N5K - N2K Image Upgrade Single vs Dual Homed

Hi,
The upgrade distuptive behaviour is not explained well in the following documentation link . Especially about single homed FEX topology.
http://www.cisco.com/en/US/docs/switches/datacenter/nexus5000/sw/upgrade/503_N1_1/n5k_upgrade_downgrade_503.html
1. I have just upgraded a dual homed Active / Active N2K to N5K environment as below. The downtime was exactly explained as above URL, just the time to reload the FEXs. Which was about 1.5 minutes or so...
Or should we NOT reload all the FEXs almost simultaneously by manual command (as mentioned in the upgrade guide) in this topology, in order to minimize the downtime ?
2.However I am curious if there would be any downtime in a single homed FEX topology as below. My guess is there would be just the downtime for the edge server to distribute the traffic to the other N2K.
I guess if the downtime is really a biggy, then the second topology is easier to manage.
Comments area very much appreciated.

I am not able to see the images you attached, could you please try reinserting them?
Also if I am understanding your question correctly, you are wanting to know if there will be downtime, if you upgrade a N5K with a 2K single homed. I assume you meaning something similar to this?
If so, yes the single home fex would be reloaded per the document it states: "Upgrade the first vPC switch (vPC primary switch) - during this upgrade, the switch will be reloaded. When the switch is reloaded, any dual-homed FEX will not be reloaded. Only singled-homed FEXs are reloaded. Servers connected to these dual-homed FEXs retain network connectivity via the second (vPC secondary) switch"

Reducing the fex time for N2K dual homed to N5K

Hi,
We have N2K dual homed to 2 N5K. The N2K registers the fex with one of the N5K. But when one of the N5K fails it takes more than a minute to register with the second N5K.
How can we reduce this delay so that there is minimum timeout between failover ?

Hi David,
I just noticed that the VPC is DOWN, I think this is the root problem. Any suggestions on this ?

How to replace Nexus5596 with dual-homing N2K

What is the correct process to replace a FEX parent switch with dual-homing fex?
Traffic should not be interrupted.

Hi
Do you have VPC between Parent Switches & are you running VPC on dual homed FEX fabric ports. ?
If yes Below is the procedure,
1) boot the replacement switch without VPC, peer-links & FEX ports connected to it.
2) Make sure it has same Software version matches with the peer switch.
3) enable Pre-Provisioning for slots with appropriate FEX model.
, here find the guide:
http://www.cisco.com/en/US/partner/docs/switches/datacenter/nexus5000/sw/system_management/521_n1_1/b_5k_System_Mgmt_Config_521N11_chapter_0100.html#task_05BB53AD7AFB49CF9A8E4A5C6C37CB38
So, on the replacement switch you will pre-provision the Fabric Extender and configure the ports so it will be ready when you add the module to the RMA SW.
Please make sure you put the appropriate FEX model on the provision slot, otherwise, when connected it will not come Online
Example, FEX 110:
N5K(config)# slot 110
N5K(config-slot)#provision model N2K-C2248T
4) Now keep all ports at Shut down state Then Configure Entire switch that includes FEX host ports, FEX Fabric Ports & VPC peer-link, VPC Domain Configuration.
keep FEX host ports in shut state.
5) keep VPC Role priority on existing switch lower than , new switch
6) Connect Peer-link ports to Peer switch & wait till VPC Comes up-
7) Then connect Fabric ports from FEX to the pre-configured ports on replacement switch
After it comes online Unshut FEX host ports.
I got similar steps here as well
http://www.cisco.com/en/US/docs/switches/datacenter/nexus5000/sw/operations/n5k_vpc_ops.html#wp425197
NOTE: I followed same process however, few ping drops were seen....arnd ( 5- 6 ping loss) only on few hosts...

Single Homed or Dual Homed FEX

With the ability to do enhanced VPCs now on the FEXs is there any benefit to have a mixture of having of single attached FEXs and dual homed FEXs?
Here are some benefits as I see them
Single homed FEX is easier to trouble shoot as the topology is not as complex.
A dual homed FEX will support both dual attached hosts and a single attached host. So this means we only have one topology to deal with (everything dual homed)
Any other pros or cons?
Thanks

If you have any servers with only one uplink, you want dual homed FEXes for redundancy.
Also, it depend on the number of FEXes you are connecting to the same set of switches. For example: the max number of FEXes that can be uplinked to a set of 6k switches is 24 if you are dual homed, but if you are single homed the max is 48 (24 per switch).

