• 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.

• VSAN interrogator multicast with igmp snooping active requirement

  When the switch is "igmp snooping" enabled, I do not understand why VSAN Articles and book require a mrouter or interrogator to define.

  Nexus switch igmp debugs and newspapers, VSAN will send members unsolicited reports every 90 seconds at the address of the group 224.1.2.3 and 224.2.3.4. It is without worrying whether or not we have configured for VLAN mrouter or igmp snooping querier. As long as VSAN is coded so as to send the membership periodically reports, should we not there so a "questioning" on the virtual LAN to send Group/General requests.

  As in my tests, I have no igmp mrouter or defined vlan VSAN and VSAN applicant all communicate are good with igmp snooping enabled (default for NX - OS).

  We found that for some providers of network switch, an interrogator is required when you enable IGMP snooping. If espionage works without an interrogator for your specific provider, then this is ideal. In all cases, we recommend that you consult your provider for their specific recommended configuration of switch of layer 2 multicast switch.

• RTMFP Pure IP Multicast - AMS in DMZ - Firewall Config

  Hello

  I am currently helping put a server responsible for AMS of live broadcasting to a pure multicast IP behind a DMZ group. The DMZ is through a Juniper firewall that supports IP Multicast filtering.

  I'm assuming that the following rule must exist:

  • AMS Server video editing to the multicast IP and Port used by pure IP multicast address.

  Any other rules do exist? For example, incoming communication on the server of the same AMS address multicast IP and Port through the other nodes that are part of this pure IP multicast group?

  I searched the forum and do not see anything immediately obvious and the only doc Adobe I found mentioned anything in this regard said "In a firewall using the IP multicast"- http://help.adobe.com/en_US/adobemediaserver/DevGuide/WSa4cb07693d123884520b86f312a354ba36 d - 7ffe.2.3.html #WS0914fed73b20fbab5f67e9a31326e030390 - 8000.2.3

  I just need to figure out what holes in punch between the internal intranet network and the Adobe Media Server DMZ.

  Thank you!

  a pure IP multicast, clients send any traffic to the server.  probably you are using RTMFP URI "rtmfp: ' so that customers don't know anyway the address of the server.

  It should be the case that the only necessary hole is the server must be able to send packets to the destination multicast address and port.

• 6224 PC kills my network. Help? :)

  Howdy,

  I have a PowerConnect 6224 that I use at home on my home network.  I recently started having a really * internet connection with Pings in the range of several hundred.  My configuration is very simple:

  Cable modem-> Wireless Router-> PC-> stuff 6224 (printers, VOIP, file server computer box, etc.)

  If I go to www.pingtest.net with everything connected (I'm on wifi to router), I've been around average a 300ms ping response.  Then, I found that if I simply unplug the router to the switch and run the test again, I get a sub 20ms ping without making any other changes.  If I can plug it in the switch back in, my pings are up in the scale of several hundred.

  Then I unplugged the switch for a bit and let it restart.  I have rant pingtest again, he jumped up to autour 95ms ping.  It's much better than it was before the restart, but still not as good as I would like.

  If it seems to tell me that the traffic from switch is to flood the router with something that is causing all the average traffic to slow down.  When I brought the home switch, I installed the latest firmware and reset all settings to their default value and has not changed anything.

  I wonder if there is some setting I should change the switch that could help with this problem.  Should I just used to reboot it every so often?  What can I do?

  Thanks for any help!

  The switch should not be restarted regularly. Most of the common time for a reboot is when you do the firmware updates. The latest firmware is 3.3.15.1.

  http://Dell.to/2c7auvh

  While the problem is occurring, I'd take a look at some of the controls, see the following. The output may help to better identify the possible causes.

  Show # command logging, will give you the output of any saved messages. If there are errors messages, they can help to better identify the possible causes.

  You can use the command # show interfaces counters to check all interfaces with errors, or the high amounts of packets compared to the total of broadcast packets.

  Use these commands to check the resources on the switch. # Show processes cpu and # see the cpu memory. If they are on the high side, it can affect performance.

  While the problem occurs, you can try unplugging the devices that are attacked to the switch, instead of disconnect switch of the router. Disconnect one at the time and a test to see if there is an impact on the network.

  Keep us posted on your results.

• Help design 6224 Vlan stack config

  Hi all

  I'm looking for help for what I feel should be a simple configuration.

  I have 2 6224 switches in what will be a stacked config.

  I need to put in place the following VLANs

  VLAN Database 5,6,7,8,9,90,100-254

  VLAN 6,7,8,9 should be isolated from each other.

  VLAN 100-254 should occupy 12 ports to resources shared between the two switches (6 per switch). 18-24 ports each switch.

  VLAN 100-254 should be able to communicate with vlan 5 via IP routing Vlan in the switch.

  Each of the VLAN 100-254 will have a 24 assigned ip subnet.

  I am new switches from Dell and I'm a little wrong with setting to the top of any help would be greatly appreciated.

  To create the VLAN on the 6224 orders will look like this.

  Console # config

  Console (config) # vlan database

  VLAN console(config-VLAN) # 2

  output console(config-VLAN) #.

  To place a port in an OFFSET, you use the channel-group command on ports you want in this SHIFT.

  The following example shows the 1/g5 port to the port-channel configuration

  Number 1 without LACP.

  Console (config) # interface ethernet 1/g5

  Console (Config-if-1/G5) # channel-group mode 1 on

  To allow multiple VLANs through a connection, you would use general/trunk switchport mode.

  Console (config) # interface ethernet 1/g5

  console switchport mode trunk #.

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

  Console # end

  When you make the VLANs, they will inherently be not able to communicate with each other. So that they can communicate with each other VIRTUAL LAN routing must be enabled. Here are the basic commands needed for the VLAN routing to work.

