Layer 2 switching

VLAN

Support for up to 255 active VLANs simultaneously

Port-based and 802.1Q tag-based VLANs

Management VLAN

Guest VLAN

Voice VLAN

Voice traffic is automatically assigned to a voice-specific VLAN and treated with appropriate levels of QoS. Voice Services Discovery Protocol (VSDP) delivers networkwide zero-touch deployment of voice endpoints and call control devices

Layer 3 routing

IPv4 routing

Wire-speed routing of IPv4 packets

Up to 32 static routes and up to 16 IP interfaces

IPv6 routing

Wire-speed routing of IPv6 packets

Layer 3 interface

Configuration of Layer 3 interface on physical port, LAG, VLAN interface, or loopback interface

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
