End of life for WS-C3750X-48-S

[alameerb]

Hi Team, 

I want to know the end of life and support for WS-C3750X-48-S cisco switch.

Thank you!

[Jens Albrecht]

Hi @alameerb,

these switches reached end of support already back in October 2021 and are considered obsolete since then, meaning you do not get any software or hardware support from Cisco.

Even their direct successors, the 3850 series will reach this state later this year and you need to move to the Cat9k series switches to run a supported platform.

HTH!

Above will confirm what @Jens Albrecht already described about the 3750-X series.

In above, you'll see only the hardware was still supported through 10/2021.  Other support was curtailed even earlier.

BTW, as Jens notes, (Cisco) would consider a 3750-X "obsolete", does that mean your network is at high risk?  Not necessarily, much would depend on various factors, which should be carefully assessed to determine how and when to deal with the device being EoL.

Hi Joseph, 

The link you provided doesn't shows the Last Date of Support OR the Last date for maintenance for C3850 switch, could you please send the link shows this information?

Thanks!

Probably not yet announced.

However, usually Cisco uses a set of fixed time periods for the various EoL stages.  So, if you look at the timespans for the 3750-X, likely similar will be used for 3850 series.

BTW, the references I provided are the two most recent Cisco has listed.

The EOL notice for the 3850 series was published back on October 31, 2019.

@alameerb The document you are looking for is this one:

There are two models that replaces the 3750X-24S: 

1.  9300-24S (24-ports x 1 Gbps optic only); or

2.  9300X-24Y (24 ports x 25G/10G/1G SFP28)

IMPORTANT:  9300X switches can only be stacked with 9300X models.  9300X will not stack with 9300 or 9300L.
