Ta b l e 40 show ip traffic Field Descriptions
Field Description
format errors Indicates a gross error in the packet format, such as an impossible Internet
header length.
bad hop count Occurs when a packet is discarded because its time-to-live (TTL) field was
decremented to zero.
encapsulation failed Usually indicates that the router had no Address Resolution Protocol (ARP)
request entry and therefore did not send a datagram.
no route Counted when the Cisco IOS software discards a datagram it did not know
how to route.
