VG350 Uplinks

Has anyone had any experience connecting a VG350 to a switch stack?  I see that there's an option to create a port-channel, but I can't configure the interfaces with the "channel-group" command.  Ideally I'd like to have a cross-stack etherchannel (layer 2) with layer 3 connectivity to a loopback interface; regardless I'd like to have a redundant solution in place.  In theory we could utilize a BVI but that's not a road I want to go down right now.
Any suggestions are appreciated.

I ended up connecting the interfaces back to the stack via L3 connections then injected my loopback address into the routing process.  It's not the straight L2 connection I wanted but it works.

  • Various questions on uplink profiles, CoS, native VLAN, downlink trunking

    I will be using vPC End Host Mode with MAC-pinning. I see I can further configure MAC-Pinning. Is this required or will it automatically forward packets by just turning it on? Is it also best not to enable failover for the vnics in this configuration? See this text from the Cisco 1000V deployment Guide:
    Fabric Fail-Over Mode
    Within the Cisco UCS M71KR-E, M71KR-Q and M81KR adapter types, the Cisco Unified Computing System can
    enable a fabric failover capability in which loss of connectivity on a path in use will cause remapping of traffic
    through a redundant path within the Cisco Unified Computing System. It is recommended to allow the Cisco Nexus
    1000V redundancy mechanism to provide the redundancy and not to enable fabric fail-over when creating the
    network interfaces within the UCS Service Profiles. Figure 3 shows the dialog box. Make sure the Enable Failover
    checkbox is not checked."
    What is the 1000V redundancy?? I didn't know it has redundancy. Is it the MAC-Pinning set up in the 1000V? Is it Network State Tracking?
    The 1000V has redundancy and we can even pin VLANs to whatever vNIC we want. See Cisco's Best Practices for Nexus 1000V and UCS.
    Nexus1000V management VLAN. Can I use the same VLAN for this and for ESX-management and for Switch management? E.g VLan 3 for everything.
    According to the below text (1000V Deployment Guide), I can have them all in the same vlan:
    There are no best practices that specify whether the VSM
    and the VMware ESX management interface should be on the same VLAN. If the management VLAN for
    network devices is a different VLAN than that used for server management, the VSM management
    interface should be on the management VLAN used for the network devices. Otherwise, the VSM and the
    VMware ESX management interfaces should share the same VLAN.
    I will also be using CoS and Qos to prioritize the traffic. The CoS can either be set in the 1000V (Host control Full) or per virtual adapter (Host control none) in UCS. Since I don't know how to configure CoS on the 1000V, I wonder if I can just set it in UCS (per adapter) as before when using the 1000V, ie. we have 2 choices.
    Yes, you can still manage CoS using QoS on the vnics when using 1000V:
    The recommended action in the Cisco Nexus 1000V Series is to assign a class of service (CoS) of 6 to the VMware service console and VMkernel flows and to honor these QoS markings on the data center switch to which the Cisco UCS 6100 Series Fabric Interconnect connects. Marking of QoS values can be performed on the Cisco Nexus 1000V Series Switch in all cases, or it can be performed on a per-VIF basis on the Cisco UCS M81KR or P81E within the Cisco Unified Computing System with or without the Cisco Nexus 1000V Series Switch.
    Something else: Native VLANs
    Is it important to have the same native VLAN on the UCS and the Cisco switch? And not to use the default native VLAN 1?   I read somewhere that the native VLAN is used for communication between the switches and CDP amongst others. I know the native VLAN is for all untagged traffic. I see many people set the ESXi management VLAN as native also, and in the above article the native VLAN (default 1) is setup. Why? I have been advised to leave out the native VLAN.
    Example:Will I be able to access a VM set with VLAN 0 (native) if the native VLAN is the same in UCS and the Cisco switch (Eg. VLAN 2)? Can I just configure a access port with the same VLAN ID as the native VLAN, i.e 2 and connect to it with a PC using the same IP network address?
    And is it important to trunk this native VLAN? I see in a Netapp Flexpod config they state this: "This configuration also leverages the native VLAN on the trunk ports to discard untagged packets, by setting the native VLAN on the port channel, but not including this VLAN in the allowed VLANs on the port channel". But I don't understand it...
    What about the downlinks from the FI to the chassis. Do you configure this as a port channel also in UCS? Or is this not possible with the setup described here with 1000V and MAC-pinning.
    No, port channel should not be configured when MAC-pinning is configured.
    [Robert] The VSM doesn't participate in STP so it will never send BPDU's.  However, since VMs can act like bridges & routers these days, we advise to add two commands to your upstream VEM uplinks - PortFast and BPDUFilter.  PortFast so the interface is FWD faster (since there's no STP on the VSM anyway) and BPDUFilter to ignore any received BPDU's from VMs.  I prefer to ignore them then using BPDU Gaurd - which will shutdown the interface if BPDU's are received.
    -Are you thinking of the upstream switch here (Nexus, Catalyst) or the N1kV uplink profile config?

