I was more focused on the output of this command "show processes cpu platform sorted | inc wncd" looking at the cpu utilization. I was trying to see if I could balance it there. Also, I should mention we are on 17.3.7 code stream. Don Sullivan Network Administrator Information Technology 205-726-2111 ...

Yes, pretty much for each building. I do group some together if the total does not exceed 250. Its not totally balanced out, but fairly close. I do not have the number of APs you are dealing with (1570) so not sure if that might be a factor. Don Sullivan Network Administrator Information Technology ...

I set the limit for my site tags at 250 APs. I observed when I broke my site tags up by buildings the cpu utilization was much more manageable. I did this also at the time they were working the wncd issue as a work around since I was running the 17.3.5b code. Don Sullivan Network Administrator Information ...

We do a captive portal on out guest SSID but only so they can see the disclaimer that they can get kicked off if their device becomes a bad actor. Once they click the accept they are on the network. We limit the device connectivity time to 8 hours then they have to sign in again. Don Sullivan Network ...

I have been tasked to look into implementing wireless client isolation. From a Cisco perspective, this looks like enabling P2P Blocking action under the WLAN configuration. I wanted to see if anyone on the list had implemented this feature and see if you would be willing to share what outcomes you saw ...

Jeff, Thanks for the feedback from Cisco. I will add my request to the ticket I opened to not exclude the clients but still limit the arp. Don Sullivan Network Administrator Technology Services 205-726-2111 | office dsullivan@samford.edu LinkedIn www.samford.edu 800 Lakeshore Drive Birmingham, ...

TAC expressed the same concerns for me concerning this bug and has me monitoring the cpu processes for wncd. The RA traces I sent to them was showing the client dropping because of being blacklisted for excessive ARP which led me to checking the exclusion table and I was seeing a number of devices with ...

With the start of the new semester, we have had a significant number of complaints concerning connection drops where the student says their wifi connection is dropping and taking some time to reconnect. We just upgraded before the kids started coming back on campus to 17.3.5b (Cisco 9800 controller). ...

Jason, With the hospitality APs, the new dorm construction has been getting one cable pulled per room for the access point (although since the APs now have a passthrough port, we will probably run 2 cables per room to utilize that feature). Don Sullivan Network Administrator Technology Services ...
