PowerConnect 5548, 5448, 5324

$

0

I have a stack of powerconnect 5xxx series switches.  Each switch has its address in the 192.168.5.x range.  This is on VLAN5.   All switches have two dedicated trunk ports in a LAG group that connect to a TOR switch. (5548)

I'm able from a pc at 192.168.1.x , vlan1, to access other servers, printers, etc, on vlan5 within the 192.168.5.x range, but I'm unable to access any of the power connect switches.

Any thoughts?


Dell 5448 and 5424 Switch - Completely Remove iSCSI optimization.

$
0
0

I have Dell 5448 and 5424 switches that were used for LAN/iSCSI traffic but now will be used exclusively for LAN traffic. A network consultant I work with recommended removing all iSCSI optimization to improve switch performance for LAN traffic.

I have read the following article: http://en.community.dell.com/techcenter/storage/w/wiki/configuring-a-powerconnect-5424-or-5448-switch-for-use-with-an-iscsi-storage-system.aspx

If I disable the global iSCSI optimization and remove the default iSCSI targets of 860 and 3260, will I need to reboot the switch or are the changes live instantly?

Are there any other configuration settings I need to check to be sure the iSCSI optimization is completely disabled?  I have Jumbo Frames and Flow Control disabled.

The changes will be done via the web interface and not the CLI. Will that make any difference?

PowerConnect 8024k - Copy startup-config

I have two PC8024ks that I need to run this code on:

copy tftp://ip/filename startup-config

My TFTP is started, I hit yes to continue and it thinks for a second and then throws back errors:

Error in configuration script at line number xx

This is saying that something is wrong with the config Im trying to upload, but I just pulled the config from an identical configured switch in the same chassis using:

copy startup-config tftp://ip/filename

Any insight as to why its erroring out?

Faulty gigabit interface on powerconnect 6248

Hi

I have a port which is not active anymore for some reason. the complete cable run tests just fine as well as the pc so it is definately the port. when i run the cli diagnostics it refuses to give me the cable length instead it says "not copper". when i look at the interface in detail i notice that it's state says disabled instead of forwarding like the other active ports. it is enabled though and also on auto neg.

Is the port physically faulty or is there another way to get it going?

5548P configuration question

$

Hello,

 

We have 4 Dell PowerConnect 5548P switches which are stacked. These two switches are going to be connected to desktops/notebooks and printers on one VLAN, and then some IP phones on a Voice VLAN. These switches are going to be connected to two 6248s which will act as core switches. Our physical servers will connect to the Core switch which will be another VLAN.

 

I think I have the VLAN config worked out, however, is there a best practice document or site for configuring these switches? Such as enabling Jumbo Frames, Flow Control, Tree Spanning, RIP, OSPF, etc?

 

Thanks.

Is it possible to use Virtual Link Trunking in a mixed Dell and Cisco environment?

$

Hi,

My service provider is Cisco and they provide the firewall and routers as a managed service. My internal network uses Dell Power Connect switches. In the past we had an issue where the ISP's spanning tree costs leaked onto my network and caused some network outages - I'm thinking of trying to use Dell virtual trunking protocol instead of spanning tree, but am not sure if this would be feasible in a mixed Cisco and Dell environment.

Please advise.

Thanks

8024F stack shows strange health info after FW Update to 5.1.0.1

$

Hi,

a two member 8024F stack shows strange health status after the update, although the stack seems to be fine and working. 

Take a look at a sniplet from show tech-support (look at the end). It clearly shows no stuff for the second unit. Also in the web interface it shows no stuff for second unit. At the power area it even says ERROR.

Special note: YES, the CPLD update was performed successfully on both units using local Console cable after the 5.1.0.1 update.

Is this a bug?

I already performed the whole firmware update once again (plus bootcode update) and i also tried swapping unit numbers and back again. no luck. i never ever seen something like that. 

