Cat3k 3850 stack IOS-XE Upgrade question

I have a stack of three cat 3850 switches running IOS-XE 3.03.00SE. I need to upgrade them to 3.03.05SE to resolve outstanding security bulletins.
Most of the devices connecting to the stack have redundant connections to two different switches in the stack.
Is it possible to upgrade the switch software and reboot the switches one at a time in order to maintain connectivity for the devices with redundant connections? I've been looking at upgrade docs including http://www.cisco.com/c/en/us/support/docs/switches/catalyst-3850-series-switches/117552-technote-cat3850-00.pdf but I don't see this addressed. Back when we bought this hardware, our Cisco account mgr said this would be possible, but I have not been able to verify it.

Is it possible to upgrade the switch software and reboot the switches one at a time in order to maintain connectivity for the devices with redundant connections?
That is not currently possible. You would have to load the new image in all switches and reboot the entire stack.

3850 stack IOS upgrade

Hi,
Is it possible to upgrade the IOS on a cisco 3850 stack in a non disruptive way?
Reloading 1 switch at a time?
Or do you need to reload the entire stack at once, like a 3750 stack?

"And repeat the same command for the second switch"
You actually dont have to do this. First verify that you are in "INSTALL" mode by issuing a "show version." Once you have this file in your local flash, just run the following:
Switch#software install file flash:cat3k_caa-universalk9.SPA.03.02.02.SE.150-1.EX2.bin switch 1-2
**This will expand the .bin file onto your switch and ask you to reload. After reload, you will be on new version

Here is a snippet from my lab – I ran through a quick upgrade from 3.2.0 to 3.2.2

Updating Cisco IOS XE Software
When the switch is in install mode, you can install any new Cisco IOS XE Software bundle by using the software Installcommand.
Note: This command works only when the Cisco Catalyst 3850 Switch is booted in install mode.

Upgrading 3750X Stack IOS (suggestions)

I'm reading all sorts of problematic issues with upgrading the 3750X stack IOS on the internet. I have never performed this before and would like anyone'e suggestion on how I should do this and what I should be looking for. I will be upgrading from 12.2(53r)SE2 to 12.2.(55)SE8.

Let's say you have three 3750X in a stack. OK?
So before you even begin to push the IOS to your switch, you need to download the correct IOS for each member of your stack. Make sure each member of your switch is found in the Supported Hardware list.
Download the "universal" TAR file. Next, once you've downloaded the IOS, make sure you verify the MD5 hash value against the value found in the Cisco website. The MD5 hash value must match.
Make sure that all members of your switch stack have the same licenses and feature set.
Ok, now you've got the preparatory set, you do the actual command to push the IOS into your stack. The command is very simple. Remember, I presume that you have three switches in a stack.
The command is: archive download-sw /destination 1 /destination 2 /destination 3 tftp:///filename.tar
Using the simplified command above, this will instruct the switch to download the IOS from your TFTP server into the switch stack master's memory. The "/destination X" means it will be pushed out to each member one-at-a-time. The boot statement will also be changed so the stack will know what IOS to use.
Hope this helps.

Catalyst 3850 Stack VLANs, layer 2 vs. layer 3 design question

Hello there:
Just a generic, design question, after doing much reading, I am just not clear as when to use one or the other, and what the benefits/tradeoffs are:
Should we configure the switch stack w/ layer 3, or layer 2 VLANs?
We have a Catalyst 3850 Stack, connected to an ASA-X 5545 firewall via 8GB etherchannel.
We have about 100 servers (some connected w/ bonding or mini-etherchannels), and 30 VLANs.
We have several 10GB connections to servers.
We push large, (up to) TB sized files from VLAN to VLAN, mostly using scp.
No ip phones, no POE.
Inter-VLAN connectivity/throughput and security are priorities.
Originally, we planned to use the ASA to filter connections between VLANs, and VACLs or PACLs on the switch stack to filter connections between hosts w/in the same VLAN.
Thank you.

