Alert String Alert Description
First Time Install Important installation information for your switch.
Too many undersized/
giant packets
A device connected to this port is transmitting packets shorter than 64 bytes or longer than
1518 bytes (longer than 1522 bytes if tagged), with valid CRCs (unlike runts , which have invalid
CRCs).
Excessive jabbering A device connected to this port is incessantly transmitti ng packets (“jabbering”), detected as
oversized packets with CRC errors.
Excessive CRC/alignment
errors
A high percentage of data errors has been detected on this port. Possible causes include:
•Faulty cabling or invalid topology.
•Duplex mismatch (full-duplex configured on one end of the link, half-duplex confi gured on
the other)
•A malfunctioning NIC, NIC driver, or transceiver
Excessive late collisions Late collisions (co llisions detected after transmitting 64 bytes) hav e been detected on this
port. Possible causes include:
•An overextended LAN topology
•Duplex mismatch (full-duplex configured on one end of the link, half-duplex confi gured on
the other)
•A misconfigured or faulty device co nnected to the port
High collision or drop rate A large number of collisions or packet drops have occurred on the port. Possible causes
include:
•A extremely high level of traffic on the port
•Duplex mismatch
•A misconfigured or malfunctioning NIC o r transceiver on a device connected to this port
•A topology loop in the network
Excessive broadcasts An extremely high percentage of broadcasts was receive d on this port. This degrades the
performance of all devices connected to the port. Possible causes incl ude:
•A network topology loop—this is the usual cause
•A malfunctioning device, NIC, NIC driver, or software package
Loss of Link Lost connection to one or multiple devices on the por t.
Loss of stack member The Commander has lost the connection to a stack member.
