l2tp ignore-receive-data-sequencing
•
Use to prevent sequence number verification for data packets received on all L2TP
tunnels in the router. This command does not affect the insertion of sequence numbers
in packets sent from the router.
•
If you are using IP reassembly, we recommend that you set up the router to ignore
sequence numbers in received data packets. Because IP reassembly can reorder L2TP
packets, out-of-order packets can be dropped if sequence numbers are being used on
L2TP data packets.
•
Example
host1(config)# l2tp ignore-receive-data-sequencing
•
Use the no version to cause the router to verify sequence numbers on received L2TP
data packets.
•
See l2tp ignore-receive-data-sequencing.
Monitoring IP Reassembly
This section describes how to set a statistics baseline for tunnel reassembly statistics
and how to display reassembly statistics.
Setting Statistics Baselines
You can use the baseline ip tunnel-reassembly command to set a statistics baseline
for tunnel reassembly statistics on the current virtual router. The router implements the
baseline by reading and storing the statistics at the time the baseline is set and then
subtracting this baseline whenever you retrieve baseline-relative statistics.
baseline ip tunnel-reassembly
•
Use to set a statistics baseline for tunnel reassembly statistics on the current virtual
router.
•
To display reassembly statistics relative to the baseline, use the show ip tunnel
reassembly statistics command with the delta keyword. For information about
displaying baselined statistics, see “show ip tunnel reassembly statistics” on page 273.
•
Example
host1:vr2# baseline ip tunnel-reassembly
•
There is no no version.
•
See baseline ip tunnel-reassembly.
Displaying Statistics
The router keeps several statistics that are useful for diagnostic purposes. These statistics
are organized by virtual router, and some are broken out by protocol as well. You can
display statistics for a single virtual router or for all virtual routers. You can also display
statistics relative to a baseline.
