Configuring ATM Over MPLS Trunks
Configuring ATMoMPLS Trunk Logical Ports
For ATMoMPLS Trunk logical ports, you can configure the fields in the
Administrative tab as described in Table 8-11.
Table 8-11. Add Logical Port: Administrative Tab Fields
Field Action/Description
Bandwidth (Kbps) Allocated – Enter the amount of bandwidth for this logical port.
The default is the amount of bandwidth remaining from the
physical clock rate less any logical ports already configured.
If you are defining more than one ATMoMPLS Trunk logical
port, adjust the bandwidth value to accommodate these virtual
ports.
Available – The total amount of bandwidth available for this
logical port.
For specific guidelines on configuring bandwidth with the
various physical port types, refer to Chapter 2, “About ATM
Logical Ports.”
Enable Path Trace Select the check box to enable path trace for circuits that pass
through this logical port.
Clear the check box (default) to disable path trace.
CrankBack Info
Required
Select the check box to enable collection of crankback
information for circuits that pass through this logical port.
Crankback information is information about dynamic rerouting
of call setups around failed nodes or links (or links with
insufficient resources) on the traced path.
Clear the check box (default) to disable crankback information
collection.
Pass Along Request Select the check box to enable (default) pass along request for
circuits that pass through this logical port. When the path trace
continues through nodes that do not support the path trace
feature, the trace results may contain some gaps between
successive entries of logical nodes and logical ports traversed
by this connection or party.
Clear the check box to disable pass along request. The path
trace will terminate at any switch that does not support the path
trace feature. A partial path trace will be returned.
Path Trace Timeout
(1-65535)
Enter the number of seconds for which you want the trace
results to be maintained in the switch. Enter a value between 1
and 65535, or accept the default value (600).
Maximum Records
(1-200)
Enter the number of trace records that can be present for this
LPort. Enter a value between 1 and 200, or accept the default
value (20).