I have been advised to leave out the native VLAN.[Robert] The native VLAN is assigned per hop.  This means between the 1000v Uplinks port profile and your UCS vNIC definition, the native VLAN should be the same.  If you're not using a native VLAN, the "default" VLAN will be used for control traffic communication.  The native VLAN and default VLAN are not necessarily the same.  Native refers to VLAN traffic without an 802.1q header and can be assigned or not.  A default VLAN is mandatory.  This happens to start as VLAN 1 in UCS but can be changed. The default VLAN will be used for control traffic communication.  If you look at any switch (including the 1000v or Fabric Interconnects) and do a "show int trunk" from the NXOS CLI, you'll see there's always one VLAN allowed on every interface (by default VLAN 1) - This is your default VLAN.Example:Will I be able to access a VM set with VLAN 0 (native) if the native VLAN is the same in UCS and the Cisco switch (Eg. VLAN 2)? Can I just configure a access port with the same VLAN ID as the native VLAN, i.e 2 and connect to it with a PC using the same IP network address?[Robert] There's no VLAN 0.  An access port doesn't use a native VLAN - as its assigned to only to a single VLAN.  A trunk on the other hand carries multiple VLANs and can have a native vlan assigned.  Remember your native vlan usage must be matched between each hop.  Most network admins setup the native vlan to be the same throughout their network for simplicity.  In your example, you wouldn't set your VM's port profile to be in VLAN 0 (doens't exist), but rather VLAN 2 as an access port.  If VLAN 2 also happens to be your Native VLAN northbound of UCS, then you would configured VLAN 2 as the Native VLAN on your UCS ethernet uplinks.  On switch northbound of the UCS Interconnects you'll want to ensure on the receiving trunk interface VLAN 2 is set as the native vlan also.  Summary:1000v - VM vEthernet port profile set as access port VLAN 21000v - Ethernet Uplink Port profile set as trunk with Native VLAN 2UCS - vNIC in Service Profile allowing all required VLANs, and VLAN 2 set as NativeUCS - Uplink Interface(s) or Port Channel set as trunk with VLAN 2 as Native VLANUpstream Switch from UCS - Set as trunk interface with Native VLAN 2From this example, your VM will be reachable on VLAN 2 from any device - assuming you have L3/routing configured correctly also.And is it important to trunk this native VLAN? I see in a Netapp Flexpod config they state this: "This configuration also leverages the native VLAN on the trunk ports to discard untagged packets, by setting the native VLAN on the port channel, but not including this VLAN in the allowed VLANs on the port channel". But I don't understand it...[Robert] This statement recommends "not" to use a native VLAN.  This is a practice by some people.  Rather than using a native VLAN throughout their network, they tag everything.  This doesn't change the operation or reachability of any VLAN or device - it's simply a design descision.  The reason some people opt not to use a native VLAN is that almost all switches use VLAN 1 as the native by default.  So if you're using the native VLAN 1 for management access to all your devices, and someone connects in (without your knowing) another switch and simply plug into it - they'd land on the same VLAN as your management devices and potentially do harm.What about the downlinks from the FI to the chassis. Do you configure this as a port channel also in UCS? Or is this not possible with the setup descrived here with 1000V and MAC-pinning.[Robert] On the first generation hardware (6100 FI and 2104 IOM) port channeling is not possible.  With the latest HW (6200 and 2200) you can create port channels with all the IOM - FI server links.  This is not configurable.  You either tell the system to use Port Channel or Individual Links.  The major bonus of using a Port Channel is losing a link doesn't impact any pinned interfaces - as it would with individual server interfaces.  To fix a failed link when configured as "Individual" you must re-ack the Chassis to re-pinn the virtual interfaces to the remaining server uplinks.  In regards to 1000v uplinks - the only supported port channeling method is "Mac Pinning".  This is because you can't port channel physical interfaces going to separate Fabrics (one to A and one to B).  Mac Pinning gets around this by using pinning so all uplinks can be utilized at the same time.--[Robert] The VSM doesn't participate in STP so it will never send BPDU's.  However, since VMs can act like bridges & routers these days, we advise to add two commands to your upstream VEM uplinks - PortFast and BPDUFilter.  PortFast so the interface is FWD faster (since there's no STP on the VSM anyway) and BPDUFilter to ignore any received BPDU's from VMs.  I prefer to ignore them then using BPDU Gaurd - which will shutdown the interface if BPDU's are received.-Are you thinking of the upstream switch here (Nexus, Catalyst) or the N1kV uplink profile config?[Robert] The two STP commands would be used only when the VEM (ESX host) is directly connected to an upstream switch.  For UCS these two commands to NOT apply.

