Cisco Catalyst 2960-X Series Switching Database Manager

Switching database manager (SDM) templates for LAN Base and IP Lite licenses allows the administrator to automatically optimize the ternary content-addressable memory (TCAM) allocation to the desired features based on deployment-specific requirements. MAC, routing, security, and QoS scalability numbers depend on the type of template used in the switch.

Cisco FlexStack-Plus

Cisco FlexStack-Plus provides stacking of up to eight 2960-X switches with the optional FlexStack-Plus module (Figure 2).

The FlexStack-Plus module is hot swappable and can be added to any Cisco Catalyst 2960-X or Catalyst 2960-XR with a FlexStack-Plus slot. Switches connected to a stack will automatically upgrade to the stack’s Cisco IOS Software version and transparently join the stack without additional intervention.

Cisco FlexStack-Plus and Cisco IOS Software offer true stacking, with all switches in a stack acting as a single switch unit. FlexStack-Plus provides a unified data plane, unified configuration, and single IP address for switch management. The advantages of true stacking include lower total cost of ownership and higher availability through simplified management as well as cross-stack features including EtherChannel, SPAN, and FlexLink.

To provide investment protection, FlexStack-Plus is backwards-compatible with FlexStack. Cisco Catalyst 2960-X LAN Base switches equipped with a FlexStack-Plus module can be stacked with Catalyst 2960-S and 2960-SF LAN Base switches equipped with a FlexStack module (see Table 5).
