I recently upgraded a switch stack from 03.07.04.E to 16.3.7 due to a number of bugs on the previous firmware, including high CPU utilization. I checked our monitoring software (Orion) after the install, and found that CPU #3 was still at 99%. Using the command 'show processes cpu' does not show that the CPU is being taxed. CPU utilization for five seconds: 15%/8%; one minute: 16%; five minutes: 16% Switch Ports Model SW Version SW Image Mode ------ ----- ----- ---------- ---------- ---- * 1 34 WS-C3850-24XS 16.3.7 CAT3K_CAA-UNIVERSALK9 INSTALL 2 56 WS-C3850-48U 16.3.7 CAT3K_CAA-UNIVERSALK9 INSTALL 3 56 WS-C3850-48U 16.3.7 CAT3K_CAA-UNIVERSALK9 INSTALL It appears it is measuring the CPU for switch 3. First, I was under the impression that all of the processing was performed by the stack master. Why would switch 3 have high CPU usage? Second, is there a way to get more diagnostics on switch #3 regarding CPU usage?

I am working with a client on troubleshooting an issue with a Nexus 9K. Seeing as I do not have direct access to the device, I had him run 'show tech-support' to get all of the information on the device. On other devices, this makes a large, but manageable text file to get information from. From the 9k, the file was 2.3GB extracted! This is too large of a file for any text editor to handle. What is the best way to get diagnostic information from this?

As the title says, a switch is receiving pause frames, but the ASA is still getting overrun errors. We have played with the settings for flowcontrol, but nothing seems to stop these errors. I have performed troubleshooting as per this document:
https://www.cisco.com/c/en/us/support/docs/security/asa-5500-x-series-next-generation-firewalls/115985-asa-overrun-product-tech-note-00.html#anc6
There does not seem to be any significant resource hogs, Is there a misconfiguration on one of the devices? I am trying to find out what will fix the overrun issue. What else should I try?

I have a 2960 that has high CPU utilization. I know the " Hulc LED Process" processor usage is caused by a glitch, but what about the spanning tree CPU usage? There are 176 VLANs running on this switch, and it is running Rapid PVST+. Is that typical CPU usage for this kind of switch running that many instances of spanning-tree?
The CPU utilization is as follows:

I am working on a ISR4431 that is running Cisco IOS XE Software, Version 16.03.06. For some reason, SSH version 2 will not activate on it.
I get an error message stating that I need to generate keys greater than 768 bytes for SSH version 2 to work. I have generated keys that are 4096 bytes in length. There are definitely keys in the key store, but for some reason they are not used. Am I not generating the correct type of key? What is the command looking for?

I am upgrading a 2504 WLC from 8.3.132.0 to 8.3.141.0. I am following the directions that are listed here: https://www.cisco.com/c/en/us/td/docs/wireless/controller/release/notes/crn83mr4.html
Step 4 mentions this:
Step 4
(Optional) Disable the Cisco WLC 802.11a/n and 802.11b/g/n networks.
Note
For busy networks, Cisco WLCs on high utilization, and small Cisco WLC platforms, we recommend that you disable the 802.11a/n and 802.11b/g/n networks as a precautionary measure.
Is it suggesting turning off the radios for the duration of the install, or shutting down the networks in the menus at "Wireless -> 802.11a/n/ac -> 802.11a Network Status" in the GUI? What is this precautionary measure preventing?
