I have 2 WS-C750X-48P Switches when I try to change the SDM Template

[lacroixjamie201938782]

This error message pops up.

WS-C3750X-II#show sdm prefer dual-ipv4-and-ipv6
"unknown" template:
WS-C3750X-II#
Aug 8 18:41:10.683: strider_system_get_template:template_id INVALID : 7

Any help will as always be greatly appreciated.

If the stack master is a desktop switch and a Catalyst 3750-12S running the aggregator template is added
as a stack member, the stack operates with the desktop template selected on the stack master. This could
result in configuration losses on the Catalyst 3750-12S if the number of TCAM entries on it exceeds
desktop template sizes.
If the stack master is a Catalyst 3750-12S switch using an aggregator template and a new stack member
is not a Catalyst 3750-12S, the stack member is not able to support the template that is running on the
stack master. The switch attempting to join the stack goes into SDM mismatch mode, the stack master
does not attempt to change the SDM template, and the switch cannot be a functioning member of the
stack.

I most definitely accept what you're saying, I guess then my next question
would be. Which is the appropriate SDM for both IPV4 and IPV6?

As far as I can tell, that template for Dual IPV4 & IPV6 was file until I
mucked with something and did a full system erase.

What particular model 3750?

What IOS image running on it?

[lacroixjamie201938782]

I have 2 WS-C3750X-48P-L, the IOS version would be c3750e-universalk9-mz.152-4.E10/c3750e-universalk9-mz.152-4.E10.bin

-L's?

Long time since I've worked with 3750Xs, but are -L's a LAN BASE or some such version?  If so, I'm wondering if some SDM templates are not "allowed" to be used.
