Considerations for the Brocade 8000
3
Port trunking and QoS features
Because the Brocade 8000 has limited available buffers and port trunking and QoS require more
buffers than normal, consider the following points:
• Do not enable QoS by itself on more than six Fibre Channel ports at a time. If you attempt to
enable QoS on more than six ports, the Brocade 8000 may enter buffer-limited mode.
• To enable both trunking and QoS on the Brocade 8000, it is recommended that you enable
QoS first. If you enable trunking first, both features will compete for buffers and you will not be
able to enable QoS on more than two ports. If you enable QoS first, adequate buffers will be
available for trunking due to the function of QoS.
Managed Fabric Name Monitoring mode
Managed Fabric Name Monitoring (MFNM) mode is enabled by default on the Brocade 8000.
However, you can disable or enable this policy at any time. Enabling or disabling MFNM on one port
group enables or disables it for the entire switch. RASLOG messages are generated only if MFNM is
enabled on the entire switch and multiple fabrics are connected to the switch.
Fabric OS command support
This section describes how Fabric OS commands are supported on the Brocade 8000 in AG mode.
• The following commands are not supported on the Brocade 8000 in AG mode:
- ag --pgmapadd
- ag --pgmapdel
- ag --persistentalpaenable
- ag --printalpamap
- ag --deletepwwnfromdb
