Hi,
we now have a linkrunner(old) and a aircheck G2, and we are looking to uprade to a 10g tool.
I am unsure of the exact difference between having a linkrunner 10g and a aircheck, or having a etherscope nxg. The website doesnt really give much info, and I tried the live chat but the rep wasnt helpful, didnt seem to know.
Has anyone tried both ?
Does anyone have experience, or recommandations ?
Any hints ?
My enterprise hosts a few externally reachable services, but not very many of them. Currently we have a provider assigned /29 on our circuit, and publish dns records for them.
The problem is our carrier is a single point of failure. We want to bring in a second carrier in the interest of redundancy and failover.
But the standard way of doing this seems to be to acquire our own ASN, and our own block of public IP space, and that we need a /23 minimum. (The reason I say /23 is so we could advertise a specific /24 to one carrier and the whole /23 to the other for clean failover.)
We only host a small handful of services, so a /29 is just right for us, a /23 is massive overkill. Even a /24 is massive overkill.
It also sounds incredibly burdensome for an org our size to maintain all the records with Arin of having our own ASN, and own IP space, etc.
Is there any service or method out there for accomplishing carrier failover without needing to advertise carrier-independent nets out to multiple carriers? How do smaller orgs like ours handle this? Do they just accept the single point of failure and move on with life?
Hi Guys,
I work with three Cisco switch stacks which relate to 3 floors in our building. They are linked via IP port channels so each floor is essentially their own network.
I have created a Guest VLAN (240) on our new WiFi infrastructure. This Vlan interface has been created on the 3rd floor switch and then added on the other two. I want the guest VLAN to be available on all three floors as one network. I have therefore extended the Vlans across the three switches via trunks allowing the 240 vlan.
I have connected a AP on the 3rd floor switch and I have able to get a 240 IP from from our SonicWall and connect to the guest network. However when I connect a AP to the 1st floor and try to connect to the guest network I can not get an IP. I tried on my mobile device and it is stuck on obtaining IP.
Any ideas where I should be looking to try to resolve this? Thanks.
My understanding is that in order for this to happen, the host or router must encapsulate a layer 3 packet in a layer 2 packet with the MAC address of the layer 2 destination (correct me if am wrong).
Does that essentially mean that the overall layer 3 has been modified or changed when transmitted on ethernet?
I am trying properly understand this, but I keep coming across conflicting information so I figured I would ask on here.

Hey everyone,
I see a lot of discussions lately referencing OSS projects, and projects that are free as in beer, speech, or both. That's awesome, but I have a ton of questions
Who is using various OSS projects in prod in enterprise environments? Are you getting vendor/MSP support or self-supporting? How big is your org? How big is your team?
Are other IT practices within your org leveraging open source projects?
I'm not just curious about stuff that's in-band like Vyos or Quagga, of course I am curious about that too...that Vyos post just spawned my curiosity, after all. But what about out-of-path and supporting systems? I.e. I use Guacamole and Ntopng and Gitlab, but if these systems go down I'm not impacting users and I have other means of getting around.
Has anyone had any experience with this at all? I have a client with a completely botched Active Directory migration and I was planning on basically starting over from scratch with a new domain in a new vm.
However, doing some research I discovered Univention Corporate Server. This client has very simple requirements for their domain, basically user personal network storage and 3 different shared drives.
They could benefit from the cost savings and would philosophically agree with the open source nature of Univention. I am also personally a lot more familiar with Linux than windows server.
I just wondered if anyone else has even deployed it and whether anyone has had any success with it.
Will be using a service provider to aggregate multiple remote B end locations to one aggregation A end location, metro Ethernet style. Traffic from each B end will arrive at the A end with a different outer TAG. Does anyone know what Cisco router or any other brand router that will support this.
Hello there,
is there anybody who is working with Auvitran Audio Toolbox? I have the 3 slot configuration -> Slot1: Dante, Slot2: AVB, Slot3: ADSP.
Dante is working fine, but somehow i have issues on getting the AVB card working. I did the Matrix routing from Dante to AVB. The AVB Outputs have Signal, but how do i route it into the avb network or how do i get AVB traffic from the network?
I did notice that there is no AVB link from that card. What could it be? Card defect or am i forgetting something important?
I'm struggling to understand and choose what design is better. So there is an ISIS FRR enabled in the core and it's same switchover speed as MPLS FRR (~25-30ms). But LFA doens't cover everything due to topology. So we using TE tunnels in hot-standby (path protection) at key points where LFA doesn't work.
I've done tests to measure switchover time, so all of them have a switchover time <50ms.
So what's better? Using link-node protection (MPLS auto-frr), which creates a lot of auto-tunnels and makes troubleshooting a little bit harsh.
Or using path-protection with bfd (hot-standby), which also doubles the number of TE tunnels and requires bfd with aggressive timers?
I've read a lot of documentation and some vendors reccomended to use those both options.
Can someone share their experience with core FRR design? Maybe i'm just overthinking it, but i want to find proper solution.
