Brocade VDX Ethernet interfaces
The Brocade VDX compact switches have a single configurable Ethernet interface, Eth0, which can be
configured as a management interface.
The modular chassis, the Brocade VDX 8770-8 and the Brocade VDX 8770-4, have two redundant
management modules, MM1 and MM2. Each management module can communicate with each of the
line cards (interface modules) through an Ethernet connection. Each management module has two
Ethernet interfaces, Eth0 and Eth2.
Eth0 is the management interface and can be configured with an IP address. Eth2 provides connectivity
to the other management module and the line cards in the chassis. The Eth2 IP addressing scheme
uses default IP addresses to communicate between the modules; these addresses are not user-
configurable.
To set a virtual IP address for the chassis, use the chassis virtual-ip command in RBridge ID
configuration mode.
Lights-out management
Lights-out management (LOM) is the ability for a system administrator to monitor and manage servers
by a LOM remote control program.
A complete LOM system consists of a hardware component called the LOM module and a program that
facilitates the continuous monitoring of variables such as microprocessor temperature and utilization.
The program also allows for such remote operations as rebooting, shutdown, troubleshooting, alarm
setting, fan-speed control, and operating system reinstallation.
The modular chassis, the Brocade VDX 8770-8 and the Brocade VDX 8770-4, have two redundant
management modules, MM1 and MM2. Each management module can communicate with each of the
line cards (interface modules) through an Ethernet connection. Each management module has two
Ethernet interfaces, Eth0 and Eth2. These interfaces are also known as Out of Band (OoB)
management interfaces and support LOM programs.
Stateless IPv6 autoconfiguration
IPv6 allows the assignment of multiple IP addresses to each network interface. Each interface is
configured with a link local address in almost all cases, but this address is only accessible from other
hosts on the same network. To provide for wider accessibility, interfaces are typically configured with at
least one additional global scope IPv6 address. IPv6 autoconfiguration allows more IPv6 addresses, the
number of which is dependent on the number of routers serving the local network and the number of
prefixes they advertise.
When IPv6 autoconfiguration is enabled, the platform will engage in stateless IPv6 autoconfiguration.
When IPv6 autoconfiguration is disabled, the platform will relinquish usage of any autoconfigured IPv6
addresses that it may have acquired while IPv6 autoconfiguration was enabled. This same enabled and
disabled state also enables or disables the usage of a link local address for each managed entity
(though a link local address will continue to be generated for each switch) because those link local
addresses are required for router discovery.
The enabled or disabled state of autoconfiguration does not affect any static IPv6 addresses that may
have been configured. Stateless IPv6 autoconfiguration and static IPv6 addresses can coexist.