  • VNICs (both uplinks and VM's vNIC) are blocked on N5K DVS after upgrading to ESXi 5.1

    Hello Gents,
    I cought into weird situation after upgrade VMware ESXi 5.0 to 5.1 on UCS C200M2. Before upgrade I have had server with configured static adapter-fex VNICS and floating/dynamic vm-fex interfaces working perfectly in DirectPathIO mode for VMs. Initial deployment was done according Cisco N5K VM-fex operation guide for   NX-OS 5.1(3)N1(1). There were vCenter 5.1, 2xN5K and 2xC200M with ESXi 5.0 integrated so that N5K DVS was brought to vCenter and hosts could be added to DVS. One of C200M2 (still on ESXi5.0) has no problem while operating VM-Fexs and adapter-fexs while part of its uplinks are on VSS and othe part on DVS (in fact there are none VMs on VSS, so all the workloads use DVS).
    But upgraded C200M cannot operate with DVS correctly: any vmks, vm networks, VMs connected to DVS lose network connectivity.
    Attached picture illustrates diag of connectivity status (uplinks/ets are blocked).
    VEM are fresh and running:

    Do anybody have an idea why it is going wrong?

    Of course they exist.There is unpatched server with ESXi 5.0 near upgraded server and it works perfectly.
    Finally I downgraded server to ESXi5.0 again and VM-FEX functionality restored.

  • No sound in Uplink (x86_64)

    Hi,
    I've installed Uplink from aur (uplink package) and it was patched to 1.55. When I run it I don't have any sound at all. I tried to install it manualy, but when I try to run the original version I get a black screen and normal music (I believe I can click something, but I can't see what). I'm a bit confused.

    "Mix_OpenAudio error: No available audio device" - this looks interesting, AFAIR Uplink uses SDL. I have sound in other SDL apps. I've tried export SDL_AUDIODRIVER="esd" and "oss" or turn off pulseaudio, no luck.
    I use 64-bit, my sound is OSS and PulseAudio.
    I tried to use windows version with wine, but I also have no sound when using the 1.54 or 1.55 patch. What is weird is that the version without a patch has normal sound with wine.
    Can anybody give me a clue where should I begin? I tried to find anything (this is why I got so far - it involved installing a lot of new libraries in my system), but unfortunately no solution to my problem.

  • Best Practice for vDS, Uplinks and TF ?

    Hi,
    Three questions about vNetwork Distributed Switch:
    My environment:
    - Datacenters: 2
    - Hosts: 50 (25 in each datacenter)
    - Cluster: 10 (5 in each datacenter) (2 to 5 nodes per cluster)
    - Nics Hosts:
         - 1 nic for management
         - 1 nic for redundant management and VMotion
         - 2, 4 or 8 nics with trunk internal networks (15 VLANs)
         - 2, 4 or 8 nics with trunk to external networks (10 VLANs)
         - 1 nic for backup
         - Over 1500 vms
    Question 1 - Speaking only of internal, external and back up, how I should have vDS?
    - 6 vDS (2 internal, 2 external and 2 backup, half in Datacenter), right?
    Question 2 - I have clusters of different sizes, some clusters have two hosts nic for internal networks while others cluster hosts have 4 or 8 nics nics, so I must have DvUplinks how many in each vDS? What is the impact of having uplinks without nic attached in some clusters?
    - VDs_Internal = 8 uplinks?
    Question 3 - What is good practice to use Teaming and Failover in this case? "Routed originating based on virtual port" or "Routed bases on physical NIC load" knowing that I'm not using Network Control IO?
    thanks,
    Reis

    Q1. With VLAN you can also use a single vDS with several portgroup (and for some, like FT, vMotion, ... use explicit uplink order).
    Q2. This could be a little problem. With vDS you can map uplink to pNIC... but DRS (for example) could not know if your host has less uplinks. If the difference is minimal go with a single cluster, otherwise consider to use 2 clusters.
    Q3. The virtual port solution could be simple and good in most cases.

