OmniSwitch 6250 CLI Reference Guide
Number of "time exceeded" messages that were sent/received by the
switch. These occur when a packet is dropped because the TTL counter
reaches zero. When a large number of these occur, it is a symptom that
packets are looping, that congestion is severe, or that the TTL counter
value is set too low. These messages also occur when all the fragments
trying to be reassembled do not arrive before the reassembly timer
expires.
Number of messages sent/received which indicate that an illegal value
has been detected in a header field. These messages can indicate a prob-
lem in the sending host's IP software or possibly the gateway's soft-
ware.
Number of messages sent/received that tell a host that it is sending too
many packets. A host should attempt to reduce its transmissions upon
receiving these messages.
Number of ICMP redirect messages sent/received by the switch.
Number of ICMP echo messages sent/received by the switch to see if a
destination is active and unreachable.
Number of echo reply messages received by the switch.
Number of time stamp request messages sent/received by the switch.
Number of time stamp reply messages sent/received by the switch.
Number of address mask request messages that were sent/received by
the switch in an attempt to determine the subnet mask for the network.
