Use Virtual Networking Services
Cisco Nexus 1000V Port Profiles: The Nexus 1000V extends the concept of referenced configuration through the use of Cisco NX-OS port profiles. It publishes them in the hypervisor management domain, allowing ease of assignment and the portability of networking and security policies.
Since the Nexus 1000V is a virtual distributed switch, the policies from the profiles are known and supported across Cisco vPath v2.0, a fundamental architecture component of the Cisco Nexus 1000V vPath optimizes the use of Layer 4-7 virtual networking services in virtual machine and cloud environments.
Service chaining is supported, providing multiple virtual network services as part of a single traffic flow. For example, you can simply specify the network policy and let vPath direct traffic:
- First, through the Cisco ASA 1000V Cloud Firewall for tenant edge security
- Then, through the Cisco Virtual Security Gateway for Nexus 1000V Switch for a zoning firewall
Cisco vPath also works on VXLAN to support movement between servers in different Layer 2 domains. Together, these features promote highly secure policy, application, and service delivery in the cloud.
