TABLE 117
RPF statistics by port
Field
Description
RPF mode:
This display parameter can have one of the following two values:
•
loose – RPF will permit a packet as long as the source address matches a
known route entry in the routing table. It will drop a packet if it does not
match a route entry.
•
strict – RPF requires that a packet matches a known route entry as
described for loose mode and also that it arrives at the configured
interface as described in the router table’s next hop information. It will
drop a packet that does not match both of these criteria.
RPF Log:
This display parameter displays the RPF Log Configuration Status:
•
Enabled – The RPF log feature has been configured.
•
Disabled – The RPF log feature has not been configured
number unicast RPF drop
The number of packets that have been dropped due to failure of the RPF test.
number unicast RPF suppressed
drop
The number of packets that would have been dropped due to failure of the RPF
test but were not dropped because they matched conditions set in an ACL with
the flag set in the suppress-rpf-drop command.
