Front Panel Description

10/100 Ports (Only the Cisco ME-3400-24TS Switches)

You can set the 10/100 ports on the Cisco ME 3400-24TS switches to operate in any combination of half duplex, full duplex, or 10 or 100 Mb/s. You can set the ports for speed and duplex autonegotiation, in compliance with IEEE 802.3ab. The default setting is autonegotiate.

When set for autonegotiation, the port senses the speed and duplex settings of the attached device and advertises its own capabilities. If the connected device also supports autonegotiation, the switch port negotiates the best connection (the fastest line speed that both devices support and full-duplex transmission if the attached device supports it) and configures itself accordingly. In all cases, the attached device must be within 328 feet (100 meters).

User-network interfaces (UNIs) and network node interfaces (NNIs) are supported on the Cisco ME switches. UNIs are typically connected to a host, such as a PC or a Cisco IP phone. NNIs are typically connected to a router or to another switch. By default, the 10/100 ports on the Cisco ME switch are configured as UNIs.

A port can be reconfigured from UNI to NNI and the reverse. When a port is reconfigured as another interface type, it inherits all the characteristics of that interface type. All ports on the Cisco ME switch are either UNI or NNI at any time.

For information on configuring interfaces, see the software configuration guide.

Dual-Purpose Ports (Only the Cisco ME 3400G-12CS and Cisco ME 3400G-2CS Switches)

You can configure the dual-purpose ports on the Cisco ME 3400G-12CS switches and the

Cisco ME 3400G-2CS switches as either 10/100/1000 ports or as SFP module ports.

You can set the 10/100/1000 ports to autonegotiate. You can also configure them as fixed 10, 100, or 1000 Mb/s (Gigabit) Ethernet ports.

The switch dynamically selects the media type for each dual port (10/100/1000BASE-T or SFP). When a link is achieved on one media type, the switch disables the other media type until the active link goes down. If links are active on both media, the SFP module port has priority. You cannot configure this priority.

UNIs and NNIs are supported on the dual-purpose ports. UNIs are typically connected to a host, such as a PC or a Cisco IP phone. NNIs are typically connected to a router or to another switch. By default, the dual-purpose ports are UNIs. A port can be reconfigured from UNI to NNI and the reverse. When a port is reconfigured as another interface type, it inherits all the characteristics of that interface type. All ports on the Cisco ME switch are either UNI or NNI at any time.

You can configure the speed and duplex settings consistent with the selected media type.

For information on configuring interfaces, see the software configuration guide.

ME 3400 specifications

Cisco Systems ME 3400 Series is a robust family of Ethernet access switches designed specifically for service provider environments. These switches are engineered to deliver excellent performance, reliability, and flexibility, making them ideal for deploying Layer 2 and Layer 3 services to residential and business customers.

One of the prominent features of the ME 3400 series is its support for advanced Ethernet technologies. It provides extensive support for both traditional and modern Ethernet services, including Carrier Ethernet. With features such as Ethernet Operations, Administration, and Maintenance (EOAM), the ME 3400 aids in managing network performance and troubleshooting issues effectively. This capability ensures that service providers can deliver high-quality services and maintain optimal network health.

The ME 3400 series includes various models that support a range of port configurations, enabling scalability and adaptability to different network needs. This includes support for both Fast Ethernet and Gigabit Ethernet interfaces. The switches can accommodate multiple speed configurations, making them versatile for diverse deployment scenarios, from small businesses to large enterprise networks.

Another key characteristic of the ME 3400 is its integrated support for resilient Ethernet technologies, such as EtherChannel, Spanning Tree Protocol (STP), and Rapid Spanning Tree Protocol (RSTP). These technologies enhance redundancy and improve network reliability, crucial for service providers who require minimal downtime and high service availability.

Security is a top priority for service providers, and the ME 3400 series addresses this with extensive security features. It supports VLANs for traffic segmentation, access control lists (ACLs) for traffic filtering, and DHCP snooping to prevent unauthorized access to the network. These security measures ensure that both consumer and enterprise traffic remains isolated and secure.

Additionally, the ME 3400 series supports IPv4 and IPv6 routing, offering flexibility for service providers to cater to a broad customer base. The ability to manage both protocols ensures that networks can evolve seamlessly as internet traffic transitions to IPv6.

With energy efficiency increasingly becoming a concern, Cisco has integrated power-saving features into the ME 3400 series. These switches support Energy Efficient Ethernet (EEE) technology, which reduces power consumption during periods of low traffic, helping service providers to reduce operational costs.

In summary, the Cisco ME 3400 series is a versatile platform rich in features that streamline service delivery while ensuring high performance, security, and energy efficiency. It is an ideal choice for service providers looking to enhance their Ethernet services and meet evolving customer demands.
