• Why IPSec does not support multicast traffic?

  If IPSec is a tunnel, why can't set you the multicast traffic in an ACL to protect?

  IPSec is a standard, and there is nothing in the standard that allows for multicast or broadcast traffic to go through it.

  Specifically, the IPSec RFC (ftp://ftp.isi.edu/in-notes/rfc2401.txt) says things like:

  A security association is identified by a triple compound

  a security parameter Index (SPI), Destination IP address, and a

  identifier (AH or ESP) security protocol. In principle, the

  Destination address may be a unicast, broadcast IP address

  address or multicast group address. However, the IPsec Security Association Management

  Currently, the mechanisms are defined only for unicast SAs.

  and

  The receiver-orientation of the Security Association implies that, in

  the case of unicast traffic, the destination system will normally be

  Select the SPI value. Making the destination select the SPI

  value, there is no risk for manually configured security

  Associations to conflict with automatically configured (e.g., via a)

  The key management protocol security associations) or safety

  Associations from several sources in conflict between them. For

  multicast traffic, there are multiple destination systems by

  Multicast group. If some system or person will need to coordinate

  Among all the multicast groups to select an SPI or SPIs on behalf of each

  multicast group and communicate the IPsec group information to

  all legitimate members of this group of multicast through mechanisms

  not defined here.

  Several transmitters to a multicast group SHOULD use a single title

  Association (and therefore Security Parameter Index) for all traffic to

  This group when a symmetric key encryption or authentication

  algorithm is used. In such circumstances, the receiver knows only

  that the message is from a system with the key for this

  Multicast group. In such circumstances, a receiver will be generally

  not be able to authenticate which system sent the multicast traffic.

  Specifications for other, more general multicast cases are postponed

  for later IPsec documents.

  Sorry to quote RFC from you, but we just follow the standard and the standard does not support this. You can bypass it by setting a GRE/IPSec connection, but what really is encapsulating the broadcast/multicast in a package of volition unicast first, then encrypt this unicast packet.

• How to restrict multicast traffic to specific ports on GS716Tv3?

  I can not find specific instructions to limit traffic of multicast on the smart switch GS715Tv3.

  I need to force all multicast traffic to travel on a specific set of interfaces, or at least stay within a given virtual LAN on the switch to which it is native. All the changes you want multicast servers and listeners will be on these interfaces in their separate vLAN.

  We have several GS715Tv3 switches configured identically, but multicast traffic does not pass between the switches.

  Topology:

  Eight GS716Tv3 smart switches, each configured with three VLANS identical.

  No traffic should pass between these VLANS on the switch or pass between the switches

  In other words, even if all the 8 switches each have a vLAN named "IOSubsystem", I do not considered the same vLAN.

  .

  vLAN 4 is corresponding to the hosts of Linux to address major

  vLAN 5 is for the audio subsystem

  vLAN 6 is for the IO subsystem

  VLAN each switch 4 has two active ports, a session to the external interface of the main Linux host and the other to a central switch of 9th GS716Tv3 where a system of software development is also linked.

  VLAN each 5 switch connects to the components of the audio subsystems (not shown).

  VLAN each switch 6 has two active ports, a going inward a lead Linux host interface and one for the IO subsystem.

  We get multicast traffic unwanted between each of these systems, causing corruption of our stream. We limit the multicast traffic on vLAN6 of each switch to stay on the vLAN6 of this specific switch.

  Thanks for any help.

  To switch the management VLAN to 4.

  Make sure you have 2-way switch, one in VLAN4 in a VLAN1.

  4 and apply the value of the system you use to a static IP address to the switch and confirm the access to the web configuration and then change "management VLAN ID. then pass the system that you use on the port or any VLAN 4, then you should have access, otherwise, wait about 60-90sec and try again, because you might have PLEASE and it will block anything on the port for just under its set to "Enabled" 'Fast Link '.

  Then under "IP Configuration" value switches other IP address in IP range of VLAN4.

  For the love of Simplisicty, unmarked ports should never be in 1 VLAN simultaneously.

  And instead of using the point and click, goto "Port PVID Configuration" and just create the VLAN it.

  Member of the PVID and VLAN the same thing for a port, on what VLAN, it must be in the database

  And to confirm, you have a cable from switch to each VLAN? You can cut down on cables and ports if you tag/trunk ports to the next switch. then all VLAN 3 just 1 cable between each pair of switches, saving you at least 4 ports on each switch.

