1G/10G BaseT switch recommendation
by Drew Weaver 26 Jul '21

26 Jul '21

Hello everyone, I'm looking for recommendations from the community on 48x10G RJ45/4-6 SFP28 (uplink ports) switches that people actually like working with. Features are VPC or non-vendor specific equivalent, L2/L3 BGP/OSPFv3, ACLs, functional CoPP and some sort of API to manage them. [the CLI would work, my lib can handle most Networking OS CLIs anyway] My problem point is coming from the RJ45 requirement, most vendors have one switch that they sell that is RJ45 at 10G or at the most one in each line (enterprise/datacenter) and they seem to be almost an afterthought. [probably because SFP28 is better in every way if you are already using fiber at the endpoint] sadly, we are not. I just want to make sure I am not excluding any vendors from my research. I appreciate any suggestions or recommendations. Can even keep it off-list if you want. Thanks, -Drew

Spamhaus ASN-DROP list
by Siyuan Miao 23 Jul '21

23 Jul '21

Hi All, One of our ASNs has been listed in the Spamhaus ASN-DROP list before it was assigned to us. We emailed them last year but didn't get a response. Could anyone from Spamhaus contact us off the list? Best Regards, Siyuan

Is Verizon core network broken? Can someone reach out to Verizon core network team so that they can look into why so many networks are missing?
by S Umple 23 Jul '21

23 Jul '21

Hi, I've been a new Verizon residential FIOS user since May and the mysterious connectivity issues at home lead me to a bit of hunting. From what I can tell, the Verizon network as a whole effectively blocks or filters following major networks. The same networks are mostly reachable from AT&T LTE networks and major cloud computing providers. Below is a comparison of 'show ip route' of a VZ router and a routeviews router. <VZ INET router># 81.0.0.0/8 is variably subnetted, 2835 subnets, 14 masks 121.51.0.0/16 <empty> 182.254.0.0/16 is variably subnetted, 3 subnets, 2 masks route-views.routeviews.org> 81.0.0.0/8 is variably subnetted, 3247 subnets, 19 masks 121.0.0.0/8 is variably subnetted, 2571 subnets, 18 masks 182.254.0.0/16 is variably subnetted, 113 subnets, 5 masks Anyone able to validate my findings, and/or take this issue to higher VZ support? Thanks.

100G, input errors and/or transceiver issues
by Graham Johnston 19 Jul '21

19 Jul '21

Good day, Over the last two years, organizations that I've worked with have upgraded equipment and now make regular use of 100G port speeds. To provide a frame of reference on use cases, the organizations that I've worked for make use of 100G speeds within their own data centers, in carrier neutral data centers, and lease 100G transport from larger carriers; they don't currently operate their own 100G coherent/long-haul networks. - How commonly do other operators experience input errors with 100G interfaces? - How often do you find that you have to change a transceiver out? Either for errors or another reason. - Do we collectively expect this to improve as 100G becomes more common and production volumes increase in the future? Thanks, Graham