  • Why the Fibre uplink ports are down state even after giving no shutdown command at the interface

    Hi
    My Predecessors brought 2 CISCO 3750 switches and implemented LACP on these core switches. Due to looping in the network the Fibre uplink ports GigabitEthernet1/1/3 and GigabitEthernet2/1/3 are down (I think these uplink ports are mirrored in the LACP concept)
    Please see below from the configuration.
    I logged into the core switch and went to this particular interface GigabitEthernet1/1/3 and I gave the following command and still the port is in the down state after I gave no shutdown command. Do I need to give the same no shutdown command at interface GigabitEthernet2/1/3 as well ?
    Switch-Core1(config) interface GigabitEthernet1/1/3
    Switch-Core1(config-if)#no shutdown
    Switch-Core1(config-if)#

    It is possible you are overloading that little 4215. If that is the case you should also be seeing "missed packet percentage" messages in your events.
    How much traffic is your 4215 getting? Those sensors will start to drop packets for inspection at about 30 Mb/s.

  • How to connect a 6120XP to Cat3560 Uplink Eth Switch?

    Hi guys,
    I have a question the company has bought a 5108 Chassis,6 B-200 M2 blades and 2 6120XP for our test lab.But i need to know that how can i connect my 6120XPs to the Cat 3560 for uplink ethernet?
    I tried to use that SFP GigPort on the 3560 but it didn't respond.I think i need to know what kind of SFP+ trancievers or which models do i have to use.
    Thanks.
    BR from Istanbul

    The first 8 ports on the 6120 FI supports GE SFPs. Please see the following link Table 2:
    http://www.cisco.com/en/US/prod/collateral/ps10265/ps10276/data_sheet_c78-524724.html
    Table 3 of the above link has all the supported GE SFPs. SFP's part number starts with GLC is supported on the 3560s.

  • WRT54G v5 Uplink Port Not Designated

    Running out of ethernet ports, wanting to add a Fast Switch (SMCGS5), the back panel of this router doesn't designate which port is an uplink port, likewise the switch. Unless I went blind, my User Guide and the User Guide online for this model, has no mention of any uplink port designation, other than the 3rd paragraph of the online Product Description, for this model.
    I'm currently using one laptop, two PC's, and one NAS, and want to add one more wired PC. I'm noticing intermittent stalling or freezing after I installed the switch into Port 1. So I switched over to running to the switch from Port 4, noticed no difference in wired performance. Shutdown everything to be used on the network, including doing a reset all, no change in wired performance when the switch is used, otherwise, works fine with existing router/switch ports. 
    Took switch to friends house to install in their network. They have no problems with this switch.
    Would anyone be able to help me identify if the WRT54G v5 Router even has a uplink port? Or are "all" the ports, uplink ports? I've read the pre-posting information and have searched for similar question(s).

    You can still keep your linksys router...I would recommend you to upgrade the firmware on the router , then reset and re-configure it...
    Download the firmware from here ,
    Follow these steps to upgrade the firmware on the device: -
    Open an Internet Explorer browser page.In the address bar type - 192.168.1.1
    Leave username blank & in password use admin in lower case...
    Click on the 'Administration' tab- Then click on the 'Firmware Upgrade' sub tab- Here click on 'Browse' and browse the .bin firmware file and click on "Upgrade"...
    Wait for few seconds until it shows that "Upgrade is successful"  After the firmware upgrade, click on "Reboot" and you will be returned back to the same page OR it will say "Page cannot be displayed".
    Press and hold the reset button for 30 seconds...
    Then, unplug the power cable while holding down the reset button for another 30 Seconds...
    Plug the power cable back in, and keep holding down the reset button for another 30 Seconds...
    Release the reset button...Now re-configure your router and connect it to your switch...I hope this works...

  • SCVMM Kicks out Nexus 1000V Uplink NIC Any ideas?

