Hi everyone, one clarification...: when we set-up a VMM integration (VMWare AVS, or Kubernetes), which multicast address we can use for "Fabric-wide multicast"? Have to be different from "bridge domain multicast address (GIPo)"? Or have just to be different from "Pool of Multicast Addresses"?   Thanks in advance Roberto ... View more

Hi everyone, regard ACI and Kubernetes Integration, when we deploy the  Kubernetes VMM domain with acc-provision we have option to choise to use VXLAN or VLAN as encap_type used by OPFLEX.   Questions: Which is the best practice or suggested option to use? If we decide to use VLAN pool, I suppose them have to exists between leaf and openvswitch container running on the host. In this case we will have one subinterface on linux host for each vlan? If yes, we need a new interface or it is possibile to use the same used for infra? And in case, will this subinterface be created during the addition of annotation? ... View more

Hi everyone, I have some problem with KVM InBand access to UCS b-series server. I have configured all things that are needed to access via InBand management access.

Hi everyone, I have just one doubt regarding the data-group range for OTV. In some documentations I read that I have to configure the data-group range to be part of a SSM multicast address; while in other document seems that I can configure a ASM as well. For example in this configuration guide I read that I can configure even a ASM multicast group address: Cisco Nexus 7000 Series NX-OS OTV Configuration Guide You should configure IGMP version 3 on both sides of the join interface link. The OTV edge devices send IGMP (S,G) joins to the edge devices in other sites in the same VPN. If you must configure IGMPv2, you must configure the last-hop router to do an ssm-translate, and the data-group range for the overlay interface must be SSM. Edge Device 1 interface ethernet 2/1 ip address 192.0.2.1/24 ip igmp version 3 no shutdown vlan 5-10 feature otv otv site-identifier 256 interface overlay 1 otv control-group 239.1.1.1 otv data-group 239.1.1.0/29 otv join-interface ethernet 2/1 otv extend-vlan 5-10 no shutdown And in this other documentation I read that I must configure the data-group as SSM: Nexus 7000 - OTV - Design and Configuration Example Ensure that provider / WAN network supports IP Multicast. For IP Multicast, ASM / Bidir need to be supported for control plane communication and SSM for any data multicast traffic between sites. !STEP 1: feature otv !STEP 2: interface Overlay1 !STEP 3: interface Ethernet1/9 ip igmp version 3 !STEP 4: otv join-interface Ethernet1/9 !STEP 5: otv control-group 239.1.1.1 otv data-group 232.1.1.0/24 !STEP 6: otv extend-vlan 110 !STEP 8: otv site-vlan 200 Could anyone help me to better understand if I have to use SSM for data-group or not?

Hello all, currently I have a network scenario with a couple a Cisco Nexus 5596UP and several Cisco Nexus 2000 (2232PP, 2248TP ecc.) connected to the parent switch (N5K) in single-homed FEX topology. Is it possible to convert the N2K from single-homed to dual-homed FEX topology without, or minimal, interruption of traffic? Thanks a lot in advance. Roberto Loiudice ... View more
