The 16-Port Gigabit Ethernet switching module (WS-X6816-GBIC) provides 16 switched, full-duplex Gigabit Ethernet ports that you can configure with any combination of 1000BASE-SX, LX/LH, and ZX GBICs, Copper GBICs, or CWDM GBICs.

Additional Information

Backplane Connection: Switch fabric (dual channel)
Forwarding: Distributed forwarding with integrated DFC
Number of Transmit Queues/Port: 3
Number of Receive Queues/Port: 2
The WS-X6816-GBIC is a fabric-dependent module that has enhanced QoS features
The QoS port architecture (Rx/Tx) for this module is 1p1q4t/1p2q2t
Optics: Support hot-pluggable GBICs over single-mode fiber
Forwarding performance: Forward packets up to 24 Mpps per slot when interface modules have dual-fabric connections
Fabric connection: Connect using dual 8-Gbps full-duplex serial channel connections to fabric on a Supervisor Engine 720 or a SFM
