Figure 8 Fastfabric Tools
3.4.1 Chassis setup
This option helps the user to manage or monitor the chassis like setting up the Out-of-Band IP address on
the switches, configuring syslog server, configuring NTP server, setting up time zone, OPA node description,
rebooting the chassis, configuring the fabric manager, viewing firmware version, etc.
3.4.2 Switch setup
This can be used to retrieve firmware information, update firmware, and generate switch reports to aide in
debugging. Additionally this allows running commands in parallel across all switches, as well as rebooting
them.
3.4.3 Host Setup
This can be used to setup password-less SSH between hosts, upgrade the OPA software, configure IP over
Fabric, running a command in parallel on all the hosts, etc.

are listed as follows:
Subnet Manager (SM)
 Subnet Manager usually assigns Local Identifiers (LIDs) to each port connected to the fabric
 Manages the routing table of the fabric
 Link and port initialization
