Keyword Definition
unknown protocol... No receiver for these packets. Counts those packets whose protocol type field is not
recognized by FTOS.
not a gateway... Packets can not be routed; 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; host/network 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 those 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 was full and the incoming packet had to be dropped.