If all of your servers are going to the 3850 then I'd say you've got the wrong switch model to do DC job. If you don't configure QoS properly, then your servers will start dropping packets because Catalyst switches have very, very shallow memory buffers. These memory buffers get swamped when servers do non-stop traffic.
Ideally, Cisco recommends the Nexus solution to connect servers to. One of the guys here, Joseph, regularly recommends the Catalyst 4500-X as a suitable (and financial) alternative to the more expensive Nexus range.
In a DC environment, if you have a lot of VM stuff, then stick with Layer 2. V-Motion and Layer 3 don't go hand-in-hand.

3850 Stack not displayed correctly in CiscoView 6.1

HI,
our customer installed lms 4.2, updated it to 4.2.5 and applied the Maintenance_Release_4_2_5_01_LNX. Its a fresh installation, so there are no previous data. After a discovery via SNMPv3 the 3850 (stacks with 2 or 3 units) show up in CiscoView but only one unit, the others are missing. When I take a look in the fan status, it displays the fan status of the other stack members, so the stack is recognized, but not displayed...
Installed Packages:
CiscoView version is 6.1.156
Cat3850.cv50.v1-0.zip (installed with the 4.2.5 update)
Anybody got an idea how to fix this?
Thanks!

The reason why the C3850 switch stack is showing as standalone in LMS CiscoView is because
it's returning sysObjectID as standalone.
It should return as 1.3.6.1.4.1.9.1.1745 --cat38xxstack
While, if you poll it for sysObjectID, the Catalyst 3850 stack switches will be returning OID 1.3.6.1.4.1.9.1.1641.
This is an IOS bug "CSCul00003 - Incorrect Sys OID for Cat3850 Stack device".
Unless this bug is fixed, LMS will not be able to show it as stack device.
You can try to check if you can manually change the device identity to cat38xxstack from Inventory > add/edit device > edit identity.
Else we need to wait for the fix of this bug.
-Thanks

Problem with stack generation for upgrade EhP6- 7 (IDEX-DE)

When calculating a stack for the upgrade EhP6->7 we encounter the following error:
In long text, it says:
Any ideas? Do I have to include the SPs manually?

Hi Daniel,
Two points:
1. you need to raise this question in the SAP NetWeaver community for assistance as that's where the Basis/NetWeaver experts live.
2. It looks to me at first glance that it requires IDEXDE SP2 to be included in the stack, not SP 00 which you have selected at present.
Regards,
Graham

Security upgrade question - Getting 6.1.6 downloaded to iphone.

Security upgrade question - I have a 4S phone v6.01 with an upgrade to IOS 7.04 already downloaded and ready for install. I would like to install the 6.1.6 security upgrade instead. How do I delete the ios7 in the queue or have the 6.1.1 pushed as an option to the phone?

You can't install iOS 6.1.6 on that device and must update it to 7.0.6.

4500 R+E with sup 8 vs. (3850 stack + 5508 WLC)

I got into discussion about upgrade our 3750 stack, 4404 WLC, less than 50 APs (APs spread out over MPLS WAN). I'm planning to get 4510 R+ E with 2 sup 8, but another opinion talked me down to 3850 stack with 5508 WLC. Basically, his argument is 3850 stack can do everything 4500 R+E can do, plus it's not hulky as 4500. My argument is I like unify access since sup 8 built in WLC and we don't have to get 5508. I know there're more 4500 R+E and respect his argument. Does anyone has input on these setup giving pricing is not much different between setup.
Thanks
Kevin

In my honest opinion, if you are posted this solution here, you are smelling something is off. I hate to be a bearer of bad news. It is.
We went through the same exercise 2 years ago. We wanted to upgrade our legacy 3750/3750G to 3750X and we found out that if we were to get a stack of four (or more ) 3750X, it is cheaper (much, much cheaper) to get a 4510R+E bundle (with Sup7E included) and associated line cards on top. Just to note, the 3750X and 3850 have the same price. The Sup7E and Sup8E have the same price.
Don't ask me why your consultant wanted you to get 3850. I am refraining myself putting two theories in here.

