• issue of layer 3 etherchannel

  Hello world

  I am trying to perform a laboratory on etherchannel

  host1-> layer switch 2 - ethetchannel - R1

  Welcome 2->

  On the site of the switch, we want f1/1-3 in the channel of port layer2 1 and on the website of the router, we want f0/0.0/1 f1/0 so in layer 3 port channel 1

  I am able to configure etherchannel on site of the switch, as shown below:

  SW #show etherchannel summary

  Flags: D - low P - port-channel

  I have - autonomous s - suspended

  R - Layer 3 S - Layer2

  U - in use

  Ports of Port-Channel Group

  I appreciate your help.

  Thank you and have a nice day

  Hi Sarah,.

  A portchannel can be a layer 2 portchannel or a portchannel layer-3 and not a combination of both.  In your config file switch is just a purchase order on the router layer 3 and Layer 2.

  Then, given that you are connected to a router, I guess you want a purchase order later-3.  In this case under the po interface add an IP address on the same segment as the side of the router.

• EtherChannel in ESX 4 issue.

  We have configured our with Etherchannels Cisco 4948 switches, and then I can't ping my host vSphere virtual machine... Any suggestions?

  Our config

  S3(Config-if) #description for network cards

  S3(Config-if) #int gi0/23

  S3(Config-if) mode #channel-group 1 on

• 3650 LACP etherchannel suspended

  This new series of 3650 has been bugs me for a year. A lot of things that used to work is not now.

  Over the last weekend, I upgraded a 3560 X to a 3650. The etherchannel seems to behave differently in 3650.

  Example,

  Interface Port-channel10
  switchport trunk allowed vlan 17.23
  switchport mode trunk

  interface GigabitEthernet1/0/11
  switchport trunk allowed vlan 17.23
  switchport mode trunk
  active in mode channel-group 10

  interface GigabitEthernet1/0/12
  switchport trunk allowed vlan 17.23
  switchport mode trunk
  active in mode channel-group 10

  Now when this config is used in a 3560 X and the terminal is in mode standby (not to communicate LACP) ports go into I - autonomous State.

  The same configuration is now placed in a same scenario 3650, and ports through s - suspended state.

  This may not seem to be a big problem, until I try to send WOL for the terminal. Autonomous State, he will answer, but in the s state effectively the line protocol is down the WOL packet (suspended), cannot get there.

  I was really disappointed after a year through versions 3.3.3 to 3.7.1 there is still funny issues with the 3650 series.

  I hope someone is able to advise if they have a simple fix for this problem.

  Hello

  Add the command no channel of port authority - disable the port-channel interface and this should do what you want for example, interface member will in particular (I) rather than the State Suspended (s) if it does not PDULACP. You may have to bounce the port-channel interface for that to be taken into account.

  Take a read of the command in the section configuration LACP autonomous or independent Mode of the configuration for more details guide.

  Hello

  I tested and got the same result as you, so I think you should stay away from PT to test etherchannels and stick to GNS3 if you can do with the mode on or use real devices if you want to use PagP or LACP.

  Kind regards.

• Failback when using Etherchannel and FCoE

  I have an environment that I am able to dig in for the purposes of learning, but I can't it.  Since I can't make any changes to the environment and experience, I wanted to ask a few questions here.  I'm trying to figure out what that the failback option of virtual exchanges must be defined on when using FCoE and etherchannel.

  The environment consists of:

  • FCoE
  • 2 cards of CNA
  • EtherChannel
  • vPLEX
  • Cluster of metro
  • Nexus 5000

  
  Each host connects to a single vDS and each portgroup is configured to use:

  • Load balance policy: route based on the hash of the IP
  • Active uplinks: two 10 GbE CNAs
  • Eve & uplinks used: no
  • Physical switch is configured for etherchannel.

  
  

  The vSphere networking 5.5 guide says the following for failback on vDS trade option:

  
  

  Failback Select Yes or no to disable or enable failback. This option determines how a physical card is returned to active duty after recovering from a failure. If failback is set to Yes (the default), the adapter is returned to active duty as soon as their recovery, moving the daughtercard, which resumed its accommodation, as appropriate. If failback is set to no, an adapter failing has been idle even after the recovery until another active adapter fails, requiring a replacement.

  
  

  This evokes the assets & Eve links and since using etherchannel requires that all active links with no standby connection, this means that the restore option does not apply to etherchannel configurations?  Or applies to the way in which the load is re -distributed when a link comes back after having been conducted? 

  
  

  For example, that we have a portgroup with two uplinks (uplink1 & uplink2), load balancing policy, the hash value of the IP and physical switch ports are in an etherchannel configuration.  During the normal operation of the IP of the hash calculations (http://blogs.vmware.com/kb/2013/03/troubleshooting-network-teaming-problems-with-ip-hash.html) are made and the load is distributed across the two uplinks.  Let's say the physical switch that connects uplink2 in goes down.  The ESXi hosts connected to that vDS immediately come into uplink2 equation which means uplink1 would only result in the calculation of hash IP?  What is the impact of the automatic restore option when uplink2 is back?  If failback is set to no, uplink2 still wouldn't be in the equation?  If so, how you would get it back in the equation?  Or when the link is up is immediately shot down there regardless of the restore option?  It feels like I'm missing something here. 

  Also, I read that attributing no failback is recommended when using IP storage, because it can lead to port heartbeat that can cause performance issues with the storage.  But I also read that traffic to an etherchannel appears as a single MAC/connection address.  This recommendation apply in an etherchannel configuration?  Are port and MAC stir the same thing?  Or is beating port just at the moment where the link goes up and down and MAC beat is when the MAC's switch between two ports?

