The trunk port vs access port speed

• Use of the Trunk Ports (Cisco) on the management interface

  Hi all

  Background:

  We are in the process of consolidation of 2 farms of esx servers and will end up with 10 guests in a single cluster. Guests come from 2 VLAN separate (say 10 of VLANs and vlan 20). A test I took one of the hosts of HA/DRS and tests with it. For HA and DRS to work efficiently and properly in common all resources, we all want vm to leave both VLAN access to move to any host in the cluster.

  The test:

  My single host mentioned above, I created 2 groups of ports on a vswitch, vlan10 tag and with vlan20, I deployed a VM and tried on the two IP address ranges. It worked (with the correct settings of defined IP by VLAN) but as soon as we resources shared the port used by the management of network vmkernel port we lost the connection to the HOST from a management perspective. What the question is that it is possible to connect the management network a trunk port? We have 2 network interfaces connected to the vSwitch and both used for the VM traffic as well as management traffic. That's how they are currently implemented except that the switch port is on a VLAN-specific rather than shared resources.

  Thank you very much

  Hi Chris

  Yes, the network management also accepts the vlan tagging/trunking.

  Just add the number VLAN on the Portgroup.

  Maybe you can do a printscreen with the current configuration?

• ports access the trunk ports - no (or minimal) downtime

  Take even for someone and not an expert, so forgive me if it's pretty simple.  I did a lot of research and that you have yet to see a response.

  There are 4 hosts in a cluster - Nutanix - are NETWORK adapter, all in 1 GB ports in a single switch for a subnet (let's call him. 128/25) currently configured as access ports - no VLAN ID is set to the vm network ports and we use standard vswitches.  The port group is called "VM Network".

  I have 8 new ports on two physical switches now configured with sheath with VLAN ID and 4 VLAN that will be needed in this cluster - where the change.  One of the seront.128/25 subnets I noted above.

  If I leave a host, move cables and configure the port groups for each of the 4 subnets calling prod1 thanks prod4, once the host starts the marking of the packages I will able to vmotion for the new configuration, host of one of the other three?

  Thank you

  Mike

  

  Since you can't computers vMotion virtual from one host to another if the port group name is different, my recommendation is:

  1 evacuate VMs to host you want to create new groups of port with tagging VLAN;

  2. create new groups of port with the appropriate names and VLAN.

  3. on the host without tagging VLANS, create groups of ports but without VLAN.

  4. change the network interface virtual VM on the new appropriate port group;

  5. the virtual machines to the new host of vMotion.

• Message from the USB port speed

  I have a laptop HP Compaq NW8240 running on W7 last month recently, I plugged in a USB USBHUB04 of Linksys hub. It works fine but when I plug a flashdrive in there, it displays a message in the lower task bar "this USB device can perform faster if you connect it to a hi-speed USB 2.0 port. Should I have a missing driver? I thought that all USB ports on this laptop was 2.0.

  Sorry that none of the steps that you took to remedy the problem.

  You did exactly what I would have done it, so unfortunately, I couldn't even begin to tell you what to do next.

  You may have to live with the status quo.

  I wonder if this is a false message...

  Your USB devices work more slowly than normal as a USB HARD drive or flash drive.

  Data transfer seems slower than you're used to?

• PowerConnect 5548p; Apply button missing in the VLAN port settings

  In the user Web interface for my stack of switches 5548p, if I go into the settings of local network VIRTUAL port, click on edit, select a port and change the mode of access on the trunk port, the changes are saved, but then the button apply disappears and I am unable to make changes more.

• on WAP 321 trunk port

  I intend to deploy cisco WAP321 on my client and after rading the document on WAP321, he said the WAP321 support for VLAN ID function, but I can't find that it supports for trunk port because I would like to connect the LAN 321 WAP port to the cisco SMB switch SG300/SG200. is the trunk port already activated on port LAN 321 WAP so I don't have to set up or not?

  need your support and help

  Hey Bram. Yes, it supports the trunk. You configure it vlan untagged on the local networking. VLANS with each switch is no problem.

• SRW2048 - trunk port

  Hello

  I have a question according to the behavior of the trunk port.

  I need to connect Linksys Cisco Catalyst switch. On the catalyst I've implemented the port in trunk mode.

  I also put the SRW2048 port in trunk mode. But the switches are not able to communicate with each other.

  Is it possible to implement on the SRW2048 to accept all VLAN Tags on the trunk port. Because it looks like

  be slightly different behavior of cisco switches where are all the VLAN to the trunk mode port.

  I don't speak dot1q encapsulation (tag VLAN)

  The switch has the new firmware: v1.2.2d

  Thank you for your response.

  Juraj

  In contrast to the catalyst, the SRW does not automatically add all the VLANS on the switch to a trunk port. Instead, you must do all your Member VLAN trunk mode port.

• How to add a VLAN on a trunk port and channal port

  Hi all

  I need to set up a configuration details below.

  1 how to add several VLANs on Cisco 4500 switch trunk port. (vlan existing also will be there)

  2. I have also 2 4500 switch to shared resources and channel ports.

  So my question is should I add new VLANs on the trunk port and port also channel?

  Looking for an answer

  It depends on your existing configuration.  If you have not specified WHAT VLAN is allowed, they would be by default.  If this isn't the case, you need to add the VLAN again to the definition of trunk.

  Too far again go to that VLAN, that also depends.  IF you have VTP really set up, you have to create the new vlan on one of the master switches in VTP (probably your 4500) and the definition spread to other switches.   If this isn't the case, then you declare new VLANs on each switch that would need them.

