Master and Slave Host heart beat ports in HA

[zeebahi]

Hi everyone.

I am trying to find heart beat port used by master/slave host in HA to detect each other liveliness.

I have been searching docs but they all explain how it works.

Any help will be appreciated!!

Thanks and have a good weekend!!

I have found thisin docs:

vSphere HA Security vSphere HA is enhanced by several security features. Select firewall ports opened vSphere HA uses TCP and UDP port 8182 for agent-to-agent communication. The firewall ports open and close automatically to ensure they are open only when needed.
