SFP Module Ports

The Cisco ME switch supports Gigabit Ethernet and 100 megabit Ethernet, field-replaceable

SFP transceiver modules to establish fiber-optic and copper connections to other network devices. The SFP modules that use fiber-optic connections need fiber-optic cables with LC connectors. The

SFP modules that use copper connections need Category 5 or higher cables with RJ-45 connectors.

The Cisco ME switch uses Gigabit Ethernet SFP modules to establish fiber-optic and 1000BASE-T connections. These transceiver modules are field-replaceable, providing the interfaces when inserted in an SFP module slot. You can use the SFP modules for Gigabit connections to other switches.

The 10/100 Fast Ethernet ports and the dual-purpose ports on Cisco ME 3400-12CS and

Cisco ME 3400-2CS switches are configured as UNIs. The SFP module uplink ports are configured as NNIs. If the switch is running the metro base or metro access image, you can configure only four ports on the switch as NNIs at one time, but you can configure all ports on the switch as UNIs. Starting with Cisco IOS Release 12.2(25)SEG, if the switch is running the metro IP access image, you can configure an unlimited number of NNIs.

Note The Cisco ME-3400-24FS switch downlink ports support only the 100BASE-BX, 100BASE-FX, and 100BASE-LX SFP modules.

For more information on configuring interfaces, see the software configuration guide. For more information about cabling specifications for SFP modules, see the “SFP Module Cable Specifications” section on page A-4.

SFP Modules

The Cisco ME switch supports these Cisco SFP modules:

100BASE-BX

100BASE-FX

100BASE-LX

1000BASE-BX

1000BASE-LX/LH

1000BASE-SX

1000BASE-T

1000BASE-ZX

CWDM

DWDM

When installed in Cisco ME switches, 1000BASE-T SFP modules can operate at 10, 100, or 1000 Mb/s in full-duplex mode or at 10 or 100 Mb/s in half-duplex mode. For more information about these SFP modules, see your SFP module documentation.

You can use any combination of SFP modules that your switch supports. The only restrictions are that each port must match the wavelength specifications on the other end of the cable and that the cable must not exceed the stipulated cable length for reliable communications listed in the “SFP Module Cable Specifications” section on page A-4.

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.
