Hi,
One of our 4810 is logging a lot of theses:
%STKUNIT0-M:CP %ARPMGR-6-MAC_CHANGE: IP-4-ADDRMOVE: IP address 10.0.200.88 is moved from MAC address 7c:d1:c3:dc:e0:a1 to MAC address 2c:59:8a:19:da:a1.
Most of the IP's affected are on a power connect POE for my Aruba AP's, probably a coinincidence, but...
Can anyone explain what is going on with that logging?
Thanx,
Dany
I've set up a link between a N2048 (Tengigabitethernet 1/0/2) and a N4064F (Tengigabitethernet 1/0/48) with a DELL DAC. These two switch are configured with MTU set to 9216 on each switch.
But on the 2 ports involved in this link I get a lot of :
On the N2048
# show interfaces counters tengigabitethernet 1/0/2
Received packets dropped > MTU: ............... 303283
Transmitted packets dropped > MTU: ............ 155494
On the N4064F:
#show interfaces counters Tengigabitethernet 1/0/48
Received packets dropped > MTU: ............... 147596
Transmitted packets dropped > MTU: ............ 221817
I do not understand why this occure as MTU is the same for the 2 switchs. Any idea ?
Thanks
Patrick
Storage Spaces Direct is a nice new feature in Server 2016 that lets you do fail-over and redundancy without a SAN. Traditionally your nodes would be connected to a SAN and if one node went down the other node could pick up the VMs that died and carry on. S2D is different, where by there is no SAN, but a bunch of SATA/SAS disks in each server.
Each server holds a copy of its data, and a mirror of the other server's data. If one node goes down then the other node can failover the VMs and carry on with its locally held copy of the VM data. When the downed node comes back up, data is resynced between servers; no SANs are involved!
To do this we must use 10 GbE nics in the servers and in the switches too. I have two Dell T630s hooked up to two Dell S3048 switches and things are not working nicely. I can do live migration between nodes, but when I shut one node down its VMs migrate over to the other node, but then it loses sight of the CSV folders and of course the VMs then stop (enter pause state).
We have to enable the Data Center Bridging role (among others) on the servers and configure the their 10 GbE NICs like so:
# Enable Data Center Bridging (required for RDMA)
Install-WindowsFeature -Name Data-Center-Bridging
# Configure a QoS policy for SMB-Direct
New-NetQosPolicy "SMB" -NetDirectPortMatchCondition 445 -PriorityValue8021Action 3
# Turn on Flow Control for SMB
Enable-NetQosFlowControl -Priority 3
# Make sure flow control is off for other traffic
Disable-NetQosFlowControl -Priority 0,1,2,4,5,6,7
# Apply a Quality of Service (QoS) policy to the target adapters
Enable-NetAdapterQos -Name "Mellanox 1","Mellanox 2"
# Give SMB Direct a minimum bandwidth of 50%
New-NetQosTrafficClass "SMB" -Priority 3 -BandwidthPercentage 50 -Algorithm ETS
# Disable Flow Control on physical adapters
Set-NetAdapterAdvancedProperty -Name "Mellanox 1" -RegistryKeyword "*FlowControl" -RegistryValue 0
Set-NetAdapterAdvancedProperty -Name "Mellanox 2" -RegistryKeyword "*FlowControl" -RegistryValue
On Lenovo switches, we must do a "cee enable" to enable Priority Flow Control
In the "S4810 Switch Configuration Guide for EqualLogic SAN" Dell i see commands like "dcb enable" which my S3048 doesn't have.
So does anyone know if my Dell S3048 switches are suitable for using with Storage Spaces Direct (S2D)?
Thank you for your time.
Hi everyone. I'm setting up a Force10 S4810 and Dell N3048. I'm having trouble figuring out how to trunk the two together. They will be passing severval VLANs (10,12,16,20,24) so the confusion between trunk/hybrid on the S4810 side and general/trunk on the N3048 side is getting to me. What would be the correct way to trunk both switches together using one port on each and passing the multiple VLANs? Thanks.
I have eight Powerconnect 6248 switches, two stacks of three and two single switches. I use Lansweeper for my inventory and whatnot. One stack is not displaying the assets attached to the stack like the other are. I used the SNMP interface debugger and narrowed it down to SNMP V1 scans correctly but SNMP V2 does not. To the best of my knowledge, SNMP V2 is configured on this stack and it used to scan correctly. What troubleshooting steps could I take to get SNMP V2 working properly for this stack?
Hi
After I get a New N4032F switch I can assign an IP and default gateway to vlanXX, then if I recover the device to redeploy it using another vlan....lets say vlan1 and try to assign it an different IP it would take it
I get this warning
Warning! Notice! The configured default gateway will not take effect until an interface belonging to
the same subnet as the configured Gateway is created and activated.
I have deleted the existing config and reset it back to factory defaults and it still cannot ping itself
Please Help

