I would like to know the limit of mac address for this switch 3750X,
I configured the sdm value to this
The current template is "desktop routing" template.
The selected template optimizes the resources in
the switch to support this level of features for
8 routed interfaces and 1024 VLANs.
number of unicast mac addresses: 3K
I would like to know if this will limit the quantity of mac address that can handle the Switch.
Is there a reason why you want to know the number of MAC addresses? For a 3750 I do not think you will ever reach the threshold.
Here is the info taken from the Cisco DataSheet
Cisco Catalyst 3750-X and 3560-X Series Specifications
Table 9 shows Cisco Catalyst 3750-X and 3560-X Series Switches performance specifications.

Performance Numbers for All Switch Models
256 MB (512 MB for 3750X-12S and 3750X-24S)
64 MB (128 MB for 3750X-12S and 3750X-24S)

MAC, routing, security, and QoS scalability numbers depend on the type template used in the switch. Routing template is not supported in the LAN Base feature set. Table 10 shows Cisco Catalyst 3750-X and 3560-X Series Switch scalability numbers.

Hello Luis Ernesto,
Yes, the data displayed in the show sdm prefer command output describe the current limit on the number of MAC addresses. Different SDM templates allow for different limits in diverse features, so according to the intended usage of your switch, you should choose the appropriate SDM template that best fits your needs.
In addtion, you may want to check the output of the show mac address-table count command - at the bottom of the output, the switch indicates the current limit of MAC address count.
