Cisco Series: 2960XR Number of Ports: 24 Port Speed: Gigabit Layer: 3 Stackable: Optional PoE: No Software: IP Lite Uplinks: 4x 1Gb Cisco Catalyst 2960-XR models offer: ● Power resiliency with optional dual field-replaceable power supplies ● IP Lite Cisco IOS® software with dynamic routing and Layer 3 features Cisco Catalyst 2960-XR IP-Lite High-Performance Routing The Cisco hardware routing architecture delivers extremely high-performance IP routing in the Cisco Catalyst 2960-XR IP-Lite Switches: ● IP unicast routing protocols (Static, Routing Information Protocol Version 1 [RIPv1], and RIPv2, RIPng are supported for small-network routing applications. ● Advanced IP unicast routing protocols (OSPF for Routed Access) are supported for load balancing and constructing scalable LANs. IPv6 routing (OSPFv3) is supported in hardware for maximum performance. ● Equal-cost routing facilitates Layer 3 load balancing and redundancy across the stack. ● Policy-based routing (PBR) allows superior control by facilitating flow redirection regardless of the routing protocol configured. ● Hot Standby Routing Protocol (HSRP) and Virtual Router Redundancy Protocol (VRRP) provides dynamic load balancing and failover for routed links. ● Protocol Independent Multicast (PIM) for IP multicast is supported, including PIM sparse mode (PIM-SM), PIM dense mode (PIM-DM), PIM sparse-dense mode and Source Specific Multicast (SSM). The Catalyst 2960-XR switches support dual redundant power supplies. The Catalyst 2960-XR ships with one power supply by default. The second power supply can be purchased at the time of ordering the switch or as a spare. These power supplies have in-built fans to provide cooling.
