PowerConnect 5500 / settings MTU S4810 Force10

It's probably a noob question so forgive me, but I can't find the answer anywhere. I am putting vCloud Director and in a number of places, it mentions: "physical infrastructure MTU must be at least 50 bytes more than the MTU of the machine virtual vNIC"

My problem is that I can't understand what the MTU settings on these switches are currently and how I can change them properly is what I need in the vShield environment?

I hope that makes sense!

Thank you!

Hi PSYOPwarrior,

The standard size of mtu is 1500. Page 638 ftp://ftp.dell.com/Manuals/all-products/esuprt_ser_stor_net/esuprt_powerconnect/powerconnect-5548_Reference%20Guide_en-us.pdf

You can use the command port jumbo-frame to allow larger images.

The default value is the Force10 1554 http://www.force10networks.com/CSPortal20/KnowledgeBase/DOCUMENTATION/CLIConfig/FTOS/S4810_CLI_8.3.12.0_28-Aug-2012.pdf

Transfer the PowerConnect switch settings to N3000

I am trying to copy paste the settings currently, we run in a for a new N3048 PowerConnect 6448.

Unfortunately, it seems that many commands use the same syntax they used to have. CLI reference guide did not help much, because it is not compare or tell me what commands are the same for PowerConnect to N3000.

Creation of the VLAN between Powerconnect 5548 and F10 s4810...

In the coming months we will replace our network equipment. I was able to get their hands on the new gear at the beginning, and if I'm not traditionally a guy from the network, the project has been given to me and I started playing. The first thing that I wanted to work on was implemented VLANs. I have configured the switches like the picture below:

When I have IP every PC connected to the same subnet and apply VLAN10 to their respective ports, they aren't to pings within the same stack or between cells. My basic understanding is that they are, do they not? Did I miss something in my understanding of VLANS or is there a problem with my configs? I posted the configs below.

I would say lets start with one side and obtain communication of work between the two computers on the same stack at RTTMOACCESS01. The port settings for the 1/01 and 2/01 look great both in access mode for VLAN 10. Which IP addresses and subnets you assign to computers?

5548 to battery power battery connection 10 also appear to not be in a LAG, then we run two connections like that and they aren't in a SHIFT, we create a loop and a single connection will enter a blocking state.

For the connections between the 5548 and force 10, I suggest to turn them into a GAP. The command should look like this.

Console > activate

Console # configure

Console (config) # (config) # interface tengigabitethernet 1/0/1

Console (config) # port - 1 automatic mode group

output console #.

Console (config) #.

Do the same for Te2/0/1

Then we set up this OFFSET to set it up, and I would try to use the trunk instead of general mode mode.

Console (config) # interface port-channel 1

console switchport mode trunk #.

console # permit trunk switchport vlan add 10,20,30,40,50 tag

The same should be done for the Force switch 10.

Te0/46.1/46 in a SHIFT

Te0/47.1/47 in another SHIFT

Put in the trunk and let the VLANS on the trunk.

Allows to study these settings and see if we can make any progress.

Thank you

Switch Cisco Nexus 6004 removes more than 300 bytes IP packets

Hi all

We have a circuit of wave level 3 10 G running between two switches Cisco Nexus 6004. The circuit came online between our two data centers (in the same city) without problem.

When attempting to ping to the remote-end 10G interface, it works very well with packets of 64 bytes. CDP is enabled and that we see the CDP information remote switch. However, if we increase the size of the ping to more than 300 bytes packets, we lose 1 in every 20.

We settings MTU verifed, type of cable of 10G and duplex settings.

Level 3A tested clean and we will move forward with more testing.

Any ideas on the problem? We feel the carrier out and end to test with their testers. But so far, the circuit's own test. I was not sure if it is something related to Cisco. I am at a loss at the moment.

Thank you.

Mike

Hi Mike,.

There is nothing wrong with your switches or circuit. NEXUS devices have a default COPP on the control plan that limit the size and the amount of traffic that must be the CPU process.