3850 stack problem - duplicate IP

I have a 3850 stack running ip services on version 03.02.03.SE of IOS-XE. I have multiple SVI's on the stack and getting duplicate ip address messages in the logs.
I have checked that the stack has come up properly and they are both reporting ready and are active/standby. I have recreated the stack a couple of times and each time its the same.
Any ideas? Bug maybe?

I have added this command on all the physical ports on both stacks. Still getting the duplicate address messages in the log.
Anything else I can look at? As I say, the stack looks fine and the IP addresses it is complaining about only exist on the SVI on the ipservices stack.
There is a newer version of IOS-XE that is recommended on the Cisco site. Should I go for this?

Up-link 2 x 3750 Stack to 4 x 3850 stack

All -
Sorry is this is a rather simple question but I’ve never worked with Stack switches before? I have a remote office that has 3 floors. On one floor we have a 2 3750s in a stack. On another we have a single 3560 and I’m going to be installing a new 3850 stack – the new stack will have 4 x 3850’s...
My question is how should I uplink the other switches to the new stack? In the new stack I have a master a slave and two member switches. Should I create a port channel from the 3750’s and use all available links and spread them across all switches in the new stack, and then do the same with the single switch on the other floor? Or should I create two port-channels from the 3750 and the 3560 to the new 3850 stack?
My thought is that if I create a single port channel form each switch to the new stack I would be basically be removing spanning tree from the environment and basically daisy chaining the switches? Is this a valid solution? Also does the stack act like a chassis where the control plan would be on the master – if so can I spread a interfaces in a port channel across all members in the stack?
Thanks in advance
Mike

To take advantage of fewest (logical) devices and redundancy, run a dual Etherchannel from your new 3850 to the 3750 stack and the 3650. On both the 3850 and 3750 stacks, insure the same Etherchannel links are on different stack members.
Logically, you would no longer need STP, but keep in running in case anyone accidentally creates a L2 loop.
As to what stack members to terminate uplinks/downlinks on, on 3750s, Cisco recommends avoiding the stack master (not possible on your dual 3750 stack). I don't know what Cisco's recommendations, if any, is for 3850 stacks.
Yes, stacks "appear" much like chassis devices, i.e. stack member ports "appear" like chassis line cards ports.

All day calendar events not being displayed in the notification centre for iphone 5 post ios 7 upgrade. Please help. Is it a bug?

All day calendar events not being displayed in the notification centre for iphone 5 post ios 7 upgrade. Please help. Is it a bug?
With iOS 6, the all day events showed up in the notification centre but it lacks in the upgrade iOS 7.

Same problem here. Some people pointed out that all-day events do show up in their notification center, but that seems only to be the case for birthdays (and only as text like the weather). I've tried it myself on my iPhone and iPad and it did work for birthdays but not for any other all-day events. I already sent this to Apple as a product feedback as well, as should everyone of you. The more people mention it, the faster Apple's going to fix this issue. In its current state, notification center is not a very helpful feature in my opinion. There's absolutely no point in not showing all-day events in the 'today' calendar overview.
Here's a link to the product feedback page: http://www.apple.com/feedback/
I posted my message in the iPhone section since I couldn't find a page specifically dedicated to iOS 7.
I really love the look & feel of iOS 7 but it's kinda sad to see notification center not tapping its full potential.
Cheers!

I am having issues with my Handsfreelink in my 2013 Honda Pilot after the ios 8 upgrade.Basically, music works the phone does not.
What I have tried:
1) Hard reset
2) deleted and re-setup all bluetooth settings on both phone and car
I suspect this is a bug in ios8 that needs to be addressed. On a sidenote I am also unable to plug my phone into the USB port on the car, now says unsupported.

The same thing happened to me on my 2012 Subaru Outback. I'm not sure this will help you since you have a Honda, but I'm posting this just in case.
I paired the audio on my car with my iPhone 6. However, when I turned the car off and back on again, the iPhone would not pair automatically. I had to manually connect the iPhone with the car. Turns out there are two separate bluetooth pairings on my car: one for phone which allows up to 5 devices and one for audio which allows only one device. So I did the second bluetooth pairing for the phone (had already done the audio), and that fixed it. YMMV
