• UCS and L2 multicast issues

  Hello

  I have 2 data centers connected through a tissue of spine / sheet using BGP EVPN. In a domain controller, I UCS and other legacy Dell ESX servers connected to catalyst switches. These are shared resources via a VPC local 9 k leafs to interconnect with the fabric. Some of VLANS have L2 multicast running. All the VLANS relevant are bridged through the fabric and presented to UCS/ESXi. When virtual machines have been vmotioned overall everything has worked well except the multicast broke. I created a policy of multicast in UCS and activated the interrogator with an IP address in one of VLAN relevant from the cisco documentation what UCS will not pass traffic unless there is a mrouter/interrogator. Then, I joined politics to the Vlan relevant under the section of LAN. However still does not. I don't see any questioning on the directly connected switches information upstream is. Should applicant IGMP allowed on switches?

  Thank you!

• Upgrade of CUCM 7.1.5 to 9.1 (contract No. UCS and ESW)

  Hello

  We have CUCM 7.1.5 cluster (two servers) without contract UCS and ESW.

  What would be the better and way cheaper to upgrade to CUCM 9.1.

  We intend to use our VMWare system and only buy the CUCM 9.1 software (not servers).

  The current DLU is trensfered or should we buy everything from scratch.

  Kind regards.

  Demont - my friend, how have you been? I hope you do well!  Very nice to see you

  always help others - keep it! (+ 5)

  Kasper,

  As my friend that Demont said accurately, you contact your partner Cisco Channel/Account Manager. I just wanted to add, you can migrate DLU, but like with CUCM9, you have only UCL or CUWL - according to the type of license you select UCL/CUWL, you will need to purchase additional licenses and buy the UCS. But having said that you can benefit from Cisco in the car at 9 and can buy this at a really discounted price. Your Cisco representative can explain all the options in detail.

  Thank you

• UCS and storage network

  I am using iSCSI with the software iSCSI adapter in ESXi as well as of the UCS and use binding to ports to bind each vmkernel iSCSI port to a specific vmnic and I use 2 vmnic.  Must I also within the UCS links each vmnic so that vmnic1 traffic to cross a 1 interconnection fabric and the movement of vmnic2 fabric crossbar Interconnect 2?

  Must I also within the UCS links each vmnic so that vmnic1 traffic to cross a 1 interconnection fabric and the movement of vmnic2 fabric crossbar Interconnect 2?

  A vEth can only come out in a unique fabric of interconnection - it's decided when you take the fabric (A or B) for the vNIC. There is no additional connection to perform.

• VM ESXi and Cisco's UCS and EMC without a question of a novice

  I'm confused about the places where to install ESXi 5.0. This is on a windows Server or UCS blades if you have blades of the UCS and EMC San

  I know that we must install vcenter, a first round upward on the Cisco UCS blades. Do I connect EMC San?

  How to set these at all? I need a tutorial step by step for these 3 types of equipment to set up.

  Thank you!

  You can install any OS on blades, it's simple as console for all blades connected with the network and storage, it requires knowledge networking and storage configuration Cisco blades. Each blade has a remote as ILO or DRAC console, you can mount ISO image and start to install the OS, according to the needs we can configure boot from the local disk or boot from SAN, engineer of the UCS who has enough knowledge will create profiles of service for a whole different requirement for Windows Server and Citrix Xen server or ESXi servers , each requirement will be have the profile, just add blades and card service profile to access the console Blade Server, please download UCS virtual device and confiure and start learning.

• Port-channel problem between fabric Interconnect and vPC N7K

  Hi all

  I have a problem with the Port Uplink channel between fabric interconnect with N7K using vPC

  It's my network for the UCS deployment topology

  

  N7K I configured vPC for red link and green linkto the fabric Interconnect A I has configured the Port-Channel with Member is Port 1 and Port 2, uplink is red link. Interconnection fabric B, I have configured the Port-Channel with Member's Port 1 and Port 2, uplink's green link.

  The interface port-channel on N7K show is good, each port-channel upwards and have all members. But the fabric Interconnnect, when I see in the UCS Manager, the status of the Port-Channel on Fabic A and fabric B dysfunction not more info: no operational Member. Although all the link is a link to the top and I've got the status of the Port Channel is enabled in the UCS Manager. When I see the properties Port 1, Port to Port-Channel 2, I see the number of members status is: individual. This means channel port is not up and no member in this configuration. I want to using the port-channel load balance and more bandwidth for the uplink of 20Gig. I don't understand why?

  Please help me solve this problem, I have to send the screenshot of UCS Manager when I show the status of the Port-Channel and Port-member in port-channel to reach items.

  Can someone help me solve this problem, thanks a lot. References, please include elements for more details on the fault.

