Software Release 4.1
outerrrors count
This field displays how many outbound packets contained errors that prevented their transmission.
RxBabErr
This field displays how many receiver babble errors occurred.
EthBusErr
This field displays how many Ethernet bus errors occurred on the Ethernet controller.
CRCError
This field displays how many CRC errors occurred on the Ethernet controller.
RxOverrun
This field displays how many receiver overrun errors occurred on the Ethernet controller.
Late Collision
This field displays how many late collisions occurred on the Ethernet controller. A normal collision
occurs during the first 512 bits of the frame transmission. A collision that occurs after the first 512
bits is considered a late collision.
A late collision is a serious network problem because the frame being transmitted is
discarded. A late collision is most commonly caused by a mismatch between
duplex configurations at the ends of a link segment.
RetransLimitExp
This field displays how many times the retransmit limit has expired.
TxUnderrun
This field displays how many transmission-underrun errors occurred on the Ethernet controller.
CarSenseLost
This field displays how many carrier sense lost errors occurred on the Ethernet controller.
8.12 EXPANDED STATS PAGE
The Expanded Stats web page provides statistics that the Canopy module collects. To facilitate
troubleshooting, a Canopy technical support representative may ask the operator for specific
information from this web page.
The Expanded Stats page includes a link to a Reg Failed SMs web page, which provides
• the MAC address of each SM that attempted to register with this AP but failed.
• the time of the attempt.
• the reason for the failure.
A power cycle or reboot drops the contents of this page.
