Service Availability
Increased service availability is a critical requirement for service provider networks because most
enterprise customers expect the same level of availability from Carrier Ethernet as they have from
leased-line networks. The Cisco ME 3400E Series supports redundant field-replacable integrated
power supply and fan modules. To quickly activate and troubleshoot services, the Cisco ME 3400E
Series offers traffic loopback capabilities so service providers can remotely verify and monitor
services. Four external alarm inputs allow service providers to respond quickly to changes in the
switch’s environmental condtions before failure occurs.
To further increase service availability on a networkwide level, Cisco ME 3400E offers Flexlink for
sub-50-ms failover, Resilient Ethernet Protocol (REP), Link-State Tracking, IEEE 802.1w Rapid
Spanning Tree Protocol (RSTP), per-VLAN Rapid Spanning Tree Plus (PVRST+), and the Cisco
Hot Standby Router Protocol (HSRP). These capabilities help to create redundant, failsafe
topologies. Strong, built-in security in three tiers – network, switch, and subscriber – helps prevent
the device and the network from succumbing to malicious attacks, thereby enhancing network
uptime.
Resilient Ethernet Protocol (REP) is a Cisco proprietary protocol that provides an alternative to
Spanning Tree Protocol to control network loops, handle link failures, and improve convergence
time. REP enables fast and predicable reconvergence for Layer 2 networks. In addition, REP
supports VLAN load balancing to enable efficient utilization of redundant links.
Service Flexibility
As more enterprises adopt Carrier Ethernet technology, the demand on service providers’ abilities
to offer new services increases. The Cisco ME 3400E Series offers 1:1 VLAN translation which
allows end customers the flexibility of choosing their own internal VLANs without affecting the core
service provider’s network. In some instances, service providers need to provide multiple EPL
(Ethernet Private Line) services on a single UNI (User Network Interface). With the Selective QinQ
feature, the Cisco ME 3400E Series helps service providers to offer multiple Ethernet Virtual
Private Line (EVPL) services on a single UNI. To support the need for next-generation enterprise
services, customers are lookings for more QoS functionalities to support differenty types of
applicatoins. To meet the need for ever stringent QoS requirements from customers, the Cisco ME
3400E Series offers 2-rate 3-color policer with byte-level statistics at ingress ports and inner-to-
outer CoS mapping to help service providers offer differentiated services with high profit margins.
Service Manageability
With today’s sophiscated networks, service providers are always looking for ways to reduce
operational expenses (OpEx) and increase profit margins. The Cisco ME 3400E Series provides
the following tools to help service providers simplify the management of their Ethernet services.
Traffic loopback capabilities to help service providers activate and troubleshoot new and existing
services without expensive truck rolls. The “dying gasp” alert for loss of power and four external
alarm inputs to detect changes in remote sites further help service providers to manage the health
of their equipment. And an Ethernet management port provides dedicated access for service
providers to monitor and provision the switch.
In addtion, the Cisco ME 3400E Series includes Generic Online Diagnostics (GOLD) and Onboard
Failure Logging (OBFL) to help service providers avoid potential problems before they occur and
troubleshoot and diagnose issues once they happened. With features such as Embedded Event
Manager (EEM), Ethernet Operations, Administration, and Management (OAM), and Time-Domain
