CISCO SYSTEMS SG500 X 48-Port Gigabit PoE Switch (SG500X48MPK9NA) Simple-to-use graphical interfaces reduce the time required to deploy, troubleshoot, and manage the network and allow you to support sophisticated capabilities without increasing IT head count. The switches also support Text view, a full command-line interface (CLI) option for partners that prefer it. Support for Simple Network Management Protocol (SNMP) allows you to set up and manage your switches and other Cisco devices remotely from a network management station, improving IT workflow and mass configurations. Extensive access control lists (ACLs) restrict sensitive portions of the network to keep out unauthorized users and guard against network attacks. Storm control can be applied to broadcast, multicast, and unknown unicast traffic.
