Release Notes for the Passport 8600 Release 3.7.6
• Nortel Networks does not recommend using the CLI command
trace level 4 4. This command, which provides some very low-level
information about chassis manager tasks, can impact the overall behavior of
the system. (Q00896409)
• Any I/O Module that comes up as faulty on the master CPU is not
synchronized to the backup CPU. All configurations associated with this I/O
board are also not synchronized between the master and the backup CPU.
(Q00890882)
• Nortel Networks does not support the 8691omSF with the Passport 8600
Series Switch Software Release 3.7.6. (Q00909840-01)
• When a POS port is disabled and then enabled, STP is disabled or enabled
according to the BCP state. If BCP was enabled and STP was disabled, then
STP becomes enabled after a port is reset (because BCP was enabled). In this
scenario, you need to manually disable STP. (Q00281408)
• On bootup or after a CPU failover, the following error message may appear:
ERROR Task=tChasServ RTC update on standby CPU failed!
It has no negative impact on your switch. (Q00527144)
• After setting the
max-mac-count command for a port, the switch incorrectly
allows you to change this value to one that is less than the current mac count.
(Q00850159-01)
• Although the copy and cp commands perform the same function, there are
some minor differences: the
copy command does not allow wildcard
characters and does not display acknowledgement that the copy was
successful; the
cp command allows wildcard characters and displays
acknowledgement that the copy was successful. (Q00785080)
• 8608 Gigabit ports may not initialize if there is an ASF 5112 Firewall
connected to any of the ports. This same issue may occur if there is a port
connected to other Alteon products, such as the Alteon 184 or 180e. The
workaround is to disable AutoNegotiation on the Gigabit ports of both the
Passport 8600 and the Alteon switch. (Q00538075)
• Disabling the Telnet daemon prevents any connection between the master and
backup CPUs using the Telnet
peer command. (Q00595763-04)
• Do not enter illegal or illogical IP addresses in the
/etc/hosts filename.
The existence of illegal IPs causes problems with address and hostname
resolution. (Q00914252)
• Even if VLAN tagging is not enabled, the copper gigabit Ethernet ports accept
and respond to VLAN tagged packets.
