Examples of Layer 2 in a sentence

  • Customer must order and pay for the two access circuits from Verizon to configure Layer 2 Aggregation Geographic Diversity and Carrier Diversity, plus an additional charge for the Diversity Feature itself, as applicable.

  • Layer 2 Control Protocols Processing = initially none (but may be amended by LFC from time to time).

  • With Layer 2 Switch Geographic Diversity, Verizon provides a second Customer circuit connected to a different Verizon Layer 2 switch device (determined by Verizon) in a different building from the primary circuit.

  • Traffic that is generated at Layer 2 on a switched network needs to be managed, or segmented into Virtual Local Area Networks (VLANs), Distribution layer switches provides the inter-VLAN routing functions so that one VLAN can communicate with another on the network.

  • Layer 2 Control Protocols are not transportable over the Service.

  • If connected via a Layer 2 switch instead of a Layer 3 router advice must be sought from the Supplier’s Technical Pre-Sales team.

  • Layer 2 Control Protocols Processing = limited (but may be amended by the LFC from time to time).
