Configuring IM&P servers
To configure the IM&P servers used for remote access:

.
The resulting page displays any existing servers that have been configured.
2. Add the details of an IM&P publisher:
a. Click New.

b. Enter the IM and Presence publisher address and the Username and Password credentials
required to access the server. The address can be specified as an FQDN or as an IP address; we
recommend using FQDNs when TLS verify mode is On.
Note that these credentials are stored permanently in the Expressway database. The IM&P user must
have the Standard AXL API Access role.

d. Click Add address.
The system then attempts to contact the publisher and retrieve details of its associated nodes.
Note that the status of the IM&P server will show as Inactive until a valid traversal zone connection
between the Expressway-C and the Expressway-E has been established (this is configured later in
this process).
