Bytes—Number of bytes received in error-free packets
Unicast—Number of unicast packets received
Multicast—Number of multicast packets received
Broadcast—Number of broadcast packets received
Errors—Total number of errors in all received packets; some packets might contain
more than one error
Discards—Total number of discarded incoming packets
Mac Errors—Number of incoming packets discarded because of MAC sublayer
failures
Alignment—Number of incomplete octets received
CRC—Number of packets discarded because the checksum the router computed
from the data does not match the checksum generated by the originating devices
Too Longs—Number of packets discarded because the size exceeded the MTU
Symbol Errors—Number of symbols received that the router did not correctly
decode
Out—Analysis of outbound traffic on this interface
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; 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
