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?

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.
HTH,

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

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.

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.

Package marking verification of outgoing packets for Immersive Endpoints TX, series CTS
Hello
Y at - there no way how to check the marking of package out of TX systems and immersive of CTS on the system itself please?
I can find it somewhere in the newspapers? In which we please?
I can see packet marking for incoming packets in the statistics of appeal, but not for outgoing packets.
CUCM config is EF for voice and AF41 for video (verified in the telephony settings), but I can see the audio and video packets on another site like AF41.
Really appreciated any answer.
Kind regards

As Chris has said, use something with port mirroring to be sure.
There is also a cpapability of capture on the CTS / systemes systems of TX, please see the guide to the cli

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.

ACL to prevent gnutela, outgoing kazaa, grokster traffic
Hello
I have a client who has a 3640 router edge style. It is an educational institution, the network administrator has really no students mind pulling the music down, he won't simply foreign guests pulling music out of the boxes, studying its network.
I want to build on this 3640 access lists to prevent outbound connections for these music services...
Inside the network numbers are 192.240.88.0 for example...
pls help...
It relly is dependent on your music file sharing protocol. For example, to configure an access list to block KazaA, access list statement would be something like
access-list on refuse tcp host x.x.x.x any eq 1214
ip access list allow a whole
Here's more information you might help you. Some of this information is old and it might not be applicable. It would be wise to cross-check the same.
App: Kazaa and Morpheus
Block customers who connect with each other and the application is broken.
-Deny TCP and UDP 1214
App: WinMX
This package is Napster-like and requires a central site to allow file sharing. This site by its IP blocking prevents its use.
App: AudioGalaxy Satellite
This package uses the top ports to find servers AudioGalaxy Satellite and FTP (TCP 21 and 20 TCP) to perform the actual file transfers. Also block the AudioGalaxy network block should help. Denying completely FTP will prevent this service as well.
-Deny TCP and UDP TCP 41000-42000
App: Napigator
Napster as a tool, requires a central site to function. By blocking the central site of blocks Napigator.
App: Freenet
The only effective way to catch this kind of traffic is to watch traffic heading for the witnesses. Many PacketFilters allow research the first packet of a flow for the matches in the string. In General, the implementation of this type of filter is outside the scope of a simple how-to doc. The Protocol is built from the groundup to not rely on a specific port. For more information, refer to
App: Napster
Block access to the Central netblocks of Napster (these may change from time to time) that prevent the use of Napster:
-Refuse any traffic and traffic to source.
Block access to peer file sharing, filter only the default ports. This may break some (very dubious) internet use but would prevent his use of Napster if the network block above should change to another set of addresses.
-Deny traffic to destination: 0.0.0.0/0 TCP 6699
-Deny traffic from source: 0.0.0.0/0 TCP 6699
-Deny traffic to destination: 6699 UDP 0.0.0.0/0
-Deny traffic from source: 6699 UDP 0.0.0.0/0
App: Aimster
Blocking Aimster requires blocking AOL Instant Messenger (AIM). GOAL becomes harder to block without the use of a filter or a proxy that examines the TCP 80 (Web) traffic and check that in fact only HTTP traffic is passing on this port. Using the following filters do AIM (and Aimster) much more difficult to use.
Block ICQ/AIM client traffic
-Deny traffic to destination: 5190 TCP 0.0.0.0/0
-Deny traffic from source: 5190 TCP 0.0.0.0/0
-Deny traffic to destination: 5190 UDP 0.0.0.0/0
-Deny traffic from source: 5190 UDP 0.0.0.0/0
Given that the OBJECTIVE can also use TCP 13, 23, 80, 113 and others, it might be preferable to blocklist AOL sites altogether or only allow DNS lookups. This break solution good enough access to AOL from use with care. The best solution is described above, filter 5190 TCP and UDP 5190 but also use of filters or proxies that do not allow non-HTTP traffic using TCP 80.
App: iMesh
Blocking access to the central server iMesh breaks iMesh.
App: eDonkey
Customers to block the connection to the server
-Deny traffic to destination: 0.0.0.0/0 TCP 4661
-Deny traffic from source: 0.0.0.0/0 TCP 4661
-Deny traffic to destination: 4665 UDP 0.0.0.0/0
-Deny traffic from source: 4665 UDP 0.0.0.0/0
Block customers who connect with each other
-Deny traffic to destination: 4662 TCP 0.0.0.0/0
-Deny traffic from source: 4662 TCP 0.0.0.0/0
App: Gnutella (BearShare, Limewire, ToadNode, Gnucleus and other)
When left with the default settings, Gnutella can be blocked as follows.
Block customers who connect with each other
-Deny traffic to destination: 0.0.0.0/0 TCP 6345-6349
-Deny traffic from source: 0.0.0.0/0 TCP 6345-6349

Preventing the merger of spans
Hello
I have a question on how to prevent a particular time have merged with adjacent. I saw something posted somewhere just now mentioned something to the subject because the definition of the property 'id' on a FlowElement element will prevent that element being merged with others. If I assign an id to a span, which will prevent it from ongoing merger with any adjacent spans that have identical text layout formats? Assign a unique user style do this also?
TIA,
Brent
So that the two spans of merge, their attributes must match, and this includes the ID and attributes defined by the user that have been applied. So if the two spans have the same attribute defined by the user, but with different values, they will not merge. If a span has the attribute defined by the user and the other is not, they will not merge. The game must be complete for the merge to happen. Or if the two spans have different values for the 'id', they will not merge.
Thank you

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.

Whenever ESXi is powered on, a switch of gigabyte or a FastEthernet switch... I have drop packet. Take a look at the picture so see what I mean.
Here's the scenario:
Cable Modem - > 2821 Gi0/0 - > 3550 Gi0/0 - Port-Channel 1
-Gi0/2 and Gi0/3-> ESXi Server (with IP hash)
-> host: DNS/DHCP Win2008 Vlan 40
-> VMkernel: 10.10.80.5
Before being on a purchase order, the ESXi server was plugged into a regular trunk port.
If I use a laptop computer plugged into a port on the switch... I get an IP address and the DNS works well.
HERE'S THE PROBLEM:
I have NO IDEA why she did this. The iOS are more recent. The server is updated to the latest version. WinServ2008/DNS/DHCP uses a network card VMnet3 and not E1000.
ESXi is 5.5.
I did the configuration of VMware with this tutorial:
ANOTHER FACT: when the port Gi0/2 and Gi 0/3 are closed, no more problems.
The router config and Switch is below.
Can someone help me?

---------------------------------PROBLEM SOLVED!
I can't find the article, but he was right. In this article, they said that the decline of the package could be the cause of the Vkernel interface in the same vswitch as virtual machines.
So I vmnic1, configured as a switchport access vlan 80.
Then, I changed the ip address of the interface vlan 255.255.255.252 80 to 10.10.80.6.
(my vcenter server is already set up to the communication of the esxi via 10.10.80.5).
Here is the final result that now works. MORE NO PACKET DROP.
Thank you all!
