Keyword Definition
unknown
protocol... No receiver for these packets. Counts packets whose
protocol type field is not recognized by Dell Networking OS.
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. Dell Networking OS sends an arp request
prior to forwarding an IP packet. If a reply is not received,
Dell Networking OS 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.
