Voice traffic is automatically assigned to a voice-specific VLAN and treated with appropriate levels of QoS. Auto voice capabilities deliver networkwide zero-touch deployment of voice endpoints and call control devices

Multicast TV VLAN allows the single multicast VLAN to be shared in the network while subscribers remain in separate VLANs. This feature is also known as Multicast VLAN Registration (MVR)

Support for VLAN One-to-One Mapping. In VLAN One-to-One Mapping, on an edge interface C-VLANs are mapped to S-VLANs and the original C-VLAN tags are replaced by the specified S-VLAN

VLANs transparently cross over a service provider network while isolating traffic among customers

Selective Q-in-Q is an enhancement to the basic Q-in-Q feature and provides, per edge interface, multiple mappings of different C-VLANs to separate S- VLANs
Selective Q-in-Q also allows configuring of Ethertype (TPID) of the S-VLAN tag
Layer 2 protocol tunneling over Q-in-Q is also supported

Generic VLAN Registration Protocol (GVRP) and Generic Attribute Registration Protocol (GARP) enable automatic propagation and configuration of VLANs in a bridged domain

UDLD monitors physical connection to detect unidirectional links caused by incorrect wiring or port faults to prevent forwarding loops and blackholing of traffic in switched networks

Relay of DHCP traffic to DHCP server in a different VLAN. Works with DHCP option 82

Internet Group Management Protocol (IGMP) limits bandwidth-intensive multicast traffic to only the requesters; supports 4K multicast groups (source-specific multicasting is also supported)

IGMP querier is used to support a Layer 2 multicast domain of snooping switches in the absence of a multicast router

Head-Of-Line (HOL) blocking

Loopback detection provides protection against loops by transmitting loop protocol packets out of ports on which loop protection has been enabled. It operates independently of STP

Wire speed routing of IPv4 packets
Up to 7,168 routes and up to 256 IP interfaces

Up to 1,792 routes and up to 256 IPv6 interfaces

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

Flexible routing control to direct packets to different next hop based on IPv4 or IPv6 ACL

IP SLA object tracking relies on IP SLA ICMP echo operation to detect connectivity to a certain network destination
IP SLA object tracking for VRRP provides a mechanism to track the connectivity to the VRRP router default route next hop
IP SLA object tracking for static routes provides a mechanism to track the connectivity to the destination network via the next hop specified in the static route

Switch functions as an IPv4 DHCP server serving IP addresses for multiple DHCP pools/scopes
Support for DHCP options

Relay of DHCP traffic across IP domains

Relay of broadcast information across Layer 3 domains for application discovery or relaying of BOOTP/DHCP packets

A mix of SF550X, SG550X, SG550XG, and SX550X in the same stack (10/100, Gigabit, and 10 Gigabit Ethernet)

SSH is a secure replacement for Telnet traffic. SCP also uses SSH. SSH versions 1 and 2 are supported

Secure Sockets Layer (SSL) encrypts all HTTPS traffic, allowing secure access to the browser-based management GUI in the switch

RADIUS authentication and accounting, MD5 hash, guest VLAN, unauthenticated VLAN, single/multiple host mode, and single/multiple sessions
Supports time-based 802.1X dynamic VLAN assignment

A switch can be configured to act as a supplicant to another switch. This enables extended secure access in areas outside the wiring closet (such as conference rooms)

Web-based authentication provides network admission control through web browser to any host devices and operating systems

A security mechanism to protect the networks from invalid configurations. A port enabled for Bridge Protocol Data Unit (BPDU) Guard is shut down if a BPDU message is received on that port. This avoids accidental topology loops

This prevents edge devices not in the network administrator's control from becoming Spanning Tree Protocol root nodes

Provides additional protection against Layer 2 forwarding loops (STP loops)

Filters out DHCP messages with unregistered IP addresses and/or from unexpected or untrusted interfaces. This prevents rogue devices from behaving as a DHCP server

When IP Source Guard is enabled at a port, the switch filters out IP packets received from the port if the source IP addresses of the packets have not been statically configured or dynamically learned from DHCP snooping. This prevents IP address spoofing

The switch discards ARP packets from a port if there are no static or dynamic IP/MAC bindings or if there is a discrepancy between the source or destination address in the ARP packet. This prevents man-in-the-middle attacks

The preceding features (DHCP Snooping, IP Source Guard, and Dynamic ARP Inspection) work together to prevent DoS attacks in the network, thereby increasing network availability

Makes sure that the switch will receive and process management and protocol traffic no matter how much traffic is received

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 plaintext or encrypted is provided according to the user-configured access level and the access method of the user

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])

Private VLAN provides security and isolation between switch ports, which helps ensure that users cannot snoop on other users' traffic; supports multiple uplinks

Ability to lock source MAC addresses to ports and limit the number of learned MAC addresses

Supports RADIUS and TACACS authentication. Switch functions as a client

The RADIUS accounting functions allow data to be sent at the start and end of services, indicating the amount of resources (such as time, packets, bytes, and so on) used during the session
