• Port Mirroring mit SRW2016

  Liebe Foren-user,

  ICH möchte like einen Port Switch SRW2016 "monitors" (second later mirror-Port). Dazu habe ich einen Rechner mit und tcpdump aufgesetzt, diesen a debian Port einen angeschlossen (den probe-Port). As soon as ich über das Web Interface Linksys-switches switch unter meines-> Port Mirroring den mirror-Port auf den spiegeln tired (both Directions) Port probe, ist tot practical der probe-Port. ICH kann vom Debian-Rechner aus nichts mehr pingen (auch nicht den Linksys Switch), er kriegt keinen release DCHP mehr und er ist auch nicht mehr aus dem Netzwerk reached normal. Konnte damit ich ja notfalls leben, however scheint überhaupt kein mehr auf dem probe-Port anzukommen traffic. Tcpdump shows mir keinen traffic one.

  Mache ich irgendwas please? Sind die Einstellmoglichkeiten zum Port-Mirroring am State ja, ich SOMIT fits Linksys, actually nicht viel outlined machen zu können. Equivalent Passagen im hab ich naturally read manual.

  Vielen Dank und Grüße

  Von your description wird nicht klar, wie das MIrroring exakt adjusted did.

  Der 'Source' Port is the Port the system want to play, wo der d.h. den "Original"-Verkehr drüber geht. "."

  Der 'Target' Port is the Port, auf die in den packages kopiert werden, d.h. sleeps schliesst tcpdump mit den of the computer one.

  Buyed is, dass die Netzwerkkarte am target Port both adjusted ist, dass sie alle frames akzeptiert. Frames usually werden ja alle, die nicht die loading MAC address verworfen haben.

  Also hat computer der über den Port target keine connection. Target akzeptiert keine der-Port frames. ER sendet nur die copies of the Source Ports. Das ist eine der SRWs Beschrankung banknotes.

• PowerConnect 7048 Port Mirroring

  Hello everyone,

  I'm trying to mirror two ports on my 7048 Powerconnect switch. One of them is a Trunk Port, and the other is just a port not marked. I don't see any incoming traffic on port of destination. Is it possible a bug in the Web management interface, which does not apply this correctly?

  Current firmware 4.2.2.3

  Thank you

  David

  We can try to activate the admin mode. I couldn't find the command to do this, but in the GUI there is a drop down under the switch > ports > traffic mirror > port mirroring. Allowing and see if the behavior changes.

  I am also curious to see of any change in behavior after an update of the firmware.

  Thank you

• Port mirroring for the uplink of 10 GB of PowerConnect 6224

  I need to take a copy of the traffic over a 10G fiber link. The amount of traffic on this link is less than 1 Gbps.

  I am considering using the mirror port on a PowerConnect 6224 for this function. However, I don't know if port mirroring also works on the links to the top of the switch.

  Anyone know if a port 10G uplink on the 6224 can be mirrored on one of the 24 Gigabit Ethernet ports?

  I've been the mirror of able port of a fibre port with an Ethernet port, following the instructions on page 333 of the owner's manual.

  http://support.Dell.com/support/eDOCS/network/PC62xx/en/UCG/ucg_en.PDF

  He took it and did not return any errors. But I see potential for some issues if the fiber port went above 1 Gbps.

  

  Keep us updated and let us know what are your conclusions.

  Thank you.

• SRW2048 port mirroring

  Hello

  Does anyone know the specs on port mirroring feature for Cisco SRW2048 48 - Port Gigabit Switch?

  I need to know:

  1.-y there a limit to the port mirroring sessions?

  2 - a target port can receive traffic from multiple ports?

  Hello Alejandro,

  This switch supports only 1 session - i.e. the 1 target mirror port. SRW and EMS/EMS switches can have up to 8 ports source while SLM switches can have up to 4 ports from source. In any case, there is only one target mirror port.

  Thank you

• Configuration of MXL port for PS-M4110 storage array

  Dear all,

  I have to configure my Force10 MXL GbE 10/40 for PS-M4110 storage array. I have two PS-M4110 connected to ports 0/13 and 0/15. I have configured the following way.

  FTOS (conf) # don't activate any dcb

  FTOS (conf) # enable iscsi

   

  Configuring the ports 0/13 and 0/15 (ditto)

  OTF (conf-if-you-0/15) con #sho
  !
  interface TenGigabitEthernet 0/13
  no ip address
  MTU 12000

  switchport
  FlowControl rx tx off
  spanning tree bpmh edge-port
  spanning tree rstp edge port
  spanning tree portfast 0
  spanning tree pvst edge-port
  Profile-compellent iSCSI

  I just need to know if these settings are correct. And what I have to configure iscsi target (3 260 860) ip address of the port-(A.B.C.D) as well? If Yes, then what IP should be given here? Group-IPaddress?

