• Switch Standard virtual Teaming and Failover/Failback w / button batteries

  Hello

  Small question about Standard virtual switches and nic teaming/failover.

  I have 4 phy cards network connected to a single vSS; two are defined as active adapters (vnic A & B) and two are defined as standby adpaters (vnic C & D). The first two active adapters are connected to a primary switch stack using an etherchannel cross-stack and the two other standby adapters are connected to a driving switch stand-by also using a cross-stack etherchannel. The primary and standby switch stacks are not connected to each other (in a stacking context) but are connected to the same physical network.

  Here's my question - if A nic fails, nic C or D will become active. Let's just for arguments sake adapeter C become active. So B and C card are now involved (for vmware). When C becomes active, the network see B and C adapter as a team even if they are spanning two batteries of different switch - this will create duplicate the network MACs? If Yes, what is the proper way to shift several cross-stack etherchannel teams?

  The physical switch batteries are Cisco Catalyst 3750 s.

  Thank you!

  ... why bother you even create etherchannels...

  There may be special use cases where you have a high traffic going out to a lot of targets with different IP addresses. Personally I never used EtherChannel in ESX (i) environment to date.

  With the default strategy, VMware uses a turnstile mechanism, where virtual NETWORK card a VM is assigned to a physical connection when the virtual machine is running. It is usually sufficient to balance traffic. ESXi 4.1 and the appropriate license (required vDS), VMware has introduced a new policy of load after grouping , which can also interesting to look at.

  And, when using an etherchannel, why is-IP-HASH the technique only balancing?

• How to stop multiple self-switching to the address bar every time I open a new tab and try typing something anywhere outside the address bar?

  How to stop multiple self-switching to the address bar every time I open a new tab and try typing something anywhere outside the address bar? As something just wants me to use this integrated search when you type something non-Web-address in the address bar and press to enter. And the most ridiculous thing is that happens repeatedly on as every second, as I just got off the address bar and start typing again, but still he passes me in the address bar, then 3, 4 times like that. And the result is that I don't see the address of this page.

  I think that its has something to do with my AVG Antivirus, because it started the same time a Nation AVG started to appear in each new tab I opened (and which is irritating as me, I've read here on support.mozilla.org and it seems that the only solution is to completely reinstall Firefox, but I don't want to lose all my settings) but when I type something in the address bar and press enter It opens the search results in Google.

  Please try to help me, I love Firefox but I have to switch to Chrome until I fix this.

  Thanks in advance

  First of all, please update Firefox 32. 22 is no longer support is not safe. So, let us know if you still have this problem. Update Firefox to the latest version

• 4506E Core and 2960S access IP Camera System switches

  Hi all

  I implement my first Cisco network and needed a little guidance. Here's the scenario and I wish that it works:

  • 2960S access switches will have cameras IP PoE and POS stations connected to them with the core fiber uplinks.
  • 4506E central office switch will have all the switches connected to the fiber SFP uplink ports access. All fiber optic cables are single mode with LC connectors.
  • All the cameras IP PoE and the other the camera server NETWORK card will be the 172.16.0.0/16 network and in case of default Vlan 1.
  • All computers of end users and a NETWORK card in the camera server will be on the 192.168.1.0/16 network and Vlan 2. 2 VLAN is needed as the main switch.
  • All stations of POS and stand-alone server POS will be on 192.168.20.0/16 and Vlan 3 switch network access and the base.
  • It will be a completely closed network, no internet access.
  • Computers end users will access video server with raids unicast.
  • All switches interconnect fiber SFP transceivers of 1 GB.
  • VLANs are not to communicate with eachother, just need to Vlan 1 and 3, be passed on to the switch base. It will be setting ports in the trunk switchport mode correct?
  • I gave all the devices static IP networks, with the exception of IP cameras that will get the IP Address of the DHCP server.
  • When I plug in a device of watt PoE 15.4, is the port set to auto detects by default so it lights camera or manually activate PoE on the port?

