A variety of hardware profiles optimize ASIC resources for counters, port-channels, routes, and Ternary Content-Addressable Memory (TCAM)-allocation.
Note
When you change a hardware profile, the supported scale numbers remain the same with respect to the configuration even if hardware may not be able to fulfill them. This ensures that the same protocol and interface information remain valid with all hardware profile settings.

TCAM profiles TCAM profiles enable you to optimize TCAM resources according to your system requirements.
Counter profiles Counter profiles optimize counters. Common Infrastructure leveraged by applications, to take care of statistics subsystem programming.
FIB compression Border Gateway Protocol (BGP) learns routes from a neighbor and flattens the BGP next-hop route into an IGP next-hop route before downloading those routes to the Routing Information Base (RIB). The RIB then downloads those routes into the Forwarding Information Base (FIB) to program the routes in hardware.
Border profiles for Internet peering Border profiles for Internet peering supports very highly scaled routing tables. This feature is achieved by using hardware optimization by means of an external TCAM (ETCAM) device for Layer 3 routing, as well as by implementing FIB compression.
Hardware profile show commands There are several show commands that display hardware-profile information, as listed in the following table.
