From the datasheet-

Configurable up to 12,000 MAC addresses (Cisco Catalyst 3750G-24TS, 3750G-24WS, 3750G-24T, 3750G-12S, 3750-24TS, 3750-24FS, 3750-24PS, 3750-48TS, 3750-48PS, 3750G-24TS-1U, 3750G-24PS, 3750G-48TS, 3750G-48PS, and 3750G-16TD)

Hope that helps.

To add to Collin's post, also depends on the SDM template you use -


MAC Addresses

• Desktop Default SDM template: 6K

• Desktop Routing SDM template: 3K Desktop VLAN SDM template: 12K

• Aggregator Default SDM template: 6K Aggregator Routing SDM template: 6K

• Aggregator VLAN SDM template: 12K

• WS-C3750G-12S Aggregator VLAN SDM template: 20K

Think I have found a way to get this figure. Please confirm that this is the correct way.


At the end of a "show mac address-table" output is:

Total Mac Addresses for this criterion: 2074


The end of a "show mac address-table" output is:

Total Mac Address Space Available: 3456


Adding the two figures above yields 5530


Would this be one way to find out the maximum number of mac addresses a 3750 switch can support?

You're probably using the default SDM template which is 6K (per Jon). show sdm prefer will show you what template you're using.


Hope that helps.
