Function
The display l2tp-user urpf discard statistics command displays the number of URPF-dropped L2TP user packets.
This command is supported only on the NetEngine 8000 F1A.
Usage Guidelines
After IPv4 or IPv6 URPF strict check is enabled in the virtual template view, a user can run the display l2tp-user urpf discard statistics command to view the number of IPv4 or IPv6 URPF-dropped L2TP user packets so that a user can check whether packets of incorrect source IPv4 addresses or source IPv6 addresses are sent.

The actual command output varies according to the device. The command output here is only an example.

| Slot | slot ID of an interface board to which a user belongs. |
| IPv4 discard packets (high, low) | Statistics on discarded IPv4 packets. "-" indicates no statistics; otherwise, the statistics will be shown in the form of "(high, low)". The statistics is calculated using 64-bit counter size, the left-most 32 bits are high value, and the right-most 32 bits are low value. Both the high and low values are in decimal. The statistics=high* (0xFFFFFFFF) +low. |
| IPv6 discard packets (high, low) | Statistics on discarded IPv6 packets. "-" indicates no statistics; otherwise, the statistics will be shown in the form of "(high, low)". The statistics is calculated using 64-bit counter size, the left-most 32 bits are high value, and the right-most 32 bits are low value. Both the high and low values are in decimal.
