We sort on the total number of ICMP errors received back by an IP source.
Note: we are showing the errors per sample period (30 seconds).
There are six counters. If a counter == 0, we do not display it.
The counter tags are T:U:P:Un:R:X and they mean:
T: TCP packets sent by an IP source.
U: UDP packets sent by an IP source.
P: ICMP echo request packets sent by an IP source.
Un: ICMP unreachable packets sent back to that IP source.
R: ICMP redirect packets sent back to that IP source.
X: ICMP ttl eXceeded packets sent back to that IP source.
