RE: Palo Alto 5450 and NAT

Ugh. That sounds like a real PITA. Frustrating that they won't solve it. Been there. We have PAs, but we don't NAT as much and haven't run into this problem. It does sound very uncommon. I hate to say it, but static NATs for the problem hosts you find? It sounds like you are handy with a script, perhaps ...

RE: Arista?

Northwestern had Arista's in our DC for a while. Hardware-wise they were excellent, no issues. They were also very stable, software-wise. However, we were not particularly impressed with Cloudvision, their management platform. This was more due to our deployment model. Cloudvision is really great ...

These are good points Jeroen. We have been utilizing delegation in the Infoblox for longer than I can really remember. 15 years? Maybe more. This is part of how we are saving so much time. I didn't have to spend any consulting dollars on this, though. Very easy to get the delegation setup in IB. Are ...

Thanks for the excellent details Andy, very informative. Honestly, Infoblox is the same for pricing – you pay per appliance, even with an active/standby HA pair. Infoblox is not cheap. But I no longer pay for one FTE to do DNS/DHCP manage. And that was when I had a total of 2 pieces of hardware to support. ...

Measuring Multicast Usage?

Posted By Chris Fabri 07-14-2022 12:49:28 PM
Found In Egroup: Network Management \ view thread
Does anyone have a good system for measuring multicast usage? We'd like to get a better handle on what's going on with multicast, and it's proving to be more challenging than expected (and we expected it to be a bit of a challenge!). It looks like flows aren't going to be helpful, as you need to coordinate ...

This has been my experience with PA vs Juniper at least. Same price up front, and in our case PA wasn't more or less expensive ongoing. What I've seen over the last 5 years is that PA support costs go down for the current hardware you have, and then when they introduce new hardware, cost-wise it slots ...

Are you sure on that PA vs Cisco pricing? For PA, you get a GP license, and it's only limited by hardware - no user-based licensing. Cisco was per-user licensing, and when I did it, confusingly so. I think you can make the AnyConnect license cheaper, but you're bending the rules a little.

Heh. Since my first reaction was "you can do this!?!" I googled it. I hadn't even thought of trying to use bots to make this work, although it sounds more convoluted. Zapier also came up, which you'd have to pay for. Maybe this isn't as ridiculous as it sounds. :)

I'm in 6 different Slack, uh, teams? Only a few of them have much traffic. I don't have Slack sending me notifications (I'm using a Mac), so it's more that I sort of look for badges.

This. Outlook at least is incapable of threading the replies. It makes it much more difficult for me to follow an email conversation.

F5 and ACI - how are you doing failover?

Happy Holidays everyone! Northwestern has been working through some issues with our F5 infrastructure (TMOS v13) that is connected to Cisco's ACI (v4.2). Specifically, failover between an active/standby pair of vCMPs in a VIPRION chassis. Looking for anyone who's had issues with failovers. We had ...

Late to the party on this thread! Julian mentioned that we went to wired on-demand, and Richard brought up users "voting with their feet." Julian didn't mention that our wired dorm utilization was extremely low - like we could accommodate all the wired usage on campus on a /24, with 6500-something ...

Thank you everyone for the feedback - I do apologize. My first reply was definitely negative and inappropriate. I had a personally negative initial reaction to what felt to me like a "political" argument about eduroam, but that was not a constructive response and not warranted.

It's very easy to start a new thread, and that makes it easier for other people to find the conversation, as well as getting more engagement if someone is just skipping over the thread or doesn't return to it because it's not relevant to them.

Thanks everyone for the feedback. We've tried having folks remove our "Northwestern" SSID with some success, but to Julian's point our users have conflated all these various issues, so telling them to remove Northwestern may have some resistance. But this may be something we look to find other ways ...
