PRODUCT OVERVIEW & MARKET POSITIONING
The modern enterprise campus network demands a core switching platform that simultaneously delivers carrier-grade reliability, wire-speed performance, and future-ready scalability. The [MODEL_CORE_SWITCH] series has been architected to serve as the unified fabric for high-density campus environments, consolidating Gigabit-to-100G Ethernet access layers, security services, and network virtualization overlays without compromise.
ARCHITECTURE & CHASSIS DESIGN
Based on a non-blocking Clos switching fabric, the [MODEL_CORE_SWITCH] deploys a distributed forwarding architecture with hardware-based VXLAN routing and inline encryption offload. The modular chassis supports hot-swappable supervisor engines, line cards, power supplies, and fan trays—all accessible from the front or rear (reversible airflow option). Key design pillars include:
– 4.8 Tbps to 25.6 Tbps switching capacity (depending on line card population)
– Sub-microsecond port-to-port latency for all frame sizes
– Hardware-assisted In-Service Software Upgrade (ISSU) with zero packet loss
– Support for 400 GbE downlink/uplink optical interfaces
HARDWARE FEATURES & PERFORMANCE CAPABILITIES
The switching engine integrates a programmable pipeline ASIC supporting P4 language extensions. Feature highlights:
– MAC address table: 512K entries
– IPv4/IPv6 route table (FIB): 1M routes
– ACL rules: 32K ingress + 16K egress
– Jumbo frame support up to 12K bytes
– 1+1 route processor redundancy with sub-100 ms failover
– N+1 fabric module redundancy for fully distributed forwarding

DEPLOYMENT TOPOLOGY EXAMPLE
Typical deployment: Two [MODEL_CORE_SWITCH] units in a Virtual Port Channel (vPC) / StackWise Virtual configuration, each connecting to distribution switches (10G/25G uplinks) and downstream access switches (1G/10G). Core links operate at 40G/100G to aggregation routers and firewall clusters. L2/L3 gateway services, VXLAN EVPN multi-tenancy, and MACsec on all inter-switch links complete the architecture.
