Product Overview

Cisco

  • Catalyst 6900 Series
  • 4-Port
  • 40 gigabit
  • Ethernet Fiber Module

Mfg. Part #: WS-X6904-40G-2T

This is only compatible with the Cisco Catalyst 6500 Supervisor Engine 2T. 

This 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
  • 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
  • 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 follow:

  • 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 
  • 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 Oversubscribed mode and Performance mode.

All products have a 90-day money back guarantee, and a 90-day replacement guarantee (based on availability).
