Fabric OS v6.4.1 Release Notes v1.0 Page 31 of 62
ASIC port groups are 0-15, 16-31, 32-47, 48-63, and 64-79. The routes will be broken if the port
mirror resources are spread across multiple port groups.
• Port Mirroring is not supported on the Brocade 7800 .
10G Interoperability
• 10G interop between FC10-6 and McDATA blades is not supported due to a HW limitation,
however the FC10-6 is supported in a chassis running in Interopmode 2 or 3 (FC10-6 to FC10-6
connections only). An FC10-6 blade will not synchronize with a McDATA 10G blade. However, the
inability to synchronize will not negatively impact the system
.
Port Fencing
•
The state changes counter used by Fabric Watch in FOS v6.3 has been updated to ignore any
toggling of F-ports due to planned internal mechanisms such as throttling and trunking. There are
some FOS CLI commands such as portcfgspeed, portCfgTrunkPort etc that implicitly
disable/enable ports after configuration.
• The Port Fencing feature is not supported for Loss of Sync (LOS) and Link Failure (LF) areas of
Port/F-port/E-port classes. State change area can be used in place of LOS/LF areas for Port
Fencing
.
Zoning
•
If the default zoning mode is set to All Access and more than 120 devices are connected to the
fabric, you cannot enable All Access.
•
Beginning with the FOS v6.2.0 release, all WWNs containing upper-case characters are
automatically converted to lower-case when associated with a zone alias and stored as part of a
saved configuration on a switch. For example, a WWN entered as either
“AA.BB.CC.DD.EE.FF.GG.HH” or “aa.bb.cc.dd.ee.ff.gg.hh” when associated with a zone alias will be
stored as “aa.bb.cc.dd.ee.ff.gg.hh” on a switch operating with FOS v6.2.0 or later.
This behavioral change in saved zone alias WWN members will not impact most environments.
However, in a scenario where a switch with a zone alias WWN member with upper case characters
(saved on the switch with pre-FOS v6.2.0 code) is merged with a switch with the same alias
member WWN in lower case characters, the merge will fail, since the switches do not recognize
these zoning configurations as being the same.
For additional details and workaround solutions, please refer to the latest FOS Admin Guide
updates or contact Brocade Customer Support.
ICLs
•
If a DCX with an 8-link ICL license is connected to a DCX with a 16-link license, the DCX with the
16-link license will report enc_out errors. The errors are harmless, but will continue to increment.
These errors will not be reported if a DCX with a 16-link license is connected to a DCX-4S with only
8-link ICL ports.
•
If ICL ports are disabled on only one side of an ICL link, the enabled side may see enc_out errors .
AP 7420 Interoperability (refer to Defect 307117)
• A switch running FOS v6.4 cannot connect to an E_Port on an AP7420 .
• An AP7420 can form a direct ISL connection with a switch running FOS v6.3 or lower version of
FOS firmware. A switch running FOS v6.4 can still participate in a fabric with an AP7420 as long
as the AP7420 is not directly connected to the FOS v6.4 switch.