  Sorry if these are fundamental questions, but not being a networking guy and not being is not able to experiment makes it hard.  Thanks for any help.

  The Member State of the binding not arise unless the link is established on both sides.

  I agree with the statement portfast. All the links go to an ESXi server do not participate in spanning tree protocols. The goal is to transition to a State of transfer immediately on the link turning upward. This must be paid regardless of the use of an OFFSET.

  LACP will dynamically build the GAL and validate the configuration on both sides is correct. I prefer LACP (dynamic LAG) on any static sort of LAG, but this requires a switch on the side of vSphere distributed. If you have the VDS, using LACP. However, LACP does not solve the problem of covering tree (you still want to avoid using tree covering weight on the SHIFT going the ESXi host).

• Appeal iPhone issues 7 more

  I recently bought the new iPhone 7 more.  Not only am I having problems with the LTE service, bounce back between 3 G and no service I am now having problems with call connectivity.  When you try to make an outgoing call, I get an automatic response from my carrier (Verizon) "it's Verizon, we are unable to complete your call at this time, please turn off your phone and back and try again."

  It is a known issue with the iPhone 7 and Verizon. Supposed to be Apple and Verizon are seeking him. It has been a problem since the phone was released. Do a Google search or search here on the forums for a temporary solution but not a cure.  But basically to stop the LTE oice and data into data only in the settings.

• iPhone 6 more hang freeze issues

  My iPhone 6 more guard suspended (gel) for the past 6 months, I have to reset the whole phone sometimes up to 2 times just to get it to work again. Been a loyal (including my entire family) custome since gen 1 iPhone, iPad, mac book. Am really disappointed with the quality now. Did not bring to the service center since the first day of the problem because I thought that was just a few bugs & was sure that apple will fix it, but after many update of iOS so far, the pesisit still problem.

  iPhone is more quality I've known, hope apple can fix this problem before finally losing the most loyal customers

  Hello BennyFoo,

  Thank you for bringing your iPhone freeze questions here for Apple Support communities. I understand how it is important to have a reliable phone. I'm happy to check this with you.

  The first thing we want to make sure that all of your data on your device is safe. You can perform a backup in iCloud or iTunes using this article: backing up your iPhone, iPad, and iPod touch.

  Once your data is safe, try to turn off your device, then again on the March. Sometimes, that's all that is needed for connections reset and everything working properly again. This article help from Apple will help you to do: restart your iPad, iPhone or iPod touch. If you are still having issues, try force reset then. It is designed to be used when the iPhone does not respond, and it looks to be the exact symptoms that you are experiencing right now.

  If you still experience the same problems after reboot, please try to restore your device from a backup by using this article help: restore your iPhone, iPad or iPod touch from a backup. If you don't have a current backup, please try this help article: If you can not update or restore your iPhone, iPad, or iPod touch. Please pay close attention when you get to step 4 who said "when you see the option restore or put to update, choose update. iTunes will try to reinstall iOS without erasing your data. "to get your iOS reinstalled. Test if the issue is still ongoing.

  Thanks again and have a great rest of your day.

• Pages on issues of formatting to iCloud

  Hey everybody,

  I created a document Pages using the Pages application on my macbook pro I downloaded then to iCloud Pages so that I can access it from any computer. The issue I'm having is that I formatted some of the text to have a black background and the text to yellow color. For the life of me I can't understand how to change the background color of text on the Pages of iCloud. I beginning to think that changing the background color of text just is not possible on the platform of iCloud, but wanted to put this out there just to make sure.

  I appreciate any help or clarification on this issue.

  Thank you!

  Background (highlight) text color controls are absent in the Pages for iCloud, because it is a subset of Pages for Mac.

  This has been discussed in a previous post here, not so long ago.

• External hard drive mounting issues on MacOS Sierra

  After upgrading to OS Sierra, I found that my USB3 drives, directly connected to my iMac end of 2012, turn off at startup. USB 2 disks are unaffected and connect properly. The only way to access my USB3 disks is to disconnect and reconnect every time I start the computer, then they are ok. I tried to reset the NVRAM, but it did not work. I found Os El Capitan until this issue is resolved.

  Do not mount or actually turns out always the system start? It was not clear in your subject line and content later, what was going on.

  Are they NTFS formatted drives? See the solutions frequently asked and answered forum if they are.

The phone loses the network connection (cell to the & t) and he no reconnect, it will remain just it saying no service. I have to go in airplane mode and outside to force it to look for the network connection.

  everyone knows this? and everybody understand what it could be?

  I already missed messages and a phone call. This could worsen as boring to become a problem. If anyone has any idea what this could be please give me a heads up!

  OH! Another thing I noticed, when the iPhone is connected my signal strength went from-102 to my 6 sec to-86 on my 7! Then when I am connected I am connected!

• Backup issues after upgrade to iOS10

  Dear users of Apple,

  I updated my iphone 6 more yesterday with iOS 10. Phone works quite well. But I have my phone backup problems. I usually back up my phone with my iTunes Macbook (Via cable and sometimes on wifi). But after the update to iOS 10 it seems that I can't back up my phone more. I don't know the real cause of this problem.

  1. I am not able to save my iPhone via wifi data in iTunes. (Previously it was not the case).

  2. I tried to back up my phone using the cable also. Also, I pressed "Trust" this computer, but I get this error message. Please see below.

  Also, I allowed my computer by disconnecting iTunes and logging back there. And yet I have the same issues.

  "iTunes could not connect to the iPhone because an invalid response was received from the device."

  Does anyone know what this answer is invalid can be?

  Do I have to change the settings in my phone or iTunes?

  Help please!

  Thank you very much
