chassis-mode
Syntax chassis-mode [chassis-mode] [force]
Context config>system
Description This command configures the chassis scaling and feature set and only applies to the 7450 ESS and
7750 SR.
Note that, if you are in chassis-mode d and configure an IOM type as iom2-20g and then downgrade
to chassis-mode a or b (must specify force keyword), a warning appears about the IOM downgrade.
In this case, the IOM provisioned type will downgrade to iom-20g-b. Once this is done, the ASAP
MDA cannot be configured.
The ASAP MDA can only be configured if the iom2-20g IOM type is provisioned and equipped and
the chassis mode is configured as a or b.
If this is the desired behavior for the 7750 SR, for example, chassis-mode d is configured and IPv6 is
running, you can then downgrade to chassis-mode a or b if you want to disable IPv6.
For chassis mode d, the default must be changed from the default mode a which assumes the least
available features. Mode d enables the new feature sets available with newer generations of IOMs.
Chassis mode d supports the P2/Q2/T2-based IOMs products and the extensive queuing/policing/
bandwidth. Mode d assumes that the iom3-xp is installed.
The force command is not available for chassis-mode d.
Default a
Parameters chassis-mode — Specify the one of the following chassis modes:
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 (7750 SR only).
d: This mode corresponds to scaling and feature set associated with iom3-xp.
