Since its EoL. you many not get as support, do you have CCO account then you can download.

Hello @magyshanks2020 

>> c3500xl-c3h2s-mz-120.5.2-XU .bin

this should be the latest. However, the device was considered old more then 10/12 years ago so I am not sure that it supports DHCP snooping.

Hope to help

Not Supporting DHCP snooping i got this version already and whenever i type DHCP Snooping command... i get invalid marker

Hello @magyshanks2020 ,

as I have tried to explain the C3500XL is very old. They had a way to create a stack using proprietary 1Gbps optics.

In order to support DHCP snooping you would need a true multilayer switch with powerful ASIC,  TCAM and CPU.

The C3500XL should be just a plain L2 switch not powerful enough to support a feature like DHCP snooping.

Hope to help

WC17 is the latest and the last firmware version.  

"XU" is the Interim Version which is what the factory loads.  XU is not meant to used in production.  

2900/3500 do not support DHCP snooping.
