Format of “All Ports Dropped Packet” MIB Counters
Note: “All Ports Dropped Packet” MIB Counters do not indicate overflow or validity; therefore, the application must keep track of
overflow and valid conditions.
“All Ports Dropped Packet” MIB counters are read using indirect memory access. The address offsets for these counters
are shown in Table 17.

Description
Total Rx packets (bad packets included) that are between 1024 and 1522 octets in
length (upper limit depends on max packet size setting)
Tx lo-priority good octet count, including PAUSE packets
Tx hi-priority good octet count, including PAUSE packets
The number of times a collision is detected later than 512 bit-times into the Tx of a
packet
Number of PAUSE frames transmitted by a port
Tx good broadcast packets (not including error broadcast or valid multicast packets)
Tx good multicast packets (not including error multicast packets or valid broadcast
packets)
Tx good unicast packets
Tx packets by a port for which the 1st Tx attempt is delayed due to the busy medium
Tx total collision, half duplex only
A count of frames for which Tx fails due to excessive collisions
Successfully Tx frames on a port for which Tx is inhibited by exactly one collision
Successfully Tx frames on a port for which Tx is inhibited by more than one collision