Fabric Extender question to a dual-homed N5k

According to latest release notes:
http://www.cisco.com/en/US/customer/docs/switches/datacenter/nexus5000/sw/release/notes/Rel_4_2_1_N1_1/Nexus5000_Release_Notes_4_2_1_N1_1.html#wp144071
"Support for a maximum of 12 Fabric Extenders dual-homed to a vPC Cisco Nexus 5000 Series switch pair and a maximum of 576 hosts connected to Fabric Extenders connected to Cisco Nexus 5000 Series switches"
I have mixed mode so some of the FEX will only connect to one N5k despite the 2N5k will be vpc. Cisco calls this "Fabric extender straight-through topology". This is because I am running port-channel with VM on these particular FEX.
http://www.cisco.com/en/US/prod/collateral/switches/ps9441/ps9670/C07-572829-00_Design_N5K_N2K_vPC_DG.pdf
question is:
1. Can I assume 2148 is included per release notes?
2. Can I have more than 2 ports in the portchannels in straight-through mode?
3. Release notes show 576 host which is (12 max times 48 ports). I assume I can have more logical host meaning vm host via the port channels, right...?
Thx

Any Nexus 5000 can have a total of 12 FEX's connected to it physically. If you have 12 FEX's in dual-homed mode, then that is the limit for both Nexus 5000's. If you had 24 FEX's evenly distributed between the Nexus 5000's in straight-through mode, then that would be maximum in that configuration. If you are mixing straight-through and dual-homed configurations, you would have to be within the 12 FEX per Nexus 5000 limit.
The 2148 is the first FEX, so yes it is the focus of the release notes.
The 2148 cannot have a local port-channel. This is why you can only channel to a 2148 when using dual-homed (called Active-Active mode), one interface on each 2148, and it is tied together with a vPC configuration to make a port-channel. The individual 2148's each only have one connection on them down to the server below. The 2248 and 2232 do not have this restriction.
As of 4.2(1)N1(1), 576 refers to host interfaces. If your host has virtual hosts, you just need to make sure you are within the limit of mac addresses in the system, which is 16,000 (13,800 unicast).

Will the single or dual quad be right?

Does some have experience to advise me, which model, the single or dual quad "new" Mac Pro will deliver better results for editing images in Photoshop, Lightroom, Capture NX etc. And how much ram is a minimum for same with the new DDR3 type? Also, I do part time video editing (Final Cut Express). Thanks.

The cpu is smarter than that, and smarter than we are. A lot of things are going on below the surface, and in less than a nono-second is even a stretch in time, and changes. A core doesn't shutdown.
I suggest you actually dig into the technical papers and articles on Nehalem if you want to understand it more thoroughly. I've read that ARS article three times and still get something new with each read. And there are other articles. I feel like 2008 was just waiting and researching the sucessor to Penryn class (Harpertown).
The specials are just that, and they get 'hand tuned' and physically booted before they go out the door and usually have above the base spec listed.
I am not in favor of bleeding edge. Not until there has been one firmware update and one OS patch and time for 3-4 months minimum to flush out problems that surface. Some are still hoping the next OS update fixes issues with Nvidia 8800GT a year after it came out (and yes, drivers take a year of tweaking, Vista has had two years and apps/games and drivers are an ongoing experiment).

Nexus 5548 SPAN Destination- Dual Homed FEX

I understand that order to setup a SPAN monitor session, only 5K local ports can be destination ports. Our FEX are dual homed, so I know we have to have the monitor session configured on both 5K's. We are wanting to connect an Infinistream sniffer to the destination port. What I am confused about is do we also have to have 2 destination ports, one on each 5K connecting to the Infinsitream or can we just use one?

You cannot set more than one destination to a monitor session. You can have multiple source interfaces, but only one destination. Try this:
destination interface e2/14
You will need to create two more separate monitoring session with the same source interfaces but set the destination to the other two interfaces.
HQ-N5k-2(config-if-range)# monitor session 1
HQ-N5k-2(config-monitor)# source interface e1/17 both
HQ-N5k-2(config-monitor)# destination interface e2/14
HQ-N5k-2(config-if-range)# monitor session 2
HQ-N5k-2(config-monitor)# source interface e1/17 both
HQ-N5k-2(config-monitor)# destination interface e2/15
HQ-N5k-2(config-if-range)# monitor session 3
HQ-N5k-2(config-monitor)# source interface e1/17 both
HQ-N5k-2(config-monitor)# destination interface e2/16

Single or Dual Processors for Tuxedo and/or weblogic 8.1?

We run Tools 8.44 and 8.20 and double checking to see if either Weblogic (8.1) or Tuxedo (8.1) would utilize a dual processor environment? We run these on Windows 2003 Server.
Appreciate inisght.

