Configuring the Chassis Mode
Depending on the chassis type and IOM type, the following modes can be configured:
a: This mode corresponds to scaling and feature set associated with iom-20g.
b: This mode corresponds to scaling and feature set associated with iom-20g-b.
c: This mode corresponds to scaling and feature set associated with iom2-20g.
d: This mode corresponds to scaling and feature set associated with iom3-xp.
If the chassis mode is not explicitly provisioned in the configuration file, the chassis will come up
in chassis mode a by default. The behavior for the IOMs is described in the following table:
To support a particular chassis-mode, all provisioned IOMs must meet the corresponding IOM
level.
The chassis Mode corresponds to scaling and feature sets associated with a given card. The base
mode is chassis mode A which supports all IOM card types.
NOTE: Chassis modes are not available on the 7750 SRc12 router.