    The SCVMM suddenly kicks out the Nexus 1000V Uplink NIC,
    thus preventing me from remediating the change.
    Also i get this error message
    Using Hyper V as virtualization platform

    Hello,
    You can use one Ethernet port-profile with a channel-group command (like 'channel-group auto mode on mac-pinning') and assign it to all the vmnic interfaces that need to carry the same set of VLANs
    The same port-profile can be used on other hosts too. The N1k would automatically bundle (port-channel) the interfaces that belong to the same ESX host (accomplished through the 'channel-group auto' command)
    If you need the interfaces to carry separate sets of VLANs, then you need a different port-profile.
    Port-profile is just a container for a common set of configuration that you can apply for multiple interfaces across multiple hosts.
    Thanks,

  • MiFi 4510L Uplink is slow

    I use "Verizon Jetpack 4G LTE Mobile Hotspot MiFi 4510L".
    Before, I heard "Download/Uplink is 2-5Mbps, All the time, 24/7" from Verizon chat system.
    Therefore, I started use of "Verizon Jetpack 4G LTE Mobile Hotspot MiFi 4510L".
    However, the Uplink speed is 0.5Mbps when I measure the speed.
    Would someone teach me the solution of this problem?
    I want to use Skype(video) to my mother smoothly.

    A typical good 3G connection is 1-2 mbps for download and 1mbps for upload.  For most people those speeds will allow them to do whatever they need on the internet. 
    A typical 4G LTE connection is much better with 10+ mbps for download and 5 mbps on upload.  Your MiFi 4510L is 4G LTE compatible but you must be within range of this network to take advantage of those speeds.
    Check the light on the side of your MiFi.  If it is green then you are 4G, if it is purple/pink then you are 3G.  The best way to get your MiFi to perform at the normal level is to run through the various levels of resets.
    Level 1 Reset:
    Power down the MiFi
    Let the MiFi sit for 30 seconds
    Power on the MiFi
    Test the connection
    Level 2 Reset:
    Power down the MiFi
    Remove the back cover
    Remove the battery
    Remove the SIM card
    Allow the MiFi to sit for 30 seconds
    Reassemble the MiFi
    Test the Connection
    Level 3 Reset
    Power on the MiFi
    Remove the back cover
    Press and hold the Reset button next to the battery for 10 seconds
    Watch the MiFi E-Ink display to see if all the icons are displayed
    Release the Reset button
    Reassemble the MiFi
    Test your connection

  • Clearing UCS Manager fault about unused adapter uplink from C-series

    I have a number of C240M3 servers in a UCS infrastructure.  They all have two VIC 1225 adapters and when they were initially connected, the technicians accidentally connected the second adapter on some of them to the FEXs.  For now at least, we only want the first adapters used (both ports - one to each FEX).  However, since adapter 2 was connected at one point, UCS Manager won't stop giving these faults:
    F0206 - Adapter 5/2 is unreachable
    F0209 - Adapter uplink interface 5/2/1 link state: unavailable
    It doesn't seem to have a way to clear the faults without reconnecting that second adapter.  Re-acknowledging the server didn't help and I'm not sure I want to try decommissioning them and then getting them to appear in UCS again.
    Does anyone know how to manually clear these faults?

    Hi Kenny,
    Correct; the second PCIe card is not connected to a FEX anymore.  I tried reack'ing the FEXs but that didn't help, unfortunately.  (If it helps, the fault appears in the individual servers' Faults tab - the FEXs don't show any faults.)

  • Best QOS Practice for a congested Uplink Port?

    I have an MPLS uplink port to a carrier that carries both voice and data.
    For example, Customer 3750 Switch 100MB Uplink--->100MB Uplink Carrier Router---Carrier Router 6MB MLPP Voice/Data MPLS Uplink with QOS configured for Voice subnet on carrier side too.
    The port occasionally suffers from overutilizition and spikes to the full 6MB
    I have a centralized CUCM that has phones that occasionally reset due to TCP 2000 timeouts (usually during the period of high utilization)
    So that I can avoid most phone resets during high utilization I have prioritized all voice traffic (signalling and RTP streams) to EF
    My question: What is best practice configuration for a congested uplink port? I'm going to assume the answer is it depends (the all great technical answer )
    Here are my thoughts on how to configure the 3750 uplink port so far:
    apply mls qos trust dscp
    apply priority-queue out
    (Here's where I'm looking for help)
    apply some sort of policing or bandwidth statement on the interface to protect the voice traffic: What are the recommendations and what would those configurations look like?
    I would apply these these configurations to the uplink ports at the edge site as well as the central site.
    Any thoughts as to the best way to accomplish this?

