Hi The counters will show whats received and sent and how there talking , if 1 side is lot less than the other theres an issue there , ive had issues with devices not sending packets back to to the other unit even when configured correctly or only sending some if its working in ON state the issue is to do with the negotiation between the devices if there configured right , i cant tell whats wrong from that debug theres nothing valid in it to pull from if the customer wants it on LACP tell them to put it back so you can troubleshoot it and fix it , or tell him you'll change your side to match ON ,you cant be expected you to fix something you cant troubleshoot all mac zero usually mean bad NIC but i dont see anything in your outputs to show where or how that was seen to say for certain , example of counters packets should match nearly between both sides LACPDUs Marker Marker Response LACPDUs Port Sent Recv Sent Recv Sent Recv Pkts Err --------------------------------------------------------------------- port-channel1 Ethernet1/45 680037 680035 0 0 0 0 0 Ethernet1/46 680037 680034 0 0 0 0 0 Ethernet1/47 680038 680035 0 0 0 0 0 Ethernet1/48 680040 680033 0 0 0 0 0 ...

it maybe hardware as Leo said or could have just totally corrupted the image in flash and wont boot it right , if there is another image in its flash you could try boot that from rommon instead or try and boot the switch from USB as another option bypassing local flash There 2 things id try , if they fail to get it working i would RMA it TAC may get you to try a method anyway before rebooting ...

Hi it doesnt support ISE show techs at all , maybe in the future e Cisco CLI Analyzer is a smart SSH/Telnet client designed to help troubleshoot and check the overall health of your supported device. Features include: ASA, IOS, IOS-XE, and IOS-XR System Diagnostics—Utilizes Cisco TAC knowledge in order to analyze the ASA and detect known problems such as system problems, configuration mistakes, and best practice violations. ASA Traceback Analyzer—Attempts to match the root cause of a crash to a known bug if the ASA has experienced a system traceback. If a match is found, the ASA version or versions in which the bug is fixed are provided. ASA Packet Tracer—Allows administrators to send simulated packets through the ASA as a test. If the packet is dropped, the ASA configuration portion or feature that could have contributed to the packet drop is identified. ASA Firewall Top Talkers—Identifies the connections that pass traffic through your ASA that have the highest bit rates. Contextual Help and Highlighting—Provides information based on command outputs in an interactive way. Highlights enable real-time search capabilities in the console window. ... View more

Thats normal SVIs as Joseph stated ICMP is not prioritized in the backplane so the anything could be hammering it on the backplane and causing flutuations in responses If you want to fix it , apply priority to the ICMP packets or ,use a proper test method like IP SLA or end to end testing , pinging a virtual interface with non prioritized packets you will never be guaranteed accurate results ,you could use CoPP if supported ...

You could use ACLs and prevent radius traffic from talking out any other port than the G0/0 mgmt , thats how we did it for our MGMT protocols to lock them down to 1 port Theres is feature called MPP too that forces certain MGMT traffic out its port this in IOS-XE but i dont think its available in 38s only ISRs IOS-XE ,i dont see any option for radius/tacacs either even in that so maybe the option to get it work (config-cp-host)#management-interface gigabitEthernet 0 allow ? beep Beep Protocol ftp File Transfer Protocol http HTTP Protocol https HTTPS Protocol snmp Simple Network Management Protocol ssh Secure Shell Protocol telnet Telnet Protocol tftp Trivial File Transfer Protocol tl1 Transaction Language Session Protocol sounds like something else could be causing it though , are these switches in same policy grouping as the working ones in your ISE or Radius server whatever your using to authenticate , authenticating should have no effect on routing to an already reachable server , unless something is being pushed from the radius to the switch and causing it ? ...