Yep its all in the cache, and the L3 makes all the difference.
I remember when I was shopping for my upgrade, Gigadesign had two different models of CPU's, the (brand new at the time) single and dual 7447's which went up to a dual 1.8 and the older pre-Freescale models (cant remember the model number maybe it was indeed the 7455B??) that maxed out with a dual 1.4..
I remember reading benchmarks (and quite a bit at XLR8yourmac.com) about the older dual 1.4's being on about the same level as the dual 1.6 and 1.7 7447 cpus.. This was all down to the 1.4 having L3 cache on each cpu. The 7447 had double the L2 like the 7448 but no L3.. I didnt really care much since they were relatively the same benchmark, but I went with the dual 1.7 7447 anyways just because the numbers were higher..
And funny enough, the CPU never ran stable at 1.7, my Mac would crash and kernel panic left and right. I couldnt get any response back from their tech support (I think it was one guy that ran the whole thing) about adjusting the voltage on it, so it spent its entire lifetime in my G4 as a dual 1.67. Not too big of a difference but I couldve saved some money just flat out buying a 1.6 instead of the 1.7, and wouldve saved even more had I just listened and bought the dual 1.4 with L3...
John with a G4 - no problem at all hehe! Dont get me wrong I loved my G4 and it served me well for just about 10 years before it 'died' on me.. But after getting the late-2005 dual core G5 man oh man I wish I wouldve done it waaaaaaaaaay sooner!

Problem in Loading Multiple image in Single Sprite/MovieClip

Hi All,
I am having a killing problem in loading multiple images in single movie clip/sprite using a separate class.
Here is the ImageLoader.as class

        public var loaded:Number;

            } catch (error:Error) {
            imgMc.addChild(image);
            try {
                if (imgObject.URL != undefined) {

        private function onImageLoadFailed(Evt:IOErrorEvent):void {
            trace("Image Loading Failed");
            dispatchEvent(new CustomEvent("CustomEvent.ON_IMGE_LOAD_FAIL"));
Here I am loading some images using the above class in a for loop, like
            for (var i=0; i < 3; i++) {
                //imgLoader=new ImageLoader;
                imgLoader.addEventListener("CustomEvent.ON_IMGE_LOAD",onImageLoad);
                var target:MovieClip=videolist_mc["list" + mcCount + "_mc"];
                target.list_mc.visible=false;
                var imgObj:Object=new Object;
                imgObj.FilePath=list[i].Thumbnail;
                imgObj.Url=list[i].Url;
                imgObj.Target=list[i].Target;
                target.list_mc.urlObj=new Object ;
                target.list_mc.urlObj=imgObj;
                imgLoader.loadImage(target.list_mc.imgholder_mc,imgObj);
                target.list_mc.lable_txt.htmlText="<b>" + list[i].Label + "</b>";
                target.list_mc.imgholder_mc.buttonMode=true;
                target.list_mc.imgholder_mc.addEventListener(MouseEvent.CLICK,onItemPressed);
                mcCount++;
In this case, the ImageLoader.as works only on the last movie clip from the for loop. For example, if i am trying to load three image in three movie clips namely img_mc1,img_mc2 and img_mc3 using the for loop and ImageLoader.as, I am getting the image loaded in the third movie clip only img_mc.
See at the same time, If i uncomment onething in the for loop that is
//imgLoader=new ImageLoader;
its working like a charm. But I know creating class objects in a for loop is not a good idea and also its causes some other problems in my application.
So, help to get rid out of this problem.
Thanks

Problem in Saving Images in Single Folder in Nokia...

I want to know how to transfer images keeping it in folder. I connect my E63 with USB.I copied my "Photos" folder from my laptop,then opened "File Manager" in Nokia PC suit. There I get 2 options. 1)Memory Card 2) Phone Memory.I select memory card, In that I opened Images Folder which is default in Memory card. I paste My "Photo" folder here in "Images" folder in Memory Card.After disconnecting my phone from USB cable when in my E63 I open Media->Gallery->Images I can see all my images of that folder differently and not in a single folder "Photos" which i pasted.So what should I do?I want all images in folder as I copied and pasted. Am I suppose to create new folder manualy in Phone's Media Gallary?But in phone when I go to Office->File Manager and browse through Images folder of Memory card, I find all images in same folder "Photos" which i pasted(copied), but in Gallary->Images i find all images seperately and not in folder. What should I do? Please help me.
Solved!
Go to Solution.

