If the problem appears to be local, use the debug serial interface privileged EXEC command. I had two serial E1 connections that were presenting CRCs at both ends. The number of failures represents the number of packets that have been dropped due to buffer shortage. the old emulator did not work on this platform so i got VSPE and can run both at the same time. my review here
Events Experts Bureau Events Community Corner Awards & Recognition Behind the Scenes Feedback Forum Cisco Certifications Cisco Press Café Cisco On Demand Support & Downloads Login | Register Search form Search If you suspect faulty router hardware, change the serial line to another port. A program should expect that the CRC won't always check out, and should handle that. Clocking Overview The CSU/DSU derives the data clock from the data that passes through it.
Do about 200 pings with a packet size of 2000 if 56kb and the maximum amount if a T1. You can check the framing format of the controller from the running configuration or the show controller t1 command output. If it was just flat out wrong, then ALL the archive data packets from VVP would have bad CRC values. For example, if errors occur at a consistent interval, they could be related to a periodic function such as the sending of routing updates.
bytes Total number of bytes, including data and MAC encapsulation, in the error-free packets received by the system. If the electrical interface is displayed as UNKNOWN (instead of V.35, EIA/TIA-449, or some other electrical interface type), an improperly connected cable is the likely problem. I don't know where it came from. Davis Vantage Pro2 Communication Protocol You can also check the microcode version to see if it is current.
Any ideas?? Usually the line is the source. Figure 15-9 illustrates the basic topology of the CSU/DSU local and remote loopback tests. Serial x is down, line protocol is down (DTE mode) Typically indicates that the router is not sensing a CD signal (that is, CD is not active).
This overrides any hold queue specification included in your configuration. Davis Vantage Pro Manual Version 5.8.0 Features 1. i am using VSPE because i am also running virtual weather station at the same time. I will be testing without VSPE to see if there is a difference.
port-adapter -Refers to the appropriate hardware manual for information about port adapter compatibility. :t1-channel -Optional. check this link right here now Can now browse and make plots if serial connection not present (previous versions exited after error). 3. Crc Errors On Serial Interface Figure 15-6 and Figure 15-7 illustrate two useful ping tests, an all-zeros (1500-byte) ping and an all-ones (1500-byte) ping, respectively. Davis Weather Api Detailed Information on the show interfaces serial Command The following sub-sections cover the show interfaces serial command's parameters, syntax description, sample output display, and field descriptions.
When traffic is light, there is no problem. Make certain that the cables are within the recommended lengths-no more than 50 feet (15.24 meters) or 25 feet (7.62 meters) for a T1 link. Do not let them loop the CSU toward the ckt. The CRC is probably wrong too. Davis Vantage Pro2 Software
Microsoft Word doesn't come in a Linux version! On a serial link, CRCs usually indicate noise, gain hits, or other transmission problems on the data link. Figure 15-2: show controllers cbus Command Output On access products such as the Cisco 2000, Cisco 2500, Cisco 3000, and Cisco 4000 series access servers and routers, use the show controllers If input errors are high while interface resets are increasing, the problem is probably a bad link or bad CSU/DSU.
Serial Lines: Increasing Input Drops on Serial Link Input drops appear in the output of the show interfaces serial EXEC command (see Figure 15-1) when too many packets from that interface Weatherlink Data Logger If you suspect faulty router hardware, change the serial line to an unused port. Driver will be restarted automatically and a note will be put into the View Log fie.
Then they put on the Cisco stuff and there they are. For information on correcting timing problems, see the section "Troubleshooting Clocking Problems," earlier in this chapter. On each update, the new data is stored using the pointer to index into the circular buffers and then the pointer is incremented modulo 24. Weatherlink Ip A problem was corrected that was causing WeatherLink to crash when a user added a note to the browsed data.
collisions Number of messages retransmitted due to an Ethernet collision. Note:The ping command is particularly useful when high levels of input errors are being registered in the show interfaces serial display. Inside are three .doc files including the protocol document. It's been running for about 8 hours now and I haven't seen the problem.
Humidity now displays correctly on weatherlink.com when using a Monitor II and a WeatherLink Network Annual Subscription. I tried to extend the cable length at one end and the CRCs decreased. What's new in 6.0.0 Supports uploading to WeatherLink.com when used with a WeatherLink Network Subscription. in free list- Identifies the number of buffers currently in the pool that are available for use.
NEXT_DAY_PTR. when downloading from the station i am getting "crc error". Using the show interfaces serial EXEC command, determine if the line protocol remains up with the status line indicating "Serial x is up, line protocol is up (looped)," or if it Ensure that all devices are properly configured to use a common line clock.
For more information, consult the documentation for your CSU, DSU, serial analyzer, or other equipment.

She went into WeatherLink and changed the Communications port to COMM 1.
Did you try the diagnostic that I suggested? The next download attempt does not have to start over from the beginning. Fixed the "Unable to copy log file" pop-up error when logging messages. 2. The controller is administratively down when it has been manually shut down.
A lot of times, they will loop the router's CSU toward them. With year 2000 as the base, things run much better.
