SSH is a secure replacement for Telnet traffic. Secure Copy (SCP) also uses SSH. SSH v1 and v2 are supported. |
IEEE 802.1X (authenticator role) |
RADIUS authentication, guest VLAN, single/multiple host mode, and single/multiple sessions |
STP loopback guard |
Provides additional protection against Layer 2 forwarding loops (STP loops) |
Secure Core Technology (SCT) |
Ensures that the switch will receive and process management and protocol traffic no matter how much traffic is received |
Secure Sensitive Data (SSD) |
A mechanism to manage sensitive data (such as passwords, keys, and so on) securely on the switch, populating this data to other devices and a secure auto-configuration. Access to view the sensitive data as plain text or encrypted is provided according to the user- configured access level and the access method of the user |
