ITU-T G.8021.1-2012 PDF

Scope: This Recommendation provides an overview of the functions of Ethernet equipment and gives examples of various Ethernet equipment types. The Recommendation is based on the Ethernet transport network architecture specified in [ITU-T G.8010], the bridge types specified in [IEEE 802.1Q], and equipment functional blocks specified in [ITU-T G.8021]. It is by no means intended to lay down restrictions on the way in which equipment may be built.
