• Configuration of uplinks FC UCS

  Hello

  I'm confused on the configuration of the UCS CF uplinks.

  the configuration is the following UCS (2 fabric interconnects - 2 different VSAN)--> Nexus 5 k (2 for redundancy - each FI for Nexus one)--> EMC storage

  I have connected 2 ports CF since the interconnection fabric expansion module to the Nexus 5 K

  I'm confused about the configuration on the port in the nexus 5 K?

  Interconnection of fabric is in Normal mode (not switch mode), how do I configure my port on the nexus? What a F port? should I activate NPV on nexus?

  is - good port of EMC storage as F port (on nexus)?

  I'm still new to FC connectivity.

  I appreciate if you can include a configuration nexus 5K model

  Thank you

  The N5K should be mode Switch FC (in front of the NPV mode).  The FI will be NPV (aka host FC end Mode).

  On the N5K interfaces uplink FI both the EMC connection interfaces will be in mode F.  You must ensure that NPIV is enabled on the N5K (simple change without interruption).  Each FC on your N5K port must be assigned to the appropriate VSANS.  Don't forget to create the VSAN on UCS and the N5Ks respectfully.

  The FC interfaces between the UCS and the N5K must be in the same VSAN (except if you use VSAN trunking) or they will not come to the top.  For even if you want to create a channel of Port CF you do on both sides of the link.

  Once your links are pointing upwards, you need your zoning and masking on the table - including a whole other subject.

  Kind regards

• UCS in switch mode

  Hello

  It is supported to connect 3 third-party servers to the fabric of interconnections in a UCS in the switching mode?

  Is the switch in UCS mode fully supported (even if not preferred)?

  Thank you

  Even if its switching mode "called" she should not be considered a switch.  It is an interconnection fabric and intended to connect only the servers Cisco and storage 3rd party devices.   You must understand if we said that it is 'ok' to fix any ethernet device it would open valves to a lot of problems of support for the system.

  I hope that if you can afford a UCS you can allow you an additional switch to connect your 3rd - party servers or just replace with UCS servers all together ;-)

• Prevent the vlan 1 on an uplink in UCS

  People,

  I have 2 areas of disjoing and I use the new UCS 2.1 feature to allow only some VLAN on a port channel. But what I notice is that there is no way to prevent the vlan 1 to sink on this channel port on the side of the UCS, even if I'm not in the VLAN Manager.

  Any thoughts would be much appreciated.

  VLAN 1 can always on your links rising regardless of the leaking L2 configuration.  It is one of the small system.   This is called in the configuration guide:

  http://www.Cisco.com/en/us/docs/unified_computing/UCS/SW/CLI/config/Guide/2.0/b_UCSM_CLI_Configuration_Guide_2_0_chapter_010100.html#concept_4E7BF4F5FA754183B5FE3298755800A1

• UCS < 1.4.2b >, N1K and uplink

  Hi all

  I have a UCS (cluster) connected in vPC mode to a Nexus 7010.

  UCS 4.1U1 VMware ESXi, N1K with EHM PC blade-based UCS NIC is 71KR.

  Question is what happens if the two uplink of interconnection fails? I mean maybe cut fibres or stuff like that. N1K channel will be still two active link?

  Maybe the redundancy is performed by re arping for finding a mac (i've got UCS in switch mode) address, but I'm not sure. I saw a feature in the new version for a link status tracking rising full failure handling system (how?).

  last question about redundancy... what happens if a UCS IOM resets? I have some traffic disruption?

  TNX

  Dan

  Dan,

  Just to be clear, check the following:

  -UCS in switch mode

  -Adapters M71KR

  -N1k using Mac-pinning (I guess)

  -Connectivity upstream of each FI is a VPC to a pair of N7Ks.

  In this case, the N1K has no visibility of uplinks UCS.  See all your hosts VEM are two uplinks for each host (a session each fabric interconnect.)  If one of the two uplinks fails on interconnection, traffic will be the uplink remaining on this FI re-hairpin.  If the TWO uplinks on a financial institution fail, then UCS will be down (called the link at the bottom) server links and traffic should be routed through the MEC is another uplink will the other.  You can change this behavior to follow links to Server (for local switching only) but the default action of UCSM's close links to corresponding server if there are no links available on a financial institution.   Make sense?

  Now, in the last version of N1K here (1.4) is a new feature called followed by the State of the network (NST) for use with VPC - HM (such as Mac pinning).  This feature will allow to test the connectivity of a VLAN sends a probe packet and expect to get fired on another group of liaison rising/sup.   If you have a network VLAN which SHOULD be identified, you can follow with TSN.  If the network becomes unavailable, you can choose to close the uplink and re - route traffic to an another uplink.  This is useful to detect failures beyond the first jump (which would be the interconnections) as a failure somewhere in your N7K level or beyond.

