400 IBM z13s Technical Guide
11.3.1 Network planning for the HMC and SE
Plan the HMC and SE network connectivity carefully to allow for current and future use. Many
of the z Systems capabilities benefit from the network connectivity options that are available.
For example, these functions, which depend on the HMC connectivity, are available to the
HMC:
Lightweight Directory Access Protocol (LDAP) support, which can be used for HMC user
authentication
Network Time Protocol (NTP) client/server support
RSF through broadband
HMC access through a remote web browser
Enablement of the SNMP and CIM APIs to support automation or management
applications, such as IBM System Director Active Energy Manager (AEM)
Security: Configuration of network components, such as routers or firewall rules, is
beyond the scope of this book. Whenever the networks are interconnected, security
exposures can exist. For more information about HMC security, see z Systems Integrating
the Hardware Management Console‘s Broadband Remote Support Facility into your
Enterprise, SC28-6951. It is available on IBM Resource Link.