Best regards,

Joerg

6224 + 10G Base-T, can't get links to come up

$
0
0

I'm trying to figure out what I'm missing here. I've been banging my head on this one and would be glad to learn it's something simple... my problem is, when I connect from the 6224 using either of the ports on the 10G Base-T module, I can't get the link to come up (no link LED's on the module, or the NIC).

Details:

  • Switch:
    • PowerConnect 6224
      • Bay 1: CX4 module (nothing connected in it at the moment)
      • Bay 2: 10G Base-T module (the only bay you can put one in)
  • NIC
    • Dell/Broadcom NexExtreme II 57810S Dual Port
  • Cable
    • 6E/550 MHz factory made patch cable, 10ft long (have tried others)

So, I am trying to do the most basic test possible. Just power up the machine and hold after the BIOS post (no OS, no drivers).

  • If I connect the cable direct from the module to the NIC, no link lights.
  • If I connect the (same) cable from port 1 to port 2 of the module (straight cable, auto-MDIX kicks in), I get link lights.
    • This says to me that my cable should be ok, and the module ports should be ok.
  • If I connect the (same) cable from port 1 to port 2 of the NIC (again, straight cable, auto-MDIX kicks in), I get link lights.
    • This says to me that my cable should be ok, and the NIC ports should be ok)
  • If I connect either of the ports on the NIC to one of the gigabit ports on the front of the switch, I get a link light.
    • This says to me that I'm not insane, and something works.

What am I missing here? Anyone got any further tests to suggest?

Thanks!

How should I configure Spanning Tree

$
0
0

Hi,

I have several core Dell switches using PowerConnect 6224s mostly - these ink into my provider's Cisco kit. We run several VLANs and have redundant links between stacked switches.

I've read up on spanning tree and have the following tasks:

1. Map out the network - including ID root bridge, root ports, blocked paths, max age and helo time

Once I've done my analysis information, I'm not sure how to best optimize the spanning tree config, so far I have:

1. Ensure RSTP is enabled on all switches
2. Ensure all edge ports have spanning tree port fast configured
3. Do not declare spanning tree port fast on links between switches
4. Force speed and duplex settings on all link ports between switches (I assume this is because auto negotiate takes longer?)

What I'm not sure about is:
1. Should I enable BPDU guard and if so, where?
2. Should I enable root guard and if so, where?

I've read Todd's informative article: http://en.community.dell.com/support-forums/network-switches/f/866/t/19465205.aspx

But, I'm not sure where\whether I should be configuring the guard options - am happy to provide additional info as needed.

Thanks

Procedure to installing RPS-600/700 for PowerConnect 5224/5424

$

Hi All,

I bought one unit of RPS-600 and RPS-700 for power redundancy for one unit of PowerConnect 5224 and 5424 respectively.

Two questions/doubts came to my mind and I hope some experts here could clarify:
1. What is the step-by-step procedure of connecting rps-600/700 (new) to PowerConnect 5524/5424 (live system) - e.g. power up rps-600 first, then rps cable on rps-600 then rps cable on 5524 etc?
2. With the step defined above, is there any downtime?

Thanks!

Cheers,
Elvin

Dell Powerconnect 3548P - Not pinging, or allowing access to web console

$

Hello,

    I am wondering why we are able to access our PoE switch via the http web console, I can connect via the Serial port and do the Dell Setup Wizard, we set all the information and our ip address for this switch to 10.0.3.192 255.255.255.0 with a default gateway of 10.0.3.1.  

Then if trying to ping it if always times out, and if you connect to it and change the pc ipv4 setting to point to it, it wont allow access to it via browser. 

Any suggestions or help would be greatly appreciated, Thanks. 

7048 Stack Weirdness

We are using two 7048 switches stacked with each 2 CX4 Expansion card with firmware 5.1.1.7.

