Reference Dell PowerConnect 8024 - 802.3ad (dynamic LACP) through 2 switches?
We evaluate the use of switches Dell PC8024 to upgrade our backbone to 10GbE. We use currently HP ProLiant servers with multiple network cards are associated. The servers support 802.3ad HP dynamic aggregation of links (LACP).
The switch PC8024 does support the aggregation of dynamic links through 2 different switches, or should it be on the same switch?
In comparison, the HP2910 switches can support aggregation (LACP) dynamic links across multiple switches, while the HP2920 switches can. If some can, some can't. Need to understand the ability of the switch to PC8024.
Thank you!

Hello Terry,
The 8024 does not support a SHIFT of two different switches, the only way it would work, if the switches are stacked and effectively a single switch. If you have used the new series N4000 they take over MLAG, allowing for the OFFSET will be in both switches and they communicate via a peer.

What Dell switches are suitable for VMware?
We will have a very simple vSphere environment. What switches should we buy? Must be Dell. I am a newbie in networking, but I'm a PCV.
2 x ESXi hosts in a cluster HA/DRS 5
vCenter Server will run as a virtual machine
We will be using VLANs for security
We will use a pair of resilient switches
No storage traffic will go on these switches, only management, vMotion and VM Networking
The data center will provide a managed firewall. There will be no other switches.
X 2 Dell PowerConnect 2848 switches would be enough? They can carry traffic between the VLANS? Or do we need more expensive switches?
Sorry for the newbie question!
From what I can find on the Dell Web site, the PowerConnect 2848 switch isn't a layer 3 switch, so it would not be able to carry traffic between the VLANS. To route between VLANS, you will have them either need a dedicated router, or you'd need switches with 3 as the PowerConnect 6248 switch layer routing capabilities.

EPS-470 for power and switches Dell PowerConnect - 2 outputs or 1?
I do some design network (including the grids and the PDU. In many cases, I need a power supply EPS-470 to provide PoE to 48 ports on a PowerConnect switch.
I need to know, do I need an output for the switch and the other to the EPS-470, or once the switch is hung in the EPS-470 just do I power connected to whom? I just need to know if I need one or two points of sale so I plan accordingly for the PDU.
Hi prepIT,.
The EPS-470 adds more power, so you need two, one for the switch and the other to the EPS.

Connection SAN Dell PowerConnect 6248
Our switch in our network is the Dell PowerConnect 6248. This switch has a SFP module.
I was wondering if I could use this module to connect my SAN [activeRAID 32 TB of storage active destocking] and have access to the storage as a network or NAS drive Bay.
To be more precise I'll be plugging the controller [HBA] San to the SFP module on the 624 of Dell PC via a cable Fibre Channel LC.
I'm new to SAN configuration and look for the best solution to access the storage on my network.
Everyone has implemented a San with the SFP Module before; If that set up your look like?
Fibre channel and ethernet/IP are not compatible protocols without another device that can translate. The 6248 has no support for FCoE. There are switches that support both they are called network switches convergent or unified, although generally the traffic is still separated.

Difference between Dell Powerconnect N4032F and 8132F
Hello!
In the last days, the Dell PowerConnect 8100 disappeared from the Dell Web site and now, the M4000 series with the same characteristics are presented.
It's just a change of name or these devices differ in some way? The M4000 firmwares is usable on 8100 switches in the future?
Thank you
Kind regards
Stril
Dell PowerConnect N4000 switches series both Dell Networking PC8100 series share the same version of the firmware of the image (for example, N4000v6.1.0.1.stk). The Dell Networking N4000 series switches can be stacked with switches Dell Networking PC8100 of the series with any battery necessary for the performance of 6.0.0.8 or later firmware (6.1.0.1). Dell Networking PC8100 switches can support the firmware both 5.x and 6.x versions, but Dell Networking N4000 can support only the 6.0.0.8 and later versions of firmware (6.1.0.1)
I hope this helps.

Reference Dell PowerConnect 2848 OID for CPU time and memory
Hi all
This is my first post in this forum. I searched all the messages that can solve my problems, but I could not find so if there is already an existing post and I couldn't find it please guide me to it.
My case is. We have a few Dell PowerConnect 28xx switches in our network. We want to monitor things like the CPU, the temperature, the use of the RAM usage. We use Solarwinds IpMonitor monitoring tool. I downloaded the MIB, I could find the download of Firmware from Dell drivers and downloads page. I went through the entire MIB, but I couldn't find an OID for the foregoing.
So if anyone can help me please what OID is used for usage of CPU and RAM temperature it will really help me.
Please let us know in case we need more information on my side.
Thank you
Frank Moreau

Dell PowerConnect 6248 10 GB ports reference works do not
Hello
We have recently installed a module SFP + (part # c107d) in our Dell PowerConnect 6248 switch. The switch does not seem to see the module because before install us the plug-in, it showed a port xg3 xg4, and after the addition of the module, it shows that these ports.
So I have a few questions:
Is the SFP + above compatible with this model of switch?
If so, how can verify us that the ports are active?
Here is the result of the port details:

Yes, this module is listed as compatible with the switch. It seems that you install in Bay 2? He may have listed these ports but they probably do not appear as active. Have you tried to make a connection with ports?

