GBEI Statistics Summary
FPGA Media Unrecovered – When FEC is enabled, indicates number of bad or
lost Ethernet packets that could not be recovered, for which a packet with a
payload of null MPEG packets has been substituted
FPGA UDP Checksum Error – Indicated number of Ethernet packets received
with incorrect UDP checksums
FPGA Non-Compliant Pkt – Indicates number of Ethernet packets received
which are not valid transport stream packets
FPGA Packets Dropped – Indicates number of IP packets that have been
dropped due to a buffer overrun condition
FPGA Null Underrun – Indicated number of Null MPEG packets generated to the
WAN due to buffer underrun conditions
FPGA Null Out-of-Sync – Indicates the number of null MPEG packets that have
been generated to the WAN due to a loss of (MPEG packet) synchronization
condition
FPGA Overrun Events – Indicates the number of times that a buffer overrun
condition has occurred
FPGA Underrun Events – Indicates the number of times that a buffer underrun
condition has occurred
FPGA Out-of-Sync Events – Indicates the number of times that a loss of MPEG
synchronization condition has occurred
WAN Good Octets (IN) - The sum of lengths of all good Ethernet frames received
from the IP encapsulation logic (which contains MPEG packets received from the
WAN)
WAN Unicast (IN) ) – The sum of good frames received from the WAN IP
encapsulation logic that have a unicast destination MAC address
WAN Broadcast (IN) – The sum of good frames received from the WAN IP
encapsulation logic that have a broadcast destination MAC address
WAN Multicast (IN) – The sum of good frames received from the WAN IP
encapsulation logic that have a multicast destination MAC address
Mng Good Octets (In) – The sum of lengths of all good Ethernet frames received
from the local GBEI management processor
Mng Bad Octets (In) ) – The sum of lengths of all bad Ethernet frames received
from local GBEI management processor
Mng Unicast (In) ) – The sum of good frames received from the local GBEI
management processor that have a unicast destination MAC address
Mng Broadcast (In) ) – The sum of good frames received from the local GBEI
management processor that have a broadcast destination MAC address
Mng Multicast (In) ) – The sum of good frames received from the local GBEI
management processor that have a multicast destination MAC address
Mng Pause (In) ) – The number of good flow control frames received from local
GBEI management processor
Mng Undersize (In) – Total frames received from the local GBEI management
processor with a length of less than 64 octets but with a valid FCS
Mng Fragments (In) – Total frames received from the local GBEI management
processor with a length of less than 64 octets and an invalid FCS
Mng Oversize (In) – Total frames received form the local GBEI management
processor with a length greater than the maximum size of octets but with a valid
FCS
