Interface NNI Counters

Definations

• rmon – The Remote Network Monitoring (RMON) MIB that supports monitoring and protocol analysis of local area networks (LANs).
• phy – Monitors the Ethernet transceivers that are used for Ethernet interfaces that handle the analog to digital conversion of Ethernet ports.

The configuration of NNI Counters is defined as follows:

        • Pkts65to127-octets – The number of transmitted packets with 65 to 127 bytes in them.
        • Pkts128to255-octets – The number of transmitted packets with128 to 255 bytes in them
        • Pkts256to511-octets – The number of transmitted packets with 256 to 511 bytes in them
        • Pkts512to1023-octets – The number of transmitted packets with 512 to 1023 bytes in them. 
        • Pkts1024to1518-octets – The number of transmitted packets with 1024 to 1518 bytes in them
    • In-errors – Count of received packets that were errored.
    • Out-errors – Count of transmitted packets that were errored. 
    • In-discards – The count of received packets that were discarded. 
    • Out-discards – The count of transmitt packets that were discarded.
    • Phy-stats –  Container
      • Rx-runts – The number of packets that are undersize (less than 64 bytes), these packets are typically discarded. 
      • Rx-oversize-packets – The count of packets that were received that were longer than the interface MTU
      • Rx-fragments – The number of received packets that are fragments.
      • Rxjabbers – Count of packets where the adapter was found to be continuously sending data or sending greater than the MTU. 
      • Carrier-sense-errors – Count of packets or occurrences where carrier on the ethernet signal could not be detected. 
      • Alignment-errors – Received ethernet frame’s length is not a multiple of 8 bites (a byte) and it has a bad FCS. 
      • Fcs-errors – A count of frames that were discarded due to the calculated frame check sequence not agreeing with the one sent in the packet indicating and errored packet. 
      • Symbol-errors – Errors that occur when the receiving device detects undefined or invalid symbols during data transmission suggesting a problem with the physical medium, connection or transceiver
      • In-pause-frames – The number of times a pause frame was received. 
      • Out-pause-frames – The number of times a pause frame was sent out of the port. 
      • Deferred-transmissions.– The number of times that a packet had delayed in transmission due to a collision on the port