  I used this guide as a reference.

  http://Dell.to/1uxp4LW

  And it seems that you have everything in place. The guide recommends not to use iscsi optimization for large san deployments. You can browse the guide too, just to double check.

• A group of link aggregated traffic mirroring

  Hello. I would like to mirror traffic entry and exit of a group of aggregation of link on my Dell PowerConnect 7024. By looking at the http under switching configuration page > Ports > traffic Mirroring > Port Mirroring > add, it doesn't seem to be an option for traffic a single port and not a link aggregated mirror group.

  Can someone help me to check if this is doable? If so, how?

  Your results are correct. Associate connection ports are not able to participate in the port mirroring.

• OnPlus MY port LED not always turned on/active when connected

  I noticed that the port of LUN is not still active despite being connected.

  The port will go completely dead where even a powercycle of the ON100 will not activate the port (eth1 on the device I believe based on of NTOP poster config).  The switch (SLM2008 - v2.0.0.10) show that no device is connected and by moving the ON100 on one another well known port will always appear also died.  Sometimes to put the ports will cause the next LUN interface to life, but not always.

  When it works I have no problem using the mirroring port SLM2008 had with NTOP for obtaining all the expected data however I can't quite trust this configuration yet due to the interface of MY not being always active.

  Suggestions?

  Other than that and a few strange bugs listed in May the release notes I hit, I'm really loving this service despite the lack of support from RV220W (I hope it's in the works of Cisco / the TeamF1 show the).

  Michael - I assume that you have already tried to replace the cable also?

• SPAN and SIP Trunk recording in parallel

  I'm looking to get away using a dictaphone SPAN and use SIP automatic trunk of the record (by using a recorder DMS Verint pool UDP) calls.

  My question is, if I apply SIP trunk recording simultaneously with recording SPAN, this mind? I need to make a CEP of the solution, but cannot stop the current recording.

  Thanks for any help you can give me!

  With the traditional port SPAN record in the Callmanager ignores the phone is registered, so when you activate the current record there will be no impact.

  However you can finish by double flow at the end of voice recording, so not sure what verint would do that.

• SPAN and TCP RST

  I know that a Cisco IDS allows to inject a TCP RST in a SPAN port in order to kill a connection.

  My question is: this technique works only when you switch ports SPANing, or will it also work when SPANing VLAN? I was told that is not possible. Suppose a 6000 series switch.

  Regards, Jeff

  Some switches allow you to send TCP reset via the Span port and some do not. TCP resets through the port Span are therefore very switch to load, and you can read your documentation of switches. (Not all Cisco switches has exactly the same).

  IF the switch allows TCP resets the Span port then the resets should work for port and Vlan Span sessions with a few warnings that you can read below.

  IF the switch does not TCP resets the Span port, then TCP resets do not work whatever the Span session type you have.

  In a Session of Span Port, the port being calibrated must be in the same vlan that is configured for the destination span for TCP port resets to recover the vlan good work.

  If you try to Port Span ports of different VLAN, then the sensor will alarm OK, but the TCP reset works only on attacks that are visible on the same vlan assigned to the destination span port.

  VLAN spans have the same limitations. If you cover a single virtual LAN vlan is attributed to the destination span port, then the TCP resets will get to the vlan right and should work.

  If extend you from several VLANs and then the TCP resets will only work on the same vlan assigned to the destination span port.

• Port security and DHCP

  Hi all.

  I have configured the port security in some ports, and I don't think it handles images as it should. the following settings are

  -max: adds the correct number of MAC

  -permanent safe mode

  -throw

  I connect the legitimate devices to determine the maximum number of MACs, the port must learn and then I connect a device with Mac unsafe. I can get an IP address from the DHCP server, but no traffic is being so forward. I think that no legitimate unit should not be able to get an IP address as port security ignores all frames with an unknown source Mac

  Hi Stelios,

  Your configuration seems to be fine. Mine was connected only with the safety of ports and addresses max I put at 1. I see only 1 MAC address sends bootp all other devices connect via the switch on this port send no bootp.

  You could also make the capture of packets using the capabilities mirror port switch and application of wireshark. Devices are perhaps using old known IP addresses...

  Kind regards

• The ACP prevention policy and intrusion

  Hi all

  What happened to apply a strategy of access control with some rules and some Intrusion prevention policy in an architecture where the ips is deployed in passive mode with a mirror port?

  Is it advisable?

  Thanks in advance

  Lore

  Hi Lore,

  Deployment of the IPS in passive mode is quite common, but it has its own deployment limits (see below).

  Usually, in a deployment passive IPS, firepower system monitors traffic circulating on a network using a switch, SPAN or mirror port. The SPAN port or mirror allows for traffic to be copied to other ports of the switch. This provides the visibility of the system within the network without being in the flow of network traffic.

