We are currently dealing with an issue between two Dell N3000 series. We have a mix of N3024 and N3048 units in our office.

The issue:

We have two buildings connected via 10GbE SFP.

In building A the ram log is constantly reporting the connection failing.

In building B the ram log never reports a connection loss (I would have thought it should?).

Initially the connection was often coming back up after about 5 mins on its own but is now staying down until 1 or sometimes both units are power cycled.

I am wondering if this is normal or if perhaps we are having a hardware issue?

Hello, I'm new in networking and have been tasked with setting up our network with VLANS. We have two Powerconect 6248 switches configured in a stack. We created two VLANS (10, 168) and assigned ip address to both and enalbled routing. We have also enabled ip routing feature of this switch. We can ping within the vlans (vlan10 device to vlan10 device and vlan168 device to vlan168 device), but we cannot ping between vlans.(vlan10 device to vlan168 device). In addition, we can reach (ping) the Internet from a device on vlan10 but we can NOT reach the Internet from a device on vlan168.

MGMT VLAN = VLAN1 (default)......10.1.1.1/24 (connected to firewall X0 port)

VLAN10......10.1.10.1 /24 gw 10.1.10.254 (connected to firewall X3 port)

VLAN168......192.168.168.1 /24 (NOT connected to firewall)

Here is my running config, and thank you in advance.

We feel as if we are missing some routing commands but we are unsure. It was our understanding that with the configuration listed that we should be able to ping between devices on either vlan (from vlan10 to vlan168 and from vlan168 to vlan10) but that is not working.

Thank you for your assistance.

Hi There,

I have a PowerConnect 2824 switch and I would like to access its management. Knowing that there's no way to change VLAN1 or its management to another VLAN, how can I access it without having change port?

Because, currently I have kept a port with VLAN1 as the PVID since I couldn't login if do any changes..

Hi All,

We've have acquired 2 x Dell N3024 switches for our business. We currently have one stacking cable to interconnect the two switches. This seems to work e.g. shows up switch 2 in the OpenManage GUI.

However, all documentation and videos from Dell demonstrate installing two stacking cables into each port on both switches. Sources here:

(Please visit the site to view this video)
www.dell.com/.../HOW10356

I was under the assumption that the other spare port is for stacking more switches together.

Can this be confirmed?

Thanks,
Jake

switch is an N4032. how do you change the mtu on a port? tried menu-on-left/switching/ports/port configuration and it shows "maximum frame size" as 1518, but thats not a changeable value. anywhere else, ive only see instructions indicating that this can be changed, but not how.

found instructions for doing it from command line, but cant ssh in (see my other post)

I am in search of help concerning needed entires to get ssh to work on a Dell Powerconnect 6248p. I have read through many postings for what entries get ssh to work, I have entered all of the entries, and when I utilize putty or tera term the connection times out. Here is my config, and below it I will list the entries applied. Any help would be greatly appreciated.

We've just configured a 2048P Dell Switch in our infrastructure.

We were having some problems with our switch cores, so we decided to add a extra switch to divide the network load.

We've configured the trunks to our cores and added the connection to our internet circuit (all the outside traffic will pass trough him).

In the logs we checked that we're receiving the following errors from our Wireless Controller.

How can we solve this?

Hi all

I have some N3024P switches that need to be set up.

There is a requirement to automatically place VOIP phones that are connected to the switch into the voice VLAN automatically.

Is this possible with these switches? I have been looking at GVRP in the CLI but it's not clear to me how it can help with this.

What I would imagine is somewhere that I can enter a MAC OUI, e.g. a specific manufacturer, and then state what VLAN to place that MAC within.

Thanks for the assistance

Let's imagine this scenario - simplified from our desired set-up

VLAN 1 - server vlan 192.168.1.0/24 

VLAN 2 - client vlan 192.168.2.0/24

VLAN 50 - guest wifi vlan 192.168.50.0/24 

We want to route freely between VLAN 1 and VLAN 2 but prevent any traffic routing to/from VLAN50

I have read and understand this Dell VLAN routing guide  but this only covers the scenario when you are happy for everything to flow between all VLANs.

I have a few questions which it would be great to have some help with

1) Global routing - we think that if we just do

ip routing

this will route between all VLANs which is not what we want - correct?

2) However, if there is no IP address set on the VLAN 50 interface, it won't route, correct? So as long as no VLAN which we want to isolate has an IP address assigned in that VLAN, no routing? 

So we could then issue an "ip routing" command, and we would get what we want, providing we never configure an IP address on VLAN 50 interface. Let's call this "Solution A"  - does it work?

3) Static routing - if we issue static routes to particular subnets this will allow all VLANs with IP addresses set on the interface to route to them

e.g. if I do 

ip route 192.168.1.0 255.255.255.0 192.168.1.1

then VLAN 2 can get to VLAN 1, but so can VLAN 50

Is that right?

4) However, if I never create a route back to VLAN 50, then although traffic could route from VLAN 50 to VLAN 1, replies could never come back again - right?

Let's call this solution B - does it work?

5) If we wanted to issue static routes which only applied in certain VLANs it looks as though DNOS has an vlan parameter to the ip route command - but I can't find any explanations of exactly what that means or how it works?

Let's call this solution C - would that work?

6) Lastly, assuming all these solutions work, which is the best solution?

Thanks.

Hello everyone :)

I'm trying to run hardware test on DELL switch n2048 by CLI and WEB, but i can't find option like this.
Search in google without result. Have the last firmware. Have a problem with this switch but can't understand it is configuration or hardware

Please help me.
Thank a lot.

Does anyone know the N-Series (specifically the N2048) requirements/restrictions for the RADIUS shared key?

I couldn't get it to work with the same shared key I used in previous generation switches (5424).

Either it doesn't support special characters such as !&%^ or the length limit is smaller than before.  I finally got it working with a 32 character key with no special characters. I couldn't find any documented limits.

Hello,

I am trying to setup the trunk port between two N4032 switch. the purpose is to implement the vrrp with these two switches.

may I know the trunk port configuration and best practice for vrrp.

Thanks.

Dears,

please how to make high availability on San Switches located between the storage and servers

if i have two switches N4000 Series what is the possible ways for high availability ??

Hi,

I have a stack of 7048 switches. Currently every thing is on Vlan 1 and I'm trying to separate the things into couple vlans.  So, I created vlan 10 and give it an ip address. I also gave Vlan 1 an ip address for now. I assigned two ports to access vlan 10. Now PCs on vlan 10 can ping each other. However, it can't ping vlan 1. I'm assuming that it's switch L3 and should be able to route between Vlans once enabling ip routing in globle config. When I do show Ip route, I can only see vlan1 as directly connected. It's not showing vlan10 as directly connected. Also I'm unable to ping vlan 10 ip address from vlan 10 hosts. Any ideas ?

Thanks

Hey,

This is my first Dell switch set up and it's not going so well :). I'm used to configure Cisco switches which shouldn't be a big difference as I think ?

Any way here is what I'm trying to do:

Our network is messed up and I'm trying to organize it. All the company is on Vlan 1 and I want to separate the network into multiple vlans. 

I started to create a simple Vlan 10 with ip address 172.16.10.1 255.255.254.0 for the users and assigned  port 30 on the first switch (We have 3 stacked switches) and plugged in a laptop to see if I can get to ping the vlan 10 but no luck (of course I put a static ip with the same range of the vlan 10 network). When I put a static ip on the laptop with vlan 1 network, I can get access to the network. Any ideas of what I'm doing wrong ?

Here is the port configuration:

Access Mode VLAN: 10
General Mode PVID: 1 (default)
General Mode Ingress Filtering: Enabled
General Mode Acceptable Frame Type: Admit All
General Mode Dynamically Added VLANs:
General Mode Untagged VLANs: 1

Hi all,

I've 3 swtichs on stack. And I have one device, when I connected on any port, device do not communication. Led not flashes.

Device is OK, when I connect on my NB, communication is OK.

Thank you for you reply, and I am sorry, my English is so bad.

Hello,
    New to the world of networking and was looking for some assistance regarding 2 Dell Powerconnect 6248P switch

that I recently purchased. They are currently stacked with a 10GE CX4 stacking module and all of that appears to

be in order.  My network topology is extremely simple with a home router that is able to do static routing

connected upstream to DSL and downstream to port one of the first switch (management switch - 1/g1). The router IP

address is 192.168.1.1, and it is also the DHCP server.  I have set up DHCP reservation for the switch with an IP

address of 192.168.1.254.
In the router I have set up 3 separate static routes:

10.10.10.0     255.255.255.0     192.168.1.254
192.168.3.0    255.255.255.0     192.168.1.254

I am trying to set up 3 different vlans:

VLAN 1 - Internet     
VLAN 3 - Management     
VLAN 100 - internal lan for severs

Please note that I have scoured the message boards and been though at least 15 different iterations without any

success.  Here is the my configuration file - it is small because I have just recently reformatted the file system

and restarted from scratch.  Also, both switches are at the latest firmware.

2) The GUI can only be accessed by 192.168.1.254, not 192.168.3.1 as I had intended (management VLAN). Moreover, it still lists vlan 1 as default. I cannot rename vlan 1.

3) I have a windows PC connected to 1/g6 (registered to VLAN 1). It can ping the internet but cannot ping 192.168.3.1, nor can it ping 10.10.10.1

4) The switch can ping pboth VLAN 3 and VLAN 100 Interface

I have been working on this for nearly a month and finally decided to do my own post after scouring many of the other posts on the support forums. Any help would be greatly appreciated. I know it is an old product but I still have a warranty on them.

Sincerely,

Prashant
