• 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.

• Priority of VLAN on a Trunk port

  What is the easiest way to give a single VLAN a higher priority than the other on a trunk port?  I have two VLANS, VLAN 10 and by default.  I want to VLAN 10 to have a 802 .1p priority 6 and I want the default VLAN priority of 2.  Is it possible in basic QOS mode, or do I need access to advanced mode?

  Thank you!

• The message that it is has no network adapter and not configured. What's wrong???

  I have a Gateway LX6810 - 01 desktop runnning windows Vista Edition Albums Home Premium, 64 bit, 8 GB of RAM, all the latest updates and Service Pack 2. I connect to the internet through the network connection AT & T Uverse high-speed broadband (12gbps). He worked for over two years now with no problems until now. All of a sudden one day after I rebooted the machine there is no internet connection. When I went to the network and sharing Center, I receive a message that there is no installed network devices. SO, I went to the Device Manager window and there is no device listed network but when I opened the "hidden devices" he has been. (Why it is hidden I have not the slightest idea). SO, I went to the BIOS and checked for if ensure the LAN has been "activated" and it WAS.  I don't always get the same message "no network installed devices. SO then I went on the website gateway and downloaded the driver LAN for my machine and my LAN and reinstalled the driver... I ALWAYS get the same message and I still have no Internet connetion. WHAT could be the problem? Although I consider myself relatively smart, I'm NOT a computer guru, so be kind and state your suggestions in the jargon of the 'no' then I'll understand.

It seems to me it is advisable to periodically clean up the database while happen if I said 'yes' to the pop up? This affects one of my saved messages or only deleted ones? It would make me change OE (I don't want)? I need help... I want to go the pop up, but I don't want to dismiss the question if I don't keep my system properly... BTW, I have Anti Spyware & Anti Malware installed I read what what can cause the pop up?       Respectfully Kwik P(whew!)

• Catch 22 - Port Trunk Configurations: how to combine identifiers VLAN native with DHCP (but allows traffic of VM)

  Catch 22 - Port Network Configurations: how to combine identifiers VLAN native with DHCP (but allow the virtual computer)

  I came across a Catch 22.  Maybe someone can restore the directly here.  I found a "witch hunt" for sure.

  It comes with the Ports of junction on the side of the switch of the ESX host network.

  Context:

  Ok. The Setup is a HP Blade C7000 enclosure.  I try to configure ports for switching to the blades.  ESX 3.5 U4 will be installed the BL460cs.  Installation is preferred method: revive unattended.  No problem with the syntax of Kick-Start,

  I am here, it's the side network.

  The problem:

  I find a major complication in that the switch ports must be configured for both traffic Service Console and VMkernel, more Virtual Machine since only two NICs by blade. Not best practices, but we have only two switches Cisco 3020 inside.  The two uplink physical NIC is paired in the same vSwitch.  (No iSCSI does fortunately).

  So the Catch 22 question is as follows:

  If the id VLAN native set up on the switch port, DHCP works of course and the VMware boot loader is able to grasp a binary / packets on the network (FTP Site) and install OK.  But after no installation, no communication with SC unless I set the VLAN id of the SC to '0 '.  The value "4" 0 does not communication, but "40" is the VLAN native.

  If id configuring VLAN native retired from the Switch port, DHCP will not work and host does not have IP address during the VMware boot process.  This is as expected as traffic without label is not assigned an eligible

  VLAN, so no comms.

  The Port of the Switch configuration:

  interface GigabitEthernet0/16

  SERVERNAME description

  switchport trunk encapsulation dot1q

  switchport trunk vlan native 40

  switchport trunk allowed vlan 40-254

  switchport mode trunk

  switchport nonegotiate

  Speed 1000

  No cdp enable

  spanning tree portfast trunk

  end

  Summary

  OK, let's summarize where things are and if possible please attach responses to their digital identity.

  (1) is there a way to delete the VLAN tagging altogether side ESX host? Not only the id '0 '. The problem is with clearly with the VLAN native defined as "40".  If "40" IDs specified on the Group of ports for the Service Console, no joy, no comms. If the id of '0' value, capable of ping gateway and communicate on the network.

  (2) what is the problem with the definition of VLAN native as "40" when the config for the switch port is set as VLAN native "40"?  Or if it was a problem?  Both parameters clearly do not work together.

  (3) a switch receiving a unmarked frame it will assign to the VLAN Trunk native. Ok. Trunking bases and why I need a VLAN specified on the port for DHCP native work.  But it seems that since the id VLAN is set manually even as VLAN native, closed communications and no traffic as possible.

  (4) executives made tag 802. 1 q VLAN native?  I think that it is not and this could well be the problem. Since the id VLAN "40" is not labeled, but try to score the side host vSwitch port group.

  Please let me know your thoughts, community and how in general, we are approaching 2 NIC ESX configurations.

  When trunking multiple VLANs, you either have a default VLAN is nothing is tagged, or you don't.  That's what the vlan native to you, it defines which VLAN would be used if no tag is visible on the packets traversing the network.  For servers, if you are marking, then everything has to tag, if you're not marking at the server level, then the port must be either an access port or a VLAN native or default must be set.  I also don't keep your service console the same network as your vm.  Keep this isolated for the security of the network.  If you isolate this VLAN, you can separate and use a single IP address for installation and one for post construction.

  Or, you can provide an IP address during the build.

• Question of vlan native

  What is recommended for the vlan native?

  Please let me know if my interpretation of the vlan native is correct.  The vlan native exists only on the ports of junction and isn't the only one vlan tagged across this trunk where all other VLANS on that would be labelled.  No access port on the switch that do not belong to a vlan will have their traffic included in the vlan native and sent through the trunk unidentified.

