Cisco 2960 - need help to set up

Claus posted:

Hi,

Having read several positive posts about the Cisco 2960 Catalyst and seeing one for sale (s/h) I decided to give it a go. 

Until now my configuration was Netgear Readynas and ND5SX both ethernet wired into router. Everything working fine. 

Some time ago I also tried inserting a switch GS105, as a connection point btw NAS, player and router. I never got it to work - however as the NAS and router conveniently are located next to eachother and the ND5SX 5-6 m from there, for practical reasons it worked fine without the switch. 

So in with the CIsco, cable from router to switch, in port 1, cable from switch to ND5SX in port 2 and the 3rd cable from switch to NAS in port 3. Problems is that I can't connect to the NAS via wifi (from FIlemanager in win10 pc) and the player can't see the NAS via the cable either. 

Just tried swapping the Cisco with the GS 105, and the result is exactly the same. 

What have I done wrong? I can find the Cisco management window from the PC, 

May be worth to mention, that I have the NAS set up with a static IP address, to make it easier to access the management "console" from the pc. During the cisco express setup which I ran after resetting the switch I have assigned a static IP address to the Cisco as well. The netgear GS105 was simply plugged in. 

I could of course go back to a network setup without a switch, but I really would like it to work this way also, hoping to get some SQ benefits and for practical reasons in case I decide to put NAS and ND5SX close to eachother some time later. 

Hope there is an easy fix to this. I guess the problem isn't with the Cisco as such, since the GS105 gives the same problem.

i had once the same problem.  Try to restart your nas first then your nd5x.  It should work.  

If not, ask Simon in the suffolk.  good luck.     If your cisco was factory reset, you have nothing to configure.

I would start by setting everything to use DHCP with no static addresses, then do a full restart of all devices on your network, starting with the router. 

Thanks, will make a restart of all units, if that doesn’t help then remove static iPad addresses. I would prefer though to have a static address for the nas at least.

If that doesn't work, you can reset to factory default by pressing and holding the button on the left. Here's an overly dramatic video of it.

Thanks, did the reset first thing already. 

Forgot to mention I first post, that nd5sx is happily playing iradio controlled by my iPad. Only nas is -completely- out of the loop. 

Will try power off and on when back from office.

A silly question from me - Do all static IPs share the same first 3 octets, e.g. 192.168.0 or 10.0.0 ?

If they do, make sure the last 4th octet of the NAS's IP is not too big, some routers do not like the number bigger than 63, some are OK with 253.

Please set your NAS to use DHCP.. to get its IP address... and then report back... that is what DHCP is there for..  then it might all start working.

without that you need to do manually, and unless you know what you are doing, the chances are it won’t work.

No it depends on the private network class and subnet mask , a class C network always starts with 192.168.x.y and has upto 254 hosts per subnet. a class A network always starts 10.x.y.z and can have upto 16777214 hosts. The subnet mask splits this space up. A class c network has a default mask of 255.255.255.0, which means there 254 maximum host addresses, and in which case the first three octet describe the network address... a class c network of 255.255.255.128 means that 192.168.x.0 and 192.168.x.128 are two different subnets of 126 host per subnet, here the first three octets and half of the fourth octet describes the network address.

A class a network can also have its subnet subdivided by its subnet mask. So a class a network of 10.x.y.z with subnet mask of 255.255.0.0 will have 65534 possible host addresses, and here 10.x.0.0 becomes the network address, that is the first two octets , .. so you can see the subnet mask becomes essential in describing a network address.

Thanks Simon for the detailed explanation, however in a typical home network, you usually have the addresses 192.168.0.x or 10.0.0.x with a subnet mask 255.255.255.0

In a typical home network with consumer router, one has a class c network, starting 192.168. And a subnet mask of 255.255.255.0.... so the last octet defines the host IP address of upto 254 hosts, and the first three octets define the subnet address like 192.168.1

Class B (172.16.x.y) and class A (10.x.y.z) networks only usually  make sense for home  networks if they have subnet masks of 255.255.255.0 or smaller... that is subnets of 254 hosts or less, but there is nothing technically stopping you from having larger if your home router can support.

Hi again

Feeling a little embarrassed I am happy to inform that a simple power cycle did the trick! Why didn't I try that before asking for advice ...., 

Simon, the Nas is set at dhcp fixed 10.0.0.61, before I did that it sometimes changed which was inconvenient if I wanted to log in to the nas' front view administration. 

Perhaps too soon to celebrate, as I haven't yet tried to  connect to nas from pc. But music is once again streamed with the Naim app

Once your NAS set up at 10.0.0.61 by DHCP, it will stay at this value (unless you refresh the network config), no need to assign a static IP for Web viewing / control.

Ok, but what does it take to change? A reboot of the router? I ask because when starting using the nas it changed address one day and it took me some time to find the new 10.0.0.?? Number needed for accessing the admin software of the nas. Since then I have used a fixed dhcp address. 

Usually a router reboot can change the DHCP addresses theoretically, but in my experience, they are still the same as before the reboot.

Btw, not sure about your NAS, my NAS Is QNAP and I always access it by name instead of by IP, and there is a Qnap Pro finder which helps me to locate the right NAS.

I think there is similar for the Netgear, however my pc is from my job and I can't install extra software on it. My wife's pc is used when I really must do that, as when updating firmware on Naim equipment. With a known dchp I can also easily log in to the admin page from my iPad or phone. 

Is there any iOS app that allows you to access / control your NAS from the cloud regardless where you are geographically?

I can access my QNAP anywhere I am without knowing the its specific IP. 

There is supposed to be remote access, but I'm not using that because my upload speed is very slow.

I don't think there is an app to access the NAS in "control mode", this is done by a browser on the wifi (any browser will do). 

Oh yeah, when connected via the switch, the IP address of the NAS has changed to 10.0.0.4. Even if it was set to fixed at 10.0.0.61 in the control panel. I have now disables fixed IP address.
