ESM 8668 Metro Ethernet Services Module
The ESM 8668 Metro Ethernet Services Module (Metro ESM 8668) provides
eight 1000Base SFP Gigabit Ethernet ports. The Metro ESM 8668 has the
same architecture as the Metro Ethernet Routing Switch 8600 interface
modules, but also contains an additional network processor in the data path
of each of the eight Ethernet ports.
The heart of the ESM 8668 is the flexible network processor. The network
processor contains four packet processing engines, each running at 400
megahertz (MHz). This architecture provides the flexibility, memory and
processing power to:
•
Implement a highly scalable and feature rich Ethernet VPN solution.
• Enable the highly resilient 50 millisecond (ms) Gigabit Ethernet access
ring solution with the Ethernet Services Unit (ESU) 18x0 product family.
•
Allow future feature enhancements through software upgrades.
See "ESM 8668 Metro Ethernet Services Module" (page 49) for a full
description of the Metro ESM 8668.
8608GBE and 8608GBM modules
Both the 8608GBE and 8608GBM modules ("8608GBE/8608GBM module"
(page 25)) provide eight bays for installing Gigabit interface converters
(GBIC). You can use the ports on the GBICs to make riser connections,
server attachments, or interswitch links.