Hey bro thanks for reply..My main purpose for asking this question was related to xplore only. I tried xplore on my E63. When we hide folder by xplore, we browse through file manager.I mean xplore shows Folders that are in File Manager.After Hiding folder, when I go to Gallery->Images, all the images in folder which I have made hiden, are visible,but...but....all the images are converted in one images. Let me explain, Suppose my folder contains 15 images named IM1,IM2,IM3....IM15. ok. After hiding folder in gallery when i See, there are total 15 images but all are IM1.Again when I unhide folder, its normal. I also tried ticking system option along with hide option in Attributes of xplore as someone suggested me to do so.But didn't worked. My main purpose for asking to move all images into single folder was this only.I didn,t knew you too would be using xplore or else i would have directly asked you this question only.
Thanks.

BGP in Dual Homing setup not failing over correctly

Hi all,
we have dual homed BGP connections to our sister company network but the failover testing is failing.
If i shutdown the WAN interface on the primary router, after about 5 minutes, everything converges and fails over fine.
But, if i shut the LAN interface down on the primary router, we never regain connectivity to the sister network.
Our two ASR's have an iBGP relationship and I can see that after a certain amount of time, the BGP routes with a next hop of the primary router get flushed from BGP and the prefferred exit path is through the secondary router. This bit works OK, but i believe that the return traffic is still attempting to return over the primary link...
To add to this, we have two inline firewalls on each link which are only performing IPS, no packet filtering.
Any pointers would be great.
thanks
Mario

Hi John,
right... please look at the output below which is the partial BGP table during a link failure...
10.128.0.0/9 is the problematic summary that still keeps getting advertised out when we do not want it to during a failure....
now there are prefixes in the BGP table which fall within that large summary address space. But I am sure that they are all routes that are being advertised to us from the eBGP peer...

i would not expect summary addresses to still be advertised if the specific prefixes are coming from eBGP... am i wrong?
thanks for everything so far...

ACS SE base image UPgrade

HI,
We have upgraded the ACS SE 1112 as following.
Cisco Secure ACS : 4.0.1.42 to 4.1.1.23
Appliance Management Software:4.0.1.42to 4.1.1.23
Appliance Base Image needs to upgrade from 3.3.1.8 to 4.1.1.4 but we are not able to download the package at download centre as it is not available.
Kindly suggest for base image upgrade.
Regards,

It should work as long as you don't miss anything, and yes you are supposed to install an agent that matches the version you are running. You might want to go ahead and put the latest updates on the ACS before you put it into operation. The process is kind of different than other updates. You might want to read my other ACS posts. I recently killed one of my ACS boxes because I did not install the CSUPdate cumulative patch before installing the lastest patch of the same rev level. (i.e. read directions carefully). Make sure you do an FTP backup before updating the software. If anything goes wrong you could have to reimage the box. There were lots of bug fixes in the updates since 4.1.1.

Wireless Controller Image Upgradation

Cisco recommends image upgrade procedure on 4402 WLC to the latest release 4.1 to be performed in three steps:-
1)3.1.105.0 ------>3.2.78.0
2)3.2.78.0 ------->3.2.195.13
3)3.2.195.13------>4.1.185.0
Unfortunately, while upgrade from 3.1.105.0 ------>3.2.78.0
I got the below error message as shown on both CLI and GUI as well.
"TFTP Failure while storing in flash!"
I have tried Tftpd32 which Cisco recommends also tried other TFTP versions a couple of times but resulted in the same error.
Could someone please suggest TFTP server software package which will support file transfers larger than 32 MB ?
Awaiting your reply and valuable suggestions.

Hey Sanoj,
I've got similar restrictions on some of my controllers. One thing to keep in mind is that the controller won't actually load the new OS until you reboot. Depending on how restrictive your change control process is, you may be able to attempt loadint the software outside of your change window. Once you have a successful tftp transfer, you can schedule a window for a reboot, which will actually load the new OS. I wouldn't leave too much time between the tftp transfer and then reboot, but I understand your frustration with the tftp transfers... I have about an 80% failue rate on tftp transfers (using tftpd32) over any wan link, no matter how high I set my timeouts and retransmits.

RDS Gateway Best practices Dual-Homed?

Good Day,
I am wondering what is a typical amount of time others see when end users launch a RemoteApp session that goes through the RDS Gateway.
Our two RDS Gateway servers (entire environment is W2k12R2) seem slow to me. They are both Dual-Homed and with a Nic on the DMZ and Internal side of the network. Maybe I would be better off disabling the Internal Nics and reconfiguring the firewall rules
so that everything routes through the DMZ nic?
Steve J.

Hi Steve,
Thank you for posting in Windows Server Forum.
Best practice for any server is depends on your environment scenario as you need to decide whether to place the gateway in DMZ or allow 443 to be opened to the internal network. Placing the RDS Gateway in DMZ is more secure, you can have more information from
beneath article.
