About the Cisco Catalyst 6500/6800 C6840-X-1100W Cisco Catalyst switch
The Cisco Catalyst 6840-X-1100W delivers enterprise-grade switching with an integrated 1100W AC power supply designed to support demanding core and distribution layer deployments. This fixed configuration standalone switch combines managed Layer 2 and Layer 3 switching capabilities with robust routing protocols including Static routing, OSPF, EIGRP, BGP, and IS-IS (IOS-dependent), making it ideal for network engineers architecting scalable, resilient infrastructure.
Built on the Cisco Catalyst 6800 Series platform and compatible with Cisco Catalyst 6500 Series deployments, the C6840-X-1100W supports dual-stack IPv4/IPv6 hardware forwarding and comprehensive VLAN management with up to 4094 802.1Q tagged VLANs. Security is embedded through hardware ACLs, port security, 802.1X authentication, DHCP snooping, and Dynamic ARP Inspection, while high availability is assured via VSS-capable platform architecture with HSRP and VRRP support. Hardware-based QoS with traffic classification, DSCP marking, and scheduling ensures predictable application performance. Network management spans SNMP v1/v2c/v3, RMON, Cisco IOS CLI, Telnet, and SSH v2, with enhanced visibility through NetFlow, SPAN, and RSPAN traffic monitoring. IT procurement teams will appreciate the standards-based design aligned with IEEE 802.1Q, IEEE 802.3, IEEE 802.1X, and IEEE 802.3ad, plus support for link aggregation via LACP and PAgP.
Typical Enterprise Deployments
- Core and distribution layer switching in large campus networks requiring multi-protocol routing and high availability
