Cisco Nexus 3132Q DATA CENTER Switch

(N3K-C3132Q-40GE)

Categories: , , ,

The Cisco Nexus 3132Q is a 40-Gbps Quad Small Form-Factor Pluggable (QSFP) switch with 32 Enhanced QSFP (QSFP+) ports. It also has 4 SFP+ ports that are internally multiplexed with the first QSFP port. Each QSFP+ port can operate in native 40-Gbps or 4 x 10-Gbps mode, up to a maximum of 104 x 10-Gbps ports.