Everything seems to be working allright, but.. and now its getting wierd... the Slot summary doesnt show one card on one of the switches:

              Admin   Power          Configured Card
Slot  Status  State   State             Model ID              Pluggable
----- ------ ------- ------- -------------------------------- ---------
1/0   Full   Enable  Enable  PowerConnect 7048                   No
1/1   Empty  Enable  Enable                                      Yes
1/2   Full   Enable  Enable  CX4 Card                            Yes
2/0   Full   Enable  Enable  PowerConnect 7048                   No
2/1   Full   Enable  Enable  CX4 Card                            Yes
2/2   Full   Enable  Enable  CX4 Card                            Yes

Also the show switch stack-ports is missing the installed link, we are missing the Te1/1/1 and the Te1/1/2:

console#show switch stack-ports

                 Configured  Running
                   Stack      Stack      Link       Link

Te2/2/1          Stack      Stack      Link Up      16
Te2/2/2          Stack      Stack      Link Up      16

It does show statistics on the not recognised installed module..... in the webpage it is shown as :

Stack Port Diagnostics : (null)

So, what to do now?. is it safe to re-insert the CX4 card and if so, is it hot plugable?. And how is it possible that there is going traffic through that card while it doesnt recognizes it...

Call Recording not seeing UDP

Good Day Gentlemen and Ladies

I have two DELL 3548P's that are not stacked but connected over g3 and g4, I have a single port (porte45) that is connected to a server that is using CallRex software to record phone calls off certain numbers.

I have port e45 set to monitor ports  below and I have NO spanning-tree on port e45

e47, e48, g3, g4. .

Ports e47 and e48 are a port-channel, to an up link distribution layer switch (gateway)

The only difference is recently we upgraded our network to a redundant one  EXCEPT  these switch, it used to be a single up link from an access port on e26.to a stacked pair, Since we put in a pair of switches I created a port-channel and am now forwarding traffic across a trunk to a pair of switches using VRRP. I configured e45 exactly how the old monitoring port was configured.

I need to get this working again But I am not to familiar with it and these are just network switches passing Traffic through a VOIP Server and also a Call recording server monitoring 5 extensions, everything works except the call recording, the NIC configured on the Server for QOS sees nothing

Can anyone give me a shove in the right direction

Network Configuration - ESXi, EqualLogic, 6248 stack, Power Edge.

Hi,

I've inherited the following setup:

3 - Power Edge R710 servers with 10 x 1GB nics each.

2 - PS6000 arrays (iSCSI) tied into two 5448 switches.

2 - Stacked 6248 switches connected to the hosts.

How would you guys recommend I configure the networking from the servers to the stack including VLAN's? I haven't been able to find any reference to this type of scenario that makes any sense so far.

Here's an image of how it's currently configured, note that FT is not a requirement:

vLANs for Public IP Assignment

$

Hello Everyone;

Overview: 

My ISP provided me with more than Public IP block i.e (192.158.13.1/24, 192.158.14.1/24)  that I would like to assign to my Hypervisor (Citrix XenServer) via vLAN isolation & make it accessible to my VMs to acquire public IPs directly.  (this is actually a requirement of the network I'm setting up).  

I would like to know if this scenario is possible to implement via Dell 6224 L3 Switch. 

Network Setup: 

- My ISP gave me one link feed to my rack that I'm using (I can assign any IP from both different blocks) that I was given. 

- Currently the ISP link going to my Dell Power Connect 6224 L3 Switch port 24 then going to my XenServer box port 15

- I have number of vLANS Setup on the switch that are represented to the XenServer therefore port 15 is trunk port.  

What I'm trying to do 

Since all VMs requires public IPs . 

1. on Dell Switch create 2 vlans 10 & 20 

2. Assign public ip to each vlan 

3. create route rule on the switch to foreword the traffic to ISP router

4. Add vLAN 10 & 20 to port 15 so my XenServer hypervisor can see the incoming traffic.

 My Current Status 

i'm unable to to have this working in this order can someone advice if the idea is correct to achieve this task  or I have to design different solution for this to work.  

