An administrator might crc errors cisco fiber notice errors reported in the show interface command output on the Adaptive Security Appliance (ASA). Prerequisites Requirements There are no specific requirements for this document. Components Used This document is not restricted to specific software and hardware versions. The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command. Problem The ASA interface error counter "overrun" tracks the number of times that a packet was received on the network interface, but there was no available space in the interface FIFO queue to store the packet. Thus, the packet was dropped. The value of this counter can be seen with the show interface command. Example output that displays the problem: ASA# show interface GigabitEthernet0/1 Interface GigabitEthernet0/1 "inside", is up, line protocol is up Hardware is i82546GB rev03, BW 1000 Mbps, DLY 10 usec Full-Duplex(Full-duplex), 1000 Mbps(1000 Mbps) Input flow control is unsupporte

When one site of a link is configured on full-duplex and the other on half-duplex you will see the CRC errors at the interface which is configured on full-duplex. This problem occurs also when one site of a link is configured on auto-duplex and the other fixed (full-duplex). Duplex mismatches caused very big performance problems, so be very sure both sites of a link are configured the same. Vulnerability Announcements Field Notices

CRC errors confirms that a frame error has occured, but what about "input errors"? cisco interface share|improve this question asked Dec 19 '14 at 17:15 Birdman 162117 add a comment| 2 Answers 2 active oldest votes up vote 3 down vote accepted The "input errors" counter will increment whenever the interface receives a frame with any sort of input error, which includes CRC among other types of errors. Each frame is only counted once, no matter how many types of specific errors it contains. You can see an example of this if you check this recent question which also has input errors. share|improve this answer edited Dec 19 '14 at 21:01 answered Dec 19 '14 at 17:25 YLearn♦ 15.3k43273 add a comment| up vote 4 down vote See this page, table 4-6: http://www.cisco.com/en/US/docs/internetworking/troubleshooting/guide/tr1904.html Description of input errors from that page: Includes runts, giants, no buffer, CRC, frame, overrun, and ignored counts. Other input-related errors can also cause the input error count to be increased, and some datagrams may have more than one error; therefore, this sum may not balance with the sum of enumerated input error counts. share|improve this answer answered Dec 19 '14 at 17:28 pfa 1412 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using
