and was otherwise well formed. This count does not include
range or length errors.
Undersize frames may be caused by a faulty or corrupt LAN driver.
Oversize Frames
- This counter increments each time a frame is
received that exceeds 1518 bytes (non-VLAN) or 1522 bytes (on a
VLAN), contains a valid FCS, and was otherwise well formed.
In general you should not see oversize frames, though their
presence is not a guarantee that the network is failing. Oversize
frames may be caused by a faulty or corrupt LAN driver.
Fragments
- This counter increments for each frame received that
contains an invalid FCS and is less than 64 bytes in length. This
includes integral and non-integral lengths.
Jabbers
- This counter increments for each frame that exceeds
1518 bytes in length (non-VLAN) or 1522 bytes (on a VLAN) and
contains an invalid FCS. This includes alignment errors.
Possible causes include a bad NIC or transceiver, faulty or corrupt
NIC driver, bad cabling, grounding problems, and nodes jamming
the network due to above normal collision rates.
A possible solution would be to identify the node(s) that are
sending out excessive errors and replace the defective hardware.
Dropped Frames
- This counter increments for each frame that is
received but is later dropped due to a lack of system resources.
Control Frames
- This counter increments for each MAC control
frame received (PAUSE and unsupported) from 64 bytes to 1518
bytes (non-VLAN) or 1522 bytes (on a VLAN) in length, with a
valid CRC.
PAUSE Frames
- This counter increments each time a PAUSE MAC
control frame is received that is from 64 bytes to 1518 bytes (non-
VLAN) or 1522 bytes (on a VLAN) in length, with a valid CRC.
Unknown OP codes
- This counter increments each time a MAC
control frame is received that is from 64 bytes to 1518 bytes (non-
VLAN) or 1522 bytes (on a VLAN) in length, and contains an
opcode other than PAUSE, but the frame has a valid CRC.
