Fabric OS v6.4.1 Release Notes v1.0 Page 33 of 62

• It is recommended that for directors with more than 300 E_Ports, the switch be disabled

prior to executing the “switchCfgTrunk” command (used to disable or enable trunking on

the switch).

• During non-disruptive firmware upgrades, E_Ports in R-RDY mode may cause some frame

drops on the E-port links.

• The portCfgFillWord

portCfgFillWord command, applicable to 8G-capable ports, has been enhanced with

FOS v6.3.1 and v6.4 to provide two new configuration options (Modes 2 and 3). The

available settings include:

Mode 0 – IDLE/IDLE

Mode 1 – ARBF/ARBF

Mode 2 – IDLE/ARBF

Mode 3 – If ARBF/ARBF fails use IDLE/ARBF

Although this setting only affects devices logged in at 8G, changing the mode is disruptive

regardless of the speed the port is operating at. The setting is retained and applied any

time an 8G device logs in. Upgrades to FOS v6.3.1 or v6.4 from prior releases supporting

only modes 0 and 1 will not change the existing setting, but switches or ports reset to

factory defaults with FOS v6.3.1 or v6.4 will be configured to Mode 0 by default. The

default setting on new units may vary by vendor. Please use portcfgshow CLI to view the

current portcfgfillword status for that port.

Modes 2 and 3 are compliant with FC-FS-3 specifications (standards specify the

IDLE/ARBF behavior of Mode 2 which is used by Mode 3 if ARBF/ARBF fails after 3

attempts). For most environments, Brocade recommends using Mode 3, as it provides

more flexibility and compatibility with a wide range of devices. In the event that the

default setting or Mode 3 does not work with a particular device, contact your switch

vendor for further assistance.

• For the configure command, in FOS v6.4, the default value that displays for Maximum Logins per

switch is different than the value that displays in FOS v6.3.x. The default value has not changed; it

was displayed incorrectly in FOS v6.3.x, and is now corrected.
