RE: Odd issue with DHCP and Intel adapters

All I wanted to send a follow up on this one. It seems this issue is related to "Modern Standby" power save mode on our managed Dell laptops though we see the issue on some non-managed non Dell laptops. When the lid on the laptop is closed the issue starts immediately and continues for about 45 ...

Hi TJ There is no option 26 being sent in the ACK so I don't think it applies. Thanks for the suggestion. Patrick

Hi Lee Aruba platforms 8.10.0.9 and 10.4.0.2. At least the few clients I spot checked and are generating the DHCP traffic were on both platforms. Patrick

Odd issue with DHCP and Intel adapters

Hi all While investigating a separate issue we discovered hundreds of wifi devices, all Intel adapters, in a continuous DHCP Request/Ack loop. It's about 400-600pps of DHCP broadcast traffic. We are trying to gather info from the team that manages our client endpoints on driver versions and if there ...

We have been running a pair of Fortigate firewalls in front of our wireless clients for 10 plus years. We peaked at just over 45,000 concurrent connections before Covid hit. We run both ipv4 and ipv6. We syslog all ipv4 nat connections for DMCA and other security related events. We use the Fortigate ...

Hi Chintan I got this from our wireless folks that actually know what was going on 😊. 8.10.0.9 seems to have resolved it, we no longer see radio resets. We have observed this problem in Harvard's AOS 8 environment, specifically on AP-530 and AP-655 platforms running 8.10.0.7. ...

HI Chintan We upgraded to 8.10.09 on 11/29 to address the radio reset issue that was mentioned on another thread on this list. So far, we have no issues to report. Regards Patrick Harvard University

Ryan We have a small footprint of Citrix Netscalers after Cisco exited the space. We are not doing anything very taxing or advanced with them. I would echo Eric's comments. They have been set it and forget it. Any required upgrades have been rare but straightforward to do. It's been a very long time ...

+1 for Twillo. We set it up for guest access maybe 5-6 years ago and have never logged in since. It can add up, we are running about $1,000 a month for SMS costs. Patrick

We had our HP orders set to "ship complete" so that everything came on pallets shrink wrapped for each order. The problem was HP were never able to have everything available to ship at the same time so the distributor would use our gear to fulfill other orders. We changed to partial ship and gear started ...

Hi all We just received our renewal for Securew2. It is up 17.4% over last year and that was up 12% from the year before. Are others seeing the same levels of price hikes? What are you using for 802.1x client-side configuration that includes EAP-TLD that's not Securew2 and would you recommend it? ...

Hi there Do you put your ClearPass servers under RFC1918 or global routable network spaces? If the servers are using RFC1918 addresses, how do they reach out to the Aruba cloud for periodic updates? We used RFC1918 addresses for ipv4. We have a NAT rule on a firewall to allow them to phone home to ...

We have used WTI forever. They do what we need them to do. We just started to use their cellular based term servers which are working well. For USB based ports we used the REM-4R0 with a USB hub to expand the port count. https://www.wti.com/collections/console-servers

Hi all I checked with our Aruba SE. Passpoint will transition away from using Clearpass (@Ryan Turner, they must have heard you load and clear) to using CloudAuth in an Aruba Central instance. You do not have to be all-in on Aruba Central, you just need to leverage the CloudAuth function as the radius ...

We update the expiration time to +400 days every time the device authenticates to the network. This way the network self purges devices that are no longer on the network. That worked great until Covid when many devices were powered off or taken home. Before the 400 days we used the API to extend the ...

My only input would be to investigate ArubaOS 8.9.0.1. From what I understand there was a lot of focus on improving the scaling of the AirGroups functions in this release.

+1 for the old listserv. We are in a similar boat. Verizon is full force with their "network transformation" to basically dump their copper network. We have a few thousand analogue lines used for elevators, emergency blue phones, OT, alarms, lobby phones, etc. We are starting to look for alternative ...
