Usage 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 the system.
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. The system sends an arp request prior to forwarding an IP packet. If a reply is not received, the system 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.

The F10 Monitoring MIB provides access to the following statistics.
