Okay, I'm not getting this

2 x 3024 stacked, OOB IP address configured as 192.168.0.11 (MGMT LAN)

I was scanning my network to do a cleanup of ip's in dns & dhcp when I noticed a strange ip, 192.168.113.160 (Our Internal LAN).

Low and behold, I logged into to it and found out it's my N3024's. So I opened up the .11 and yup it's the same device

Then I see it's showing a conflict on the .160 address. Network scan shows nothing else active on that port.

Run the Conflict Detect and yup still there. I've made a reservation in dhcp for that mac address to see if it moves but I still don't know why it is even using that address since there is no physical connection between the 2 lans except thru my workstation.

Anyone have any ideas?

I have two Dell M8024-k switches and they are driving me absolutely crazy. I recently placed them both in a stack for testing purposes (they're not in production). Now I want to just reset them to factory defaults as I've decided against using the stack. Here's what I did:

• Reset in many different ways - delete startup-config, clear config / wr, reset to factory from GUI, etc
• Removed stack cables
• Tried going through the initial setup wizard but I still end up with my switches in stacks
• Tried connecting via console to use boot options, console just doesn't work. 

Now what's happening is both switches are showing as Master, and when they boot up they go into their own individual stack, albeit in stand-alone mode. So, Switch A is Master of Stack A in stand-alone mode. Switch B is Master of Stack B in stand-alone mode.

Is this by design? Is their no way to completely remove the stack configuration from the switches and start from scratch?

Hello,
After created on Virtualbox the VM based on FTOS, I have tried to export to Vmware platform and doesn't works. Also I have modified the ovf file that is the description file but doesn't works.
Exists any possibility to simulate dell OS on Vmware? I need emulate on vmware because I must inspected a interoperability between Dell and Cisco.

Best regards,

I currently have 7 layer 3 switches. I have 2-n4032 switches for my backbone. I have 2-Dell n3024p switches in one closet. A HP Procurve in the server room and 2-Dell n3024 switches in the server room. The HP Procurve has ip routing enabled with 5 vlans. It is the orginal switch. I have added the n4032 switches which are also tied to the iscsi. I am wondering if I should configure each switch with ip routing and a ip address for each vlan on each of the switches. Or do I let the Procurvedo all the routing and setup the other switches as layer 2.

Hi,

we have a Dell Networking N4032F Switch with Dell OpenManage Switch Administrator Version  6.0.0.8.

Since SHA-1 is not supported by browsers in 2017, I would like to change the certificate to SHA-256 or higher on the switch. 

What OMSA version do I need to generate a SHA-256 CSR? Or is there another way, like uploading key+certifacte from openssl?

I've just received 5 pc6248s and I want to build them into a stack.

1. The switches are all used so do I have to factory reset them before building them into a stack?

2. From what I read in the Dell Technical White Paper I have to power up the switches sequentially (the manager, the stand-by,...). Do I have always to power up the stack that way or is it just applied one time when building the stack?

Thanks all.

Hi All,

I wanted to establish what is the preferred QoS configuration for a 2048P switch that connects to Cisco IP Phones

The Cisco phones mark their own voice signaling and voice bearer packets with DCSP values 24 and 46 respectively.

In this scenario, I would apply the configuration globally so that it applies to all interfaces and uplinks.

classofservice trust ip-dscp

classofservice ip-dscp-mapping 24 5

classofservice ip-dscp-mapping 46 5

cos-queue strict 5

or......

classofservice trust dot1p

classofservice dot1p-mapping 3 5

classofservice dot1p-mapping 5 5

cos-queue strict 5

I assume the above configurations will trust/honor the dscp value of the incoming packet and place them in a strict priority queue?

Phone interface configuration

switchport mode general

switchport general pvid 205

switchport general allowed vlan add 205

switchport general allowed vlan add 155 tagged

switchport general allowed vlan remove 1

Many thanks

Hello,
We are trying to setup two N3048 stacked switches and we have trouble with ACLs. We need to define ACLs on every VLAN and thought that rules are applied just in case that packet is leaving vlan or it is entering the vlan but we found out that if there is one pc connected to switch port in vlan and we are trying to create ACL with rule enabling ping to this PC, we also need to create second inbound rule to enable the PC to answer. It looks like switch is applying inbound ACLs also to packets going from PC to switch port. Is it normal?

In this case if I have PC with IP 10.1.180.20 in VLAN 5 and I'm trying to ping it from other vlan (there are no ACLs in other vlan), I need to create:

ACL bound to VLAN 5 as inbound

rule 1
permit ICMP packets from any to 10.1.180.20

rule 2
permit ICMP packets from 10.1.180.20 to any

Is it really like that? If I remove second rule, I'm not able to ping 10.1.180.20 from other VLAN. On router I can use instead of second rule something like permit established connections ...

That you for reaction.

Best regards, Oldrich

I have a system I am trying to configure. I have a dell N3024 external switch and a Forcepower 10 switch connecting to a server. There are 2 separate systems. System 1 works just fine but the same syntax in system 2 does not. Im not even receiving connectivity lights on the N3024. Any suggestions or guidance ?

I have 2 PowerConnect M8024-k blade switches in a stack configuration (although this issue was also occurring without the stack). 

I am setting the clock manually with the clock set commands, but every time I reload the switches, the clock settings are completely lost. I'm saving the config before reload of course. I'm not using any SNTP, I'm just simply setting manual local time.

Is there a solution to this?

Hi ,

I am having issues with ARP broadcast from our network devices which has Failover virtual IP configured for 2 x physical NIC connection.

