8.13.2 Debugging frame relay and MFR
Debugging affects the performance of the system. After debugging, run the undo debugging
all command to disable it immediately.
When a fault of FR or MFR occurs, execute the following debugging commands in user view
to debug FR or MFR and to locate the fault. For detailed steps, refer to the chapter
"Maintenance and Debugging" in the Nortel Secure Router 8000 Series Configuration Guide -
System Management.
NOTE
z
If you enable the debugging, running the same debugging command on the interface does not take
effect.
z
If you disable the debugging, running the same undo debugging command on the interface does not
take effect.
z
If you select the verbose option, to disable it, use the undo debugging command. For example, after
running the debugging fr packet ip verbose command, the debugging fr packet ip command does
not take effect, and the previous output of the debugging fr packet ip verbose command remains.
Action Command
Enable the FR debugging. debugging fr { all | compress | congestion | de |
lmi | mfr control | mfr fragment |
transmit-rate } [ interface interface-type
interface-number ]
debugging fr { event | ipc }
Enable the packet fragment debugging debugging fr fragment interface interface-type
interface-number dlci-number
Enable the FR inverse ASP. (The
64-byte packets can be output if the
verbose is chosen.)
debugging fr inarp [ verbose ] [interface
interface-type inertface-number [ dlci
dlci-number] ]
Enable the FR packets debugging and
output the debugging information
according to different packets.
debugging fr packet [ ip | ipx | mpls | isis |
