If the chassis mode is not explicitly provisioned in the configuration file, the chassis will come up in Mode A by default. In Mode A: circle6 iom-20g-b comes online if provisioned as iom-20g or iom-20g-b circle6 iom2-20g comes online if provisioned as iom-20g, iom-20g-b or iom2-20g circle6 iom-10g comes online if provisioned as iom-10g circle6 iom3 comes online if provisioned as iom3 Note All IOMs must be IOM3 in order to configure chassis mode D.

For example the 2 port, 10 Gigabit Ethernet MDA Type is non-oversubscribed on the IOM3 and oversubscribed on the IOM2.
