Usage Guidelines

Usage Scenario

After IPv4 or IPv6 URPF strict check is enabled in the virtual template view, a user can run the display ppp-user urpf discard statistics command to view the number of IPv4 or IPv6 URPF-dropped PPPoE user packets so that a user can check whether packets of incorrect source IPv4 addresses or source IPv6 addresses are sent.

Precautions

In VS mode, this command is supported only by the admin VS.

Example

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

Item	Description
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. The statistics=high* (0xFFFFFFFF) +low.
