Cisco Prime - Using to Audit Switch Ports and VLAN Associations

Hi folks

I'm hoping this is a quick question. I've to audit the available switch ports around the office to see if we need additional equipment (there's probably plenty patched not in use) and document VLAN associations etc...

I'm using Prime 3.1 which to be honest so far seems a little clunky. I'm looking for a way to easily grab which ports are assigned to what VLANs - I'm not to bothered about per switch if I can get it on that level. I can get the info but I have to click into each switch port which is a time killer ( I have 20+ 48 port switches to to go through).

Show VLAN ID is pretty much the info I want but don't have access to switch CLI's - just prime.

Anyone got any tips ? Also for you net engineers that had to do this task, what info did you gather or what was your approach (No harm in using this opportunity for advice!)

​

Cheers in advance.

Live Streaming Cache Solution?

I'm trying to watch a live stream on a very specific domain (https://very.specific-domain.com:1234/playlist.m8u3), however I'm on a very bad connection (this is the real issue... the stream itself got plenty of bandwidth to stream 720p content) and the video stream looks terrible or keeps buffering all the time.

​

I was thinking: is there a way to build a local cache server for this specific stream and buffer (let's say) 5 minutes of stream?

Any suggestions on how to achieve this?

Help with what protocol/software to use to pass a stock exchange UDP Multicast stream from data center to the AWS instance?

I have a data center which is a consumer of stock exchange connectionless multicast feed. I want to forward that feed to an AWS instance.

• What would be the best/ideal way to forward the feed to the AWS instance?
• What protocols/software can I use to forward or pass the feed to the AWS instance?
• How to make sure that the stream connects again and still forwards it to AWS instance in any case of connection or server downtimes?

Moronic Monday!

It's Monday, you've not yet had coffee and the week ahead is gonna suck. Lets open the floor for a weekly Stupid Questions Thread, so we can all ask those questions we're too embarassed to ask!

Post your question - stupid or otherwise - here to get an answer. Anyone can post a question and the community as a whole is invited and encouraged to provide an answer. Serious answers are not expected.

BSO Low latency fibre

We have a fibre link between UK and Asia, provided by BSO.

There's been an outage on it since Monday due to a "backbone fibre break" - that's the official word from BSO. What kind of service have we signed up for when they can't re-route us another way?

These circuits were signed and paid for by a person no longer employed, and the company who took them on merged with us last year, that's why I'm now supporting them with little knowledge of what they actually are.

Surely in the background it's just some kind of vpls implementation, but engineered for low latency, or is there some other technology in place here?

A map of the Internet

Hi r/networking,

I've recently been intrigued by visualizations of the internet that I've come across. Examples include The Opte Project and The Internet Map. How would you go about beginning a process like this?

Making an SD-WAN decision - When to use an MPLS with a DIA circuit as opposed to 2 x DIA circuits

Hi All

I would appreciate the communities thoughts on SD-WAN in relation to a recent chat I had. A customer who was looking at SD-WAN were most excited about the possibility of moving away from there MPLS network which could potentially give them more flexibility of circuit choice, and a possible cost savings by replacing there MPLS, in addition to some of the other benefits.

During the chat, I mentioned that SD-WAN is transport agnostic in that you can connect whatever circuit you want to it, whether that be an MPLS link or DIA. The customers made the statement ‘I would love to be able to go to the board and propose this solution and the risk needle to stay the same’. In this scenario, the customer wanted to move completely away from an MPLS network to having 2 DIA circuits at the site only.

This question in relation to the risk needle movement has occupied my thoughts for a few days as there are a few variables at play here and has driven me to find a more objective response and structured framework I can use to give a more honest, clearer response in future.

My response was that customers who want to guarantee that same level of performance or are perhaps more cautious often choose to have a hybrid setup with one link being MPLS and the other being a DIA. They can have peace of mind that the business critical performance traffic is sent on the MPLS, SLA backed circuit. With the flexibility to send non-critical traffic over the DIA.

The real heart of the question I am trying to answer is around when should a company choose a hybrid SD-WAN deployment and when can you move to an SD-WAN deployment with 2 x DIA circuits.

I appreciate that answering this question is specific to each and every customer. However, there is a grey area between the two solutions in my mind as to how and when you should choose one over the other. It would be interesting to hear how decision-makers have come to a conclusion and to understand their motivations. Not all organizations have the luxury of being able to compare the two solutions side by side before making a decision.

One argument I have heard is that you can get DIA circuits that perform at a level close to that of an MPLS link. If you have 2 x DIA that experience on average 1% loss then combined it would give you 99.99% uptime, which is a similar kind of guarantee on some MPLS links. As outlined in the article below

• https://www.sd-wan-experts.com/blog/calculate-network-availability-multiple-wan-circuits/

The two DIA circuits in combination with SD-WAN dynamically moving traffic between the best tunnels, and on top of that, the option to use packet duplication or FEC to me seems quite a solid offering. Where is the risk here that I might be missing?

Nortel 2526t POE not working - - ideas?

I just picked up an old 10/100 Nortel for $20 for my home camera system, but the POE is giving me issues.

I finally managed to get it connected with telnet (the serial adapter I bought isn't working for direct access), but the "no poe-shutdown" command is not working.

Here's what I do after connecting to telnet:

enable

config terminal

interface fastethernet 1-12

no poe-shutdown

ctrl+z

exit

Am I missing something? I don't get any POE. In an attempt to troubleshoot, I used a working POE switch and went:

[Test Camera] > {Working POE Switch} > {Nortel 2526t Port 6 (POE)}

And with that, I was able to get the camera working. So that determines the ports work, but POE isn't enabled.

Ideally, I'd just hard reset the switch, but (apparently) that's only possible with a direct COM port connection and I'm not able to get the DB9 to ethernet cable working (even with a crossover cable).

Any ideas?

DSLAM book

are there any book/books that explain how to configure a DSLAM, difference between atm and ip dslam like MSAN?

Affordable solution to manage small computer lab in classroom

Hi Guys, I have a small lab with 20 computers with Windows 10 on them. I need to set up an environment where I could manage centrally all computers in room. My requirements are:

• domain management, each user has his account
• management of software installed on users accounts
• each user has 200MB space for his personal files
• personal files needs to be accessible from outside (maybe NAS server ??)
• "teacher" computer needs to have control over other PCs

Is there any other reddit to ask this question? Could you tell me some ideas how to start setting up this environment? Thank you guys! Sorry for my English.
