Configuring ATM Routing and PNNI
PNNI Connection Trace
Note
You can modify the maximum number of concurrent PNNI connection traces by using the
atm pnni
trace max-concurrent
global configuration command. The range is 1 to 100.
Note
You can modify the maximum size of the PNNI trace transit list (TTL) information elements (IEs) by
using the
atm pnni trace transit-list max-size
global configuration command. Its default max size
(1466 bytes) can hold trace information for 35 to 45 nodes, depending on the trace options used. If a
single call traverses more than 45 nodes in a PNNI network, use this command to increase the size of the
TTL IE to accommodate all the trace information.To revert to the default value, use the
no
form of the
command.
Examples
The following example displays the
clear atm pnni trace connection all
command to delete all of the
active and accepted PNNI connection traces:
Switch#
clear atm pnni trace connection all
The following example displays the
clear pnni trace connection delete
command with the index
number to delete a specific PNNI connection trace.
Switch#
clear atm pnni trace connection 100
Designating PNNI Trace Boundaries
This section describes how to create PNNI trace boundaries. If a trace enters the switch at a boundary
interface, it is incomplete. If a trace terminates at a boundary interface, it is successful. Any ATM
interface can be configured as a trace boundary, however, it is only meaningful for PNNI interfaces.
To designate an ATM interface as a PNNI connection trace boundary, use the following command in the
privileged EXEC mode:
Note
All non-ATM interfaces are not boundary interfaces by default.
Example
The following example shows how to configure an ATM interface as a PNNI connection trace boundary:
Switch(config)#
interface atm 3/0/0
Switch(config-if)#
atm pnni trace boundary
Command
Purpose
atm pnni trace boundary
Designates an ATM interface as a PNNI
connection trace boundary.
