DATA CENTER CONFIGURATION GUIDE
Configuring an iSCSI SAN Using Brocade FCX Switches 22
Rate Limiting
iSCSI traffic can generate bursts of heavy traffic that can be mistaken as traffic storms. The Brocade FCX
provides ability to limit these storms on the switch, but in dedicated iSCSI SANs, as being configured
through this document, this feature should not be enabled. By default, this feature is disabled which is why
there is no need to enter any additional commands.
Syntax: [no] broadcast limit <num>
Syntax: [no] multicast limit
Syntax: [no] unknown-unicast limit
The iSCSI SAN is now ready for deployment. The iSCSI SAN we just created is dedicated for iSCSI traffic only.
Any port on the switches can be used for an iSCSI initiator or an iSCSI target. As the users connect initiators
and targets to the switches, it is always best to distribute the load evenly across the network by distributing
the load across different switches and different switch ports.
SWITCH CONFIGURATION DUMP
This section shows a sample output of the running-config from a Brocade FCX stack configured per the
instructions in this guide. Use this information to help validate or troubleshoot your configuration. The IP
addresses and interfaces used in this example may differ from your configuration.
