To enable mixed mode

Before you begin

Enabling mixed mode only applies to 7750 SR devices.

Mixed-mode is the default behavior for all 7450 ESS chassis, which allows the 7450 ESS chassis to support all 7750 SR functionality.

7750 SR-7 and 7750 SR-12 devices also support mixed mode, which allows you to enable IPv6 in chassis mode A or B, without having to upgrade an entire chassis. Slots with network ports, and ports that require IPv6 support, can then be selectively upgraded for IOM3-XPs (SROS Release 20.10 and earlier) or IMMs.

Note: You cannot enable mixed mode on a 7750 SR-7 or 7750 SR-12 that has a provisioned ISA TMS MDA.
