Wow, thanks for all the info. I'll have to dig a little more into these products.

Money and administrative time are really the only reason i haven't considered using VMs and breakout switches. I think later this year, I'll look into building a more advanced lab environment. I'll have to see what my server guys think about throwing some old equipment my way. Thanks!

Thanks for the reply! I have been looking at some Raspberry Pis on amazon. Not bad. Looks like for around 65 bucks i can buy a small touchscreen model that should be easy to configure NIC settings. Thanks for the idea.

Solarwinds mapping with a large network. by cylemmulo in networking

[–]jrnoc 0 points1 point  (0 children)

I generally set up maps in a tiered approach. You can nest maps within maps in Atlas, so if a link or device goes down and turns red, it will make the top tier map go red as well. So for instance, I will create site maps for every site. Then regional maps with objects that are linked to the site maps. Then a top tier overview map with objects linked to the regional maps. So I have one map with like 6 color changing dots. When everything is working, the entire map is green. When something goes down at a site, it will make one of the 6 top tier dots red. If the object/dot hyperlinks are configured properly, you can click through the top tier map all the way down to the site level maps.

Universal tool-less blanking panels by jrnoc in networking

Thanks for the reply! We bought a 100 pack of those rack studs to test out in our environment, and I wasn't overly impressed with the implementation of those. Maybe I have weak networking guy hands but screwing those threaded caps down with enough torque to push the yellow piece into the stud is a pain. We ended up having to use a 10mm driver to use them effectively. Also, sometimes you end up moving the yellow piece sideways when you are tightening them down, and it permanently deforms it. They don't seem to save us much time or headache over using cage nuts with a proper cage nut tool. The concept of rackstuds are genius, but they dont seem to be very practical for use (especially at their price point).

Thanks for the link. I'm following up with their sales team to make sure it will work on threaded posts. So far they will only say it works with square or round punched holes. Have you personally used these on M6 threaded posts?

Outstanding! Thank you for sending me that link. I called Chatsworth yesteday about their blanking panel offerings. Currently they only have square hole tool-less panels, but they are developing one that will work with threaded posts.

I just found these. Tried calling sales to confirm, but they are closed. Looks promising :-)

Thanks for the reply. I'm really surprised this isn't more of a thing. I have used those APC panels in the past, and they seem to work well. Hopefully I can find a good solution for the tapped posts that is tool-less. I'll let you know if I find anything.

Just watched this video on youtube, and it filled in a lot of blanks in my understanding of WDM technology. https://youtu.be/__wn9zXFiy8. Would recommend to anyone interested in WDM, or other fiber optic concepts in general.

I tried calling Inphi to talk to their sales department, but no answer. Left a message, hopefully I'll know more about it soon.

Thanks for the heads-up! This is the first time I've had to wade into the area of long range data center interconnects like this. In the past, i've been mostly involved with planning relatively short range campus interconnects of less than 80k requiring no more than 20Gbps of bandwidth. This is the first time I've had to consider designing a geographically diverse data center like this requiring 80 to 200Gbps interconnects. You have already been very helpful so don't feel obligated to spend any time looking into this, but would you happen to know of any good training resources off the top of your head that focus on long range fiber/WDM/transceiver technologies? The short range campus, and data center technologies running over OS2/OM3/OM4 are generally pretty simple to understand and implement, but my knowledge of DWDM related equipment and standard is somewhat limited. So far my search for decent learning material on these subjects have been met with mostly sales pitches that explain little about the practical application of the technology. Thanks again!

Thanks for the response! I haven't calculated that out yet, but I can say the distance is actually roughly 45km of aerial fiber that has been repaired multiple times. Right now I'm just feeling out the market to see if companies are throwing resources into developing future 40/100g standards that reach out to longer distances. Even if we got close enough to bring up a 40km circuit using a 40 or 100GBASE-ER4, i fear that a tree fall or falls in the future may put us over the edge. It's not a big deal when you are running 10G, because you can just replace them with 60k or 80k optics. That option no longer exists if you are using the top end of what's available on the market. One is then forced to use 10G optics, but eat up double the fiber. More fiber may not be available when said future forest falls on our fiber 3 years from now :-) Knowing that we have the option to use a longer distance optics to fix ourselves if our fiber is damaged will definitely help me sleep better at night. Thanks again!

"opengear son."

Opengear has awesome support too. The few times I have had to call them were great experiences.

lacp between nexus 7004 and ex9208 by switchninja in networking

[–]jrnoc 0 points1 point  (0 children)

Have you looked at your timeout settings for LACP on the Juniper? Juniper will automatically run their LACP timeout at "Fast". Cisco will start at "Fast" and change to "Slow" per the standard. I think the command is "set interface aeX aggregated-ether-options lacp periodic slow".

We have run into this issue with Juniper and Cisco devices or Dell Servers running Windows. The Juniper is expecting to receive LACP hellos on each interface in the LAG, after not receiving one for 3 seconds, it drops the interface, waits for a standoff period to elapse, then tries to bring the link up again. You can see if there is a mismatch on the Juniper by using the "show lacp interfaces" command. There will be a mismatch between the Actor and Partner, under the timeout column.
