The Microcode Bundle Manager provides an enhancement to the mechanism currently used to load and 
unload microcode bundles on the packet-switching ASIC (PSA) of Engine 2 (E2) line cards on the 
Cisco 12000 series Internet router. The Microcode Bundle Manager has the following benefits:

Provides a simpler way to manage the complexity of the increasing number of software features 
supported on E2 line cards.

Ensures that the correct microcode bundle is consistently and reliably loaded (or unloaded) when 
you enable (or disable) a software feature on an E2 line card. 

MPLS COS Transparency is supported on the 1-port OC-192/STM-64 E4+ DPT line card and on the 
4-port OC-48/STM-16 E4+ DPT line card.
