—VC-4—TUG-3— m# —TUG-2— m# —TU-11—VC-11—C-11
-
tu12-au3: Appropriate for E1 in SDH.
Maps as follows AU-3—VC-3— m# —TUG-2— m# —TU-12—VC-12—C-12
-
tu12-au4: Appropriate for E1 in SDH.
Maps as follows AU-4—VC-4—TUG-3— m# —TUG-2— m# —TU-12—VC-12—C-12
multiplexing index# index#
index#: TUG-2 index - Must be an integer
from 1 to 7 to identify a multiplex channel between TUG-2 and VC-3 (E1) or
TUG-3 (DS1).
index#: TU index - Must be an integer from 1
to 4 (DS1) or 1 to 3 (E1) to identify a multiplex channel between TU-11 (DS1)
and TUG-2 or between TU-12 (E1) and TUG-2.
framing
mode
Defines the framing modes to be used for the channelization to E1 or
T1 of the (optical) port.
timeslots
timeslots
Defines up to 8 timeslot groupings for multiple fractional DS1/E1
channels. Each slot is 2.048/32 Mbytes. Slots 0 and 16 are reserved for
synchronization and alarms. Slots 1-15 and 17-31 are used for data. Timeslots
must be unique -- a timeslot can not be used in more than one grouping.
timeslots: Must be an integer from 1 to 31.
Timeslot groups are separated by spaces and can consist of a single slot and/or
a range indicated with a hyphen. Example: 3,7-10 is a single fractional group.
NOTE there is no space after the comma. Timeslots must be unique -- a timeslot
can not be used in more than one grouping.
frame-relay
Enables definition of a Frame Relay connection with the
frame-relay command.
Important:
For release 8.1 and higher, this feature has been moved to the
frame-relay command.
intf-type
intf_type
Selecting the interface type specifies signaling parameters for the
DLCI, options include:
-
dce: Selects data circuit-terminating
equipment -type signaling.
-
dte: Selects data terminal equipment
-type signaling.
-
nni: Selects the network-to-network
interface
Default: DTE for Release 8.0
Default: DCE for Release 8.1
Important:
For release 8.1 and higher, this feature has been moved to the
frame-relay command.
lmi_type
lmi_type
Default:
none.
Line management type options include:
Any of the above LMI types can take one or more additional options
-
n391
value - Number of keep
exchanges before requesting a full status message. Default is 6.
value must be an integer from 1 to 255.
-
n392
value - Error Threshold
value. Default is 2.
value must be an integer from 1 to 10.
-
n393
value - Monitored events count value.
Default is 2.
value must be an integer from 1 to 10.
-
t391
value - Timer to send
messages. Default is 10.
value must be an integer from 5 to 30.
-
t392
value - Polling
verification timer value. Default is 15.
value must be an integer from 5 to 30.
Important:
For release 8.1 and higher, this feature has been moved to the
frame-relay command.
Usage Guidelines
Defines the signaling characteristics of a frame relay connection or
timeslots for a fractional connection.
Use this command to create E1 ports or fractional E1 ports. Fractional
E1 ports are created with the timeslot definitions. The fractional E1 port can
consist of one or more or all of the timeslots.
Examples
In the first example, define timers for the q933a LMI-type.
path 1 e1 1 tu12-au4 1 1 framing crc4 mapping-mode bit-async frame-relay intf-type dce lmi_type q933a n391 6 n392 2 n393 2 t391 10 t392 15
The next example defines 3 groups of fractional timeslots with group 1
having slots 1-5 and 8, group 2 having slot 22-25, and group 3 having slots 31.
path 1 e1 1 tu12-au3 1 1 framing cas mapping-mode bit-async timeslots 1-5,8 22-25 31
