Customer has multiple security zones in environment, and VMware vCenter is located in a Management Security Zone. VSMs in security zones have dedicated management interface facing Management Security Zone with firewall in between. What ports do we need to open for the communication between VSMs and vCenter? The Nexus 1000V troubleshooting guide only mentioned TCP/80 and TCP/443. Are these outbound from VSM to vCenter? Is there any requirements from vCenter to VSM? What's the best practice for VSM management interface configuration in multiple security zones environment? Thanks.
