Cisco Cisco SG200-26P 26-port Gigabit PoE Smart Switch

Release Notes for 200, 300, 500, and ESW2 Series Switches Firmware Version 1.2.9

Release Notes

Limitations and Restrictions

The following caveats are acknowledged in release 1.2.9:

Problem:

Some of the pages in the web-based interface require the Jave

Runtime Environment (JRE) to be installed, otherwise they may display incorrectly.

Solution:

Install the latest JRE.

Problem:

When using DHCP option 6, the DNS server priority is based on the

server's IP Address and not on the order of the DNS servers list. (CQ138489)

Solution:

There is no workaround.

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)

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

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)

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.