  Thank you

• UCS and QoS

  Hello:

  The ecosystem of the UCS relies on a solution of aggregation of port to the i/o chassis, namely, FEX modules.

  The FEX modules are not fully featured switches. Nor do they have a political intelligence transfer at all. Instead, the FEX modules deploy approach "pinned" in which the descenders (those facing NIC in the Server Blade, LOM, mezzanine cards) are mapped to an uplink port (those who face a 6100 Interconnect fabric) to form what can be described as a group of aggregator.

  The result is a simplified approach to blade i/o in which traffic patterns are predictable and failover is deterministic. In addition, there is no need to configure STP because ports are sent in order to exclude any possibility of a loop connection.

  This having been said, there is some merit to the argument that this port aggregation design places a hole in the middle of a deployment of QoS for the scheduling of packets on the uplink to the 6100 of interconnection fabric ports is not done in a way that recognizes the priority?

  In order to develop a little more, one can have a VMware deployment and use NetIOC or maybe configure QoS on a 1000v switch (which uplink ports are mapped to a port on the VIC de Palo) and configure QoS on the VIC and then the 6100 Interconnect fabric. But, given that the FEX is not planning for traffic to the 6100 interconnection fabric on a priority basis, the deployment of QoS has a hole in the Middle, so to speak.

  Thoughts?

  Hello

• UCS and multicast

  I'm looking for some direction on two questions of the ucs as it relates to the multicast and 6200 fabric interconnects.

  1 - Igmp v3 and igmp snooping configuration

  2 - Configuration of modules e/s and fabric goes to support the follow-up to link such that if a channel of uplink port of the IOM from uplink FI or FI runs aground, it would the vswitch uplink bear appropriate in the low not of 'black hole' packages.

  Is there a specific document that covers these?

  See, for example. https://communities.Cisco.com/thread/37174

  V2.1 added additional features of IGMP (see attachment)

• Please tell me how to connect with FCoE mini-UCS and Nexus N5k (N5K-C5548UP-B-S32)

  I have UCS 5108 chassis of Server Blade (with two blades B200 M3 inside and two FI 6324) connected to the switch of Nexus N5k 4x10GE links.

  I want to set both aggregated channels FCoE (vFC) of chassi to pass.

  All the instructions I've seen mention that UCS-mini needs to be mode end-host FC, but version 3.0 UCSM does not support this mode, what should you do?

  I put in place following the www.cisco.com/c/en/us/support/docs/switches/nexus-5000-series-switches/116248-configure-fcoe-00.html instructions

  But after the installation, I get an error on the fabric: FCoE or FC uplink is down on Vsan 500;

  And the Nexus program: Vsan 500 is declining (pending flogi)

  When I ' display interface vfc 1 ' CLI nexus I don't see "Trunk VSAN (high)", but

  "VSANS trunk (boot) (500).

  Unfortunately, I can't find the technical notes for mini UCS (with UCSM v. 3.0), so maybe you can promt guides or suggestion for this?

  Thank you in advance!

  Same question here.

• SKUs recovery Cisco UCS and expired ESW

  I have a client who has expired ESW, but still the UCS. I got the word that there is a recovery sku (L-REINST-UWL-STD), but is not in the CCW. Anyone can shed some light on this?

  I suggest that you take a look at the v9 OG CUWL, you will need to use the highest level SKU:

  L CUWL-MISC

  I just tested it and it works

• Nexus 1000v, UCS, and Microsoft NETWORK load balancing

  Hi all

  I have a client that implements a new Exchange 2010 environment. They have an obligation to configure load balancing for Client Access servers. The environment consists of VMware vShpere running on top of Cisco UCS blades with the Nexus 1000v dvSwitch.

  Everything I've read so far indicates that I must do the following:

  1 configure MS in Multicast mode load balancing (by selecting the IGMP protocol option).

  2. create a static ARP entry for the address of virtual cluster on the router for the subnet of the server.

  3. (maybe) configure a static MAC table entry on the router for the subnet of the server.

  3. (maybe) to disable the IGMP snooping on the VLAN appropriate in the Nexus 1000v.

  My questions are:

  1. any person running successfully a similar configuration?

  2 are there missing steps in the list above, or I shouldn't do?

  3. If I am disabling the snooping IGMP on the Nexus 1000v should I also disable it on the fabric of UCS interconnections and router?

  Thanks a lot for your time,.

  Aaron

  Aaron,

  The steps above you are correct, you need steps 1-4 to operate correctly.  Normally people will create a VLAN separate to their interfaces NLB/subnet, to prevent floods mcast uncessisary frameworks within the network.

  To answer your questions

  (1) I saw multiple clients run this configuration

  (2) the steps you are correct

  (3) you can't toggle the on UCS IGMP snooping.  It is enabled by default and not a configurable option.  There is no need to change anything within the UCS regarding MS NLB with the above procedure.  FYI - the ability to disable/enable the snooping IGMP on UCS is scheduled for a next version 2.1.

  
  
  This is the correct method untill the time we have the option of configuring static multicast mac entries on
  
  the Nexus 1000v.  If this is a feature you'd like, please open a TAC case and request for bug CSCtb93725 to be linked to your SR.
  
  This will give more "push" to our develpment team to prioritize this request.
  Hopefully some other customers can share their experience.

• Masking vs. zoning for UCS and NetApp storage LUNS

  I know it's more a matter of Cisco MDS/storage, but nobody knows masking the LUNS and zoning, which one would be the most preferred method? I have two switches Cisco fabric 9148, two controllers SAN Netapp FAS3210 1 UCS chassis with 4 blades B200 M2. I said that I should not connect the Cisco UCS fabric interconnect directly at the back of the NetApp SAN and configure with LUN masking, but I rather configure a fabric zoning on switches Cisco 9148 MDS. Normally, this wouldn't be a problem but we have an offsite location where we have not all DMS switches to, and I would like to connect them directly to the San.

  I was told that this could lead to corruption if misconfigured dsik and point of view of Cisco is to use a zoning by some type of switch Cisco Fabric. Of course, I have of course this Cisco advises anyone to manage this type of configuration through their facilities instead of on the SAN. Does anyone have an opinion on the matter?

  Zoning and masking are two completely different characteristics.

  Zoning occurs on your storage switches and is the equivalent of an ACL (Access Control List).  It limits who may be considering other targets and/or initiators.  (Who I see?)

  Occurs on your storage array and masking limits what initiator LUN has access to.  (What do I see?)

  * UCS is not supported to directly connect a storage array in the interconnection of fabric, at least to have a storage upstream switch (MDS or equivalent) to push the zoning.  The use of zoning prevents a faulty initiator potentially impacting on the operation of the others by limiting what they can see in the fabric.

  If you happen to have a Nexus 5 K by chance, they can also work as your storage switch.  The N5K is able to perform almost all of the same services as MDS fabric and is fully supported.

  Kind regards

• The review of the UCS and VCP

  Hi all

  I do not have a secure Channel and yet so I will at least make the test of the UCS?

  Is-Cisco has a system as they will allow us to test of the UCS, but they will not give us unless we are SECURE.

  Thank you

  Ismail

  Hi Ismail

  You can always take the test and still qualify as a Cisco Unified Computing Technology Specialist of the design and a Cisco Unified Computing Technology Support Specialist without a PCV.

  But if you're after Cisco Data Center Unified Computing Support Specialist, etc. then yes VCP is always a pre - req (I heard that there will be rejected in favour of a managed Cisco equivalent, but who is without merit)

  Unfortunatley (that I found) just passing examination VCP wasn't enough, but the VMware course is also a mandatory requirement for VCP VMware.

  Good luck with it.

• UCS and VMWare-VNIC-VMNIC active-active/active-standby

  Dear team,

  We have 3 ESXi hosts each vSwitch1 and portgroup with the name TEST with 50 of VLAN
  We have 3 Configuration of virtual machines with 19.168.0.X series and are assigned to the VLAN TEST

  Each vSwitch1 is assigned with 2 vmnic on the same VLAN 50 (from UCS vNIC, service profile - where in 1 vnic comes from the fabric and other fabric B)

  (1) inter-VM communication will work if we do an active Vmnic and other relief

  Inter 2) VM communication may work some time or may not work if we do the two active vmnic

  The above behavior is the same for virtual machines in combination with ESXihosts, expect if these virtual machines are on the same host ESxi interVm communication works very well...

  What setting to do if we do get active vmnic and always inter-VM communication

  NB:

  As mentioned above these vNIC is created from the UCS Service profile, where, in 1 vnic comes from the fabric and other fabric B, and when we try the standby active mode the interVm communication works and even when we FI's down, the standy adapter automatically rises and traffic goes well

  Thanks and greetings

  Jose

  Same condition still - the link between the FI and FI B does not serve for any traffic data. So if your source is the use of FI and your destination is on FI B, then the traffic has to go through the switch upstream. If you are still not sure, have active vmnic0 on a host computer and vmnic1 as active on the other host - communication will not take place (assuming that they go to different financial institutions)

  The solution to your problem is to define VLAN 50 of upstream network. If you don't want to do that, then you must limit all traffic within the same IF (definitely not recommended).

  Thank you

• Emulator of the UCS and Fibre Channel (PCI Passthrough)

  Hello

  I would like to know if anyone of you knows if emulator UCS supports CF communications and how to configure them.

  I have 2 PCI Fibre Channel interfaces on the host Hardware and I applied PCI Passthrough on the ESXi hypervisor. It works with other virtual machines.

  Thank you very much

  No, unfortunately not.
