Defect ID: DEFECT000324848
Technical Severity: High
Summary: Any 8G blade or 8G switch running with FOS 6.4.0, 6.4.0a, 6.4.0b, 6.4.0c and 6.4.1 could
observe a loss of connectivity on a port or trunked ISL causing all traffic entering the switch
or the blade to be dropped.
Symptom: When there is a trunk consisting of 2 or more ports, other ports on the same ASIC chip are
improperly programmed with the same table entry in ASIC routing table as trunk ports. .
Customer observes symptom such as frame rejects on trunked ISLs for SCSI commands
when a host on a different port in the same ASIC reboots. The defect will also only affect 8G
platforms and 8G blades. 4G blades inserted into a DCX or DCX-4S are not affected, but 8G
blades inserted into a Brocade 48000 can be affected.
Feature: Field Escalation
Function: FC Layer 2 Routing
Probability: Medium
Found in Release: FOS6.4.0
Where Else Fixed: FOS6.4.1 a
Defect ID: DEFECT000325021
Technical Severity: High
Summary: C3 (Class 3) frame discards due to destination unreachable are incremented when
supportshow/supportsave command is run after a fastboot.
Symptom: SCSI timeout may be seen on the following platforms: Brocade300, 5300, 7800 and 8G
embedded platforms during supportsave. There is a very small number of frames dropped
and most of the time, the server will retry SCSI traffic and will not experience any functional
impact.
Feature: Field Escalation
Function: ASIC Driver
Probability: Low

bounce without any packet loss occurring in the IP network.
Feature: FCIP
Function: FCP TCP/IP Stack
Probability: High
