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.

Monitoring IP Reassembly
Use the no version to return IP tunnel reassembly to the default, disabled.
See ip tunnel reassembly.
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.
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 283.
Example
host1:vr2#baseline ip tunnel-reassembly
There is no no version.
See baseline ip tunnel-reassembly.
