Hi All,

I am new to this forum kindly help me with below issue.
We brought new  Dell M1000e chassis with M I/O Aggregator switches, switch1 and 2.

each switch have 2 X 40 gig ports total 80 gig per side , switch-1 80 gig and switch-2 80 gig, these switches connected with 40 gig cables which got split in to 4 10gig cables and goes in to  patch panel and from there to upstream switch.

I got upstream connection from CISCO nexus 5k, network team configured port-channel,

i am trying to configure these switches in  PMUX mode,

I configured port-channel but port-channel status is down and mode is L3, how to bring the status active and mode to L2 ?

i provided how in configured with command below please help me.

We are in the process of setting up a serviced office. It could have up to 100 customers therefore 100 separate VLANs + other management and public VLANs. 

These customer VLANs should not be able to access one another (obviously devices on the same customer VLAN should). However there will be public VLANs that all customer VLANs need to access as well. 

There will of course also be an Internet Router/Firewall on another VLAN, that naturally all VLANs need access to for Internet Access. This VLAN also needs access to ALL vlans in case we need to NAT traffic into a device on any VLAN. 

What is the best way to achieve this segregation? Using ACLs seems impossible due to the scale (and on the N4000 there is a 100 ACL limit), so what options are available to achieve the above, while ensuring all routing is handled by the swtiching itself.

Core (L3) switches -> N4032 (stacked)

Access (in L2 mode) -> N2048 (stacked)

Good morning,

I am currently working on a project to provide the office I support with wireless connectivity that allows the users to also be able to access network folders and servers, as if they were connected to the Ethernet. We have a standalone Comcast router that we use to provide guest wi-fi access that is broadcast through our NetGear r6400 router. I would like to, if it is possible, either (a) have the netgear router's guest network configured as the VLAN and have our Cisco APs broadcast the signal throughout the office or (b) set up the Cisco WAP4410N APs to broadcast VLAN tagged packets from our Dell switches via the netgear router.

Any help would be greatly appreciated. I skimmed through documentation for the Netgear router, Dell 3548p switch, and Cisco WAPs and saw that they all have some sort of VLAN configuration capabilities, but I cannot seem to properly set up the VLAN.

In a LAG configuration, in order to pass vlan traffic, the port channel should be setup in Trunk or General mode while the physical ports in access mode or both should be setup in Trunk or General mode?

The N3048 has already the 2 10 GbE ports in the front in use. Cant find any SFP+ expansion module to put in the back....is there any available? 

Can find a ethernet module, but dont think there is a ethernet module available for the S25?

Hi,

I configuring two Dell C9010 Switches, and i was wondering, a way to configure the switches as one switch.

the switches are in VLT, and using one RPM on each unit.

my goal is to avoid configuring each switch at a time, for example,

when i created my VLAN on say core1, i don't want to create again on core2, and same applies for all configs.

kindly advice.

Thanks and Regards

Good afternoon,

I'm very new to Dell switches. These particular switches were purchased and installed by an outside organization. There are 4 switches in total (N3048P, N2048P, N2024P, N2048P) and they stacked 2 of them, the 2024 & one of the 2048s, with the 2024 being the 'master'. 

I was having issues connecting via SSH to these units and found that updating the firmware fixes the issue. I did the individual switches first with no issues and then the stack. The master in the stack updated completely, but the member switch (2048) will not update the CPLD to version 15. The firmware updated fine though.

The instructions say to connect to member switches individually via the console port, but, when I try, I get told that I can only connect to the master this way. What am I missing!?

Thanks!

Hi,

might be a stupid question, but according to the 

"User’s Configuration Guide Version 6.3.0.0 and Later"

there should be a reset button on the front panel, but there is none - 

at least nothing that looks like a pinhole or something similar. 

Since the web interface is not responding anymore, I want to reboot the switch.

Should I just remove the two power cables? Will the switch boot automatically then?

Any help is highly appreciated,

Thank you,

Henrik

HI All,

I am having issue with multiple vlan trunking between Cisco 3850 and Dell 7048P (code, 5.1.7.5)

There is a port channel Dot1Q trunk between both two, and this trunk is only passing vlan 1 traffic, not other vlans for some reason. 

Cisco 3850 config:

interface Port-channel30
 switchport trunk allowed vlan 1,80,100,105,650
 switchport mode trunk

Dell 7048P config:

interface port-channel 30
 switchport trunk allowed vlan 1,80,100,105,650

I even created SVI interface (vlan 100) on both side and still could not ping each other via SVI interface.

Not sure if anyone here had similar issue before. Much appreciated if someone can help. 

Thanks

Charles

Hi Team,

While configuring the Dell Switches (Z9100, acting as a Spine switch) we need to configure the uplink ports.

We are having around 6 VRFs.

The site router (to which uplinks will connect) do not want to configure the VLANs and want to configure L3 Subinterfaces for each VRF.

We have a port channel from Dell to Site Routers on which traffic for all 6 VRFs will be required to be configured.

Do someone have configuration to create L3 subinterfaces, where each subinterface will be part of one VRF,  for the port channel.

Thanks !!

Hi,

We've recently acquired a couple of Dell X1052 switches and I am looking to configure the ssh timeout.  I've seen other posts mention setting the exec-timeout, but there is no mention of how to set it in the 

Dell™ Networking™ X1000
and X4000 Series Switches
User Guide

I've entered the enable and config commands, but don't see any options for ssh, http or https to set the timeout value.

Any help will be greatly appreciated.

Thanks,

Paul

Hi.

I have 3x Dell N3048 working as one stack.

I need shutdown entire stack, what is the proper way to do that ?

And of course power on them back. I should power ON one node, wait few minutes, power on second, wait and power on third ? or power ON all three at this same time ?

Hello,

I have 2 Force10 S50 switches. When they were in the datacenter i was able to use the console port. However, now that they are home i want to reconfigure them for a new datacenter. The way i have it setup is USB to Serial > Serial to RJ-45> Rollover Ethernet cable. With this setup i can see output in putty but cannot type anything. If i use a straight through or a cross over it does not display anything. Can someone help me troubleshoot this. I never had so much trouble with getting a console port to respond to me. Both switches have the exact same issue so i know the switches are good. Must be my RJ-45. I've made it 3 times and no change. If i bring over a cisco switch my usb to serial and cisco cable work perfectly. I've tried the desktop and the laptop. 

Thanks,

Tom

I work at an electronics recycler and we recently received a large amount of 3524P switches. Normally I end up connecting a serial cable and reset all settings to factory defaults.

Here's the catch-- every switch we received isn't giving a serial output. My guess is that they ended up disabling the console port..?

I was able to find the IP address of the switch and confirmed that the web interface was working (although, I was not able to log in because I don't have credentials)

I am by no means an expert with network switches but I have been wiping switches for about  6 months now without coming across something like this. Here are my serial settings:

Baud: 9600

Data bits: 8

Stop bits: 1

Parity: none

Flow control: none

I would love to be able to somehow re-enable console access without having the admin login. Anyone have any ideas?