  Please keep in mind, when it is configured in a passive deployment, the system cannot take certain actions such as blocking or traffic shaping. Passive interfaces receive all traffic without condition, and no traffic received on these interfaces is broadcast.

  Some other info and configuration:

• Use of Internet reporting real-time bandwidth

  Need advice with regard to the selection of software and the physical layout. I was invited to present reports on the use of the internet;

  -IP address

  port/protocol

  -bandwidth

  We havcusco cisco 4500.

  Our ISP router's router 3400 metro (fiber to Ethernet media converter).

  We have the ISP that is connected to a port on the 4500 in vlan 99, users are in vlan (using a gateway to virtual layer 3) 44.

  If I want to make just a quick capture could I just simply connect a workstation with wireshark to a port on the 4500 and place this port in vlan 99?

  If so I guess that the same theory would work with the tool as bandwidthD which is best suited to long term capture and has a nice pretty GUI for my manager?

  Bit confused as to whether I need a mirror or span port configuration.

  Thank you

  You need to configure SPAN with VLAN 99 as a source and the port that your workstation in question is connected to the destination. Otherwise most of the traffic will never reach the workstation considered.

• Grouping of NETWORK cards causing the ESXi to retransmit ethernet frames received.

  I had an HP Proliant DL380 G5 ESXi 5.1.0 connected to a Cisco 3750 Switch stack.

  All by performing a tcpdump on a host without a report, I discovered that he was under the bombardment with ethernet frames for the MAC address of a computer virtual located on a host across the data center. After a few brief troubleshooting, I discovered that I was able to stop those erroneous frames by disabling NETWORK adapters on my VMWare host group.
  
  I believe that in my situation when ESXi is configured to use two network cards to all frames received on vmnic0 and retransmits them on vmnic1 and vice-vesa. I experienced these symptoms when ESXi is configured for failover with an active adapter and adapter mode standby and I also experienced the same symptoms in the following load balancing configuration.
  

  
  

  Symptoms: some time after activating the load balancing, all frames Ethernet for the MAC address of a virtual computer on the affected host are broadcast on each switch port in the entire data center.
  
  Steps to reproduce:
  (1) implementation below configuration.
  (2) unplug the ethernet cable connecting vmnic1 and switch1 port gi2/0/4
  (3) run the host 1.1.1.1 EI - n - q tcpdump on any machine physics linux in the data center (don't even have to be connected directly to 1).
  Confirm there is no packet seen with the IP address of 1.1.1.1 destination
  (4) plug the cable between vmnic1 and switch1 gi2/0/4 port ethernet
  (5) wait 60 to 120 seconds
  (6) watch a burst of frames ethernet with the destination MAC address of the VM (which owns 1.1.1.1) in the output of tcpdump

  I apologize for the delay in my response.

  Unplug physically 2 cable NETWORK card on the host and configuration mirrored port on the switchport to 1 NETWORK adapter of the host, I have been able to confirm that the host VMWare issues guides on NIC1 with a destination MAC address of one of its own VM.

  After carefully reviewing the captured data, I noticed that the destination frames wrong "02:bf:cb:50:a2:76" MAC address actually belonged to "Local Area Connection 1' one of my Windows 2003 Server WHAT VM installed on the suspected host.

  Dig a little deeper, I discovered that this virtual NETWORK card is presented to the operating system as
  Name: Local 1 network connection
  "Type: VMware Accelerated AMD PCNet adapt."
  MAC: 02-BF-CB-50-A2-76

  But the configuration of the virtual machine in vCentre is
  Name: Network adapter 1
  Type: Flexible
  MAC: 00: 0C: 29:fa:e8:83

  Note the different MAC addresses.

  Digging a little further I discovered that Windows 2003 server has configured on "Local 1 network connection" network load balancing and NLB is the cause of the altered MAC address.

  Rather than to investigate further I have just placed a load balancer linux before the server windows 2003 cluster and that you turn off NLB.

  But I suspect that there is still a fundamental problem in the Virtual Switch VMware with how he learns the MAC addresses of the virtual machine is using flexible vNIC. In particular, with a virtual machine that uses a form to override the MAC address such as that used by NLB.

• BitLocker network unlock

  I'm trying to deploy BitLocker network unlock, but I have problems when the computer tries to get the certificate of the WDS server (different from DHCP as Microsoft tutorial explains). Monitoring by Wireshark start-up (with mirror port switch), the computer gets a valid IP address, but pray the Bitlocker PIN (failure). Looking at the event log, the message "Bootmgr not got the protector key network. BitLocker volume master key" message. I tried to look on the Microsoft Web site, but have no information of what can be, computers use Win 10 as operating system and Windows Server 2012 r2 servers. Could someone help me?

  I followed this tutorial (https://technet.microsoft.com/en-GB/library/jj574173.aspx) to set up.