    You want to prioritize VoIP traffic at congestion points, which for you, looks to be whenever your LAN bandwidth hits your 6 Mbps WAN.
    If the carrier takes your 100 Mbps, and doesn't just generally police all traffic to 6 Mbps, but instead has different priority queues for the 6 Mbps, all you should need to do, is insure you traffic is correctly processed by your WAN vendor.  This, though, might require marking your traffic for the WAN provider.
    If you carrier first polices all your traffic at 6 Mbps (many do), then you need to shape the traffic (with you own prioritization) before the provider "sees" it.  If you need to "shape" on the 3750, there's a command to limit a port's bandwidth utilization, as a percentage.  However it's not exact, so you may need to "shape" slower than 6 Mbps to insure 6 Mbps won't be exceeded.  (BTW, for 6 Mbps, if you need to do QoS, you would be better off with an ISR.)
    You also mention 6 MLPPP, but it's unlclear what your device is for that.
    How to configure 3750 QoS is involved.  Basically when you enable QoS, each port has four dedicated egress queues.  By default, different traffic markings go into one of the four queues, each queue has same share of the bandwidth, and almost same share of the buffers.  The PQ command you noted, enables the first queue to always transmit its packets first.  Normally, you'll want to do that for VoIP bearer packets, which you've (insured are) directed to that queue.  You also want to insure that VoIP signally packets are not likley to be dropped and, more or less, are forwarded quickly.
    Cisco has multiple papers on QoS configurations, including papers for 3750s, so instead of my trying to present that, the above is intended as an overview.  Feel free to post additional questions, the more specific, the more likely you'll get an answer.

  • SR-IOV Uplink Port with NIC Teaming

    Hello,
    I'm trying to setup my uplink port profile and logical switch with NIC Teaming and SR-IOV support. In Hyper-V this was easy, just had to create the NIC Team (which I configured as Dynamic & LACP) then check the box on the virtual switch.
    I'm VMM it does not seem to like to enable NIC Teams with SR-IOV:
    Can anyone advise? I'm not using any virtual ports. I just want all my VMs to connect to the physical switch though the LACP NIC Team, something which I thought would be simple.
    I have a plan B - don't use Microsoft's NIC Teaming and instead use the Intel technology to present all the adapters as one to the host. I'd rather no do this.
    Thanks
    MrGoodBytes

    Hi Sir,
    "SR-IOV does have certain limitations. If you configure port access control lists (ACLs), extensions or policies in the virtual switch, SR-IOV is disabled because its traffic totally bypasses the switch.
    You can’t team two SR-IOV network cards in the host. You can, however, take two physical SR-IOV NICs in the host, create separate virtual switches and team two virtual network cards within a VM. "
    There is really a limitation when using NIC teaming :

  • Uplink problems from UCS 6128 FI

    Hi,
    We have one demo UCS system. It was working pretty smoth, we take it to few presentations etc etc.
    Few days we cleaned system, and decided to reconfigure and deploy.
    Overview :
    Cisco UCS blade chasis, 2 b200m2 servers with VIC adapters, 2x6128 FI.
    Uplinks are only 1 Gb and GLC-T modules are used for uplinks.
    Problem now is that as soon as i configure port as uplink and configure it for 1 Gbps, port changes to admin down, and no connections to upper switches are available.
    We decided to upgrade to latest software and now is 2.0(4a). Conection from VIC, through IOM and to server ports is ok, but uplinks are still not working.
    Upper switch  c2950 has ports that connects to ucs as trunk, everything as usual.
    Just to clarfy, this exact setup was active before and working.
    Errors from UCS are :

    Any idea? Everything is connected as before, it used to work flawless.

    well, server ports are up. I know this is uplink ports problem, but really cannot see where the problem is :). Ports on northbound switch that ucs connects to are trunk ports, vlans are defined on that switch.
    I also suspect sfp's (cisco glc-t) but it seems pretty strange that 2 sfp modules are malfunctioning. They used to work pretty neat.
    Just to mention we have same UCS in production and it is working, config is same, ports are same, nxos outputs for ethernet uplinks are same..
    Just to check somenthing i created two hba's (we do have FC expansion card, but ucs is not connected to FC switches), and vif paths for FC are up...seems that this is releated to ethernet problem solely.