  Console #config

  Console (config) #ip Routing

  Console (config) #interface vlan 2

  Console (config-if-vlan2) #routing

  Console (config-if-vlan2) #exit

  Console (config) #interface vlan 3

  Console (config-if-vlan3) #routing

  Console (config-if-vlan3) #exit

  Console (config) #interface vlan 4

  Console (config-if-vlan4) #routing

  Console (config-if-vlan4) #end

  If you have some VLANs, you do not want to communicate with any other VLAN, you should be able to do so by activating only not routing on VIRTUAL LAN.

  If access restrictions are to go beyond that, you may need to look at the implementation of the CAA.

  Here are a few blank pages that go on the use of ACLs and their implementation.

• How to detect 'real' rates to send to peers with the help of multicast?

  Hello, everyone.

  I have a question, I try the demo with

  http://www.Adobe.com/devnet/flashmediaserver/articles/p2p_rtmfp_groups.html

  and then I try to find the 'real' rate of sending data to peer with using multicast.

  I set a timer and it will work every second what app start with "_incomingSteam" (videopodcast )

  and I followed NetGroup.info and NetStream.multicast.info (_imcomingStream.multicast.info).

  who is the real rate outstream when Subscriber send video footage of other peers?
  

  multicastInfo.sendControlBytesPerSecond
  multicastInfo.sendDataBytesPerSecond
  multicastInfo.bytesPushedFromPeers
  multicastInfo.bytesPushedToPeers
  multicastInfo.bytesRequestedByPeers
  multicastInfo.bytesRequestedFromPeers

  Is sendDataBytesPerSecond or bytesPushedToPeers or?

  someone could help me?

  HOPE EVERYONE HAVE A GOOD DAY

  It depends on what you mean by 'real' rate of sending data to peers.

  "sendDataBytesPerSecond" represents the payload data rate, the real info sent.

  "sendControlBytesPerSecond" represents the flow of flight data that would be headers, control messages, etc.

  Sum of the 2 above should give you a measure of the 'outbound' peers; -What are you looking for?

• VPLS multicast support

  I want to deploy muticasr on VPLS, all can you me, wthether is possible and also what are the design and implementation considerations I should have?

  Brgds,

  There is nothing like EoMPLS or VPLS helps multicast up to now, the VC PW are transparent to the traffic running through them and endpoints maintain the State of what needs to be sent on a PW.

  That said, the order for reference are taken by the endpoint based on MAC table formed by using native ethernet method of flood of learning and transfer.

  Let's look at this topology;

  SW1 SW2<---><--><--->SW1 SW3.

  Now suppose that they are simple switches are connected using normal ethernet ports and fiber/copper.

  Now, if enable us igmp snooping and start multicst traffic of SW1 SW2 receiver, then

  first of all it would be flooded on the interface of connection both SW2 and SW3 SW1.

  Once the State of the receiver is discovered and the outgoing interface is known as interface

  interface to SW3 SW2 connection is cut. and there will be no more flooded

  through this interface for this group.

  Now in VPLS these interfaces for interconnection are replaced by PW. If you have a logical connection

  between SW1 and SW2 SW3. And also endpoints PE cannot maintain state multicast regarding PW VC until now.

  The work on this project VPLS group studying this aspect for the introduction of snooping or multicast State of maintenance in the ot PW VC relationship. until then, he is considered unknwon and flooded through all the neighbors on a PFD VPLS instance.

  So if you deploy Mcast on VPLS, it will be broadcast through the PW VC connection,

  at least scale you can do thing to have a star VPLS between the source n

  and the destination. If you try to dpeloy this multicast for access over metro-E clouds separated on through MPLS cloud.

• Configure load balancing NETWORK for Exchange 2010 - unicast or multicast

  Howdy,

  We are in the process of setting up CASE on VSphere and want to configure NLB. The documents I've read talk about using unicast or multicast modes. Unicast requires more setup server-side and multicast requires additional configuration on the side network. A mode is better than the other?

  Any help would be appreciated!

  Lily, multicast is generally the way favorite due to changes to the requirements to the vSphere host, when you use the multicast mode.  The necessary change disables ESX update upstream switches when a virtual machine is online.  Which means that the switches know where VMS obliging NLB to flood the switches, which is design as well as NLB works.  One effect of this is that the switches will also not learn changes due to vMotion or HA events that extend the time it takes switches to learn that the new location for a MAC address.

  Multicast road requires a static entry in the network layer and does not have the effect shown above.

• Constantly flooded with pop up / phishing scam messages!

  Hi, I was wondering if someone could help. For the past 2 weeks I've been flooded with boring jump - rises from the constant / phishing scams "congratulations you have won..." "on my iPhone and an iPad 2! It has gotten to the point now where I can't use any of these devices! as soon as I use safari, google chrome, most apps for example BBC News, BBC sport, etc... It automatically goes to the prize / competition messages and can't click on them. I was not on all questionable websites, just news and sports that I used for years, starting by it seemed to be only BBC sport app but then quickly spread to all! It seems also occur just after I did the last software update, do not know if this is related to the problem?

  So far, I have:

  • Removed from web history (several times)
  • Completely erased and reset all devices and set up as a new iPad / iPhone.
  • Created a new Apple ID, incase it was related to my original account.
  • Make sure blocker made in the settings.
  • Been in the apple store for help twice, they just did what I had already done. He seemed to disappear when in the Apple store, but as soon as I got home n used them once again, he was back!
  • I tried installing apps blocker, but they did not work, and most are not comparable with iPads.
  • Messaged Apple on the Live Chat, but they did not help, just what I had already done before.

  I'm completely lost what to do next.

  If anyone has any suggestions on how to get rid of these horrible annoying messages / pop - ups, I would be very grateful.

  Thank you

• 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.
