Info Sec reviews and advises, network admins build and manage the cloud network infrastructure here. All the VPC, VNET, V etc., subnet/IP selections, networking plumbing via Internet2 Cloud Connect/IPSEC, etc. as well as firewall bits. For us, we follow the same model on prem as cloud – force ...

We just learned last semester nearly none of the online games were playable. Thanks to a ticket we made an adjustment that resolved / improved it greatly. We NAT on Palos and had been doing dynamic IP and port (source range of IPs with an oversubscription rate). Games didn't like that but adjusting to ...

RE: What are you using for packet brokering and packet capturing

I only want to comment to say I believe Extreme, Cisco and Juniper all do RSPAN remote mirroring across their fabrics. We are Extreme so with SPB I can mirror packets from anywhere in the network back to a server to observe without the expense of packet brokers. You might want the visibility for NDR ...

RE: Twilio Alternatives for ClearPass, Meraki Specifically

Lee, We are Twilio from Clearpass for guests (~600 / day) and from our monitoring platform for IT folks. We haven't been having trouble but we sure do spend a bunch of effort reading all the A2P guidelines and following some international actions when recommended (going through a registration process). ...

We are signing the LRSA prior to end of year cut off. I don't think it affects our ability to sell the IP resources later but I'm not lawyer. We're saving $8k/year by signing but I'm glad Chuck mentioned it cause market is something like $2.7M for a /16 at the moment. I hear to expect it going higher ...

RE: wide-spread jumbo deployment

Found In Egroup: Network Management \ view thread
Nope. We've reviewed it plenty of times for different individuals and always land on it isn't worth it cause we're surely going to loss track and isolate traffic flow between systems somewhere down the road. That said, jumbo frames are in use within a couple specific vlans that we don't route (HPC cluster ...

RE: Publicly Accessible Monitoring Tools

We consider IP addressing confidential and we don't have monitoring accessible without auth. We just migrated to Zenoss Cloud and are starting to tweak things to improve visibility under a few circumstances that are currently gaps (like total outage kind of situations). Adam

In the trial we expanded to a few more buildings and then ended the trial and turned it down. It seemed to just work for us. We'll enable it once it's generally available. Adam

RE: Network Segmentation using VxLAN or VRFs

Another Extreme shop here, so SPB fabric with a bunch of VRFs all pushing through firewall to get anywhere. Staff, student, guest, environmental, etc. Works superbly for us for several years now. Very easy to support. The only debate we have is whether a new thing is worth the couple of hours to stand ...

RE: Microsoft Express Route

Found In Egroup: Network Management \ view thread
We've been using Azure Express Route for most of the year. It's the primary path and IPSEC tunnels back it up. I like it a lot. Keeps our traffic off commodity internet pipes but then this is not lots of traffic and commodity internet pipes have been very reliable. I'm not remembering any extra I2 costs ...

We have been in beta program for Passpoint / HOTSPOT 2.0 with Aruba. I don't have much to say about it except that it seems to just work in one busy building on campus. It's a long running beta so I'm interested to see it move further to production (and for Verizon to be supported). Adam

We are just barely starting the replacements but out of ~70,000 the biggest winner is Housing. We just disconnected ~5,800 jacks (the ones in the Residence Halls where it was one jack per bed). They only had ~80 things plugged in since last fall (mostly Xbox and PS5s but just a few PCs, all stuff that ...

Lee, We've been running a model with flat rate install fees and monthly charges and $0 budget dollars to us for 15+ years now. We adjust the rates annually based on actual expenses. We cover costs and appropriate lifecycle replacements but collect no profit whatsoever naturally. Under that model folks ...

I hope someone with more experience than me chimes in but we've done a bunch of that over the last couple years. We learned as we built so I'd likely build it from scratch slightly differently but I can advise what we do. Don't consider any of this best practice. My only tip is if you have the time, ...

I don't code my own so I don't have that expense. I stopped tracking my savings ~5 years in when I surpassed half a million dollars. It's definitely cheaper (it's otherwise not better, it's identical and cheaper). Adam
