A high number of CRCs is usually the result of collisions or a station transmitting bad data.įrame errors are bad frames that have packets with an incorrect length or bad frame checksums. If the frame is altered between the source and destination, the ASA notes that the CRC does not match. This CRC is generated from an algorithm based on the data in the frame. When a station sends a frame, it appends a CRC to the end of the frame. Other input-related errors can also cause the input error count to increase, and some datagrams might have more than one error therefore, this sum might exceed the number of errors listed for the types below.ĬRC errors are the number of Cyclical Redundancy Check errors. Input errors are the number of total input errors, including the types listed below. For example, any Ethernet packet that is greater than 1518 bytes is considered a giant. Giants are the number of packets that are discarded because they exceed the maximum packet size. They might also be caused by poor wiring and electrical interference. Runts are the number of packets that are discarded because they are smaller than the minimum packet size, which is 64 bytes. The number of broadcast packets received. The “no buffer” indicates the number of failures from block allocations. The number of packets and bytes received on this interface. This is the interfaces IP address and subnet mask. If the interface name is not set the MTU will display “MTU not set”.
SHOW INTERFACE ERRORS CISCO COMMAND MAC
This is the interfaces MAC address and configured MTU. On a multi context firewall, in the system context you might see the following message: Available for allocation to a context If an interface is a member of a redundant interface, you see the following message: Active member of Redundant5 If you do not configure a name, you see the following message: Available but not configured via nameif If the line is up the negotiated or actual values will be in parenthesis. If the line is down, the configured values are displayed.

Interface GigabitEthernet0/1 "inside", is up, line protocol is up The Output of "show ethernet-switching interface" is also different to "show ethernet-switching interfaces".USS-ASA/pri/act# sh int GigabitEthernet0/1 Thanks for the fast response and modification, but it doesnt work.
