| Security | Secure Sockets Layer (SSL)
SSL encrypts all HTTPS traffic, allowing secure access to the browser-based management GUI in the switch Secure Shell (SSH) Protocol 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) Remote Authentication Dial-In User Service (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 secure autoconfig. 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 Trustworthy systems Trustworthy systems provide a highly secure foundation for Cisco products Run-time defenses (Executable Space Protection [X-Space], Address Space Layout Randomization [ASLR], Built-In Object Size Checking [BOSC]) Port security Ability to lock source MAC addresses to ports and limit the number of learned MAC addresses RADIUS Supports RADIUS authentication for management access. Switch functions as a client. Storm control Broadcast, multicast, and unknown unicast DoS prevention Denial-of-Service (DoS) attack prevention Multiple user privilege levels in CLI Level 1, 7, and 15 privilege levels Access Control Lists (ACLs) Support for up to 512 rules Drop or rate limit based on source and destination MAC, VLAN ID or IPv4 or IPv6 address, IPv6 flow label, protocol, port, Differentiated Services Code Point (DSCP)/IP precedence, TCP/UDP source and destination ports, 802.1p priority, Ethernet type, Internet Control Message Protocol (ICMP) packets, IGMP packets, TCP flag; ACL can be applied on both ingress and egress sides Time-based ACLs supported |
