7450 ESS

Overview

The Nokia 7450 Ethernet Service Switch supports service-aware Ethernet aggregation across IP/MPLS-based networks, providing VPLS, VLL and advanced IP services. The 7450 ESS supports a wide range of interfaces.

A Network Domain feature allows users to determine which network ports are eligible to transport traffic of individual SDPs. This information is used for the SAP-ingress queue allocation algorithm applied to VPLS SAPs. See Chapter 27, NE routing and forwarding for more information.

The NFM-P provides network management functions for the 7450 ESS.

The 7450 ESS OAM toolkit includes ITU-TY.1731 with Synthetic Loss Measurement (SLM), IEEE 802.1ag, IEEE 802.3ah, Ethernet local management interface (E-LMI), VPLS OAM and service mirroring. This toolkit is also integrated into the NFM-P.

Mixed-mode

Mixed-mode is the default behavior for all 7450 ESS chassis. This mode of operation allows a 7450 ESS chassis to support all 7750 SR functionality. All supported IOMs and IMMs for the 7450 ESS chassis are 7750 SR-capable, so the 7450 ESS chassis will always operate in this mode.

Automatic provisioning for CPM5 SFMs

The NFM-P automatically provisions and configures the integrated SFMs of CPM5s that feature built-in modules. The automated provisioning occurs during node discovery.

7750 SR-B chassis support

The 7750 SR-12-B and 7750 SR-7-B chassis types are supported on both 7450 ESS and 7750 SR, Release 15.0 R5 or later. The chassis employ the FP4 chipset, which supports multi-terabit-per-second routing.

All existing features, IOM/IMMs, SFMs, CPMs, PEMs, and fan trays are supported in the B chassis.
