tmnxChassisMixedModeIomAdminMode

Module: TIMETRA-CHASSIS-MIB

OID (symbolic): TIMETRA-CHASSIS-MIB::tmnxChassisMixedModeIomAdminMode

OID (numeric): 1.3.6.1.4.1.6527.3.1.2.2.1.3.1.25

Node type: OBJECT-TYPE

Type: TmnxEnabledDisabled

Access: read-create

Description: The value of tmnxChassisMixedModeIomAdminMode specifies if the chassis should allow functionally to run with a mixture of forwarding hardware.

When 'enabled(1)' on a 7450 chassis it allows SR functionality to be configured. SR functionality is a superset of ESS functionality. Once tmnxChassisMixedModeIomAdminMode is enabled, additional IOMs can be converted to SR functionality by setting the tmnxCardCapability field of the corresponding tmnxCardEntry.

When 'enabled(1)' on a 7750 chassis it allows allows IPv6 functionality without requiring chassis mode C or better.

tmnxChassisMixedModeIomAdminMode is only applicable when tmnxChassisType indicates the chassis type is 7450 ESS-6, 7450 ESS-6v, 7450 ESS-7, 7450 ESS-12, 7750 SR-7 or 7750 SR-12.

What is tmnxChassisMixedModeIomAdminMode?

This read-create flag enables mixed-mode operation, allowing a 7450 ESS chassis to run SR-superset functionality (or a 7750 chassis to run IPv6 without a higher chassis mode) on specific IOM slots. It's only applicable on 7450 ESS-6/6v/7/12 or 7750 SR-7/SR-12 chassis, and setting it enabled(1) is a prerequisite before individual IOM slots can be flipped to SR capability via tmnxCardCapability.