I currently got the Dell 6224 switch and Sonicwall NSA 3400.
currently there is no VLANs setup. I need to create a seperate VLAN "2" for the guess wireless network . This is my plan:
Sonicwall Internet Port 24 on the switch. Needs to allow all vlans to pass and also add VLAN 2 to it.
Three ports on the switch need to pass VLAN 2,and all VLANS
Port 19 on the switch is connect to my DHCP Server that needs to pass all VLANS and also pass VLAN 2 which will have its own DHCP Range running just for VLAN 2.
I am windows admin and currently not so good with networking command lines. I was hoping someone could advice me on this.
Thank you
Hello,
As workaround solution VSS-Cisco and VLT - Dell should live together. Someone proofed this solution and worked fine? In this way like 2x6500 works like unique only would exist one LACP configured in Dell site.
Thanks,
Hi! I've the following configurations:
vlan database
vlan 100 name data
vlan 200 name voice
voice vlan id 200
I need to on my ip phone, run the data vlan 100 on the port "PC" and on it has the voice vlan 200 for ip telephony I usually use this command on CISCO routers:
Fastethernet interface 0/3 (the phone is connected here) Switchport mode access Switchport access vlan 100 Switchport voice vlan 200 Spanning-tree port fast But how do I configure this in dell powerconnnect 5524 ?? I will thank you for life
Hi,
I've been given the task of setting up a simple colocation but my knowledge of setting up managed switches is a little limited.
I've been given the below IP info by a single network drop into a rack.
Public IP - 1
Public IP - 2
Public IP - 3
Gateway - 1
Subnet mask 255.255.255.248
Current server setup in the rack.
Linux Server 1 with Public IP - 2
Linux Server 2 with Public IP - 3
My aim is to setup the Dell N2024 so that the network drop connects to the switch and then can pass traffic to the servers.
My thought was to setup the switch with a private address for example.
IP - 10.10.10.1
Gateway - 0.0.0.0
Subnet mask 255.255.255.0
Then setup a vlan for the three public IP's above.
Is this the correct way to complete this task?
It seems simple enough but i'm being thrown into it with no guidance so some steps or advice is welcome.
Thanks
hi everyone:

Hello all,
can someone give me a hint on how to enable debug messages in a telnet session on a PowerConnect 8024F switch?
I configured 'logging monitor debugging' and then set 'terminal monitor' in the session. After a 'debug spanning-tree bpdu', lots of messages should appear, but they don't. The first lines of 'show logging' are:

hello
I have 2 stacks of 55xx switches linked by fibre with the Dell N743D 10Gb/s SFP+ transceivers
I need to add a third location , unfortunately the 55xx series are no longer available
I have been searching for info on interoperability with the replacement series the n2000
can I simply connect an n2000 to one of the 55xx stacks using the same modules ?
I have a Dell N1524 with Code Version 6.2.6.6. I'm monitoring the Interfaces in a Software, and it is showing me RX Errors and discards in one port. In this port I have an Access Point Ruckus, but the users does not have any connectivity issue.

