Monitoring Ethernet Interfaces
Bytes Number of bytes sent
Unicast Number of unicast packets sent
Multicast Number of multicast packets sent
Broadcast Number of broadcast packets sent
Errors Total number of errors in all transmitted packets; note that some
packets might contain more than one error
Discards Total number of discarded outgoing packets
Mac Errors Number of outgoing packets discarded because of MAC
sublayer failures
Deferred Number of packets that the router delayed sending because
the line was busy. In half duplex mode, a high number of deferrals
means the link is very busy with traffic from other stations. In full duplex
mode, when the link is always available for transmission, this number
is zero.
No Carrier Number of packets sent when carrier sense was unavailable
Collisions Analysis of the collisions that occurred
Single Number of packets sent after one collision
Multiple—Number of packets sent after multiple collisions
Late—Number of packets aborted during sending because of collisions
after 64 bytes
Excessive—Number of packets not sent because of too many collisions
Policed Statistics Number of packets that exceeded the number allowed
and were policed (or dropped)
ARP Statistics Analysis of ARP traffic on this interface; In fields are for
traffic received on the interface and Out fields are for traffic sent on the
interface
ARP requests Number of ARP requests
ARP responses Number of ARP responses
Errors Total number of errors in all ARP packets
Discards Total number of discarded ARP packets
Administrative qos-shaping-mode QoS shaping mode:
disabled Shaping mode is configured but not operational
frame Statistics are reported about bytes in frames, such as transmitted
bytes and dropped bytes.
cell Shaping mode for shaping and policing rates is cell-based; resulting
traffic stream conforms exactly to the policing rates configured in
