The UI tier nodes must be able to reach the Cache tier nodes directly for ServAssure NXT Upstream Spectrum Sessions. You can configure Ansible at installation to ensure that the UI tier nodes can reach an alternate request IP on the Cache tier nodes when they have multiple interfaces/IPs. The default IPv4 or IPv6 address is used when there is no configuration.
Example
This example shows how to edit the
[nxt_engine] group to supply the request IP address of the Cache tier node.
[nxt_engine]
my.server.hostname.1 jetty_request_ip=10.0.0.1
my.server.hostname.2 jetty_request_ip=10.0.1.1
NOTE: When configuring NAT'd addresses,
ensure that the UI tier nodes are able to reach TCP addresses (port 8181), and
the NAT rules are configured to forward this traffic to the application bound
addresses of the Cache tier nodes (Ansible does not manage NAT
rules).