• PowerConnect 5448, how all the trunk of physical ports and allow all the VLAN tags to pass transparently

  I would like to achieve such a goal, do all acts of switch ports 5448 as 'trunk', that is, just as an entry-level switch. Yes, I want all the tags VLAN through seamlessly.

  Let me explain more clearly. If

  • With MAC1 PC1 is connected to switch port 1 (port 1) in short, PC2 with MAC2 is connected to port 2.
  • PC1 sends a packet with vlanid = 30 ethernet VLAN tag,.

  I want the ethernet packet must be SENT to port 2 without modification, i.e. 2 PC will receive the package with exactly the same byte packets that PC1 sends.

  Currently, I want to configure all ports from the switch to act like this, but how to do this? Can someone tell me the more concise CLI commands to achieve? Alternatively, it is possible via the web interface?

  I must again complain the poor manual, which talks about this concept and this notion over and over again (both of ambiguous statements that the author of manual does not), BUT doesn't explain them not at the level of the content of the packages, so I'm totally at a loss.

  I tried the web interface. Simply together port 1 and 2 for access mode or general mode does not work.

  Please help me. Thank you in advance.

  Thank you, Josh, you begin to point me in the right direction.

  Now, I know just affecting a Trunk port, or general mode is NOT sufficient.  I have to give what kind of package VLAN (i.e. what VLAN ID) are allowed to pass through.

  To do this assignment, I have to take 2 steps. say first of all, the database "vlan" to recognize a VLAN ID in the world, then say that some specific port is allowed to pass through with this VLAN ID specific packages.

  Thus, in order to pass packets VLAN with VLAN ID 18-25 no modified (marked packets in packages marked on) g7 to the g8 to port port, I have to do:

  Console # config
  Console (config) # vlan database
  Console(config-VLAN) # vlan 18-25
  Console(config-VLAN) # exit

  Console (config) # interface ethernet g7
  Console # switchport general mode
  Console # switchport General allowed vlan add the tag of 18-25

  and again for the g8. And if I want to 48 ports to act like that, I have to write this kind of order 48 times right? All the shortcuts?

• Want to 700-230: how to access the BIOS on machine with wireless keyboard and no keyboard on the PC port

  Hi all

  I have a HP Envy 700-230 which has a wireless keyboard

  How am I supposed to access the BIOS that the keyboard drivers are not loaded until after the machine and there is no normal keyboard connects on this PC for a wired keyboard

  With this kind of computor how am supposed to access the BIOS

  Obviously to start the reports a keyboard error and suggest I press ESC to access the BIOS that I can't because at startup, there is no current keyboard.

  Thanks for any help on this.

  Jeanette

  While not a definitive answer, but try a wired USB keyboard instead wireless.  There may be a setting in the BIOS to change the way the keyboard interacts at the start but, of course, you need to enter the BIOS.  Looking at the other comments on this issue, if you happen to have a keyboard PS/2 and a PS/2 to USB adapter, then this seems to be a better choice.  Plug the PS/2 on the PS/2 keyboard to USB adapter and then try that at startup to access the BIOS.  Then, find the setting to allow the keyboard to be recognized at startup.  Another solution is to move the USB port, the wireless keyboard use.  If the rear ports, move forward, if forward move backward.

  Let me know if one of these help.

• Prevention and management of concurrent access to the same port VISA

  Hello

  I currently have a VI with three parallel loop: a loop for the UI with a structure of the event; a loop for the collection of data; and a loop for data tracing.

  The loop of data written to the serial port to put the camera to send a probe reading update. The device sends the sensor updated playback and loop bed devices response data collection.

  I have a situation where the user interface loop must also 1. write to the same device (via the same port), 2. read the answer, then 3. write using the response data and user input. My problem is that the user interface loop is reading the response of devices in the loop of data collection rather than the response to the user interface loop.

  So the problem looks like:

  loop data collection: how hot is?

  device: 30 degrees Celsius

  loop data collection: how hot is?

  device: 30 degrees Celsius

  loop data collection: how hot is?

  loop UI: what color is the sky?

  device: 30 degrees Celsius

  user interface loop: Ok! the color of the sky is 30 degrees Celsius.

  device: Blue

  I'm tempted to look for a solution where the user interface loop interrupts somehow the other two loops while it is writing and reading on VISA port, but I doubt that it is the appropriate solution. My code is big enough, but I can try to view if necessary. I remember seeing messages from people with similar problems, but it seems impossible to find today. Thanks in advance for the help!

  Now that you've been through that we will develop a specific EI style that I call a Module on resources.  A RM exposes only the functions required by a given application to using an external resource while protecting sections of code of "criticism".  In your example even if the VISA operations block several appellants to write simultaineously, you did not protect the operation "Request" critical so readings were responses to the caller of evil.  The 'query' is essential and must block access to other operations until the query is complete.

  Look at this "Very basic" RM implementation that does not protect the critical query operation:

  

• WRT350n - what is the speed of the WAN port?

  Hello

  Virginmedia in the United Kingdom have 50 MB download capability now that I am interested in buying. I was advised to check that my current router (wrt350n V2 firmware v2.00.18) is able to handle this speed on its WAN port before you sign up. It is not clear on the data sheet if the WAN port is gigabut able ehternet, as well as the 4 ethernet ports, and I wanted to ask you just to be absolutely sure.

  Any help or clarification gratefully received.

  Snert

  As the router that you have its a gigabyte wireless router bits, and all the LAN port at the back of the router are the Giga bit Ports LAN. Your router will work with the speed of 50 MB, and you should be able to go online from all your computers.
