Product Overview

Cisco® Catalyst® 6500 Series Switches offer a variety of Ethernet modules to serve different needs in the campus and data center for enterprise, commercial, and service provider customers. The Cisco Catalyst 6904 4-Port 40 Gigabit Ethernet Fiber Module (Figure 1), fully compliant with the IEEE 802.3ba standard, complements this product portfolio.

The module is designed to meet the increasing demand for aggregation of 10 Gigabit Ethernet on campus and data center, as well as for high-density 10 Gigabit Ethernet and 40 Gigabit Ethernet transport in the core.

Each port can accept a 40 Gigabit Ethernet C Form-Factor Pluggable (CFP) optics module or be converted to four ports of 10 Gigabit Ethernet with a FourX adapter, enabling customers to deploy 10 Gigabit Ethernet to meet current needs and be ready to transition to 40 Gigabit Ethernet without any disruption. The module can also be used in mixed mode, where one side of the card uses two CFP modules for 2 times 40 Gigabit Ethernet ports and the other side uses two FourX adapters for 8 times 10 Gigabit Ethernet ports.

The Cisco Catalyst 6900 Series 4-Port 40 Gigabit Ethernet Fiber Module is compatible only with Cisco Catalyst 6500 Supervisor Engine 2T.

Cisco Catalyst 6900 Series 4-port 40 Gigabit Ethernet Fiber Module can operate in a number of modes. Performance mode enables 80 Gigabit Ethernet performance by using two ports without oversubscription. In Oversubscribed mode, the module uses four ports with 2:1 oversubscription. Details are as follows:

●   40 Gigabit Ethernet Oversubscribed mode (default)
◦     Four 40 Gigabit Ethernet ports using CFP transceivers.
◦     Ports are numbered as interface FortyGigabitEthernetslot#/1-4 (Figure 1).
◦     The interface range command is allowed.
●   10 Gigabit Ethernet Oversubscribed mode
◦     16 10 Gigabit Ethernet ports using FourX adapters.
◦     Each FourX adapter has 4 SFP+ transceivers.
◦     Ports will be numbered as interface TenGigabitEthernetslot#/5-20 (Figure 2).
◦     The interface range command is allowed.
●   Mixed 10/40 Gigabit Ethernet mode
◦     One-half of the module uses two CFP transceivers for 2 x 40 Gigabit Ethernet ports, while the other half uses two FourX adapters for 8 x 10 Gigabit Ethernet ports.
◦     Depending on which side has the 40 Gigabit Ethernet ports, port numbering is as follows:
●   40 Gigabit Ethernet ports on left: Interface FortyGigabitEthernet slot#/1-2 and interface              TenGigabitEthernetslot#/13-20.
●   40 Gigabit Ethernet ports on right: InterfaceTenGigabitEthernetslot#/5-12 and interface              FortyGigabitEthernetslot#/3-4.
●   Performance mode (Figure 3)
◦     Note that Oversubscribed mode is the default setting.
◦     In 40 Gigabit Ethernet Performance mode, ports 1 and 3 will be active.
◦     In 10 Gigabit Ethernet Performance mode, ports 5-8 and 13-16 will be active.
◦     The command-line interface (CLI) is required to change modes. Check release notes for details.
◦     The mode can be changed per port group.

The 4-Port 40 Gigabit Ethernet Fiber Module provides up to 44 x 40 Gigabit Ethernet Fiber ports in a single Cisco Catalyst 6513-E chassis and 88 x 40 Gigabit Ethernet ports in a Cisco Catalyst 6500 Virtual Switching System (VSS) 4T. The module has two 40-Gbps connections (for a total of 80 Gbps) to the 2-Tbps switch fabric of the Cisco Catalyst Supervisor Engine 2T, providing 2:1 oversubscription when all four ports of 40 Gigabit Ethernet or 16 ports of 10 Gigabit Ethernet ports are active.

Cisco Catalyst 6904 modules support two types of CFP optics: CFP-40G-LR4 and CFP-40G-SR4, providing operational distances of up to 10-km over single-mode fiber and 100m over OM3 multimode fiber, respectively. FourX adapters support a variety of Small Form-Factor Pluggable Plus (SFP+) optics, as listed in Table 2.

Each of the 40/10 Gigabit Ethernet ports supports Cisco TrustSec™ technology and IEEE 802.1ae (MACsec) encryption. The 40/10 Gigabit Ethernet ports also support Security Group Access Control Lists (SGACL), also known as Role-Based Access Control Lists (RBACL), and both Layer 2 and Layer 3 Security Group Tagging (SGT) functionality. The module also supports Virtual Switch Link (VSL) on all ports in both
