Monitoring Error Counters

Error counters are monitored to make sure they are not increasing rapidly, because a rapid increase indicates a problem. For information about troubleshooting these problems, refer to the troubleshooting information for the appropriate protocol. You can monitor error counters in one of the following ways:

• By using MONITOR to view counters such as Checksum Errors, Send and Receive Packet Errors, and interface-specific errors. To view these counters, load MONITOR and follow this path:

  Select LAN/WAN Information > interface you want to view

• By using PPPCON to view the following PPP counters:
  • Bad Address Fields
  • Bad Control Fields
  • Bad FCS Values
  • Packets Too Long

  To view these counters, load PPPCON and follow this path:

  Select PPP Interfaces > interface you want to view > PPP Error Statistics

• By using IPXCON to view the following IPX counters:
  • Too Many Hops
  • Header Errors
  • Unknown Sockets
  • Decompression Errors
  • Malformed Requests
  • Compression Errors
  • Open Socket Failures
  • Maximum Sockets

  To view these counters, load IPXCON and follow this path:

  Select IPX Information > Detailed IPX Information

• By using TCPCON to view the following TCP/IP counters:
  • IP Errors
  • IP Address Errors
  • Unknown Protocol Errors
  • Local Errors
  • Reassembly Failures Detected
  • Fragmentation Failures Detected

  To view these counters, load TCPCON and follow this path:

  Select Statistics > IP > More IP Statistics

• By using ATCON to view the following AppleTalk counters:
  • Bad DDP Length
  • Bad DDP Checksum
  • No Route Found
  • Too Many Hops

  To view these counters, load ATCON and select Packet Statistics.