  Setup Guide: http://www.cisco.com/en/US/partner/docs/switches/datacenter/nexus1000/sw/4_2_1_s_v_1_4/interface/configuration/guide/n1000v_if_5portchannel.html#wp1284321

  White paper: https://communities.Cisco.com/docs/doc-20657

  Order code: http://www.cisco.com/en/US/docs/switches/datacenter/nexus1000/sw/4_2_1_s_v_1_4/command/reference/n1000v_cmds_t.html#wp1295608

  For your last question about a failure/reset of the IOM, the cards corresponding to each blade will lose connectivity.  This is redundancy at the host level comes into play to reroute traffic.  In the case of your hosts N1K VEM, they would simply be re - route traffic on the access road to functional IOM of the chassis.

  Another point to consider is the M71 and M81 adapters support Fabric Failover.  He is tilting at the adapter level if there is a failure with any device between the adapter and uplink (like the IOM or FI).  Fabric failover is a configurable option adapter which re - will route traffic in Menlo ASIC adapters to the fabric in the 'other', such that the host will NOT see one of the two ports down.  Without switch fabric, a failure of a MOI or FI consider the adapter and this port would descend.  FF only adds a level of redundancy in the adapter without having to rely on any OS host grouping/failover.  M51KR, M61 KR and M72KR adapters do NOT support this feature.

  Kind regards

• without uplinks in dvSwitch created by UCS vCSA 6.0, 6.0u1b, 6.0u2 Manager

  I try to configure passthru vnic UCS in vCenter Server Appliance 6.0u1b. I had:

  1. updated my UCS field for the 2.2 version (6f).
  2. installed VMware-VCSA-all - 6.0.0 - 3343019.iso;
  3. installed ESXi 5.1 with the latest updates and cisco-vem-v151 - 5.1 - 1.1.1.1.zip;
  4. moved this 5.1 to vCenter ESXi host;
  5. exported vCenter extension of UCS Manager;
  6. any succesfully extension to vCenter;
  7. created vCenter, Datacenter, folder and DVS in the UCS Manager;

  After a few moments UCS created this DVS in vCenter. When I try to move 5.1 ESXi host at this DVS, there is no uplinks:

  

  VCenter then unable to bind ESXi vmnic for anything whatsoever. In addition, I tried to add an ESXi host to DVS without uplinks and obviously it worked. For example, it is a screenshot of vCenter Server Appliance 5.5 in the same window of uplinks. Servers is B200-M4 with VIC 1340 adapters to the chassis with modules e/s 2208XP. Is it possible to install vnic passthru vCSA 6.0u1b and ESXi 5.1/5.5 Server blades Cisco UCS?

  This is a bug of the vmware vsphere web 6.0 client, 6.0u1b, 6.0u2 and maybe later versions. It can not find or just cannot display the uplinks in ucs-associated distributed switch. so I could not add the host to the switch via vmware vsphere client web. uplinks in switch is very good, so this bug have several workaround solutions. host can be added to the distributed switch ucs related through:

  1. application of VMware vsphere client. It will automatically assign first free uplink in the switch and i/o directpath will work;
  2. profiles of the host. in this case I can attribute any any vmnic uplink as I want. This can be done in vsphere client of web as application of vmware vsphere client.
  3. client VMware console or sdk. I did not tried this case, but I guess it will work fine.

• N1K & UCS - B

  Hi all

  i've got blade UCS with n1k as Geraldine with a mac channel PIN.

  Now, I want to force all the IFC vMotion has preference for UCS fabric so that vMotion traffic's not going outside the UCS.

  can I do it in a port-profile (vMotion one) or should I do in vEthernet interface created by n1k?

  TNX

  /Danilo

  N1K allows preferencing of PIN in the vethernet port profiile.  Since version 1. 4A and later you can now set the "order" of failover subgroups.

  E.g.    Let's say you want to do a traffic engineering and keep your Console/management of traffic services & Vmotion traffic pinned to separate uplinks.  We know that we can use the sticky PIN to force these virtual interfaces to separate the uplink for the sup group interface, but what happens when there is a failure with one of these links?  Previously, when a member of the sup group failed with pinned interfaces it would dynamically repinned of alternately for other operational members.  New functionality has been added to force the order including backup subgroups will be used.

  To specify subgroups of failover, you can use the following command pin in the vEth interface or Port profile level.

  1000V(Config-if) backup pin ID

  So let's say that we had four vmnic uplink between 0 and 3.  We want to keep our traffic management and vmotion separate if possilbe.

  vmnic0 = subgroup ID 0 (primary for management)

  vmnic1 = subgroup ID 1 (mangement secondary, tertiary for vmotion)

  vmnic2 = subgroup ID 2 (secondary for vmotion, management further education)

  vmnic3 = group ID 3 (primary for vmotion)

  Our profiles of port could look like this.

  profile system uplink ethernet port type

  VMware-port group

  switchport trunk allowed vlan 1-3967, 4048-4093

  switchport mode trunk

  Automatic channel-group on mac - pinning

  no downtime

  System vlan 10, 3001-3002

  enabled state

  management profile-port type vethernet

  VMware-port group

  no downtime

  switchport mode access

  switchport access vlan 10

  System vlan 10

  enabled state

  pinning of backup id 0 1 2

  profile port vethernet vmotion type

• LACP group does not work with stacked 2 DELL PC 6248 and ESXi 2 5.5

  I would like to use LACP/LAG in vSphere 5.5. So I created a new vDS and a group LAG. 2 NICs per host should be used for this. We use 2 hosts, so the total 4 ports are involved. Basically, you can refer to a diagram at vmwares KB article 2051826 (http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2051826)

  It's only 2 lacp group links are active, then the other 2 are inactive. Active is the only one of the esx hosts, it depends on which ports are going to be active first.

  Any advice? Someone at - it a config like this works?

  Best regards

  Thanks to the good support at DELL.

  The secret is that you must create a separate group on the switch for each esx host. On the side of esx, you have the config with group a lacp/gal. But on the side of the switch, you need 2 groups for two guests. VMware should have this more clear I think.

• Trouble seeing vhba of UCS on Nexus 5 k

  I have UCS > 6100 (a/b) > nexus 5 k (a / b) > emc vnx 5300.  I have two installed VSAN and my switch can see two ports on my vnx5300 with show flogi. However, my 5ks don't see the vhba on the ucs system. I have two vhba configured, a tissue in one and the other for fabric b. From now the nexus is connected to the 6100 as a port channel. Ports-channel is configured as a trunk. Now, this makes me think that this is where the vsan communication is a failure. The connection to the 6100 and nexus needs to be something more than a simple trunk?

  Dennis

  Dennis,

  I hope that you give on the Fiber Channel uplinks to your N5K and not Eth/FCoE (there no FCOE Multihop yet).

  Assuming that you have your 6100's with CF logs to your N5Ks and the N5K "npiv' enabled, you should see the flogi to your host vHBAs.

  The CLI of 6100 you can also 'connect nxos' and 'show flogi npv' which will show you the CF sessions between your 6100 and N5K - I find where you problem.

  All of your SAN connections would travel on the module of Fibre Channel 6100, up to Channel N5K Fiber module, then to your table.  You can always trunk and channel ports SAN your rising FC.  Just to confirm that this is what you did and not using uplink Ethernet to your N5K waiting to work.

  Can you provide a diagram or a detail the exact topology (Eth, FC etc)

  Kind regards

• UCS connection to the existing network fabric

  Hello

  I'm trying to get some new equipment:

  2 - chassis with 4 blades of each

  2 6248UP

  1 - C240G - x 2 agile

  2 - 3750 x 10gig expansion.

  Currently, I have 3750's in a battery and intend to add these new 3750's existing battery. Can I connect the 10 g on the 3750 x directly to the fabric of interconnection to bring my new equipment into my existing network?  I thought that this would be considered UCS Uplink Ethernet Ports.

  The reason why I ask, I didn't know that I could not connect servers other than Cisco (IBM with 10 g cards) directly on the fabric and caused my second guess.

  Thank you.

  Hi mjensen

  Fabric interconnection ports are 10 GB interfaces, then Yes, you can connect to the Cisco 3750 Switch via 10Gig ports.   The only thing you want to make sure is that when plug you these devices in transceivers for use based on both ends. If you want to know the list of radios supported on the UCS 6248 take a look at the link below.

  Supported transceivers

  http://www.Cisco.com/c/en/us/TD/docs/unified_computing/UCS/HW/6200-insta...

  You're right about UCSM you want to configure these ports Uplink Ethernet ports!

  Now, the reason why you can not just plug another server ucs to the fabric of interconnection as you IBM server, because the interconnection of fabric does not work like a regular switch.   Only one UCS server can be managed via the GUI UCSM.

  Please let me know if it helps.

• How can I configure my Airport Extreme in Bridge mode (use the 3rd party router)?

  Data sheet:

  Airport Extreme - v 7.7.7

  Luma Surround Wifi 8

  I recently bought a wifi (luminance) surround system.  It comes with 3 routers that you place around your home.  Unfortunately I still have stains died in my house I'm looking to add my Airport Extreme (AE) to Luma network.  Is it as simple as plug the AE to the network (via Ethernet) and the bridge mode selection in the configuration of EI?

  I can see the AE of my iMac, and it is green.  How do you know that actually extend the wifi of my router Luma range?

  I searched the forum and all messages dealing with this are several years old.

  Thanks for your time...

  Basically, you want to create a mobile network with your Luma and AirPort Extreme routers. As you said, the extreme would need to be connected to the luminance by Ethernet and reconfigured as a bridge.

  In addition, the following are also required on the extreme:

  • Wireless mode: create a wireless network
  • The network name must be the same as that used by the Luma.
  • The type of wireless security and the password must match that of the luminance as well.

  To 'know' that the extreme extends the network of Luma, simply consult the BSSID value in the drop-down of OS X Wi - Fi. It must match the ID of the airport on your base station. Note: You must hold down the option key before clicking on the icon of the free Wi - Fi connection.
