Usage 
Information
If you enter the metric-style wide command, the Dell Networking OS 
generates and accepts only new-style TLVs. The router uses less memory and 
other resources rather than generating both old-style and new-style TLVs.
The new-style TLVs have wider metric fields than old-style TLVs.