Reference Dell PowerConnect 2824 remove connections, odd led models
Hello
We are noticed on some of our Dell PowerConnect 2824 switches that our devices are connected to the switch suddenly disconnected. Our devices are a network of small size with the switch, where we connect up to 12 devices and use DHCP to assign IP addresses to the devices. We also monitor the network with a Windows laptop. We have also seen times where the switch itself seems to be restarted and shows amber LED light up successively from left to right on the top row of ports, then return on the bottom row. I confirmed that we use version 1.0.0.45 software for the switch in question.
We have also seen situations where all, except one device remains connected, but when trying to reconnect to the device has fallen, it seems that the switch seems to completely ignore the device regardless of the port where we connect to the switch. We tried other cables, but the problem persists. It's the kind of behavior that I could wait if the MAC addresses are not unique, but all of our devices have all custom MAC addresses.
Another issue is that we use a very short lease period of one minute. I don't know if this will get us in trouble.
If you need more specific information, I'll try to answer your questions.
Thank you.
Bob
Hi Bob,
If it happens on several switches it is probably not a problem with the hardware switch. It could be a matter of Spanning Tree where it lacks a Hello and due to the lease really short DHCP is originally from the port to close before it can restore a link. You can try to turn STP or enabling quick link on the ports for end devices.
Why do you have the DHCP lease on so little time for only 12 aircraft? It would add a lot of network traffic. You can try and have some machines on static IP and see if it still falls these ports.

Reference Dell PowerConnect 6024F get mac by ip with arp and more option
Hello in the DELL community.
I hava a little question, and hoping to find some answers here ;) I'm writing a small script, and in this script, I need to get the mac address is to link to Ip address of the ARP command. I am using telnet to connect to DELL. But the show arp command displays a lot of information, a huge list of ip. I tried to analyze, with the '
' option and press etc., but it's a very slow procedure. Two main issues:
1. how to get the mac address and link it to the IP by ARP command
2 how to get rid of the option '
'. I mean show cli without I thank the of to get answers.

historyHe might have an OID you can pole for this info. all the OIDS are in the MIB that are included in the download for the firmware.

If you do not find one in the MIB, you might try a SNMP walk on the switch to see if you can identify an OID that will provide you with this info.

PowerConnect switch and Cisco routers
I have 4 Cisco routers connected to our Dell Powerconnect 7024. This is a laboratory environment where I'm having every act of router (2 per site) as a WAN gateway for these 2 sites.
Site 1 Site 2
2 3 router
PC - Dumb_switch PowerConnect Dumb_switch client - PC Client
Router 1 router 4
There are a few other Vlans on the switch with connected devices. With the current configuration, these two sites can communicate with any other "site" connected to the switch on each route, with the exception of the other.
Directly connected to the router interfaces are in trunk mode, as it's the only way I could get the dell to connect with the Cisco. Ive read in other threads that the general mode is usually suggested on the powerconnect switch, but had no luck with this configuration.
Router 1---> item in gi1/0/15 (vlan 10)
Router 2---> item in gi1/0/14 (vlan 11)
Router 3---> item in gi1/0/22 (vlan 16)
Router 4---> article gi1/0/23 (vlan 14)
Example: a ping from Site 1 can reach int 22 of the switch without problem, but I can't ping jump according to R3. As all the other devices on this switch can talk to these sites, I'm not clear if the problem is my config switch dell or routers. Any input would be greatly appreciated. Thank you!

Update Firmware on Dell PowerConnect 3548p
Hi all
I have dell Powerconnect 3548p and I want to update via telnet and I was wondering what the commands are as I tried those on the CLI manual.
I made a connection with success of my tftp to the switch and vice versa.
I am aware that this is possible through the web management, but I would like to know how to do this via PuTTY.
Thank you
You can update the firmware and boot code by using the command copy. Here are the commands that will be carried out.
Update the boot Code and firmware

Stacking Module - Dell Powerconnect 6248
Hello. I have a Dell Powerconnect 6248. This used to be a secondary switch in a stacked configuration (total of 2 switches). However, the captain then descended down we unplugged and it became the master of the battery. It is always configured in a configuration of the battery.
My question is this: can I remove the stacking module card when the switch is on and in production?
The reason is that I bought a new 6248 and repaired the old master as well and want to stack these two because they are both on the latest firmware. What is the best practice for this that I don't want to take down the switch by disconnecting the battery module.
Let me know if you need more information!
Thank you very much for any information!
Unfortunately the stackable modules are not hot-swappable. You must turn off the appliance to remove the stacking module.

reset the password on a Dell PowerConnect M6220
Hello, I'm trying to reset the password on a Dell PowerConnect M6220. Can connect to the CMC via the https Web page, I don't see how to do it from there.
Then I'll try to plug a USB serial cable into the console port and reset the password via a console session using teraterm but when I do that all I get is a white screen.
Parameters of the series are:
Cable: The Null Modem
Bits per second: 115200
Data bits: 8
Parity: None
Stop bits: 1
Flow control: no
Any ideas on how I can access telnet access to the device to reset the DDT successfully
Thank you
Kevin
You can connect to the console port internal to the switch via the CLI of CMC
Telnet to the CMC, then connect switch-a1 (a2 or b1 etc. etc.)
This will give you the > invites, so either delet the startupconfig and recharge it, or put into you own username and password - remember that you can set on the schema of the interface of the band or band in slecting the appropriate interface

Battery in gray on my computer icon portable gateway nv52.
Recently, I turned on my laptop after it is turned off for a long period of time and the battery icon is not only dimmed and impossible to reactivate, but I have no idea how it happened in itself because I made NO CHANGES at all. How can I fix it!
