Metro Ethernet FAQs

Metro Ethernet Service Level Agreements

What Metro Ethernet Forum (MEF) service types does Cox Business support? Our Metro Ethernet supports the E-line and E-LAN service types as defined by the MEF. The E-line service type can be used to construct point-to-point (P2P) and point-to-multipoint (P2MP) connectivity solutions. The E-LAN service type can be used to construct multipoint-to-multipoint (MP2MP) solutions.

What standards are Cox Business services compliant with? Cox Business Metro Ethernet (CME) is compliant with the current Ethernet standard (IEEE 802.3-2005), and support other related standards, such as IEEE 802.1D-2004 (MAC Bridges), IEEE 802.1Q-2005 (VLAN Bridges), etc. In addition, our products are modeled after and certified to the Ethernet standards as defined by the Metro Ethernet Forum (MEF). The MEF develops technical specifications and implementation agreements to promote interoperability and deployment of carrier-class Ethernet services worldwide.


What service options does Cox Business offer? We offer four service options: Ethernet Private Line (EPL), Ethernet Virtual Private Line (EVPL), Ethernet Private LAN (EP-LAN) and Ethernet Virtual Private LAN (EVP-LAN). EPL is typically used instead of a legacy Private Line service such as TDM service, while EVPL is typically used at a hub or aggregation site where multiple EVS are multiplexed in to a single UNI. EP-LAN and EVP-LAN options are applicable when any-to-any connectivity is required and are typically used in place of legacy transparent LAN services or when contemporary Layer 2 VPNs are required, to name a few.

What is the difference between the "private" service options (EPL and EP-LAN) and the "virtual" service options (EVPL and EVP-LAN)? A “private” service provides a single Ethernet Virtual Connection (EVC) per Ethernet interface. This means all customer ingress traffic is mapped to a single EVC and transported through the Cox Metro Ethernet Network (MEN) to a single destination Ethernet interface (EPL) or to multiple destination Ethernet interfaces (EP-LAN). A “virtual” service provides one or more EVCs per Ethernet interface. This means portions of customer ingress traffic are mapped to multiple EVCs and transported through the Cox MEN to a single destination Ethernet interface (EVPL) or to multiple destination Ethernet interfaces (EVP-LAN). Which portions of customer traffic are mapped to which EVC is determined by the customer “tagging” their traffic with customer VLAN IDs.

What Ethernet interfaces are supported by Cox Business Metro Ethernet? What mode does the Ethernet interface operate in? Do any Ethernet interfaces support auto-negotiation? Metro Ethernet supports a variety of copper and fiber Ethernet interfaces, including 10BASE-T, 100BASE-TX, 1000BASE-T, 1000BASE-LX/SX and 10GBASE-LR/SR/ZR, depending on the customer location.

Is there a limit on the number of EVCs Cox Business will provide per Ethernet interface (UNI)? Yes. Cox Business will provide up to 100 EVCs per UNI as required. This is more than enough to meet even the most demanding customer applications and requirements.

Does Cox Business support the IEEE 802.1Q standard? Yes. Our Metro Ethernet supports the reception of untagged (1518 bytes) and VLAN tagged/priority tagged (1522 bytes) Ethernet Service Frames (ESFs).