How can I diagnose what is causing this packet discargs?
Hi All,
Please bare with me as this is my first post on Dell forum :)
I am currently running a QinQ setup for a client as they require a L2 service from us.
For all intents and purposes lets say the setup is as follows: Router1 > 8024F-1 > 8024F-2 > Router2
R1 is sending tagged traffic on vlan221, and connects to SW1 on port Te1/0/24Sw1
Te1/0/9 connects to SW2 Te1/0/9
Traffic coming from Te1/0/24 should be encapsulated into Vlan999.
Vlan999 get stripped on Sw2 port Te1/0/24
S-tag: 999
C-tag: 211
Configurations I have thus far is:
SW1
configure
vlan database
vlan 999
exit
########### Accepts all incoming traffic and applies additional Vlan Tag
interface Te1/0/24
switchport mode general
switchport general pvid 999

switchport general allowed vlan add 999
exit
########### Accepts VLAN 999 traffic and sends as Tagged Traffic

We have a Hyper-V 2012 R2 Cluster with several host nodes, which are all Dell PowerEdge Servers, connected to two PowerConnect 5524 switches, in a Master/Master-Backup setup, which are in turn connected to a MD3220i SAN.
The idea of this setup was that as long as only one piece of hardware failed then the cluster services would still successfully run.
This was working fine until the other day when the power went out for one of the switches and one of the power supplies for the SAN. This then led to a loss in connectivity between some of the cluster nodes and the volumes within the SAN.
The SAN did lose some connectivity but it remained powered on throughout so we don't believe this is the point of failure. Looking at the logs on the switches it appears as though there was a complete loss in connectivity for the Master. However this begs to question, is this truly a fault tolerant system.
Upon some investigation it appears as though some others, who have a similar setup to us, have found there is a loss of connectivity as the master-backup takes the place of the master switch. There has been mention of using an option called FastLink/PortFast which might speed up the process and thus make the likelihood of failure of connectivity lower.
Anyhow, does anyone know how the switches should be configured in order to ensure that our services are fault tolerant?
Thanks in advance to any replies.
I am trying to learn about network switches and need to correct something I messed up working with a Dell PowerConnect 5448. I was trying to change the static IP address of this switch and instead of changing it, I removed it. Now I can’t manage it from the web GUI anymore. The switch is still working fine on our network, but it hasn’t been rebooted yet so I’m mildly concerned. I’m guessing what happened is I just removed the management IP address of the device and now I need to manage it from the console cable only.
What I did:
So my question is, how can I connect to the switch to set the IP address without losing its configuration? I have a null modem cable.
Hi,
I'm new to the group and networking as well..I've acquired the following equipment.
1 Dell 8032 with 1 QSFP-R Stacking Module 5KFVW
1 Dell 7048R with 2 J3PC9 10 Gbe SFP+Ethernet Module
1 Mellanox SX6036 Switch..
2 Volex QSFP+ to Quad SFP+ 2.0M Passive Cable VAHS-30-0428-2M
6 MC2210130-002. Mellanox Technologies 2M 40GE QSFP Passive Copper Cable 30AWG
I've tried to connect the SX6036 switch to the Dell 8032 5KFVW module via two of the mellanox QSFP cables and I don't get any activity or link lights on either switch. I've also tried connecting the 8032 5KFVW module to 7048R J3PC9 module via the Volex QSFP+ to quad SFP+ cable and the activity leds flash on the 7048R J3PC9 but no activity or link leds on the 8032 5KFVW module..
So am I having issues due to bad configuration on the switches? Incompatibility between the cables? Or can these switches not be connected in this manner.
Being I'm new to the whole networking thing, I was kind of hoping this would be more or less plug n play, but I'm guessing that isn't the case..
Please Help..
Thanks in advance,
Rob
