FEX 2232TM not recognized by Nexus 5010P
Hi there,
I don't have any clue what this problem might be so please help.
I have a brandnew FEX 2232TM which is connected to a NEXUS 5010P running the following firmware:
oftware
BIOS: version 1.5.0
loader: version N/A
kickstart: version 5.2(1)N1(1)
system: version 5.2(1)N1(1)
power-seq: Module 1: version v1.2
BIOS compile time: 11/30/10
kickstart image file is: bootflash:///n5000-uk9-kickstart.5.2.1.N1.1.bin
kickstart compile time: 7/12/2012 19:00:00 [07/13/2012 02:08:13]
system image file is: bootflash:///n5000-uk9.5.2.1.N1.1.bin
system compile time: 7/12/2012 19:00:00 [07/13/2012 03:23:16]
According to the Cisco download page it is the latest version and should definitely support the 2232TM.
The problem is that the FEX is completely not recognized by the parent Nexus.
It is connected via 8 FET modules. But when ich check the light on both sides I only have light on the NEXUS side never on the FEX side on all modules.
From my understanding this should be the root cause of the issue because no light = no link.
I tried standard 10GBase-SR and Twinax cables as well. Same behavior - the FEX is not recognized.
The status LED if of course orange on the FEX.
This is the FEX related config ont he NEXUS:

Can anyone give me a hint what I am missing here??
Any help is really appreciated.
Thanks a lot!I have a two lab switches running 5.2.1.N1.1 and connected in vpc with 2232TM and I am able to see the fex online without any problems. One side I have SFP-10G-SR and other side I have 3M Cisco Twinax cable.
here is the output from my lab,

So dont believe we have any interoperability issue with 5010 and 2232TM here. Before we swap out this fex, can you please open a case with Cisco support or let me know when you are available and I can do a webex to look at this switch to see if there is something more to this problem than what we already know ?

Nexus 2K FEX dual-homed to two Nexus 5K Configuration
Hi.
I am trying to look for Nexus 5K config when the nexus2K FEX is dual-homed into it.
What will be the configuration on both 5K especiall the pinning?
Assuming one N2K 10G port is connected to N5K-1 and another N2K 10G port connected to N5K-2?
N5Ks are also configured as dual-sided vpc with two N7K.

Nexus 5548UP VPC and/or VRRP problem
Hi, I have two 5548UP + L3 card with LAN_ENTERPRISE_SERVICES_PKG and FC license.
This two Nexus are the core of my network.
Eight stacks of 2960S are connected to both NX with an etherchannel formed by two SX-1G or two SR-10G.
I've checked the conf and maked a lot of test and everything works fine. BUT, two days after the people start working on the new building, about half of the PC don't even reach the default gateway. (Nexus VRRP)
I've turned off VRRP and it works for minutes.
The problem disappear if I shutdown one of the links to NX01 or NX02.
I followed the destination MAC of one PC with the problem and the ARP table looks OK but I guest the problem is related with a corruption in the ARP table anyway.
system image file is: bootflash:///n5000-uk9.5.2.1.N1.1a.bin
Thanks in advance!

FB 4.7 sees nexus 10 but not nexus 7 - both on android 4.2.2
Hi
I'm completely new to android development and am struggling to get Flash Builder to see one of my devices. When I try to launch a mobile project it simply cannot find the Nexus 7 on the 'choose device' dialog. "Flash builder could not find a connected device"

It then worked perfectly for the Nexus 10. I'm at a loss as to how to get it to see the Nexus 7. Both devices are running Android 4.2.2. PC and devices have been restarted after any changes etc.
Android SDK for 4.22 installed, Google USB driver installed. In device manager Adnroid Composite ADB Interface version 7.0.0.1 installed. If you turn off USB debuging on the Nexus 7 windows immediately see's the device and allows you to browse it via My Computer.
At a loss as what to try next ... any help very much appreciated. Thanks.For anyone else with this issue here is the solution found after much tinkering:
Uninstall the Android Composite ADB manager via Device Manager.
Go to this url and download the USB driver - then install it:

Then in Device Manager re-install the Android Composite ADB Manager.
All then works at it should. -
Connecting 2, Nexus 5K to single Nexus 7K
I dont have dual 7K on the core layer. I only have one, but in the distribution layer I have 2 5ks,
how different would the config be without dual 7K?
Can I create single port channel from both 5Ks to the 7K?
what do I need to be aware of?Based on your daigram you dont need to configure VPC. Simple etherchannel/Portchannel is required.
VPC is required when you are going to connecting the switch to two uplink different switches and want to form the bundle.
To have simplicity I would create two Port-Channel for your setup.
1- Port E3/45 &E4/45 to be part of 1 Port-Channel.
2- Port E3/46 & E4/46 to be part of 2nd port-channel.

Nexus (5010) To FEX Distance Limitations
Hello,
My question is concerning the software-imposed distance limitations for Nexus-to-Fex connections.
With a Nexus 5010 running 4.2 (1) N1 (1) code, I believe there is a software limitation on the distance the FEX can be located from the Nexus. I have two questions concerning this:
Is there any log data, or a cli command, to verify that the fex connection has exceeded that distance?
What symptoms are produced when the fex is too far from the Nexus (ie, does the link come up but the image not load?)
I would like to determine that the reason I have a FEX, located in a second data centre, that is not coming up is actually related to the distance from the FEX to the Nexus and not related to some other problem.
Thanks for any suggestions/info offerred.
SimonI have not seen any reference to a software limitation for the distance between a N5K and a FEX.
The release notesfor 4.2(1)N1) listed si not showing it unless, my first cup of coffee has not kicked in

As far as believe the only distance limitation would be the type of cable used. Either the distance limitation of the SMF SFP or the MMF SFP, or the CX ethernet cable which has reletively short distance spans.
Where is you here about this limitation?
And more importantly, what issues are you have towards the FEX? -
Is SPAN port not allowed in Nexus FEX Port ?
Hi

Ok, I've had dozens of Verizon Phones but something is going really wrong with the Galaxy Nexus that I own. It started out as the best device that I have ever owned. Then I had a problem with it non-related to the signal issues. The tier two tech support had me do a software update on the phone and ever since, the 4G, 3G and phone signal truly struggle. Calls are dropped. Texts wont go through. And internet is often inaccessible. This is all intermittent and untraceable as far as a pattern goes. So Verizon sent me a replacement device. It was worse...to the point that it would not connect to anything reliably, including wifi. They sent me another device and it was more of the same. I am now out of town and having the problems continue with my original phone. A third device is waiting at my house for what Verizon thinks will solve the problem. I'm hoping it is the answer.
Who else is having these problems. Tier Two tells me that this is not a common problem with this phone. It's hard to believe because, I am 0-4 on this device. Also, if you are having problems, did you start having problems in July/August when an update was possibly released?
Let's hear from you!I just bought a nexus fully aware of the signal problems but was assured by best buy that it is a sim card issue and they would repeatedly replace the sim card until it worked. I am running 4.0.4 the phone was updated before I bought it or came with the update as it was in an unopened box brand new. I have not had any issues other than I cant seem to get more than 2 bars of service in places where my old phone had full signal. so for those of you waiting for an update it may fix some issues but as far as I am concerned it does not fix the signal problem. I bought 3 of these phones and all three have not gone over 2 bars in multiple locations. no other issues though, phone is very fast and easy to operate and battery is what to be expected on this type of phone as far as I am concerned.

