CE-MR-6 Ethernet Card

This section describes the operation of the CE-MR-6 card supported on the ONS 15310-MA. The CE-MR-6 card installed in ONS 15310-MA is restricted to SONET operations.

Provisioning is done through Cisco Transport Controller (CTC) or Transaction Language One (TL1). Configurations through Cisco IOS terminal are not supported on the CE-MR-6 card.

For Ethernet card specifications, refer to the Cisco ONS 15310 Reference Manual. For step-by-step Ethernet card circuit configuration procedures, refer to the Cisco ONS 15310 Procedure Guide. Refer to the Cisco ONS SONET TL1 Command Guide for TL1 provisioning commands.

CE-MR-6 Overview

CE-MR-6 card is a 5 Gbps data module for use in the Cisco ONS 15310-MA. It provides support for L1 packet mapping functions (Ethernet to SONET). The 10/100/1000 Mbps Ethernet-encapsulated traffic is mapped to SONET circuits. Each circuit has three main attributes:

•Low order or high order

•Contiguous concatenation (CCAT) or virtual concatenation (VCAT)

•Generic framing procedure (GFP), LEX, high-level data link control (HDLC), or PPP (point-to-point protocol) based framing.

The CE-MR-6 cards support LCAS that allows hitless dynamic adjustment of SONET link bandwidth.

The CE-MR-6 is a Layer 1 (Ethernet Private Line) and Layer 1+ (Virtual Private Wire Services) mapper card with six IEEE 802 compliant 10/100/1000 Mbps Ethernet ports that provide 1:1 mapping of Ethernet ports to circuits. It maps each port to a unique SONET circuit in a point-to-point configuration. Figure 17-6illustrates a sample CE-MR-6 application. In this example, data traffic from the Fast Ethernet port of a switch travels across the point-to-point circuit to the Fast Ethernet port of another switch.

The CE-MR-6 card allows you to provision and manage an Ethernet private line service like a traditional SONET line. CE-MR-6 card applications include providing carrier-grade Ethernet private line services and high-availability transport.

The CE-MR-6 card carries any Layer 3 protocol that can be encapsulated and transported over Ethernet, such as IP or IPX. The Ethernet frame from the data network is transmitted on the Ethernet cable into the 10/100/1000 Mbps Ethernet ports on a CE-MR-6 card. The CE-MR-6 card transparently maps Ethernet frames into the SONET payload using packet-over-SONET/SDH (POS) encapsulation. The POS circuit, with its encapsulated Ethernet inside, is then multiplexed onto an optical card like any other
