SG220 with Cisco 2602 and 2702 APs - Interface input errors - throttles - CDP disappearing
I have a few SG220 switches with code 18.104.22.168 and ports are show input errors and throttles on ports connected to APs. I am seeing it impacting wireless connectivity as well connected to Cisco 2602i and 2702i APs running 22.214.171.124.
I believe this may be related to Cisco Bug ID -CSCuy16641 -
I see there is no official workaround but this is effecting multiple locations of a new implementation. Any assistance would be helpful.
Here is what I see from the switch port - show interface gi 1
Hardware is Gigabit Ethernet Auto-duplex, Auto-speed, media type is Copper flow-control is off back-pressure is enabled 1355 packets input, 232707 bytes, 211 throttles Received 157 broadcasts (111 multicasts) 0 runts, 0 giants, 211 throttles 211 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored 111 multicast, 0 pause input 0 input packets with dribble condition detected 7407 packets output, 872264 bytes, 0 underrun 0 output errors, 0 collisions, 0 interface resets 0 babbles, 0 late collision, 0 deferred 0 PAUSE output
I tried disabling back pressure - setting speeds down to 100 Full. Even used a know good patch cable directly to the AP as to eliminate cabling errors. I am seeing this result on ALL of my SG220 switches that have APs on them. I have these APs setup on SG500 and SG300 series switches in this environment and no issues. Only looks like the SG220s.
