12. 12 © 2009 Cisco and VMware Data Center 3.0: Solutions to Accelerate Data Center Virtualization What is a Port-Profile?  A port-profile is a container used to define a common set of configuration commands for multiple interfaces  Define once and apply many times  Simplifies management by storing interface configuration  Key to collaborative management of virtual networking resources  Why is it not like a template or SmartPort macro? – Port-profiles are ‘live’ policies – Editing an enabled profile will cause config changes to propagate to all interfaces using that profile (unlike a static one-time macro)

13. 13 © 2009 Cisco and VMware Data Center 3.0: Solutions to Accelerate Data Center Virtualization Port Profile Configuration n1000v# show port-profile name WebProfile port-profile WebProfile description: status: enabled capability uplink: no system vlans: port-group: WebProfile config attributes: switchport mode access switchport access vlan 110 no shutdown evaluated config attributes: switchport mode access switchport access vlan 110 no shutdown assigned interfaces: Veth10 Support Commands Include: Port management VLAN PVLAN Port-channel ACL Netflow Port Security QoS Support Commands Include: Port management VLAN PVLAN Port-channel ACL Netflow Port Security QoS

14. 14 © 2009 Cisco and VMware Data Center 3.0: Solutions to Accelerate Data Center Virtualization  Administrators can interact with individual switchports, overriding a port profile  Use to isolating problems with one or two interfaces without changing the port-profile and affecting other ports  Manual configuration always takes precedence over a port profile configuration  The ‘no’ command can remove the override and restore the profile’s config by doing: n1000v(config)# int vethernet 2 n1000v(config-if)# switchport access vlan 250 n1000v(config)# int vethernet 2 n1000v(config-if)# no switchport access vlan Overriding Port Profile Configuration

15. 15 © 2009 Cisco and VMware Data Center 3.0: Solutions to Accelerate Data Center Virtualization Port Profile Inheritance  Profile inheritance allows the construction of profile hierarchies  ‘Parent’ profiles pass configuration to ‘child’ profiles  Only the child profiles need to be visible within VC  Updates to the parent filter to the child  Child profiles can be updated independently n1000v(config)# port-profile Web n1000v(config-port-prof)# switchport mode access n1000v(config-port-prof)# switchport access vlan 100 n1000v(config-port-prof)# no shut n1000v(config)# port-profile Web-Gold n1000v(config-port-prof)# inherit port-profile Web n1000v(config-port-prof)# service-policy output Gold n1000v(config-port-prof)# vmware port-group Web-Gold n1000v(config)# port-profile Web-Silver n1000v(config-port-prof)# inherit port-profile Web n1000v(config-port-prof)# service-policy output Silver n1000v(config-port-prof)# vmware port-group Web-Silver Effective Port Profile – Web-Gold Access Port VLAN 100 Gold QoS Policy Effective Port Profile – Web-Silver Access Port VLAN 100 Silver QoS Policy
