Re: Sites unreachable while traversing Dallas IXP
by Mel Beckman 26 Sep '25

Nick, I agree that theoretically there should be no problem with different hashing implementations on each end, but as I noted in my original answer, I have directly experienced issues like packet reordering and dropped packets. Perhaps this was due to a bug of some sort in one of the implementations. I do know that changing ONLY the algorithm on one end solved the problem. Once I found a working configuration, I simply noted the potential issue for the future and avoided it. Software is too squishy to expect it to always implement every standard perfectly. -mel > On Sep 26, 2025, at 7:57 AM, Nick Hilliard <nick(a)foobar.org> wrote: > > Mel Beckman wrote on 26/09/2025 15:32: >> From >> https://www.exam-labs.com/blog/configuring-lacp-between-cisco-ios-and-junip… >> *Understanding LACP Failures and Common Pitfalls* >> Link aggregation, although a robust feature, is susceptible to various issues.

If you have an LACP negotiation failure, typically the LAG interface won't come up to start with on a juniper / cisco device.

U.S. Secret Service shuts down NYC cellular disruption network
by Mel Beckman 24 Sep '25

24 Sep '25

The U.S. Secret Service announced today that it dismantled a network of electronic devices located throughout the New York tristate area that were used to conduct multiple telecommunications-related threats directed towards senior U.S. government officials, which represented an imminent threat to the agency’s protective operations. The SS say they discovered more than 300 co-located SIM servers and 100,000 SIM cards across multiple sites, and while the photo they provide shows gear set up in what looks like an apartment, it could be that interlopers have infiltrated actual Internet colo facilities. As a colo operator, I’ve turned away more than a few sketchy potential customers due to their flakey stories requesting rooftop or window antenna locations. Be on the lookout. https://www.secretservice.gov/newsroom/releases/2025/09/us-secret-service-d….<https://www.secretservice.gov/newsroom/releases/2025/09/us-secret-service-d….> -mel beckman

2025 State of Network Automation Survey - Requesting Your Participation
by Chris Grundemann 23 Sep '25

23 Sep '25

Hey all! It's that time of year again... Survey time. The 2025 State of Network Automation Survey is open!!! No automation experience required - please share with everyone who has edit access on a production network, regardless of how automated that network might be. https://www.surveymonkey.com/r/StateOfNetworkAutomation_2025 For consistency, and ability to track trends, most of the questions are word-for-word repeats from prior years surveys. This year I deleted a few questions that don't seem relevant anymore, and I made a few questions optional, rather than required, in hopes of MANY more responses -- I also built in some logic, so that *folks who have ZERO network automation experience / deployment can still answer the survey easily*, in hopes of more accurate data collection. There are also some new questions, all suggested by the Network Automation Forum community. Finally, you will notice that we (now with NAF backing) moved off of the free Google form to a much sleeker SurveyMonkey survey. w00t Again - we invite anyone and everyone with enable on a production network to complete the survey, and we hope that everyone here will share the survey in other foraa as well - mailing lists, newsletters, social media, discord, slack, reddit, etc, etc. Survey results have been submitted as a talk for NANOG 95 in October. And will be available publically one way or another before the end of the year. Thanks! ~Chris

Hawaiian Telecom contact
by nanog＠fleish.org 23 Sep '25

23 Sep '25

Hi all, If there is anyone from Hawaiian Telecom here that could ping me off-list about a service issue I’ve been fighting for a week now and am getting no where slowly I’d greatly appreciate it. Or if anyone has a good technical contact there who might not be on the list and wouldn’t mind reaching out to see if they would be willing to contact me that would also be deluxe. Here is a quick accounting of what has been going on in case anyone else it rings a bell for anyone and/or anyone else is experiencing it: I observed multiple Fioptics services across Oahu bounce multiple times last week overnight Monday into Tuesday. First thing Tuesday morning I started getting complaints of some user’s internet service not working. I tracked it down to users being NAT’ing out one of the “secondary” public/static IP addresses. If I moved one of those secondary addresses to another physical device with a unique MAC address then the IP worked fine from there. The HTEL Tier 1 call center had little more to offer other than power cycling the ONT, which of course didn’t fix it. They also mentioned it was not possible to have multiple public IP addresses bound to the same MAC address and had no response when I asked how it was we’d been operating like this for over 2 years? So they escalated to tier 2 who was supposed to get back to me but never did, so I had to call back in and request Tier 1 get me to Tier 2 again and they told me someone would call me back and it would take 2 hours. 4 hours later, Tier 2 finally calls back and says they cleared the ARP table on their side and I should try again, but also kept repeating the party line that a many to 1 IP to MAC configuration is not possible. I requested another escalation and was told there is none and my only recourse now was to have them dispatch a tech. So the tech came today and from what I’m told from the onsite folks they sent an installer who spent 2 hours on a chat with “the NOC” which is also not on island anymore they said. They offered no resolution and no escalation and told us we’d have to call back in to update the ticket to say that we’d tried his troubleshooting. Thanks, Todd

Comcast off-list contact for hierarchy screw-up?
by Aaron C. de Bruyn 22 Sep '25

22 Sep '25

Sorry for the noise, but I'm hoping someone a bit higher up at Comcast can help with billing administrivia as the techs I'm talking to have been useless. I have a ton of cable connections that are about to get axed due to bureaucracy. The short story in bullet points: * Large client owned ~35 offices went bankrupt, individual offices were sold off ~6 months ago * Change of Ownership files for all the accounts, thought everything was good * One account down this morning, after hours on the phone found out it's apparently still attached to the bankrupt hierarchy * Customers have been getting $0 due bills thinking it was on auto-pay * After getting the down office restored, got messages in my inbox to return equipment for other offices * Called in, gave tons of account numbers to an annoyed rep who said she would remove all the accounts from the hierarchy and bills would go to each individual office, but that most of them were "disconnected" already * Eh? All offices are online right now and I can connect to them. * "Sometimes it can take a few days for the accounts to get shutdown" * But I don't want them to shutdown... * Rep creates tickets for each one to fix things, tickets get automatically closed ~30 minutes later because the accounts are out-of-contract and the service plans are no longer available * Literal text: "I am writing to you today because we received the ticket regarding the account ending in (0000). After researching the account, we were unable to restart the account due to the package speed is expired.. You will need to have a current speed tier applied and that will need to go through our sales team at 1-800-391-300" * You're missing a digit in the phone number in your automated email * Accounts are still "disconnected" but online. * Customers don't want new contracts Thanks, -A
