6 Utility Commands
Collisions Frames The best estimate of the total number of collisions on this Ethernet seg-
ment.
Time Since Counters Last Cleared The elapsed time, in days, hours, minutes, and seconds
since the statistics for this port were last cleared.
The display parameters, when the argument is “switchport” is as follows:
Broadcast Packets Received The total number of packets received that were directed to the
broadcast address. Note that this does not include multicast packets.
Packets Received With Error The number of inbound packets that contained errors prevent-
ing them from being deliverable to a higher-layer protocol.
Packets Transmitted Without Error The total number of packets transmitted out of the
interface.
Broadcast Packets Transmitted The total number of packets that higher-level protocols
requested to be transmitted to the Broadcast address, including those that were
discarded or not sent.
Transmit Packet Errors The number of outbound packets that could not be transmitted
because of errors.
Address Entries Currently In Use The total number of Forwarding Database Address Table
entries now active on the switch, including learned and static entries.
VLAN Entries Currently In Use The number of VLAN entries presently occupying the
VLAN table.
Time Since Counters Last Cleared The elapsed time, in days, hours, minutes, and seconds
since the statistics for this switch were last cleared.
show interface ethernet
This command displays detailed statistics for a specific interface or for all CPU traffic based
upon the argument.
Format
show interface ethernet {<slot/port> | switchport}
Mode Privileged EXEC
When you specify a value for
<slot/port>, the command displays the following information:
Media Type The type of physical medium for the Ethernet. The possible values are
10Base-T, 100Base-TX, 100Base-FX, 1000Base-X, 1000Base-T and
10GBase-X.
ARP Type Encapsulation type for the network address. The value is always ARPA.
Packets Received
Total Packets Received (Octets) - The total number of octets of data (includ-
ing those in bad packets) received on the network (excluding framing bits but
including Frame Check Sequence (FCS) octets). This object can be used as a
reasonable estimate of Ethernet utilization. If greater precision is desired, the
etherStatsPkts and etherStatsOctets objects should be sampled before and
after a common interval. The result of this equation is the value Utilization
