Version Description
8.3.12.0 Introduced on the S4810.
Usage
Information
If you enter the metric-style wide command, the Dell EMC 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.
When wide transition is configured, narrow metric is sent for the narrow metric TLV and the actual wide
metric is sent in wide metric TLV. The receiver can choose to use the metric that is requires.
