Cisco Catalyst 6900 Series 4-Port 40 Gigabit Ethernet Fiber Module with DFC4 - Expansion module - 10 GigE, 40 Gigabit LAN - 4 ports - for Catalyst 6503-E, 6504-E, 6506-E, 6506-E IDSM-2, 6509-E, 6509-E

The Cisco Catalyst 6900 series 4-Port 40 Gigabit Ethernet Fiber Module, 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.

Key Features
  • Encapsulation (GRE), IPv6, and VPLS forwarding
  • Increased multicast routes to 256 K
  • Support for 16 K bridge domains, allowing the standard 4 K VLANs to be reused across these bridge domains, effectively increasing the number of VLANs available in the system
  • Increased MAC address table to 128 K
  • IPv4 Internet Group Management Protocol Version 3 snooping in hardware
  • IPv6 Multicast Listener Discovery Version 2 snooping in hardware
  • Protocol Independent Multicast registers in hardware
  • IPV4 and IPv6 in IPv6 tunneling
  • Quality-of-service support for uniform, short pipe, and pipe mode tunnel
  • Terminate the tunnel in the same loopback
  • Layer 2 and Layer 3 Cisco TrustSec and IEEE 802.1ae (MACsec) Layer 2 encryption in hardware
  • Deficit Weighted Round Robin (DWRR)
  • Weighted Random Early Detection (WRED)
  • Ingress and egress mode
  • Approximately 20 Gbps per replication engine
  • Four replication engines per module delivering total throughput of 80 Gbps
