Frames Tx with more than one Collision. A count of the frames that were involved in more than one collision and were
subsequently transmitted successfully. This counter is incremented when the transmit status is reported as Transmit OK,
and the value of the attempts variable is greater than 2 and less than or equal to the attempt limit.
Frames Tx after Deferral. A count of the frames that were delayed being transmitted on the first attempt because the
medium was busy. The frames involved in any collision are not counted.
Custom Statistics
NOTE: Custom statistics are available only for an enabled Broadcom network adapter.
Out of Recv. Buffer. The number of times the adapter ran out of Receive Buffer Descriptors. This information is only
available for Broadcom NetXtreme II adapters.
Frames size less than 64-byte with bad FCS. The number of frames with a size less than 64 bytes with bad FCS.
MAC Rx w/ Pause Command and Length = 0. MAC control frames with the pause command and a length equal to 0.
MAC Rx w/ Pause Command and Length greater than 0. MAC control frames with the pause command and a length
greater than 0.
MAC Rx w/ no Pause Command. MAC control frames with no pause command.
MAC Sent X-on. MAC Transmit with X-on was on.
MAC Sent X-off. MAC Transmit with X-on was off.
Large Send Offload Transmit Requests. The number of times the adapter was requested to transmit a packet performing
TCP segmentation.
Total Offload TCP Connections. The total number of offloaded TCP connections.
VIEWING RESOURCE RESERVATIONS
NOTES:
• Resource Reservation information is only available for Broadcom NetXtreme II adapters and VBD drivers.
• Not all offload technologies are available with all adapters.
The Resource Reservations section shows the number of connections allocated to an offload technology: TOE and iSCSI.
• TCP Offload Engine (TOE) for accelerating TCP over 1 GbE, 2.5 GbE, and 10 GbE.
• Internet Small Computer Systems Interface (iSCSI) offload for accelerating network storage access featuring
centralized boot functionality (iSCSI boot).
You can also view the number of unlicensed resources and unallocated resources.
TOE and iSCSI can only be configured on certain adapters and require a license key. License keys are preprogrammed in
the hardware.
