The Catalyst 9500 Series is the industrys first purpose-built 25, 40 and 100 Gigabit Ethernet
line of switches targeted for the enterprise campus. These switches deliver unmatched table scale
(MAC/route/ACL) and buffering for enterprise applications. The Catalyst 9500 Series includes
nonblocking 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) switche
with granular port densities that fit diverse campus needs. The switches support advanced routing
and infrastructure services (such as Multiprotocol Label Switching [MPLS] Layer 2 and Layer 3
VPNs, Multicast VPN [MVPN], and Network Address Translation [NAT]); Software-Defined
Access capabilities (such as a host tracking database, cross-domain connectivity, and VPN Routing
and Forwarding [VRF]-aware Locator/ID Separation Protocol [LISP]); and network system virtualization
with StackWise® virtual technology that are critical for their placement in the campus core.
The Catalyst 9500 Series also supports foundational high-availability capabilities such as
patching, Graceful Insertion and Removal (GIR), Nonstop Forwarding with Stateful Switchover
(NSF/SSO), redundant platinum-rated power supplies, and fans.
