IP Router Configuration
7705 SAR OS Router Configuration Guide 179
L4 Load Balance Indicates the L4 load balance
uRPF Chk Indicates whether unicast reverse path forwarding (uRPF) checking is
enabled or disabled on this interface
uRPF Fail Bytes The number of uRPF failures, in bytes
uRPF Chk Fail Pkts The number of uRPF checking failures, in packets
Rx Pkts
Rx Bytes
The total number of IPv4 and IPv6 packets or bytes received on the
interface. This output field may display N/A for spoke SDP and routed
VPLS interfaces due to MPLS packets not contributing to this statistics
counter.
Rx V4 Pkts
Rx V4 Bytes
The number of IPv4 packets or bytes received on the interface. This
output field may display N/A for spoke SDP and routed VPLS
interfaces due to MPLS packets not contributing to this statistics
counter.
Rx V4 Discard Pk*
Rx V4 Discard Byt*
The total number of IPv4 receive packets or bytes discarded on the
interface
Inv Hdr CRC Pkts
Inv Hdr CRC Bytes
The number of packets or bytes received on the interface with an invalid
IPv4 header CRC value
Applies to IPv4 only
Inv Length Pkts
Inv Length Bytes
The number of packets or bytes received on the interface with invalid
length information in the header. Invalid length information includes an
IP header length of less than 20 bytes or greater than the total IP packet
length, or an IP packet larger than the Layer 2 frame length.
Inv GRE Protoco*
Inv GRE Protocol*
The number of packets or bytes received on the network interface with
an unsupported GRE header. The only supported protocol type is MPLS
unicast (0x8847). All GRE packets received on an access interface that
are meant to be terminated at the node are also discarded for this reason.
Dest Unreach Pk*
Dest Unreach Byt*
The number of packets or bytes received on the interface with no route
to the destination
Inv Mcast Addr *
Inv Mcast Addr B*
The number of packets or bytes discarded on the interface due to
unsupported multicast addresses
Directed Bcast *
Directed Bcast B*
The number of directed broadcast packets or bytes discarded on the
interface when the interface is not enabled for directed broadcast
packets
Applies to IPv4 only
