This is the most common workaround for beginners. You do not emulate a 2960 directly. instead, you take a Router (like the Cisco 3725 or 3745) and install a switching module into it.
NM-16ESW module runs switch commands (like switchport mode access). It supports VLANs, STP, and Etherchannel.show vlan brief output formatting or specific QoS commands) might behave slightly differently than a real 2960.For related searches that might help set up specific images, commands, or troubleshoot errors, see suggested search terms below.

After booting, open the console. Run these verification commands:
show version
You should see something like: "IOSv (universalk9_npe-m) software" — if it says "IOSv" (aka IOL), you’re good. A real 2960 would say "C2960 Software." The Experience: You are technically running a router,
show switch
This command only works on real switches. On an IOL L2 image, it may not exist. Instead, test Layer 2 features:
conf t
interface ethernet 0/0
switchport mode access
switchport access vlan 10
spanning-tree vlan 1 priority 4096
do show vlan brief
do show spanning-tree
