Information
The following describes the show ip traffic summary shown in the following example.
Keyword Definition
unknown protocol... No receiver for these packets. Counts packets whose protocol type
field is not recognized by FTOS.
not a gateway... Packets can not be routed; the host/network is unreachable.
security failures... Counts the number of received unicast/multicast packets that could
not be forwarded due to:
• route not found for unicast/multicast; ingress interfaces do
not belong to the destination multicast group
• destination IP address belongs to reserved prefixes; the
host/network is unreachable
bad options... Unrecognized IP option on a received packet.
Frags: IP fragments received.
... reassembled Number of IP fragments that were reassembled.
... timeouts Number of times a timer expired on a reassembled queue.
... too big Number of invalid IP fragments received.
... couldn’t fragment Number of packets that could not be fragmented and forwarded.
...encapsulation
failed
Counts packets which could not be forwarded due to ARP resolution
failure. FTOS sends an arp request prior to forwarding an IP packet.
If a reply is not received, FTOS repeats the request three times.
These packets are counted in encapsulation failed.
Rcvd:
...short packets The number of bytes in the packet are too small.
...bad length The length of the packet was not correct.
...no port broadcasts The incoming broadcast/multicast packet did not have any listener.
...socket full The applications buffer is full and the incoming packet are dropped.