Our setup is 2 x DELL N3024F switch connect to 02 x DELL 6224F switch. Default VLAN 1.

a. DELL N3024F switch is not stacked, it has VRRP configured for L3 routing

b. DELL 6224F switch is stacked with port -channel Link Aggregation 

c. Port Gi1/0/2 on DELL N3024F SW-01 connect (RJ45) to 1/g1 on DELL 6224F SW-01

d. Port Gi1/0/2 on DELL N3024F SW-02 connect (RJ45) to 2/g1 on DELL 6224F SW-02

Logging message received sample:

Nov  xx 10:20:36 172.168.XX.XX-1 ARP[ipMapForwarding]: ipmap_arp_api.c(1149) 391233 %% Received ARP Reply on interface Vl1 with bad target IP address 255.255.255.255. Sender IP is 172.168.XX.XXX, sender MAC is 00:25:97:XX:XX:XX.

These messages flooded and caused DELL N3024F switch to disconnect interface Gi1/0/2 port from DELL 6224F switch. Everytime this happens to either DELL N3024F switch, I have to power reboot the affected switche to get the connection up again.

Am i missing some configuration not properly done for DELL N3224F switch?

DELL 6224F switch is not showing any errors for the same ARP broadcast, and most of the devices is connected to through it.

Thanks for your kind advice and support.

Is there a way to access the boot menu on a M8024 though the CMC console redirect? Bought a used switch and I am unable to log in and need to reset the password and all the settings. If not will any usb serial cable work or is there a specific one I need to use?

Thanks!

The existing config is:

interface Gi1/0/20

speed 1000

description "WifiLocation2"

switchport general allowed vlan add 154

switchport general allowed vlan add 153 tagged

switchport general allowed vlan remove 1

switchport access vlan 15

lldp transmit-tlv sys-desc sys-cap

lldp transmit-mgmt

lldp notification

lldp med confignotification

voice vlan auth disable

I need it to look like:

interface Gi1/0/20

description "WifiLocation2"

switchport access vlan 15

I have tried quite a few things but cannot get rid of the switchport lines

any help would be appreciated

Hi,

I am considering enabling 802.1X on N2000 switch on a port with Phone & PC connected and need some clarification on the subject of behavior of this setup.

I want to treat the Phone as 802.1X unaware client. So according to N-series User Guide, I should choose 802.1X MAC-based authentication with MAC-bypass (MAB). It is stated that when port is configured with MAB it will check first if connected client responds to EAP Request. If no EAP Response, then it goes with MAC address.

Now, let's assume the Phone has booted and is up and running. Now we plug in PC behind the Phone.

1. Will that PC be able to do 802.1X with Active Domain credentials username & password (EAP Request/Reply) or once the port on a switch is set to MAC-based auth it will always need to authenticate with MAC address only?

2. Will Dynamic VLAN Assignment with attributes returned by RADIUS work assuming port in General mode?

Thanks,

I am having issues with the time convergence in this solution. Basically, I have two N4064F in MLAG and running VRRP. Everything works fine, but the time is killing me.

Sometimes it takes 5-12 seconds establish the communication and we have voice in this site. So, we lose the voice while the protocols do their recalculation. It works like this: if we disconnect one of the switches simulating a failure, sometimes it doesn't lose packets, but when reconnect the second switch they do the calculation for both protocols, and we lose connection for 5-12 seconds. Sometimes, We lose packets when we disconnect the switch, but after the re-connection, it will lose one packet, and that's fine.

S,o I need a quick recovery after failure, and after second switch recovery. I have tested all the parameters in VRRP and MLAG: decrease timers, change priorities, disable preempt, and decreasing STP timer, but the result is the same. I not sure what else to do. When I call Dell, they send their guides for MLAG and VRRP. I already followed all those procedures, but the result is the same.

Here are my configuriations:

HI Guys,

we have a bunch of N1548p in our office and our new project is to set RAdius authentication in those switch, my question is how can i configure the switch in case my frist radius server fail it try to authenticate in my radius server backup ?

best regards,

Hi,

I currently have four 3548p switches and a Mitel 3300 telephone system. At present we have a simple flat network but as things are expanding I would like to separate the telephone traffic using a Voice VLAN. Our computers are connected via the data port on the desk phones so are not using separate switch ports, i.e. the computer and phone on each desk shares the same switch port.

I've never done this before so wondered if anyone would be able to help with basic, step-by-step instructions on setting this up, preferably using the GUI.

As I said, I am very new to this so am feeling my way through this. I can see the Voice VLAN section in the GUI but a lot of the options are greyed out. Dies that mean I need to set up a VLAN first before making it the voice VLAN?

Any help would be most appreciated.

I do not have Jumbo Frames enabled on any device on my network but I am continuously getting Jumbo Frames (which show up as errors on one of my switch stacks) and I have no idea where they are coming from.

I have connected the PC that I have Wire Shark on to the receiving switch stack but the switch is dropping the jumbo packets as errors so I do not see them. I have connected the PC to the switch stack that the packets would be the sending switch stack and I still have no idea where these packets are coming from.

Any advice? 

My DHCP server is configured with all the scopes and option 156 (configServers=1.1.100.10, ftpservers=1.1.100.10, country=7, language=4, layer2tagging=1, vlanid=100) which is required for our Shoretel VOIP phone system.

When I plug a PC into any port I receive a VLAN3 IP as expected, if I change the PVID to 100 I receive a VLAN100 IP as expected, however when I plug a VOIP phone in I get a DHCP server Timeout message, I am really stuck on this issue now , any help would be greatly appreciated.

See the switch configs below:
