For example, a runt, giant, or an FCS-Err does not increment the rcv-err counter. Use theshow interfaces fastEthernet 6/1 statuscommand to display this: Last input, output - The number of hours, minutes, and seconds since the last packet was successfully received or transmitted by the interface. An alternative to this command (for Catalyst 6000, 4000, 3550, 2970 2950/2955, and 3750 series switches) is theshow interfacescard-type counters errorscommand which only displays the interface error counters. Try to find the offending device and remove it from the network. It is counted with short traffic bursts flow when some packets fill this buffer. /iaPath () This example of the show interface command shows theLast input neveron the TenGigabitEthernet1/15 interface. The mode-conditioning patch cord prevents the over use of the receiver for short lengths of MMF and reduces differential mode delay for long lengths of MMF. Refer to theCatalyst Switch Cable Guide. The total number of frames whose first transmission attempt was delayed, due to traffic on the network media. If this counter increments, it is an indication of a wiring problem, an excessively loaded network, or a duplex mismatch. I have a port that I believe is going up and down on a 2960X-port switch. The current implementation of SSH supports version 1, both the data encryption standard (DES) and 3DES encryption methods, and can be used with RADIUS and TACACS+ authentication. This is not available on all IOS versions. Common Causes: This error can indicate a duplex mismatch among other things. endobj To display the MAC address for a specific port, perform this task in privileged mode: Display the MAC address for a specific port. When a layer 3 interface is connected to a layer 2 switchport, it is not able to interpret these frames, which results in Input errors, WrongEncap errors, and Input queue drops. Use theshow interfaces counters errorcommand to look at OutDiscards. For a 10 Mbit/s port this is later than 512 bit-times into the transmission of a packet. This chapter describes how to check switch port status and connectivity on the Catalyst enterprise LAN switches. Description:show interfacesand show interfaces counters errors.