VM-FEX and Nexus 1000v relation
Hi
I am a new in virtulaization world and I need to know what is the relation between Cisco Nexus 1000v and Cisco VM-FEX?, and when to use VM-FEX and when to use Nexus 1000v.
RegardsAhmed,
Sorry for taking this long to get back to you.
Nexus 1000v is a virtualized switch and as such will require that any traffic coming in or leaving the VM will first need to pass through the virtualization layer, therefore causing a minimum delay that for some applications (VMs) can be catastrophic enough that may mean too much delay.
With VM-FEX you gain the option to bypass the virtualization layer with for example "Pass-Through" mode where the vmnics are really assigned and managed by the OS, minimizing the delay and making the VMs look as if they were directly attached, also, this offloads CPU workload in the mean time, optimizing the host/VM's performance.
The need for one or the other will be defined as always by the needs your organization/business has.
Benefits of VM-FEX (from cisco.com):
Simplified operations: Eliminates the need for a separate, virtual networking infrastructure
Improved network security: Contains VLAN proliferation
Optimized network utilization: Reduces broadcast domains
Enhanced application performance: Offloads virtual machine switching from host CPU to parent switch application-specific integrated circuits (ASICs)
Benefits of Nexus 1000v here on another post from Rob Burns:

Adapter-fex Supported VICs and Nexus Switches
HI,
I am thinking of using C220M4 in standalone mode. I have been reading about adapter-fex and I am wondering which Cisco VIC supports adapter-fex and which Nexus Switch will support adapter-fex.
I am thinking of using a VIC1225 and Nexus 3000.
Thanks.I believe that adaptor fex is supported only with Nexus 5k and N2k:

Nexus 5000 - Odd Ethernet interface behavior (link down inactive)
Hi Guys,
This would sound really trivial but it is very odd behavior.
- We have a server connected to a 2, Nexus 5000s (for resiliancy)
- When there is no config on the ethernet interfaces whatsoever, the ethernet interface is UP / UP, there is minimal amount of traffic on the link etc. E.g.
Ethernet1/16 is up

- As soon as I configure the link to be an access port, the link goes down, flagging "inactivity" E.g.
sh int e1/16

- This behavior is seen on both 5Ks
- I've tried using a different set of ports, changed SFPs, and fibre cabling to no avail
- I can't seem to understand this behavior?! In that, why would configuring the port cause the link to go down?
- If anyone has experience this before, or could shed some light on this behavior, it would be appreciated.

SheldonI had identical issue
Two interfaces on two different FEXes were INACTIVE. I have two Nexus 5596 in vPC and A/A FEXes.
I also use config-sync feature.
Very same configuration was applied to other ports on other FEXes and they were working with no problems.
interface Ethernet119/1/1
inherit port-profile PP-Exchange2003
I checked VLAN status associated with this profile and it was active (of course it was, other ports were ok).
I solved it by removing port profile from this port and re-applied it... voila, port changed state to up!
Very very strange. -
Nexus 5000 vpc and fabricpath considerations
Hello community,
I'm currently in the process of implementing a fabricpath environment which includes Nexus 5548UP as well Nexus 7009
NX OS on N5K is 6.0(2)N1(2)
Regarding the FP config on the N5K I wonder what is the best practice for the peer-link. Is it necessary to configure the Portchannel like below:
interface port-channel2
description VPC+ Peer Link
switchport mode fabricpath
spanning-tree port type network
vpc peer-link
There are several VLANs configured as FP.
As I understand we can remove the command:
spanning-tree port type network
Can anyone confirm this ?
Also I noticed a "cosmetic" problem. On two port 1/9 and 1/10 on both N5K it isn't possible to execute the command "speed"?!
When the command speed is executed I receive the following error:
ERROR: Ethernet1/9: Configuration does not match the port capability
Also please notice after the vPC and FP configuration we don't do a reload!
Thanks
UdoHi Simon -
Have done some testings in the lab on ISSU with FEXes either in Active/Active and Straight-through fashion, and it works.
Disabling BA on N5K(except the vPC peer link) is one of the requirements for ISSU .
In a lately lab testing with the following topo, BA is configured on the vpc 101 between the N5Ks and Cat6k. We have a repeated regular ping between the SVI interfaces of c3750 and Cat6K.
c3750
||
vPC
||
N5K =====vPC====== N5K
||
vpc 101
||
Cat6k
When we changed the network type to disable BA, we observed some ping drops, which around 20-30.
I am not sure what your network looks like, hopefully this will give you some ideas about the ISSU. As a general recommendation, schedule a change window for some changes or even ISSU.
regards,
Michael