  Just an example of my GS724T (ignore ports g8 and g-19-20, their current PVID is because of something else you do not, LACP and Span/Monitoring):

  All ports are configured to a single VLAN, my 'LAN hand' is VLAN12, that the management VLAN is set for, g23-24 ports VLAN trunks, they are set on tagg VLAN12 and 14 when the traffic is out of these ports, then switch to the other side reads the consequence tagg and acts, that way I don't need 2 cables/port for each of them.

  

• Multicast flooding all the VLAN Ports

  I have three streaming servers.  We have an affair rising gigabit and the other two 100Mbps devices.  Gigabit streaming chassis produced ~ 230Mbps video stream. The other two 100 Mbps devices generate on 50Mbps each.  All water courses are intended to let the N1548 switch via a 10GE interface.  It works, but video streams multicast are also fed to all other ports on the same VLAN.  For this reason, + 200 Mbps gigabit traffic unit is saturating the other two aircraft video 100Mbps of FastEthernet NIC.  I tried to put all the ports in a single protected switchport group, but this did not seem to prevent floods multicast to peer between ports assigned to the same protection group number.  Is there a way to prevent this multicast traffic to broadcast to all ports in the same VLAN, specifically servers independent multicast group IP multicast?  I understand that protected switchport may provide unicast and broadcast on protection and not multicast.

  You can consult the document "efficient video Distribution networks with Multicast: IGMP Querier and PIM - DM" downloaded here: "".

  http://en.community.Dell.com/TechCenter/networking/p/guides-legacy#PC

  Scenario 2 starting on page 12 shows the steps on how to configure multiple video servers on different VLANS and there are a few test commands to validate the configuration (table 4).

  I hope this helps.

• Multicast traffic stops flowing after a while when using IGMP snooping

  Hi all

  I have the following configuration:

  :

  Where host 1 is a multicast traffic source and host 2 is a customer of multicast traffic. IGMP snooping is configured on both switches.
  Host 2 boots and sends an IGMP report, in order to join the multicast host group 1. Given that SW2 does not know where the mrouter from the group, adds port Eth1/1 to the Group of snooping and removes the package, the IGMP packet. Once host 1 starts, it sends an IGMP query (which is flooded by the port channel), and multicast traffic starts to flow to host 2.
  When I ran 'show ip Mattia snooping groups' I've seen the same result on both switches: on the two switches of the groups the Eth1/1 and the channel port, but after a while, the switch connected to the host 2 deleted the channel of the port of the group.
  After consultation with the switch logs and sniff traffic on one of the channel port on SW1 interfaces, I came to the conclusion that happens since SW1 ceases to send queries generated by host 1 and responding to them locally (some proxy or something). I also noticed that IGMP reports generated by host 2 stop arriving on SW1 (since SW2 do not know that there a connected mrouter more across the channel of the port).

  My questions are:

  1. How does SW1 knows he should keep the channel port as part of the group, if it does not IGMP reports coming from SW2 more?

  2. what happens if the host 2 is not interested in multicast traffic, but do not send and IGMP leave message (a behavior that is supported according to the Protocol, to my knowledge)? How SW1 knows he should cease to IGMP sent from host 1 query response?

  Thanks in advance,

  Omer.

  Hello

  The problem is because you have not mrouter port sw1. It is well documented by virtue

  http://www.Cisco.com/c/en/us/support/docs/switches/Catalyst-6500-Series-...

  There are 3 ways you can solve this problem.

  1. enable Pim on Sw1.

  Or

  2. enable ip igmp snooping interrogator on Sw2

  Or

  3. create staitc mrouter port on sw2.

• inter esxi host ipv6 multicast traffic are not detected by the destination VM

  Hello

  Warning, I do not have in-depth knowledge of vmware, so please excuse the bad wording, misconception and ignorance in the post below.

  The current topology is:

  

  Each esxi 4.1 update 3 (DL380 G8) host is to connect both layer 2 switch.

  on each host, the vswitch has two network cards configured as active/active, with the default NIC cluster approach (route based on the original virtual port code).

  Everything else is default.

