• Reference Dell Spanning Tree PowerConnect 2748

  I had just a simple question on Spanning Tree. We have a network configuration and everything is already difficult to implement the tree covering weight on the powerconnect switches if you already have your network configuration is? is it a day all? A lot of configuration? Or just a simple turn on button?

  Sorry, the PowerConnect 27xx switches of the series DO NOT switch support the STP (Spanning Tree) Protocol.

• SGE2010 switches, VLAN and a port blocked by spanning tree

  People,

  I have 2 groups of switch.

  SGE2010 2 with VLANS is defined as 10,20 and 30

  VLAN 10 is the management VLAN and it uplinks to our border router.

  VLAN 20 is the workstation VLAN, and all workstations are pointing to the switch as their default GW

  VLAN 30 is the ip phone VLANS, and all phones use this as a gateway.

  I have a GAP between the switches said, we have a few servers on the ip phone switch that must be accessed by the clients of the workstation and the unique link of 100 MB through the router probably won't be enough.

  If I understand correctly, because the switches have different networks on them, a simple shift will not work. I did create a gap and addresses on each side, but it does not appear in this mode, I can block vlan 10 transit to the LAG, with this block I'll end with a logic loop and spanning tree will block the uplinks or LAG itself.

  I have attached a picture with a diagram of our current put in place.

  Any help/advice would be much appreciated.

  John, the 802 standard. 1 initial q indicates there isn't only global tree covering weight independently of belonging to a vlan. It's why you run into problems. Cisco has developed PVST to run on circuits of the ISL. BPMH was originally defined as 802. 1s, which is a combination of 802. 1 q + RSTP. The 802. 1s were later modified to become part of the 802. 1 q.

  The person is incorrect, because they cite "because spanning tree is construction by vlan. They are incorrect, because you have to set the properties of tree cover to allow the spanning tree protocols by vlan. Small business switches do not support the owner Cisco PVST and PVST +. However, the SB switches support BPMH which is a standard of the IEEE.

  How works the BPMH, it's that you have called proceeding, i.e. each construction covering tree. Then you have the region, SB switches support only 1 region. The region maintains the instances. Basically how it works, you activate the EMU at the global level. Then, you specify the instance. As an example, the vlan 1 is instance 1. VLAN 2 is 2.  This will allow you to run 2 physical wires between switches vlan different without looping. If you use classic STP or RSTP, the least costly path will go to the State to block/cast who works as expected.

• Is the spanning tree bpdu filtering on the 5548 "bpdufilter default spanning-tree portfast'

  It seems to me as "the protocols spanning-tree bpdu filtering" on the 5548 the same "spanning-tree portfast default bpdufilter" on the switches of the series N - is that correct?  If this is not the case, what is the equivalent command to 'spanning-tree portfast default bpdufilter?

  Ken

  They lead to the same result, just with a little different method. N-series bpdufilter search all ports configured for portfast and disables the transmission and reception of BPDUS on these interfaces. With the looks of 5548 bpdufiltering for ports with covering weight tree disabled. There is not a command on the 5548 that will search interfaces in portfast mode and filter the BPDU.

• Prevent advertising outgoing packets Spanning tree

  Hello

  I have a switch 2960 with a workstation that is connected.

  The switchport is configured for the portfast and the BPDUguard is enabled on the default switch

  When I have wireshark information on the connected pc then I see a lot of STP packets from the switch.

  I would like to disable these messages because the information located in the capture packets can be abused by an attacker who has access to this workstation, for the configuration of protocols spanning-tree of the company information.

  Is it possible to disable the spanning tree information that is sent from the switch?

  concerning

  Jan

  You should be able to configure bpdufilter to stop it. The only problem is that effectively stop you stp on this port, which could be dangerous.

  Understanding of the functioning of PortFast BPDU filtering

  BPDU filtering allows to avoid transmitting BPDUS on active PortFast ports that are connected to an end system.  When you enable PortFast on the switch, protocols spanning tree ports place in State shipping immediately, instead of going through the listening and learning States of transfer.

  By default, the tree covering weight sends BPDUS of all ports PortFast is only enabled or not. BDPU filtering is on a per-switch basis; After you enable BPDU filtering, it applies to all active ports PortFast on the switch.

• How can I configure Spanning Tree

  Hello

  I have several core Dell passes using PowerConnect 6224 s most - these ink in my Cisco provider kit. We run several VLAN and have redundant links between stacked switches.

  I have read up on top of the tree covering weight and have the following tasks:

  1 map of the network - including the ID of the root bridge, root ports, roads blocked, age max and time of helo

  Once I made my analysis information, I don't know how to better optimize the covering tree config, so far I have:

  1. make sure RSTP is enabled on all switches
  2. make sure that all edge ports have spanning port configured fast shaft
  3. not declare spanning port fast shaft on the links between switches
  4 force speed and duplex settings on all ports to link between the switches (I guess that's because the auto negotiate takes more time?)

