2 Caveats in v3.5.0
The following caveats relate to v3.5.0 behavior.
2.1 AAA Administration
The following caveats relate to AAA behavior.
2.1.1 Persistent Username/Password Prompt
When either
aaa authentication login default
or
aaa authentication enable default
are set to
"none", the DarkStar will continue to prompt for a username and password. Dismiss the prompts by pressing the Enter key.
2.1.2 AAA Authorization, Enable Mode, and Console Login
When database users with enable privileges log into a system via a console configured for aaa authentication and
authorization, they are not immediately enabled. After login, it is necessary to type "enable". When prompted for the
password, don't type anything: press the <Enter> key to continue.
2.1.3 AAA Authentication Login Default None Already Enabled
Typically, AAA authentication commands are enabled by issuing the command
aaa new-model
. However,
aaa
authentication login default none
will function without being specifically enabled, exposing your DarkStar to
unauthorized access.
2.1.4 Repeated Login Attempts
Repeated login attempts may cause RADIUS accounting packets to be missing the relevant user id.
2.1.5 AAA authentication
When AAA authentication is not required, username and password prompts still appear; however, authentication is not
performed.
2.2 Amplifiers
The following caveat relates to amplifier behavior.
2.2.1 Wrong EDFAs Settings when a 4-band or 6-band filter is used in DMD-A
In v3.5.0 for a DMD-A system, the input EDFA(s) will not be set to the correct output power value if a 4-band or 6-band filter is
installed in the system. DXMOS incorrectly uses the 96-channel filter insertion loss numbers in calculating the EDFA power
settings. This results in a setting for the input EDFA(s) that is too high.
Note:
The insertion loss for the 4-band and 6-band filter
is much less than that of the 96-channel filter.
The work-around for this issue is to manually set the input EDFA(s) in the DMD-A rather than using the
path input
channel-count
command. In other words, use the
control output power
command instead of the aforementioned
path
command. Contact XKL Customer Support for details on what the optimal power setting should be for your system.
Note:
The optical power setting is dependent on the number of DWDM channels in your system.
