Local Area Network
179
TX Late Collisions
This counter indicates the
number of transmit late collisions
Excessive round trip distance for
packets in half-duplex networks.
Network violates IEEE-802.3
standard for physical network
length or there are too many
(more than 3) repeaters/hubs in
the network.
Ensure that network design is
IEEE-802.3 compliant.
Defective network device is not
correctly sensing that the
network is busy.
Locate and replace defective network
device.
TX Discards
The total number of transmit
packets discarded.
Due to lack of transmit
resources— e.g., transmit FIFO
overflow, or an internal MAC
transmit error.
Contact Mitel Technical Support.
Excessive Collisions
This counter indicates the total
number of packets that failed to
be sent after 16 collisions.
.
Loops in the network, e.g. more
than one active network
connections to the same network
device.
Remove redundant network connections
or enable STP/RSTP where appropriate.
Defective network device is not
correctly sensing if the network
is busy.
Replace defective network device.
Duplex mismatch. Verify that duplex setting are consistent
at both ends of LAN segment.
Busy network. Reconfigure network into more segments
by using bridges, routers or ethernet
switches.
