SG 300-28 28-Port Gigabit Managed Switch -Lan connectivity issues

Hello,

Our office lan running on 2 * SG 300-28 28-Port Gigabit Managed Switch.

PID VID:SRW2024-K9 V01

Firmware Version (Active Image):1.0.0.27

The users are seeing there connection to fileservers(mapped network drives) slowing down over the period.

We have to re-boot the offending switch to get the normal traffic back.

I have raised a ticket with cisco small business people and they said to upgrade the firmware to latest version.

But I am wondering why I need to upgrade this switch as the other switch which also brought at the same time with the same spec have no such issues.

Even if I decided to upgrade the firmware, they have recommended that I need to reset the switch to factory settings and try to put the previous configuration manually which is a worry for me.

I have logged on to the web console and I have found out, I can use TFTP or HTTP to backup the config,how do I use those services and what parameters i need to pass those to work, does using that functionality can rollback the switch to previous running configuration?

PS: Both the switch have connected together using a FC trunk with link aggregation eanbled.So how do I get all those settings back if I upgrade/rollback?

I just have to come up with some solution as it is affecting the business, so any help would be much appreciated.

Please see the attachment and let me know if any other info needed?

Thanks in advance,

Regards

Suji

Hi Smith, the 1.0.0.27 is the first production release software for this switch.  If you'd like, upgrade to the 1.1.2.0 and give that a try. It should not need a factory reset after the upgrade. Anything later really should need a reset because it changes howeverything works inside.

To make a a backup, log in to the switch HTTP, go to Adminstration ->File Management -> Download/Backup config

Hi Tom,

Thanks for the reply.

If I choose HTTP I get 3 options.

first its save action >download or backup.

second Source File name :Browse ?(How do I browse to the source file,I don't think it's possible if I am using the web interface from my local pc)

Third option for Destination file type > Running config or Startup config or backup config

SG 300-28 28-Port Gigabit Managed Switch -Lan connectivity issue

Hi,

Please see the difference between the connected switches configuration.

Maybe the vlan 10 and 30 has been created wrongly.

Please see the config for both the switches and give me some advice/suggestions.

I really appreciate that.