DMVPN and active directory (logon)

Hi all

We have a DMVPN configuration between a few sites and everything seems fine, except that the logons through the VPN for a new domain active directory are very slow (10-15 minutes). I believe that the problem may be with the fragmentation of tunnel and packages such as AD is configured correctly.

I am looking for some recommendations or advice on the MTU and TCP MSS settings see if it solves the problem.

both the hub and the spokes are currently with the following settings MTU and MSS (ive removed some irrelevant information) Tunnel0 was originally a mtu of 1440 but if whatever it is 1400 is even worse.

Thank you

Darren,

In general the prolem is due to Kerberos on UDP traffic.

There are several ways you can solve the problem:

(1) transition to Kerberos over TCP. (suggested)

(2) setting the MSS on the interface of tunnel not on telephone transmitter (recommended)

(3) allowing the PMTUD tunnel (strongly recommended).

The PowerConnect switches do not have the ability to show as much detail as the Force10 can. The RMON tables have an interface use %, what may be the closest we can do on the PowerConnect switch.

#show rmon statistics

I've seen some monitoring software which was able to question the switch via SNMP and get some information of bandwidth. However, this can be a bit inconsistent, according to which switch and what software is used.

The MIBs/OID can be downloaded with the software switch.

Trouble with my MTU settings

I use a WRT54G for online for a xbox360 and computer connectivity. Three days ago my power went out, he came back the same day. Since then, whenever I try to play online with my Xbox 360 it says "MTU test failed" and says my MTU settings are too low.

I tried several ways to solve this problem and none have worked up so I thought I would try here also. I'm always looking for other ways to fix it but if anyone has any useful advice, please report it.

BTW my 360 and the computer are connected to my router, which is connected to my modem is an Arris cable modem.

Follow this, it will surely work...

type in address 192.168.1.20 and give a check mark on the enable box. Click on save settings.

Once you return to the page setup, click the status tab. Take a note of DNS1 and DNS2.

Click Setup... Change the MTU to manual and change the MTU size to 1452... Click Save

Parameters.

Now to assign the ip address given on your xbox
IP address :-192.168.1.20
:-255.255.255.0 subnet mask
default gateway:-192.168.1.1

To set the static IP address on the X - Box go to the network settings on the X - Box... Also assign the dns

address on the xbox in the same way...

Turn off your router and the X - Box... Wait a minute... Turn on the router first... Wait a

Need help to access my MTU settings

, I played Xbox Live for 9 months and have not had any problems with it until my Xbox 360 broke down. I had fixed it so its place and currently under way and I can't use Xbox Live more. I get a message saying my MTU is too low and I need to put at least 1364. I spent some time on this and I ask for all possible assistance. My problem is accessing the MTU settings. I use a WRT160N and I used the web address http://192.168.1.1/ However, when he talks about the box asking username and password I'm stuck. I tried everything, I left as empty user name and the password as an administrator. But it does not work. In other forums, I've seen try the username and the password under the two admin but that did not work or the other. After three attempts, it goes to a red page saying 401 Unauthorized. I disabled my firewall, reset my router and still nothing. If you have a solution to this I'd be very happy!

Thank you!

For the model No, you, there is no username and password is "admin" in the lower case.

The reason why the admin does more work as router password because you have setup a router password, not knowing, in the first time install you your router... If you remember the router password when you used all first your installation CD to install your router then enter this password else you need to reset your router and the re - configure...

To reset the router press and hold the reset button for 30 seconds... Release the reset button... Unplug the power cable from your router, wait 30 seconds and reconnect the power cable... Now re - configure your router...

* Not all the settings above from the computer that is connected to the router.

Right between dell force10 S4810 and S4820

Hello

I have an infrastructure with two force10 S4810 units in battery already and you need to add a new unit to the battery.

As Force10 S4820 switches are in stock, is it possible to setup a stack using these 2 models (S4810 and S4820)?

Sorry, the S4810 can be stacked with other types of system.

My PowerConnect 6248 switch loses its settings when disconnected from the power

Hello

I'll put up a PowerConnect 6248 switch on my local network through Web interface (I can't use serial to do).

