  18. Microsoft SCVMM Networking Concepts Logical Networks Network Sites VM Networks Port Classification IP-Pools

  19. Logical Network Logical Network represents a network with a certain type of connectivity characteristics (for eg. DMZ network, intranet, isolation) Microsoft SCVMM Networking Concepts Logical Networks and Network Sites San Jose Seattle Host3 Host6 Host5 Host1 Host4 Host2 Network Site Network Site Network Site VM VM VM VM VM VM VM VM VM VM VM VM VM VM VM VM VM VM An instantiation of a Logical network on a set of host-groups (for eg. hosts in a POD) is called a Network Site

  20. Microsoft SCVMM Networking Concepts Virtual Machine Networks VMs are Connected to VM-networks; these can be backed by either VLANs or other overlay mechanisms (e.g. NVGREsegments). The first release of the Cisco Nexus 1000V Switch only supports VLAN-backed VM-networks.

  21. Microsoft SCVMM Networking Concepts Port-Classifications Forwarding Capture Filtering VNICs Extensible vSwitch Bundling of profiles from each extension is the port-classification VM VM VM VM PNICs

  22. Choose network VM Network VM Subnet is tied to the Network (1:1) Choose IP address type Can be dynamic (DHCP) or statically assigned Choose IP pool for static IPs Choose Port Profile Classification Policy (QoS, Security, Monitoring) A Classification refers to a Port Profile Microsoft SCVMM Networking Concepts Associating VMVNICsto VM Networks & Port-classifications

  23. Microsoft SCVMM Networking Concepts Logical Network ‘DMZ’ Putting everything together Port-profiles Servers Guests Clients VMNetwrk:DMZ_Pod1_Subn1 DMZ_Pod2_Subnet1 VM VM VM VM VM VM VM Network Site ‘DMZ_POD2’ Network Site ‘DMZ_POD1’ DMZ_Pod2_Subnet2 VMNetwrk:DMZ_Pod1_Subn2 VMNetwrk:DMZ_Pod1_Subn3 DMZ_Pod2_Subnet3 IP-Pool4 IP-Pool5 IP-Pool6 IP-Pool1 IP-Pool2 IP-Pool3 Application Server Privileged Client Intranet Client Guest Access

  24. Cisco Nexus 1000V Terminology

  25. Defining “Network sites” and “VM Networks” Logical network “DMZ” # logical-network DMZ ….. # network-segment-poolDMZ_POD1 ….. # network-segment DMZ_POD1_SUBNET1 switchport mode access switchport access vlan20 ip-pool DMZ_POD1_Pool1 network-segment-pool DMZ_POD1 # network-segment DMZ_POD1_SUBNET2 switchport mode access switchport access vlan21 ip-pool DMZ_POD1_Pool2 network-segment-pool DMZ_POD1 # network-segment DMZ_POD1_SUBNET3 switchport mode access switchport access vlan22 ip-pool DMZ_POD1_Pool2 network-segment-pool DMZ_POD1 Network Site “DMZ_POD1” VM Network DMZ_POD1_SUBNET1 VM Network DMZ_POD1_SUBNET2 VM Network DMZ_POD1_SUBNET3

  26. Networks and Profiles are Two Different Things Different ports need different protection on the same network Network Segments and Port Profiles Port-profiles Clients Guests Servers Intranet VM VM VM VM VM VM VM Network Segment Application Server Privileged Client Intranet Client One network, multiple profiles for access Guest Access

  27. And many networks can share the same protection requirements Network Segments and Port Profiles Port-profiles Clients Clients Clients Guests Guests Guests Servers Servers Servers Tenant C Intranet Tenant B Intranet Tenant A Intranet VM VM VM VM VM VM VM VM VM VM VM VM VM VM VM VM VM VM VM VM VM Application Server Privileged Client Intranet Client Guest Access Multiple networks use the same profiles

  28. Defining Port-profiles Application Network (VLAN 10) Application Clients Application Servers VM VM VM VM Cisco Nexus 1000V for Microsoft Hyper-V Cisco Nexus 1000V for VMware vSphere # network-segment application-network switchport mode access switchport access vlan 10 # port-profile application-client switchport mode access switchport access vlan 10 ip port access-group applicatoin-client in no shut state enabled # port-profile applicatoin-client ip port access-group application-client in no shut state enabled # port-profile intranet-server switchport mode access switchport access vlan 10 ip port access-group application-server in no shut state enabled # port-profile application-server ip port access-group application-server in no shut state enabled
