Service Manual

Keyword Denition
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 prexes; 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 buer is full and the incoming packet are dropped.
