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 Troubleshooting. 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 ATCON to view the following AppleTalk counters:
  • Bad DDP Length

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

• 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:
