Considerations for the Brocade 8000
3
• The following commands have restricted usage, mostly because the Brocade 8000 contains
only eight Fibre Channel ports and does not support the Automatic Port Configuration policy:
- ag --pgcreate
- ag --policyenable
- ag --policydisable
- ag --portcfgdefault
• To enable or disable FCoE (F) ports, use fcoe --enable and fcoe --disable instead of portdisable
and portenable.
• The portcfgdefault command resets the degraded state and NPIV PerPort and clears the
BufferLimitedMode on a port. For other AG platforms, this command restores the port
configuration to factory default values.
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 on more than six ports, the Brocade 8000 may enter buffer-limited mode.
• To enable both Trunking and QoS on the Brocade 8000, we recommend that you enable QoS
first. If you enable Trunking first, both features will compete for buffers and you will not 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.
Automatic Login Balancing
MFNM is enabled by default on all port groups and cannot be disabled on the Brocade 8000.
Because of this, the pgsetmodes, pgdelmodes, and pgcreate commands are blocked for the -m
option, and Automatic Login Balancing cannot be enabled.
