Rsf Is Broadband-Only - IBM z13s Technical Manual

Note: Generally, use 1000 Mbps/Full duplex.

11.3.4 TCP/IP Version 6 on the HMC and SE
The HMC and SE can communicate by using IPv4, IPv6, or both. Assigning a static IP
address to a SE is unnecessary if the SE communicates only with HMCs on the same subnet.
The HMC and SE can use IPv6 link-local addresses to communicate with each other.
IPv6 link-local addresses have the following characteristics:
Every IPv6 network interface is assigned a link-local IP address.
A link-local address is used only on a single link (subnet) and is never routed.
Two IPv6-capable hosts on a subnet can communicate by using link-local addresses,
without having any other IP addresses assigned.
11.3.5 Assigning addresses to the HMC and SE
An HMC can have the following IP configurations:
Statically assigned IPv4 or statically assigned IPv6 addresses
Dynamic Host Configuration Protocol (DHCP)-assigned IPv4 or DHCP-assigned IPv6
addressees
Auto-configured IPv6:
– Link-local is assigned to every network interface.
– Router-advertised, which is broadcast from the router, can be combined with a Media
Access Control (MAC) address to create a unique address.
– Privacy extensions can be enabled for these addresses as a way to avoid using the
MAC address as part of the address to ensure uniqueness.
An SE can have the following IP addresses:
Statically assigned IPv4 or statically assigned IPv6
Auto-configured IPv6 as link-local or router-advertised
IP addresses on the SE cannot be dynamically assigned through DHCP to ensure repeatable
address assignments. Privacy extensions are not used.
The HMC uses IPv4 and IPv6 multicasting
Diagnostic Information task can be used to identify the IP addresses (IPv4 and IPv6) that are
being used by the HMC to communicate to the CPC SEs.

For a customer-supplied switch, multicast must be enabled at the switch level.
