Cisco ME 3400E Series Ethernet Access Switches are next-generation Layer 2 and Layer 3 customer-located devices for service providers. Their design is based on the widely deployed Cisco ME 3400 Series Ethernet Access Switches. The Cisco ME 3400E Series helps service providers deliver four key attributes that are essential to next-generation Carrier Ethernet service: availability, flexibility, manageability, and security.
Product Overview
With service-provider-friendly features, the Cisco ME 3400E Series is the second-generation Cisco access switch optimized for Ethernet-to-the-Business (ETTB) VPN services. It provides both high availability and service flexibility for Carrier Ethernet business access deployments. The Cisco ME 3400E Series comes by default with advanced Layer 2 VPN service features and the option to upgrade to Layer 3 VPN services, giving service providers an out-of-the-box business VPN solution that can be scaled to meet future needs.
The Cisco ME 3400E Series (Figure 1) includes the following configurations:
● Cisco ME 3400EG-12CS chassis (part number ME-3400EG-12CS-M) with 12 dual-purpose (10/100/1000 and Small Form-Factor Pluggable [SFP]) ports, four SFP uplinks, and two slots for field-replaceable modular power supply and fan unit
● Cisco ME 3400EG-2CS chassis (part number ME-3400EG-2CS-A) with two dual-purpose (10/100/1000 and SFP) ports, two SFP uplinks, and an integrated AC power supply
● Cisco ME 3400E-24TS chassis (part number ME-3400E-24TS-M) with 24 Ethernet 10/100 ports, two dual-purpose (10/100/1000 and SFP) uplinks, and two slots for field-replaceable modular power supply and fan unit
Default Behaviors | Benefits |
UNI/ENI default: Down | Ports must be activated by the service provider before customers can receive service. |
UNI/ENI default: No local switching | Circuit-like behavior protects customers from each other. |
UNI/ENI default: Configurable control plane security enabled | Control-plane packets ingressing from the UNI/ENI are dropped in hardware to protect against denial-of-service (DoS) attacks by default. Unlike UNI ports, ENI ports give service providers the flexibility to selectively discard or peer with customer’s control plane traffic on a per-port, per-protocol basis for the following Layer 2 protocols: Cisco Discovery Protocol, Link Layer Discovery Protocol (LLDP), Link Aggregation Control Protocol (LACP), Port Aggregation Protocol (PAgP), and Spanning Tree Protocol. |
NNI default: Up | Enables automated configuration of the switch through a Dynamic Host Configuration Protocol (DHCP) or BOOTP server. |