  -I have to run DHCP on central switch, only on the default Vlan 1 172.16.0.0/16 network so my IP cameras can obtain an IP address.

  IP dhcp pool cameras

  network 172.16.0.0 255.255.0.0

  default router 172.16.0.1

  -On the PoE IP camera and POS station ports I think following configuration:

  switchport mode access

  spanning tree portfast

  I would like to know what you think. I have a few weeks before they must go to the production. Any help and advice will be greatly appreciated!

  I will be checking periodically the thread and display updates.

  Yes I see!

  So with each carpet use "port 1' for each channel.

  for example

  If we have a stack, there that a single etherchannel, should therefore be port-channel 1 (the first 6). This could bind to the 4500 to Portchannel 1

  When we have the second battery, it will also be an etherchannel, which is the port-channel 1 (the first 6).

  This could bind to the 4500 on Portchannel 2

  and so on... The port-channel number is locally meaningful only so you don't meet for loops if its configured as suggested, etc...

  This way you can keep it simple and you will have ease of management in this way.

  No, there is no point linking medical examinations to configure

  Hope it makes sense.

• Cam of the NAC could not add the access switch

  Hi all

  My problem is I can't add the access switch to the cam using mozilla firefox or IE.here attech file cannot add the device. Any idea to solve my problem?

  Hello

  Plese note to add a device (switch) to the CAm, you must go to the leadership of OOB-> appliances-> New.

  First, you must configure the SNMP settings on the switch and the cam so that the cam and the switch can communicate.

  I advise you to make sure that carefully read the configuration for OOB guide and management switch:

  http://www.cisco.com/en/US/docs/security/nac/appliance/configuration_guide/48/cam/m_oob.html.

• (S) synchronization NTP on SG300 access switches?

  Hello

  In our network, two domain controllers are configured as central (S) NTP servers. Mode Layer 3 it is quit easy to sync with these (S) NTP servers. But what is actually the best approach for access switches mode layer 2, which are connected to the layer 3 switch? The only IP address, they are part of the management VLAN ID 1, which is not routable. I actually need something like a show without having to put a NTP server in management vLAN.

  Boudewijn

  Is your switch to level 3 of the entry door for your VLAN? VLAN 1 can be routed, the only restriction to this would be if you don't have no roads to vlan1. If your NTP server and Layer 2 switch points their default gateway to your layer 3, level 3 switch switch can route traffic across this way.

  It really depends on how you have the network configuration and what device manages routing for you on the local network.

• Creative Suite of Cloud for teams and Single-App license shared on a single account

  Hello

  I'm trying to find a way activate a license for Photoshop CC Single-app (per month) on an account that has two create the Suite of Cloud for teams already in use licenses.

  When I try to load Photoshop CC on the account, he said that the product is already activated - yet when I manage licenses online, the license single-app is not yet activated. How is it possible to activate this license of use? We have already paid for the license (monthly) single-app, but must always be enabled on one of our machines for Photoshop-use only (for the license).

  In addition, support for 'Chat' option does not open anything - he that lists it only as an option again there is no way to really open up a chat window. Pop up blockers and advertising have been disabled too and it still does not load.

  Thank you

  HI Desktops68989499,

• VM Compatibility ESXi 5.1 and later bad (VM version 9) with the network

  I'm having and ESXi host with 10 VM, all connected to the same portgroup on the virtual switch. To allow THT, I created the last slots with 5.1 ESXi compatibility and later (VM version 9), where all the other machines have ESXi 4.x and later (VM 7).

  Now, I'm having the issue 2 machines with version 9 can talk to each other, and version 7 cannot talk to each other. It is not possible to make a ping to a version 7 virtual machine vm version 9 and vice versa.

  
  

  An idea, a re there known issues, something I did wrong? From what I saw that day was to be a major change in the networking between these versions.

  Any help welcomed verrrrrry!

  Thank you, Philippe

  
  

  
  

  OK, after spending a day debugging, convert machines front and rear, delete and remove the NETWORK card I was able to convince the administrator to restart the host ESX - problem solved!