  I know that the vlan native on a port that has been configured as a trunk by default is vlan 1.  What are the best practices and the reasons why the vlan native should be replaced by something other than vlan1?

  All access ports belong to a virtual local network even if it is only the vlan 1.

  By default the vlan native is also vlan 1, so I can see where you are coming.

  Except that you're right, that the vlan native should be replaced with something else on the switch, mainly because by default, all ports are in the vlan 1 and vlan 1 is also used for other things as well.

  Make the vlan native one vlan unused example. VLAN 999 is a common one.

  There should be no port end assigned in, any SVI (L3 of the interface vlan for it) and you do not need to enable through the trunk or a link.

• WLC management port is another trunk that vlan native

  Hello

  I installed my first WLC 5508 with this topology:

  WLC connected trought distribution SFP 1 GB port to the port of switch configured as a Trunk port cut 3 Wireless VLAN:

  -Management WLC, wireless and wireless voice data Vlan (Vlan native is WLAN Management).

  -J' created 2 dynamic interface on WLC on my VLAN Wireless:

  10.7.1.0/24: default management Virtual Interface installing WLC +.

  10.7.6.0/24: Virtual Interface of voice and

  10.7.2.0/24: Wireless Data Interface virtual trought GUI.

  DHCP configured on each dynamic interface is the interface vlan L3 subent for SWITCH main technical IP DHCP Pool equal VLAN.

  WLC management interface IP address is: 10.7.1.10/24

  I create 2 WLAN SSID name with given ID 1, and ID2 voice.

  I create and AP group named APGRP1 that contains the AP recorded about WLC and using the two WLAN SSID.

  The two AP are connected to the switch acess port configured as native management WLC VLAN access port.

  I have to create 3 IP DHCP pool on main switch with the related L3 Interfaces for Inter VLAN routing.

  Problem: when I try to connect from mobile data SSID I get IP address of management WLC VLAN a VLAN data no.

  the same case of Wireless IP Phone configured with voice SSID.

  What I can likely that allows two devices to get the address IP of the correct VLAN?

  Hi Adil,

  T1 > coelio AP on the switch must be configured on a mode of access to the port or trunk mode?

  YEARS - the LWAPP / CAPWAP APs connected to the switchport should be an access port not trunk.

  Q2 > if the first case, the configuration of the port, on the same VLAN as WLC management VLAN support Vlans other WLANS (voice and data)?

  YEARS - Yes it supports, since traffic that involes the WLAN will be inside the tunnel of logic LWAPP/CAPWAP.

  Q3 > I will check the interface between WLAN and dynamic Interfaces map and I'll tell you.

  YEARS - I will wait for your answer!

  Let me know if that answers your question...

  In safe mode the PVID is 1 VLAN by default. You can do this by entering the command #switchport trunk vlan native {number of vlan}. If Cisco is configured to accept and send the marked packets and has an IP address in the subnet of VLAN 20, it should be able to communicate with other devices in VLAN 20.

• Trunking ports (aggregation of links) does not

  Hello

  I have a single server ESX 4 (hp dl380g5), with 2 natachasery connected to a switch hp 2510 - 48g GB. I created a trunk on the switch ports 1 and 2 and they hooked up to two natachasery ESX.

  I have only 1 vSwitch in ESX and storage space (no VMkernel) that has the Service Console and the network of the VM. I activated this vSwitch (vSwitch0) on IP Hash load balancing to create a theoretical trunk on my 2 GB cards. The two NICA belong to vSwitch0

  When I read/write data to the virtual machine only on trunk ports now seems to manage the data and not both at the same time and with the same flow of data or usage that I expect.

  Is this expected behavior? I have something wrong or bad understand something here?

  Thank you

  Pascale

  I guess you are aware that the mechanism of hash IP packets with an IP - X to another IP - there are always transmitted only a single port physical thorugh, but never through multiple ports at the same time? Therefore, you will never get an increase in throughput for a single "conversation" between IP - X and IP - Y, no matter how much rising physical your chest has. This is due to potential for learning MAC layer 2 and other issues.

  Have you tested with a number of different source/destination IPs connections?

  If you have tested only a small number of connections, you could be 'unlucky' that the hash produced the same uplink of Teddy for all connections.

  Alternatively, you can view the network esxtop notice to see what Teddy what kind/loads of traffic.

• Router not configured for port forwarding

  I use a modem wireless to my ISP, they block all ports less than 1024 and I need to forward ports 80 & 440

  How can I solve this?

  If you configure your router for a LenovoEMC Personal Cloud and always see the message, "Not configured router for port forwarding" under personal cloud Configuration, one or more of the following ports are probably blocked by your internet provider (ISP): 80, 443or port selected in the range 50500-50599 .

  Port 80 is used for internet access (HTML UN-secure) in general. If this port is blocked, but the ports 443 and 50500 are open, the Personal Cloud will work correctly even if the error message appears.

  Port 443 is used for remote access on the host network storage device. If this port is blocked, but the port selected in the range 50500 is open, you will be able to use the Personal Cloud LenovoEMC and invite others to use it, but you will not be able to access your network storage device via the Internet URL. (See answer ID 30773 for more information on access remotely through Personal Cloud LenovoEMC.)

  A port in the range of 50500-50599 must be routed through the router to use the function LenovoEMC Personal Cloud. If this port is blocked by your ISP, you will not be able to access the Personal Cloud to your network storage device or invite others to join the Personal Cloud. (For more information, see answer ID 29070 .)