Force 10 MXL question

$

Hey guys,

I have a quick question, but first let me give you my setup.

We are currently implementing a new m1000e chassis with 2 Force10MXL switches. Both of the switches are in the b fabrics. I have F10a(left B fabric) going to our N7k with port-channel 7, while F10b (right B fabric) going to our N7k with a port-channel of 8. There is no stacking between the two F10's, but are up and running active/active (with no live servers on them yet)

I am kind of confused because we have 4 servers in there (not live yet) and they are showing:

F10-A#show ip int brie

Interface                IP-Address      OK  Method Status                Protocol

TenGigabitEthernet 0/1   unassigned      YES None   up                    up

TenGigabitEthernet 0/2   unassigned      YES None   up                    up

TenGigabitEthernet 0/3   unassigned      YES None   up                    up

TenGigabitEthernet 0/4   unassigned      YES None   up                    up

 

 

Sw2:
F10-B#show ip int brie

Interface                IP-Address      OK  Method Status                Protocol

TenGigabitEthernet 0/1   unassigned      YES None   up                    up

TenGigabitEthernet 0/2   unassigned      YES None   up                    up

TenGigabitEthernet 0/3   unassigned      YES None   up                    up

TenGigabitEthernet 0/4   unassigned      YES None   up                    up

My question is I know both switches see the ports. How does the server know which port to go out? Is this configured within the server, or in the F10? Do I have to stack the 2 F10's with a stacking cable?

Configuring a LAG between stacked 6000 and stacked 5000 switches

$

Hi,

I have:

2 x 6000 PowerConnect (PC) switches - stacked, let’s call these 6PC_Unit1 &
6PC_Unit2

2 x 5000 PC switches - stacked, let’s call these 5PC_Unit1 & 5PC_Unit2

These switches have multiple VLANS

I want to create a LAG between these switches.Please advise if I've got
anything wrong, but my plan is to do the procedure below.

On
6PC_Unit1 run:


  1. Sw(config#) Interface te1/0/1, te1/0/2, te1/0/1, te1/1/2 (select
    ports1 & 2 on both stack members)

  2. Sw(config-if#) channel-group 1 mode active (enable ports with LACP,
    dynamic)

  3. Show interfaces port-channel 1 (confirm interfaces are in the port
    channel)

  4. Interface port-channel 1

  5. Switchport mode trunk
  6. Switchport trunk allowed vlan add 1,10,20,30 tagged

  7. switchport trunk allowed vlan add 10,30 tagged

Do the above procedure on 5PC_Unit1
(i.e. configure both stack members)

Connect the following cables up:

5PC_Unit1 port 1  to 6PC_Unit1 port 1

5PC_Unit1 port 2 to 6PC_Unit2 port 1

5PC_Unit2 port 1  to 6PC_Unit1 port 2

5PC_Unit2 port 2 to 6PC_Unit2 port  2

Effectively creating 4 links between 4
switches and 2 separate stacks. Would this be the correct procedure to follow?

Also, I’ve noticed a number of guides mention
setting the spanning tree mode of the port channel to portfast – however I’ve
also read this shouldn’t be used on inter switch links and SPT sees aggregate
links as a single link.

Please advise if this procedure is correct.

Thanks

 

 

How to map out a switch network manually

$
0
0

Hi,

I have a remote data centre that I'm trying to map out, without visiting the site and tracing cables. Given that I can access the address table on each switch, what's the easiest way to find out if switch A is connected to switch B? the switches in my DC are stacked, which complicates matters slightly.

For example when I look at my MAC address table, almost all of my switches have a single MAC per port, apart the channel port (I believe this is a link aggregate port) which shows MAC addresses belonging to Dell, Cisco and other devices. How do I know where the channel port plugs into directly? Whether it goes to a Dell switch or say a Cisco switch?

Thanks
