Dell N2048 Switch CLI setup help

[friendlytechnician]

Hi All,

Does anyone have experience in setting up a Dell N2000 series via the Command Line Interface?

 

I've got 8 identical switches and recently added a 9th to expand the network. The other 8 were installed by a company we no longer have contact with.

I've followed the instructions as far as I can go, but have hit a wall when it comes to getting the switch to communicate with our main core switch management system.

 

The original 8 switches have all been setup with the following VLAN configuration:

VLAN 1: IP address: 0.0.0.0 IP Mask: 0.0.0.0 Method: DHCP

VLAN 10: IP address: 10.10.1.1 Mask: 255.255.0.0 Method: Manual

 

It looks like the switch can be setup with a double VLAN mode. However, when I follow the Dell auto config wizard to set my new switch up, dual VLAN mode is not an option. All I can do is setup VLAN 1:

VLAN 1: IP address: 10.10.1.9 Mask 255.155.0.0 Method: Manual

 

I need to configure it to have the same double VLAN config as the other 8 switches above, with VLAN1 on DHCP and VLAN 10 on Manual, but the 2500 page CLI config manual is sapping me of a sense of humour.

 

Can anyone point me to some useful CLI commands I can use to setup this double VLAN mode? I can connect to the CLI via terminal no probs, I just need to figure out the correct commands. To get the VLAN's looking like this:

VLAN 1: IP address: 0.0.0.0 IP Mask: 0.0.0.0 Method: DHCP

VLAN 10: IP address: 10.10.1.9 Mask: 255.255.0.0 Method: Manual

 

Thanks in advance,

Kieron.

Are you working with a console cable? Rather than connecting to an IP address.

 

Off the top of my head

Config t to get into configuration mode

Vlan 10

Exit

Interface vlan 10

IP address 10.10.1.9 255.155.0.0

 

Basically if you've got the the configuration of a working switch and just want to duplicate it's settings you should be able to do "config t" then copy the original switches configuration line by line to replicate it. Changing any ip addresses and vlan tagging as necessary.

Don't forget to save the config.

 

It looks like it will be the same a Cisco. So it will be wither WR or COPY R S

Thanks both, I made progress.

Yes, I'm connected via putty through the serial port. I need to set this command up before I can get web access to the switch it seems.

 

I configured Vlan 10 as ghanel suggested, this worked, and I did need to save it - for Dell this turned out to be the command "do write" I am now left with the following vlan IP interface:

 

Vlan 1 UP 0.0.0.0 0.0.0.0 DHCP

Vlan 10 DOWN 10.10.1.9 255.255.0.0 Manual

 

This is the same as the other switches now except for the fact that the state of Vlan 10 is down, and I can't figure out why, and can't seem to enable it. I can't find a command to enable it, so there may be a connection issue - the gigabit cables are plugged in and lit up on LNK but not ACT.

I can't connect to 10.10.1.9 via a web browser either, presumably because it's down.

Can you paste the output of show vlan. I'm thinking the vlan is down because you have no interfaces (ports) assigned to it. In fact after doing some playing around on my 3024 stack I would put some money on it.

 

If you aren't getting anywhere post or PM me a sanitized running config (show running config) of both a working and this new switch

[friendlytechnician]

Yep, show vlan shows there are no Ports assigned to Vlan 10.

I've PM'd you a running config of a current working switch and the new one.

Thanks for your time on this, it's been consuming me for days now. It's much appreciated.

 

*Edit* I tried PM'ing you but when I pasted the config all the spaces got removed. I didn't want to send you a mass of concatenated text.

Hi All, just for completion and in case anyone searches this thread in the future, Ghanel provided me with the solution.

I copied the existing config file from a working switch by connecting a serial link via Putty and using the command:

show running config

 

I edited the necassary names, IP's etc on the config and connected Putty to the new switch and pasted the config in. All the settings from the old switch have now been applied to the new one and I'm able to log in now via the web interface to do a bit of fine tune tweaking to the port settings.

 

Many thanks for your help guys, it's much appreciated.
