Concept Guide

Keyword Denition
... 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 buer is full and the incoming packet are dropped.
The F10 Monitoring MIB provides access to the following statistics.
• IP Statistics: Bcast: Received: Object = f10BcastPktRecv, OIDs = 1.3.6.1.4.1.6027.3.3.5.1.1
• IP Statistics: Bcast: Sent: Object = f10BcastPktSent, OIDs = 1.3.6.1.4.1.6027.3.3.5.1.2
• IP Statistics: Mcast: Received: Object = f10McastPktRecv, OIDs = 1.3.6.1.4.1.6027.3.3.5.1.3
• IP Statistics: Mcast: Sent: Object = f10McastPktSent, OIDs = 1.3.6.1.4.1.6027.3.3.5.1.4
• ARP Statistics: Rcvd: Request: Object = f10ArpReqRecv, OIDs = 1.3.6.1.4.1.6027.3.3.5.2.1
