Release Notes
Limitations and Restrictions
The following caveats are acknowledged in release 1.3.5.x:
Problem:
On SG500XG-8F8T switches, 1000BASE-T and 100BASE-TX modes
only support frame sizes up to 9000 bytes. If the 10G copper port is configured in
the 1G or 100M mode, and oversized frames are sent, the port drops the link.
Shutting and then opening this port can bring up this port again. (CQ149642,
CSCuj46378)
the 1G or 100M mode, and oversized frames are sent, the port drops the link.
Shutting and then opening this port can bring up this port again. (CQ149642,
CSCuj46378)
Solution:
Limit frame size to 9000 bytes or less in 1000BASE-T mode.
Problem:
For the SX500 and SG500X switches, when users manually assign the
unit ID, and at the same time force units 1 or 2 to be the stack master, the unit shuts
down when the unit is reloaded. (CQ150107, CSCuj46520)
down when the unit is reloaded. (CQ150107, CSCuj46520)
Solution:
Reloading or Power cycling all units in stack will resolve the problem.
Problem:
On the SX500 and SG500X switches, when the users modify the unit ID,
and force master selection at the same time, the stack master shuts down.
(CQ150148, CSCuj38655)
(CQ150148, CSCuj38655)
Solution:
Configure the unit ID on the web GUI. Reload the stack and converge,
and then specify force master. While reloading the switch, configuring it with a
unique unit ID can recover the switch.
unique unit ID can recover the switch.
Problem:
For SX500 stacking, when the stack mode is changed from native to
basic hybrid using the command: stack basic-hybrid auto unit-id-auto reboot, and
the stack is reloaded then restarted with the default configuration, the startup
configuration file is removed. (CQ150131, CSCuj37279)
the stack is reloaded then restarted with the default configuration, the startup
configuration file is removed. (CQ150131, CSCuj37279)
Solution:
Backup startup-config file before changing the stack mode.
Problem:
When authenticating using WBA, if too many HTTP sync packets are
received within a short time, the login window is not displayed. The HTTP packets
that arrive into authenticated port are not taken into account. The higher the number
of HTTP sync packets received at the same time, the more difficult it is to open the
login window. Usually, hundred HTTP sync packets received per second interrupt
WBA service. (CQ149646, CSCui73779)
that arrive into authenticated port are not taken into account. The higher the number
of HTTP sync packets received at the same time, the more difficult it is to open the
login window. Usually, hundred HTTP sync packets received per second interrupt
WBA service. (CQ149646, CSCui73779)
Solution:
Continue to refresh web browser or stop the HTTP sync flood.
