Displaying Connection Status
Use the Interface > Port > General (Show Information) page to display the current connection status, including link state,
speed/duplex mode, flow control, and auto- negotiation.

Showing Port or Trunk Statistics
Use the Interface > Port/Trunk > Statistics or Chart page to display standard statistics on network traffic from the Interfaces
Group and Ethernet-like MIBs, as well as a detailed breakdown of traffic based on the RMON MIB. Interfaces and Ethernet-like
statistics display errors on the traffic passing through each port. This information can be used to identify potential problems with
the switch (such as a faulty port or unusually heavy loading). RMON statistics provide access to a broad range of statistics,
including a total count of different frame types and sizes passing through each port. All values displayed have been accumulated
since the last system reboot, and are shown as counts per second. Statistics are refreshed every 60 seconds by default.
NOTE:
RMON groups 2, 3 and 9 can only be accessed using SNMP management software.
The following table lists the options on this page:
Interface - General (Show Information) Options
Port
Port identifier. (Range: 1-10/26/28/52)

down an interface include being administratively disabled, or exceeding traffic boundary limits set
by auto traffic control.
Autonegotiation (Port Capabilities)
Shows if auto-negotiation is enabled or disabled
Oper Speed/Duplex
Shows the current speed and duplex mode
Oper Flow Control
Shows the flow control type used

Interface Statistics
Received Octets
The total number of octets received on the interface, including framing characters.
Transmitted Octets
The total number of octets transmitted out of the interface, including framing characters.
Received Errors
The number of inbound packets that contained errors preventing them from being deliverable to a
higher-layer protocol.
Transmitted Errors
The number of outbound packets that could not be transmitted because of errors.
Received Unicast Packets
The number of subnetwork-unicast packets delivered to a higher-layer protocol.
Transmitted Unicast Packets
The total number of packets that higher-level protocols requested be transmitted to a
subnetwork-unicast address, including those that were discarded or not sent.
Received Discarded Packets
The number of inbound packets which were chosen to be discarded even though no errors had
been detected to prevent their being deliverable to a higher-layer protocol. One possible reason for
discarding such a packet could be to free up buffer space.
