Port Statistics/Statistics Menu
The Port Statistics/Statistics Menu, shown in Figure 6-68, allows you to view
the port or RMON statistics.
• Port Statistics - Displays statistics on network traffic passing through the
selected port. You have a choice of viewing port or RMON statistics.
• RMON Statistics - Displays statistics for each port from RMON group 1
(RMON groups 2, 3, and 9 can only be accessed using SNMP management
software).
Select OK to return to the previous panel.
Port Statistics
Port Statistics, on the screen shown in Figure 6-69, display key statistics
from the Interfaces Group and Ethernet-like MIBs for each port. Error sta-
tistics on the traffic passing through each port are displayed. This informa-
tion can be used to identify potential problems with the Switch (such as a
faulty port or unusually heavy loading). The values displayed have been
accumulated since the last system reboot.
Select the required port.

Interfaces
• In Octets - The total number of octets received on the interface, includ-
ing framing characters.
• In Unicast Pkts - The number of unicast packets delivered to a higher-
layer protocol.
• In Non-Unicast Pkts - The number of non-unicast (that is, subnetwork-
broadcast or subnetwork-multicast) packets delivered to a higher-layer
protocol.
• In Discards - 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.
• In Errors - The number of inbound packets that contained errors pre-
venting them from being deliverable to a higher-layer protocol.
• Alignment Errors - The number of alignment errors (mis-synchronized
data packets).
• Out Octets - The total number of octets transmitted out of the interface,
including framing characters.
• Out Unicast Pkts - The total number of packets that higher-level proto-
cols requested be transmitted to a subnetwork-unicast address, including
those that were discarded or not sent.
