Packets = 64 bytes The number of packets this size received/transmitted
successfully on this port.
Packets 65-127 bytes The number of packets this size received/transmitted
successfully on this port.
Packets 128-255

successfully on this port.
Packets 1024-1518
bytes
The number of packets this size received/transmitted
successfully on this port.
FCS Errors The number of valid-size packets received on this
port with proper framing but discarded because of

•
1522 bytes if a VLAN tag exists
