The WS-X6408A-GBIC is an 8-port Gigabit Ethernet line card designed for the Cisco Catalyst 6500 and 6000 series modular switches. It uses GBIC (Gigabit Interface Converter) transceivers to provide flexible fiber or copper connectivity. This enhanced version of the WS-X6408 includes improved Quality of Service (QoS) features, making it suitable for enterprise core and aggregation networks requiring scalable gigabit connectivity.