I put the IP, login, password, a LAG, SNTP server address, etc.

It works fine until I unplugged the power cord to the switch to simulate a power outage. When I plugged in the power cord, the switch will reboot by displaying its default settings and I release all of mine.

Y at - it a specific command, I missed to save all my settings in the switch?

Thank you for your help.

Pascal.

The switch has two separate configuration locations, a running configuration and startup configuration. This allows you to change configuration and test running before engaging them in the startup configuration. Once you have the running configuration, how you want it, you need to run the # copy running-config startup-config command, or just copy # run start.

See you soon

Hello, Daniel.

Problem solved. It's strange, but all devices have started working after restart 8132 switches. :)

PowerConnect 6200 series interoperability with 3Com Switch 5500.

Hi all

We offer to our customer Dell PowerConnect 6224 and 6248 as they are expanding their network.

Their existing network is 3Com Switch 5500 and the main switch is 5500G - EI. Of course, on their network, they have mutiple VLAN and switch 5500G - EI core will make the VIRTUAL LAN routing.

I would like to know, is it questions about interoperability between 3Com Switch 5500 and Dell PowerConnect 6200 Series, especially on the VLAN routing?

Know your opinion.

Thank you and best regards,

Syed.

I'm not aware of any questions that you would see with the use of these switches together. On switches 62xx you set them VLAN, and then set the connection of 3Com in general or Trunk mode, allowing the VLANS on the connection.

Create a VLAN

Console (config) # vlan database

VLAN console(config-VLAN) # 2

VLAN console(config-VLAN) # 3

VLAN console(config-VLAN) # 4

output console(config-VLAN) #.

Configure the interface in Trunk mode and allow for VLAN through it.

console switchport mode trunk #.

console # permit trunk switchport vlan add 2,3,4 tag

You may need to set a static route on the 62xx switch so the traffic on the next hop.

Console (config) # ip route 172.16.0.0 255.255.0.0 10.0.0.2

Here are a few good white papers to look over. Not all of them concern the 62xx switch, but the information is always good.

ESXi 5 dvswitch and MTU settings

Edit: I'll post the config info here for anyone else looking for a quick "How To". It's super simple but not obvious.
After you add a host to the DVSwitch, navigate to Configuration, Networking, vSphere Distributed Switch, manage virtual cards.
Here you can add virtual NICs that you can set the MTU value for each of your groups of port. Hope this helps someone else.
I have a question about MTU settings.
In my scenerio I only have 1 2 port 10gig card at my host. I have every port as a dvuplink to separate switches.
My question is, when you set the MAX 9000 MTU to support frames for ISCSI dvPortGroups, do all your other traffic in VM network exchanges 9000 thus, change d ' assign my stand alone equipment is 10/100/1000 MTU 1500.
so I guess what I'm wondering really is,
a guest virtual OS/machine running on this dvswitch in a dvportgroup, MTU is always maybe 1500? While he could talk to hold single device on the fabric.
I know to support ISCSI frames and must be supported from BEGINNING to END, mine is esxi to switch to the san.
so I just need a dvswitch dedicated for MTU 9000 and a dvswitch dedicated for MTU 1500 or 1500 traffic cannot exist in the 9000 switch?
I'm relatively new to the frames, so I will try to figure out how my design "should" be.
I do not have the budget to add more 10gig network adapters on each host. I know that sounds bad but that is where we are. It would be just a waste of flow... I just don't need that much flow. 2 uplinks of 10gig already more than meet are needs.
I have attached a presentation of how visio I wanted to put this out, but once I started to think through MTU, I was like uh... which will not work, it will be?

Allowing a large MTU on the dvswitch will not do damage to your virtual machines. It is easy to get confused about this, but the MTU setting on the switch, it's just that it will allow the biggest executives to 1518 bytes. The MTU size changed the switch will be invisible to your virtual machines and they will continue to use default MTU 1500 without problems.

In other words, you can have with 9000 VMkernel iSCSI adapters and virtual machines with 1500 on the same dvswitch.
