Cisco Catalyst 9500 Series 48-port

25G switch C9500-48Y4C-E


  • The Cisco® Catalyst® 9500 Series switches are the next generation of enterprise-class core and aggregation layer switches, supporting full programmability and serviceability. Based on an x86CPU, the Cisco Catalyst 9500 Series is Cisco’s lead purpose-built fixed core and aggregationenterprise switching platform, built for security, IoT, and cloud. The switches come with a 4-corex86, 2.4-GHz CPU, 16-GB DDR4 memory, and 16-GB internal storage.


    The Cisco Catalyst 9500 Series is the industry’s first purpose-built 25, 40 and 100 Gigabit Ethernetline of switches targeted for the enterprise campus. These switches deliver unmatched table scale(MAC/route/ACL) and buffering for enterprise applications. The Cisco Catalyst 9500 Series includesnonblocking 40 and 100 Gigabit Ethernet Quad Small Form-Factor Pluggable (QSFP+, QSFP28)

    and 1, 10 and 25 Gigabit Ethernet Small Form-Factor Pluggable Plus (SFP/SFP+/SFP28) switcheswith granular port densities that fit diverse campus needs. The switches support advanced routingand infrastructure services (such as Multiprotocol Label Switching [MPLS] Layer 2 and Layer 3VPNs, Multicast VPN [MVPN], and Network Address Translation [NAT]); Cisco Software-Defined

    Access capabilities (such as a host tracking database, cross-domain connectivity, and VPN Routingand Forwarding [VRF]-aware Locator/ID Separation Protocol [LISP]); and network system virtualizationwith Cisco StackWise® virtual technology that are critical for their placement in the campus core.

    The Cisco Catalyst 9500 Series also supports foundational high-availability capabilities such aspatching, Graceful Insertion and Removal (GIR), Cisco Nonstop Forwarding with Stateful Switchover (NSF/SSO), redundant platinum-rated power supplies, and fans.
