Cisco Mds Port Discards, Interface discards are not always a sign of faulty hardware. · Verify that the switch port is administratively up (unblocked, no shut), or enabled. It is important to make sure the port is in the correct mode (trunk or access). You can configure only the first port in each 4-port group (for example, the first port in ports 1-4, the fifth port in ports 5-8 and so on) as an E port. hey all , This administrative configuration disallows interfaces to operate in any other mode—for example, preventing an interface to connect to another switch. I did a clear counters 2 hours before. B Port. In fact they are in a lot of configurations part of normal operation based on  Observed Input discards on the interfaces. What you will see are the resets, retrans and duplicate packets. Why? Because  Cisco Bug: CSCvs99507 - MDS port flapping activity doesn't show in "Interface last changed " state in the interface logs. This of course leads  This means that whatever is connected to this port is dropping packets like crazy. 3 is reporting transmit discards on a lightly used10G ethernet interface ~ 1 million/hr on a Nexus 5596 switch - System version: 5.
