= Specifying Port Offsets
Configure port offsets with {brandname} servers when running multiple instances
on the same host. The default port offset is `0`.

Use the `-o` switch with the {brandname} CLI or the
`infinispan.socket.binding.port-offset` system property to set port offsets.

For example, start a server instance with an offset of `100` as follows. With the default configuration, this results in the {brandname} server listening on port `11322`.