  I'm not sure is:
  1 can I use BPDU guard and if so, where?
  2 can I use root guard and if so, where?

  I read the informative article by Todd: http://en.community.dell.com/support-forums/network-switches/f/866/t/19465205.aspx

  But, I don't know where\whether I should to configure the options of guard - am happy to provide additional information as needed.

  Thank you

  Spanning Tree BPDU Guard is used to disable the port where a new device tries to enter the already

  existing STP topology. Thus the devices, which were originally not part of STP, are not allowed to

  influence the STP topology. If the Enable value, when a BPDU is received on a port of the tip, this port is disabled. Once the port has been disabled it requires manual intervention to be reactivated.

  Spanning Tree Root Guard is used to prevent change of the root of a Spanning Tree instance

  in an unexpected way. The priority of an ID of adjustable bridge to zero but another bridge with a low mac ID

  address could also set its priority to zero and take root.

  Both are defined globally on the switch. If you have any possibility of other network devices being plugged into the switch without your knowledge. It may be a good idea to these permits after that STP is configured on the network. That way if someone randomly connected network with STP on this device, it will not throw your network for a loop.

  Here are some good white pages on the tree covering weight

• Spanning tree of routing bridge

  Good day to all

  I have a problem in my network with an old device with a 10mbit half duplex nic - we have switches Powerconnect N3048 in basket - we found that they don't play well with the old device, so we added a 1000/100 old switch to do the translation so to speak.

  The problem now is that STP has not been configured in time and the older switch has taken the role of routing bridge.

  My question is - if I have now set up the N3048 be the bridge on the road, I'll be able to do without affecting the production network traffic, or do I need to down the network to make the change?  Will be the change of the switch N3048 force older to cede control, or they will fight?

  Thanks in advance

  Eric

  By default most of the switches will have a default priority of 32768. In this case, the switches, then use to determine MAC address which is the root device. If this is the case in this scenario, all you have to do is set a less important priority tree covering the desired root switch.

  On your central switch, issue the following command:

  console (config) #spanning 4096 tree priority

  This switch will become the root switch. Should not all switches to be restarted, but will cause a topology of notifications of changes throughout the network, and some ports may change their current status. It depends on the topology.

  I could do this during non peak hours. May also want to check the switch that you added to the network and make sure that it doesn't have a priority tree covering of 4096. If this is the case, set it to something higher.

• Spanning tree Distribution Switch Port is root for all the VLANS

  Hello world.

  Uplink to switch on 2 layer network flat if Distribution change a.

  This distribution uplink port is Root Port.

  Core switch port goes to the Distribution switch appears as State PLEASE FWD.

  It will cause slow for users who are connected to the network on the Distribution switch?

  According to my understanding core should be Root STP for all the right of VLAN?

  If necessary how can I make kernel as root port switch port?

  Thank you

  MAhesh

  Hello

  a root is a designated port (if shipping port) on a non-root bridgewhich a path root the lowest cost to the root bridge. So there is nothing unusual here, and your kernel needs to be done to root bridge if you run STP between distribution and kernel as you apparently.

  Kind regards.

• Change STP UME in RSTP mode on two stacked powerconnect 6224 configured for iSCSI during normal operation

  Hello

  I'll do a fw upgrade during normal operation on a stack of 6224 circulating BPMH, I am currently aware of recommendations Dells run RSTP on switches configured for iSCSI traffic connected to Equallogic SAN.

  I intend to set up another pile with two 6224 to failover and then perform the upgrade on the stack of "old." My question is if it's possible to run BPMH on the 'old' stack RSTP executing on the new stack when LAG is configured between the two batteries?

  Another option would be if it is possible to reconfigure the 'old' UME to RSTP stack without interruption between the hosts and the SAN first?

  Guidance on this subject would be greatly appreciated

  Cree

  Multiple Spanning Tree Protocol is based on RSTP and is backward compatible with

  RSTP and STP. So, you should be able to run BPMH on the old and RSTP on the new.

• Port of uplink on PowerConnect 8024F went to the D State down

  We had a strange behavior on one of our switches PowerConnect 8024F. The uplink port of the device (connected to a port on a Cisco Catalyst 6513 10Gig) came down. The output of 'show interfaces status' looked like this:

  .. and so on. Firmware is 5.1.2.3. We rebooted the device and he returned to normal behavior.

  It's all associated spanning-tree protocols. D to the bottom is synonymous with diagnostic downwards, which occurs if more than 15 BPDU per second is received during 3 seconds. The switch closes the port. USL worker task is bound traffic so a big change covering tree cause it's really high.

  Yes the packets can be lost during covering the election of the tree. If the status of the auxiliary port is bouncing between two ports, packages to send can be lost. If you want to try to leave it this way and still have 1 port throw, you can try to change the port on the ports 1 priority so that it is more likely to be the port to be scrapped.

  The following example configures a port to be less likely to be selected for transfer to the root bridge, even if the host starts sending of BPDUS.
