Relationships between some counters
Some of the values for counters displayed using the show np statistics command are the result of
adding the contents of more than one counter.
and
describe these relationships
between NP counters displayed.
TABLE 9
Tx counters
TX counter (per port)
Explanation
Tx Sent to MAC Packet
Total number of packets sent to MAC for transmit
Tx Raw Good Packet
Total number of packets sent to egress processing logic that pass the initial length
checks (min, max, offsets, bad packet etc.)
Tx Source Port
Suppression Drop
Number of packets dropped because of transmit source port suppression
Tx Bad Packet Count
Total number of packets dropped in egress logic that fail the initial length checks (min,
max, bad packet etc.)
Tx Unicast Packet
Number of unicast packets transmitted (from MAC DA)
Tx Broadcast Packet
Number of broadcast packets transmitted (from MAC DA)
Tx Multicast Packet
Number of multicast packets transmitted (from MAC DA)
Tx Receive From TM
Number of packets received from TM
Tx ACL Drop
Number of packets that have been dropped by the Outbound ACL Logic
Tx IPv4 Packet
Number of IPv4 packets transmitted out the port (Etype==0x0800 & IPver == 0x4)
Tx IPv6 Packet
Number of IPv6 packets transmitted out the port (Etype==0x86DD & IPver == 0x6)
Tx IPv4 Byte
Counts packet Bytes (+FCS) that have IPv4 etype (0x0800) and IP version equals 0x4
Tx IPv6 Byte
Counts packet Bytes (+FCS) that have IPv6 etype (0x86DD) and IP version equals 0x6
