Unifi Aggregation

[Simcfc73]

Hi,

 

I've read that the auto negotiate is a little temperamental on the Aggregation switches. I've managed to set a couple as 10Gb by forcing it but I've just tried another one and its killed my network and I can't see most of the switches... they must be working as I can see devices on the LAN.

 

I should have put a redundancy link in when I started so this didn't happen.

 

Anyone had the same issue?

[ZeroHour]

I thought they can be a sensitive to SFP used with some not working properly at all, are they different SFP modules?

[Simcfc73]

I've bought all Unifi ones.

 

I've had a major disaster this morning and had to reset loads of switches to get people on. I've linked a couple of switches with copper too as the agg switch didn't link them.

Ah, good to know - we're looking at upgrading our switching this summer, currently planning on Ubiquiti core and edge switches, this is something we need to look into in further detail first.

Its a start and unbelievably more speedy than last week.. no ones in though.

 

I can't get the long distance ones to work. I bought these UACC-OM-MM-10G-D-2 but its syaing loss of signal when I connect.. The standard 1G ones work ok.

Just to note the 1g are rated for 550m and the 10g are 300m.

 

Are you sure your runs are not more than 300m?

Have you checked that the cabling and SFP modules are compatible?

I have two buildings connected via two US-16-XG switches, with ports 1-4 aggregated to give a 40Gb connection. I'm using UF-MM-10G modules. If I recall correctly, I set each one up individually and manually set to 10Gb first before aggregating.

The other switches in the same cabinets are all connected using unifi UDC direct attach copper cables and are at 10Gb. I have these all set to manual and 10Gb. I didn't experience any loss of connectivity.

 

I'm sorry this isn't much help to you, but at least you know it is possible.

[gaz350b]

Also when you aggregate them you have to do consecutive ports so ports 1 and 2 NOT 1 and 3.

 

(Edit: Just realised there is no aggregation going on).

Yes this was my thinking - What's the quality of the fibre (OM1/2/3/4) & how long are the routes? They may be longer than realised.

[Simcfc73]

Less than 200m. Was installed more than 20 years ago before I started.

 

24 core but I've not found any writing on it. I'm using OM2 tails.

[DrCheese]

What colour is it? Not an exact science but you can usually work it out from that

OM2 you can run 10gb at a max of 82 meters

Its possible its OM1 or older with a larger core diameter than OM2. You will get loss of signal if you don't match the core diameter.

 

If the side of the cable isn't labeled, then it is unlikely to even meet OM1 standards.

 

OM1 is 62.5/125 micron

OM2+ is 50/125 micron

[Simcfc73]

Its black so doesn't follow any standards.

 

Looks like I might just be using aggregating for the link.

 

I've got a shorter link I might try tomorrow and see if that does it.. I know thats only OM2 as I had it installed.

 

The longer building link runs under a driveway in a conduit and has a pull cord still in to so might look at upgrading sometime in the future.

[Simcfc73]

I've found some text on the cable but I imagine its not even OM1.

Took me a while to find it in various catalogues available online but it's OM1.

 

A site called yumpu.com has it listed in one of their catalogues as 24-core multimode OM1 fibre.

I'd assume 062 is 62.5/125 aka OM1, with 24 being the core fibres - That's how a number of them phrase it

Ta, looks like I need to upgrade it to get any speed.

If you do - get Single Mode OS2 for these reasons:
