• UCS - san-port-channel on vpc

  Hello

  I hope someone can help with this,

  I have a Setup with 2 Nexus of 5548 connected via a link of vpc peers and a keepalive, these two nexus switch have a link of standard VPC to a 6500 upstream. It works fine,

  Then, there are several native FC connections of the 5548 to of 6248. I know that there is the possibility to configure the channel port of CF on the UCS 2.0 but it is possible to link 5548 CF interfaces in a port channel san through a vpc between the nexus of 5548.

  so, for example, I can port-channel which follows through a vpc or is a channel of port san, limited to the same nexus only switch ports.

  Fc1/31 & fc1/32 fabric sent to-> NX5K - 1 Port fc1/31 & NX5K - 2 Port fc1/32 (san port-channel 10 on a VPC)

  Fabric B fc1/31 & fc1/32 passed to-> NX5K - 1 Port fc1/32 & NXFK - 2 Port fc1/31 (san port-channel 11 on a VPC)

  Thank you

  Ray.

  It is not possible. VPC is the only Layer 2 ethernet port channel. Port channel San cannot be built through vpc

• Setting port channel between UCS - FI and MDS 9124 (Mode F)

  Dear team,

  We tried to create the channel of port between UCS FI and MDS 9124

  But the port channel do not take action in mode F on MDS 9124

  FI is in host FC end Mode

  We have allowed FC uplink on FI trunking

  We have activated NPIV on MDS

  We have activated the MDS trunk

  FI and MDS in default VSAN

  To check that we have changed the way FI FC channels mode and switch port became active, but in E mode

  When we enabled CF trunking of uplink on the port mode FI channels and FC Switching became active in mode TE

  but in both cases above, showflogi database shows WWPN of SAN alone does not have the any fi.

  How to achieve this?

  Have read that no need to change the mode switching mode of CF swicthing and keep FC Endhost way

  SO how to channel ports with mode F MDS and FI (Display Mode as NProxy)

  What is it has nothing to do with the MDS NX - OS version? (https://supportforums.cisco.com/thread/2179129)

  If yes how to put as license for ports came with the camera and we don't have any CAP/PAK or license file as she came

  with license

  Also, we saw 2 files available for download (m9100-s2ek9-kickstart - mz.5.2.8 .bin and m9100-s2ek9 - mz.5.2.8 .bin b b) to use

  Hi Jo Bo.

  What version of the software if your MDS race?

  On your UCS do connect nxos and show ficelleStringString ficelleT inteface and find the mac address.

  It is possible that you could be hitting the bug below. If this is the case, you may need to update the firmware on your MDS.

• Effect of loss of link IOM UCS on CF in Port-channel mode

  Hello

  We recently discovered that when UCS Server Ports are port-channel mode, loss of a member link causes CF traffic disruption in a VMware environment.  Host VMware never sees a path down and his guest enter a time-out period of IO wait.  Once expired the time-out of comments, a SCSI reset restores connectivity of storage.  We responded to several customers and said that this is the expected behavior.  This is of concern to us and how it affects the design decisions.

  Any contribution is appreciated.

  Thank you.

  It is true, that you expect the SCSI timeout, and then the operating system must redo a flogi. Of course, I guess that you have CF multipathing installation and work; Therefore, no disruption to traffic.

  Without port-channel, the vhba on the failing tissue will go down; and the management of multi-channel FC is the only solution.

  The PowerConnect switches do not have the ability to show as much detail as the Force10 can. The RMON tables have an interface use %, what may be the closest we can do on the PowerConnect switch.

  #show rmon statistics

  I've seen some monitoring software which was able to question the switch via SNMP and get some information of bandwidth. However, this can be a bit inconsistent, according to which switch and what software is used.

  The MIBs/OID can be downloaded with the software switch.

• 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.

• Fabric Port Channel

  Hello

  Once in production, when the addition of cables in a PortChannel from fabric between the IOM and a FI, first had to be re - ack frame? (so that we will have the chassis package downtime). Or rather, as is a Port-Channel cables are detected automatically, so that it is not necessary to re - ack, and so there is no downtime in all... one that is the correct statement?

  Thank you

• vPC and VSS port-channel uplinks

  Hello Forum team!

  Currently I have a configuration of a couple of Nexus 5548UP in a field of vPC with a couple of Nexus 2248TP aircraft in a double scenario hosted for the access layer (FEX in a vPC also). Core/distribution, there are a pair of 6509 cluster VSS. Now I configured a regular port-channel every 5K to the VSS functionality and works as expected. My question is this: given that in the vPC a 5K is the main and the other is secondary, a configurable vPC for the uplinks to the VSS instead of a channel of regular port of each 5 K?

  In addition, configurations must be replicated manually on both Nexus 5 K? I'm in denial about this. I'm used to how VSS works.

  Thanks to the advanced guys!

  Hello

  You can use a vPC of the pair of Nexus 5 K to the VSS cluster. There is a white paper Cisco Catalyst 6500 VSS and Cisco Nexus 7000 vPC of interoperability and best practices that will in this. While the white paper is for Nexus 7000 are you interested to do probably is the configuration shown in Figure 2 and so the scenario and considerations are the same.

  On the Nexus switches with vPC there are still two control i.e. plans, the primary and secondary that you mention. For all the configurations that should be applied at the primary and secondary, you can manually configure on the two switches or use the synchronization of Configuration characteristic Nexus (see Configuration synchronization Operations for more details).

  He was 15-months we have looked at the function so probably things have changed, but following issues with our tests, and we were see reported here in the forum at this time, we decided not to use the config Sync feature. Outside all bugs, there are some operational changes to consider and then make sure that you are comfortable with how config-sync works before putting it in a production environment.

• Determine the NIF port used by the HEART when it is configured in a port channel

  I recently saw an excellent video of live Cisco UCS troubleshooting performance that showed how to track traffic network within Cisco UCS. The speaker made a comment however, to determine that NIF is used by a high HEAT when port-channels are used between the FEX and FI there are different commands to run. You will need to determine the outcome of hash-load balancing. Unfortunately, he never entered what were these commands.

  Then when we have pinned port-channel instead of HIFs and NIFs veths, what commands will indicate which way is used?

  Matt,

  You can use this command:

  B (nxos) # sh port-channel - balance load< this="" will="" tell="" you="" the="" load="" balance="" method="">

  If you use source-dest-ip as in my case, you can use this command:

  B (nxos) # sh port-channel - the balance of the charge-transfer interface port-channel ID vlan ID x.x.x.x y.y.y.y dst - ip, src - ip and it will show you something like this:

  Lack of params will be substituted by 0.

  Algorithm to balance the load on the switch: source-dest-ip
  crc8_hash: 109 port id coming out: EthernetX / Y  < this="" is="" what="" you="" are="" looking="" for="">
  Param (s) used to balance the load to calculate:
  DST - ip: y.y.y.y
  SRC - ip: x.x.x.x
  DST - mac: 0000.0000.0000
  CBC - mac: 0000.0000.0000

  For the blade, depends on which the active vNIC is, for the FEX, depends on pinning, based on the server is located in the blade slot.  Strange servers go through odd links and same servers through the same ports.

  Hi Joris,

  It is a known problem and is documented as a cosmetic bug internal. Logically speaking, CDP is not supported on etherchannel interfaces and 'sh cdp port-channel' command should not be available.

  The platform of 6500, although the "port channel show cdp neighbor" returns the result, it's just for convenience and does not mean that the CDP is supported on the port channels. In fact, if you try to enable CDP on port-channel on 6500, it generates an error:

  PO1 #int 6500 (config)

  6500(Config-if) #cdp en

  % CDP is not supported on this interface, or for this encapsulation

  If you run "debug cdp events", you can see the packets exchanged on the physical interface rather than on the port-channel. Correct way is to check the neighborship of the cdp on the physical interfaces.

  See you soon,.

  Hi Mark-

  What is at the other end of the port-channel? It seems that article gi1/1/4 is the aerator with the end of the negotiation and enter a reception "on" State, while IG2/1/4 is not. They both require to be in the same State to form a beam. You can check the status with sh flowcontrol item in gi1/1/4 int for example.

  I would like to either watch to change the config on the other side or define flowcontrol get discount on the two switchports local.

• Nick partnering and Port Channel

  We have a dvSwitch with a group of ports for vmotion and the other for the management trafik.

  The dvSwitch have two physical network adapters for the uplink. The two groups of ports are done NiC team with two active cards, so each group of ports can use two network cards.

  The dvSwitch is connected to a physical switch witch is not using the channel Port.

  My question is:

  1. when I use the collection of network adapters on the dvSwitch, is a good idea to configure the physical switch Port channels to make a real balancing?

  2. is it possible to configure the channel on the physical switch Port when the esxi server is in production?

  Rather than configuring channeling of port (EtherChannel), which is supported only with the static mode 'on' (no LACP) anyway, you can consider switching to 'charge basic Teaming (LBT)' policy. For vMotion and management however - as in your question - I go ahead and set up two groups of ports as active / standby, so that each of them uses its dedicated uplink and only failover to a single connection in the case of a link failure.

• MDS configuration for port channel