  The switches are connected by a link to trunk (not bunk)

  I have two Windows Server 2008 R2 VM in the same subnet and you have enabled ipv6 on them (by default)

  When two virtual machines are on the same physical host, ping-6 destination_ipv6_address works (I just use the link local address)

  When two virtual machines are on different hosts, ping fails with the "destination unreachable" message, which usually means the neighbor discovery process fails (similar to arp in ipv4 where source VM cannot get mac address of the destination virtual machine)

  When two virtual machines are on the same physical host, the the packet capture shows that Neighbor Solicitation message is sent via an ipv6 multicast address

  When they are not on the same physical hosts, packet capture on the VM shows that the destination virtual machine will ever get the destination ipv6 multicast packets.

  I then connect two DL380 G8 in a similar way to the switches and install windows Server2008 R2 directly without virtualization on them and ping-6 works perfectly.

  My questions are:

  -I missed somewhere, a configuration to allow ipv6 multicast to work? Or even to remove any 'logic' and treat it simply as a show?

  On network switches, you can do this by disabling IGMP who will then deal with multicast as broadcast packets.

  Although I can't find a similar setting under esxi anywhere.

  -J' saw an option "Enable ipv6" on esxi, but I guess it's only useful if the host itself to participate in ipv6 and therefore not applicable to my case?

  The only similar question I found the research is on the link below, which suggest to hardcode the next table on virtual machines, which is not ideal.

  I can confirm however, hard coding the table nearby on two virtual machines to work. This problem seems to be on how esxi vswitches manage ipv6 multicast traffic

  ESX4 and multicast

  I don't know if this will really solve your problem, but it is worth trying to update the firmware of the NETWORK adapter and the driver.

  Looks like it's a HP NC 331FLR NIC (gen8 DL by default NETWORK 4 ports with the BCM5719 chip card).

  There is no binary updates that you can run from the 4.1, but you can update all the components of the firmware with the current Service Pack HP for Proliant image:

  HP Service Pack for ProLiant

  Or start the server in a live Linux of your choice and use the Linux binary update:

  http://www.HP.com/swpublishing/MTX-ec0e18db6a8e4d978b57aa95d1

  These will update the NIC 331FLR to the Boot Code version 1.37/NCSI 1.2.37.

  Then update the tg3 driver in ESXi with this set to 3.129d.v40.1 offline:

  https://my.VMware.com/group/VMware/details?downloadGroup=DT-ESXI4X-Broadcom-TG3-3129DV401&ProductID=136

  You need the file bundle offline (BCM - tg3 - 3.129d.v40.1 - offline_bundle - 1033618.zip) in this package. You can import in the vCenter update manager for easier deployment or install it (probably) ESXi shell with esxupdate--bundle=/tmp/BCM-tg3-3.129d.v40.1-offline_bundle-1033618.zip

  I'm a little rusty in the Department of ESXi 4.1 CLI however, you may need to use the vihostupdate utility or with PowerCLI Install-VMHostPatch remote:

  https://pubs.VMware.com/vSphere-4-ESX-vCenter/index.jsp?topic=/com.VMware.vSphere.upgrade.doc_41/esx_upgrade/patches_updates/t_host_upgrade_using_vihostupdate_esxi.html

• Cannot receive multicast on a host of network multi interface

  Can someone please help?
  I'm not able to receive multicast on a host of multi network interface.
  This is the code:
  
  public class LegacyMulticast {}
  Public Shared Sub main (String [] args) throws IOException {}
  Group InetSocketAddress = new InetSocketAddress ("224.10.20.30", 12345);
  NetworkInterface iface = NetworkInterface.getByName ("eth3");
  MulticastSocket socket = new MulticastSocket();
  socket.setSoTimeout (5000);
  socket.joinGroup (Group, iface);
  Byte [] b = new ubyte [4096];
  Datagram DatagramPacket = new DatagramPacket (b, b.length);
  try {}
  Socket.Receive (Datagram);
  System.out.println ("Success");
  }
  {} catch (SocketTimeoutException ste)
  System.out.println ("failure");
  }
  socket.leaveGroup (Group, iface);
  }
  }
  
  The funny thing is that when I run this code, Wireshark detects IGMP join on the correct call joinGroup network interface, followed constantly UDP traffic to the correct port I have to receive and finally I see correct IGMP leave caused by call leaveGroup and UDP traffic stops.
  I just do not get anything on socket.receive appeal.
  I'm trying to understand this one for days now. Pls help someone :)
  
  P.S. I thought to security, but call System.getSecurityManager () returns null.
  P.P.S. I also tried to implement this IAN, but with the same result.

