Hardware MDB profile is used to modify router resources for the specific needs during the router boot up time. You can configure the hardware MDB profile or you can view the default profile. The hardware MDB profiles are applicable for base and scale line cards of fixed and modular Cisco NCS 5700 Series Routers.
Hardware MDB profile feature was introduced in Cisco IOS XR software Release 7.4.1 with l3max and l3max-se configuration profile options. Starting from Cisco IOS XR software Release 7.6.1, it supports l3max , l3max-se , l2max , and l2max-se profiles, and provides high scale layer 2 and layer 3 services. Router with base line cards supports l2max and l3max profiles, and routers with scale line cards support l2max-se and l3max-se profiles.
All features that are supported on l3max or l3max-se hardware profile are also supported on l2max or l2max-se hardware profile and the features that are supported on l2max or l2max-se hardware profile are also supported on l3max or l3max-se hardware profile respectively.
Use the hw-module profile mdb command in the Global Configuration mode to configure the hardware MDB profile options.
Modular routers boots up in the Cisco NCS 5700 Series compatibility mode by default. You can configure the router to boot up in native mode and with the desired MDB profile.
Following tables provides the base and scale profiles of MDB for Cisco NCS 5700 Series Routers and Line Cards.
