| Features | STP Bridge Protocol Data Unit (BPDU) Guard : This security mechanism protects the network from invalid configurations. A port enabled for BPDU Guard is shut down if a BPDU message is received on that port; Secure Shell (SSH) Protocol : SSH is a secure replacement for Telnet traffic. SCP also uses SSH. SSH v1 and v2 are supported; Flexible network management capabilities : Remote management. Using SNMP, you can set up and manage all switches and other Cisco devices in your network remotely. Command-Line Interface (CLI). The switches can be managed using a CLI. This capability can enable scripted or automated deployment for network professionals; Secure Sockets Layer (SSL) : SSL support: Encrypts all HTTPS traffic, allowing highly secure access to the browser-based management GUI in the switch |