  Group InetSocketAddress = new InetSocketAddress ("224.10.20.30", 12345);
  NetworkInterface iface = NetworkInterface.getByName ("eth3");
  MulticastSocket socket = new MulticastSocket();

  MulticastSocket socket = new MulticastSocket (12345);

  You don't listen to the correct port.

• Probes IPS from multicast traffic

  The ASA/AIP-SSM modules pass multicast traffic when it is configured in online mode?

  -Bob

  Hi Bob,

  The AIP - SSM acts as a L2 bridge when it is used in Inline mode, so it must pass very well multicast traffic.

  I did some research, and unfortunately, there is a bug that would prevent do this according to me:

  CSCtb82257  Multicast sending to the AIP - SSM module affects Dimethylacetamide 0000.0000.0000

  Since it is not fixed yet, I advise you to have multicast traffic circumvent the AIP - SSM and send unicast traffic to it.

• Messages receive do not all messages

  Last week, text messages I receive are not appearing in Messages on my iMac running el capitan.  It seems that my iMac will not show messages from others using iOS because all of the texts have the blue background.  My iPhone 6 and Apple Watch will show me all the received texts, even the most 'green' a person outside the ecosystem.  I confirmed that show the preferences on my iMac that join me by my phone number and my apple id email address.  On my iPhone, I confirmed that the transfer of SMS is activated for my iMac.

  I'm not 100% sure, but I think that has happened after my iPhone update 6 and Apple Watch to the most recent update.

  Don't know what to do.

  Thank you

  According to Messages (El Capitan): get and send SMS messages it sounds as if you already set up correctly the text message forwarding, and it should work exactly as you describe.

  That really should be all it takes, so by way of troubleshooting, I suggest you focus on the iPhone because I suspect that that is where the problem may lie: Unlike an iMessage, SMS messages are 'transmitted' from it to Messages of your Mac app, and apparently happening.

  Try the usual methods of iOS, e.g. restart the iPhone If you don't have it already. Toggle the selection of 'text messages transfer' of your iMac. Review the requirements of the SMS of the following section: continuity of use to connect your iPhone, iPod touch and Mac - Apple Support.

  That's all I can say for now. While this works for me, it could certainly be a bug introduced in the last update that does not affect everyone also.

• The printer receives do not all data. It is caused by the MAC address filtering.

  How can I solve this problem.

  The printer attempted to join the network but does not receive any data.  This may be caused by the MAC address filtering. If MAC address filtering is enabled and you want to keep enabled, add the MAC address of your printer in the list of devices allowed for your wireless access point or router before continuing.

  Not at all use MAC filtering.  Make sure it is off in your router.

• The CALLED RECEIVER will assume all additional costs?

  Hello.

  I understand that he has had several discussions with a similar question, but the thing is that the answers provided were completely irrelevant.

  Ce_que I want to personally know is and perhaps others too: if I made a call via Skype from a computer to a number of portable stranger who did not have Skype installed, the person RECEIVING the call will have to pay as if 1) THERE WAS A CALL MADE overseas (which implies that there are additional costs involved), or 2) a CALL FACT LOCALEMENT (involving there is no international roaming charges) etc. ; costs are exactly the same that it would cost the receiver if the call was made from a local phone number)?

  Please understand that direct me to the page of international call rate will not help me, because I want to know if the receiver will have to pay additional fees to pick up the phone when I call from abroad, NOT from the APPELLANT.

  Thank you.

  Thank you.

  Hello

  First of all there is no 'international' with Skype calls. All calls are 'local' in the world. It's because Skype calls travel goes internet and only "break" to PSTN/cell at one point close to the recipient's phone. The same applies if you call the other side of the world or simply call your neighbor.

  Calls to a mobile phone (from anywhere) are so "local". Skype does not receive calls. If the cell phone carrier charge the owner (some do - others do not), it depends on Plan of the owner of the relationship with the carrier. In any case the call (from anywhere) will be seen by the carrier as 'local' and reception fees (if any) would be only a few cents.

  Hope it clears for you.

  I recommend that you always run the latest version of Skype: Windows & Mac

• Emails received before March all gone?

  I have been using Windows Live Mail as my default e-mail for the last two years and have never had any problems with it so far. I was looking for an email that I received in February to print and my Inbox seems to be unable to load the messages I received before 10/03/11.

  I have one email account and I checked the settings and the program is set to show all messages. I know I didn't delete them all, but I checked section deletion of anyway to be on the right side and found nothing. Emails, that I had deleted a few days ago were still there, so it is not the case that I emptied the "deleted" section
