You see the debug output but the output scrolls past faster than you can read. Last Modified. The port was on a Cisco Nexus 5000 series device and I could see that, while output errors were clocking up at a massive rate, the switch was giving me nothing to go on as to what kind of errors they were. The HP switches don't see anything wrong with that, but the Cisco L3 backbone switch sees the node2 lan900 MAC address jumping back and forth between the two switches and does not like it too much. 0 output buffer failures, 0 output buffers swapped out. 0 output buffer failures, 0 output buffers swapped out From the output above I can see that the interface is configured as half duplex and 10Mb. py, but when attempting to use multiple MIB names converted to. Experts Exchange. We recently replaced several Cisco 2960s with 3850 stacks. Switch#show interface Or Switch#show interface 26003 bytes, 0 underruns 0 output errors, 0 collisions, 9 interface resets 0 babbles, 0 late collision, 0 deferred 0 lost carrier, 0 no carrier, 0 PAUSE. This is made possible through the use of Xian Network Manager, the platform that runs the Smart Management Pack; no complicated programming or scripting is needed. HS link CRC errors Count of errors on the high-speed links between the ASICs responsible for handling the router interfaces. The default is local7.
