Release Notes for 200, 300, 500, and ESW2 Series Switches Firmware Version 1.3.0
Release Notes
The following caveats are carried forward from release 1.2.9:
Problem:
Some of the pages in the web-based interface require the Java
Runtime Environment (JRE) to be installed, otherwise they may display incorrectly.
Solution:
Install the latest JRE.
Problem:
Granularity of traffic shaping on the following Uplink ports starts with
2Mbps and not with 64Kbps. When configuring traffic shaping on these ports to
rates lower than 2Mbps, the actual traffic shaping rate will be 2Mbps. (CQ 123397,
CQ 130715, CQ 133170)
rates lower than 2Mbps, the actual traffic shaping rate will be 2Mbps. (CQ 123397,
CQ 130715, CQ 133170)
-
Sx200/Sx300 HW 1.0
-
SF500 ports GE1-GE4
-
SG500 ports GE-49 - GE52
-
SG500X ports XG1 - XG4
Solution:
Use the specified ports when traffic shaping is not required (for
example. uplink or stack ports), or when the required traffic shaping rate is at least
2Mbps
2Mbps
Problem:
When the link on the SG500X ports XG1 - XG4 uplink ports comes up,
the link may go up and down a few times then stabilize on the up state. (CQ 135073)
Solution:
There is no workaround.
Problem:
After frequent changes of the stack topology from ring to chain and vice
versa, one of the stack links might become non-operational (stuck in a state where
even if the stack topology is ring, it will function as a chain). If the remaining
operational stack link goes down, the stack might become non-operational. (CQ
135108)
even if the stack topology is ring, it will function as a chain). If the remaining
operational stack link goes down, the stack might become non-operational. (CQ
135108)
Solution:
Wait for the stack to stabilize before changing its topology.
Problem:
Copper SFP MGBT1 is not supported as stack port due to packet loss
and bad CRC. (CQ 135473)
Solution:
Use Cisco approved SFPs.
Problem:
When a PoE switch is connected to another PoE switch, one of the
switches overcomes the internal power supply of the other PoE switch, so the other
PoE switch cannot provide PoE power to powered devices. If the connection
between these switches is removed, the switch that received power from the other
switch will momentarily lose its power and reboot. (CQ135360, CQ138875).
PoE switch cannot provide PoE power to powered devices. If the connection
between these switches is removed, the switch that received power from the other
switch will momentarily lose its power and reboot. (CQ135360, CQ138875).
Solution:
Disable PoE on the ports connecting the two PoE switches.
