Four-node cluster connected to a switch pair without VLT
In this topology, an LACP port channel is used to connect the two switches.
The commands in the following sections are run to complete the configuration of both switches. The port
numbers used in the configuration commands correspond to those shown in Figure 13.
Note: The commands in the tables below should be entered in the order shown. All commands are provided
in the file attachments named S5048F-1A-no-vlt.txt and S5048F-1B-no-vlt.txt.
7.2.1 General settings
Configure the hostname, OOB management IP address and default gateway. Specify an NTP server
accessible by the switch. Enable LLDP for troubleshooting. Enable RSTP as a precaution against loops.
Configure S5048F-Leaf1A as the primary RSTP root bridge using the bridge-priority 0 command and
S5048F-Leaf1B as the secondary RSTP root bridge using the bridge-priority 4096 command.
