Does the 3845 Support Spanning-tree mode MST

I am trying to configure spanning-tree mode MST on a 3845 with an intergrated switch module. However, it will not accept the command. What am I missing?

The hardware configuration of the router is listed below.

STL260LL-AJ19RTR6 uptime is 24 weeks, 1 day, 18 hours, 18 minutes

System returned to ROM by power-on

System image file is "flash:c3845-advipservicesk9-mz.124-5b.bin"

Hi Steve.

It looks like the Etherswitch modules only support PVST
