SRW2048 switch - Not accepting subnet mask

Hi all,

I am having an issue with a Linksys SRW2048 managed switch. My issue is that every time I put in my subnet mask (255.255.252.0) & hit save, it reverts to the original subnet mask (255.255.255.0).

Does anyone know why this would be happening? I have tried everything I know & I cannot get it to take the subnet mask. I am at my wits end.

You need the Cisco firmware, verision 1.1.1.8, which resolves a slew of problems with the Linksys firmware. This is completely rewritten firmware from Cisco developers, and includes the IOS command line interface and many, many new features. The GUI is redesigned as well.

Looks like the switch is not able to do classless subnetting, you might want to check if there is an option for that. Also, like packetguy said, it never hurts to get the newest firmware.

This is a known limitation of the old firmware.

Check which ports are open to the outside world. Helps make sure that your firewall rules are working as intended.

Real quick,

The firmware update 1.1.1.8 you are suggesting is for a Cisco SF200-48 48-Port 10/100 Smart Switch, not the Linksys SRW2048. Will this firmware work with the Linksys SRW2048?

Cisco spin off linksys and took the SRW routers back in house, renaming them as the SF- and SG- series. I recommend you go to the Cisco support site and check your serial number with Cisco's equivalent part numbers. That list will also identify the correct firmware file.

Just for reference, according to Cisco the equivalent part for the SRW2048 is the SG 300-52.

This way anyone else that needs to do this kind of firmware upgrade will have the info as well.

Thank you Packetguy for all of the assistance on this. :)
