Secure and Efficient Network Management
The WS-C4948-E Cisco Catalyst 4948 supports secure and efficient network management through a variety of features and protocols.
One way it provides security is by supporting advanced security features such as access control lists (ACLs), which can be used to restrict access to the network based on specific criteria such as IP address or port number. Additionally, the switch also support features such as 802.1X authentication and Role-Based Access Control (RBAC) which allows to restrict access based on user roles.
Another way it provides security is by supporting various security protocols such as SSH, SSL, and SNMPv3 which encrypts the communication between the switch and the management station.
In terms of efficient network management, the WS-C4948-E Cisco Catalyst 4948 supports various management protocols such as Simple Network Management Protocol (SNMP), which allows for the monitoring and management of the switch through a network management system. The switch also supports Cisco's proprietary protocol, Cisco Discovery Protocol (CDP), which allows for the discovery and management of other Cisco devices on the network. Additionally, the switch also supports web-based management through a web interface, which allows for easy and intuitive management of the switch.
