Port assignments for the cluster and management switches
The port assignment tables provide the recommended port assignments from the
cluster and management switches to the controllers.
Management switch port assignments
Use the management port assignment table as a guide for setting up a
management switch while configuring your cluster. Port assignments can change
based on the size of your switch. In this section, a 16 ports management switch is
used as an example.
Management switch port assignment table
In a 16 port management switch configuration, ports 1 through 12 are treated
equally as cluster node interfaces. They require spanning-tree to be enabled. There
are several options for connecting the nodes to the management switch: single
management, redundant management (two connections from each node), and
RLM/BMC connections. The specific ports used as management ports are
platform- and configuration-dependent.
For redundant management configurations, each node has a logical interface (LIF)
composed of two ports; one connected to each switch. In this configuration,
depending on the number of nodes in the cluster, the RLM/BMC for the nodes
may need to utilize ports on other site switches.
This table shows an example of the port definition for a pair of 16 port
management switches with a single management connection.
