Use the buttons to perform the following tasks:
• Click Clear Counters to clear all the counters. This resets all statistics for this port to the default values.
• Click Clear All Counters to clear all the counters for all ports on the switch. The button resets all statistics
for all ports to default values.
• Click Refresh to refresh the page with the most current data from the switch.
To retain the changes across the switch's next power cycle, click System > Configuration Storage > Save.

Port Detailed Statistics Fields (Continued)
Description
The number of Generic Attribute Registration Protocol (GARP) VLAN Registration Protocol (GVRP)
PDUs transmitted or received by the interface.
The number of GARP Multicast Registration Protocol (GMRP) PDUs transmitted or received by the
interface.
The number of Extensible Authentication Protocol (EAP) over LAN (EAPOL) frames transmitted or
received by the interface for IEEE 802.1X port-based network access control.
The sum of single collision frames discarded, multiple collision frames discarded, and excessive frames
discarded.
A count of the number of successfully transmitted frames on a particular interface for which
transmission is inhibited by exactly one collision.
A count of the number of successfully transmitted frames on a particular interface for which
transmission is inhibited by more than one collision.
A count of frames for which transmission on a particular interface fails due to excessive collisions.
The total number of frames discarded because the transmit FIFO buffer became empty during frame
transmission.
The number of times attempted GMRP registrations could not be completed.
The number of times attempted GVRP registrations could not be completed.
The number of inbound packets which were chosen to be discarded to prevent them from being
delivered to a higher-layer protocol, even though no errors had been detected. One possible reason
for discarding such a packet is to free up buffer space.
The total number of inbound packets that contained errors preventing them from being delivered to a
higher-layer protocol.
The total number of frames discarded as this port was overloaded with incoming packets, and could
not keep up with the inflow.
The total number of packets received that had a length (excluding framing bits, but including FCS
octets) of between 64 and 1518 octets, inclusive, but had a bad Frame Check Sequence (FCS) with a
non-integral number of octets.
The total number of packets received that were longer than 1518 octets (excluding framing bits, but
including FCS octets), and had either a bad Frame Check Sequence (FCS) with an integral number of
octets (FCS Error) or a bad FCS with a non-integral number of octets (Alignment Error). Note that this
definition of jabber is different than the definition in IEEE-802.3 section 8.2.1.5 (10BASE5) and section
10.3.1.4 (10BASE2). These documents define jabber as the condition where any packet exceeds 20 ms.
The allowed range to detect jabber is between 20 ms and 150 ms.
The total number of packets received that were less than 64 octets in length with ERROR CRC
(excluding framing bits but including FCS octets).
The total number of packets received that were less than 64 octets in length with GOOD CRC
(excluding framing bits but including FCS octets).
The number of frames discarded from this interface due to being a frame type that the interface
cannot accept.
The amount of time in days, hours, minutes, and seconds, that has passed since the statistics for this
interface were last reset.
