PPP Troubleshooting
7-8
Once a connection is made, problems may be monitored using the Show/Monitor/List Ports command.
The following table explains the counters useful for PPP troubleshooting.
Table 7-1: Port Counters
Counter(s) Information Displayed
Packets Input Packets from the remote host to the SCS.
Packets Output Packets from the SCS to the remote host.
Packet-Too-Long Number of packets longer than the Maximum Receive Unit (MRU)
negotiated with LCP. In most situations, this counter will be 0. To
correct this error, the remote node should configure a smaller
Maximum Transmission Unit (MTU).
Bad FCS (Frame Checksum) Number of corrupted packets. This problem may be due to line noise,
flow control problems, and so on. This number should be less than
1% of the Packets Input counter; if it is not, performance is suffering
greatly.
