Voice VLAN 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 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)
VLAN translation 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
Q-in-Q VLANs transparently cross over a service provider network while isolating traffic among customers
Selective Q-in-Q 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
GVRP/GARP Generic VLAN Registration Protocol (GVRP) and Generic Attribute Registration Protocol (GARP) enable automatic propagation and configuration of VLANs in a bridged domain
Unidirectional Link Detection (UDLD) 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
DHCP relay at Layer 2 Relay of DHCP traffic to DHCP server in a different VLAN. Works with DHCP option 82
IGMP (versions 1, 2, and 3) snooping 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 IGMP querier is used to support a Layer 2 multicast domain of snooping switches in the absence of a multicast router
HOL blocking Head-Of-Line (HOL) blocking
Loopback Detection 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
Layer 3
IPv4 routing Wirespeed routing of IPv4 packets Up to 7,168 routes and up to 256 IP interfaces
Wirespeed IPv6 static routing Up to 1,792 routes and up to 256 IPv6 interfaces
Layer 3 interface Configuration of Layer 3 interface on physical port, LAG, VLAN interface, or loopback interface
CIDR Support for classless interdomain routing
RIP v2 Support for Routing Information Protocol version 2 for dynamic routing
VRRP Virtual Router Redundancy Protocol (VRRP) delivers improved availability in a Layer 3 network by providing redundancy of the default gateway servicing hosts on the network. VRRP versions 2 and 3 are supported. Up to 255 virtual routers are supported
Policy-Based Routing (PBR) Flexible routing control to direct packets to different next hop based on IPv4 or IPv6 ACL
IP Service-Level Agreement (SLA) object tracking 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
DHCP server Switch functions as an IPv4 DHCP server serving IP addresses for multiple DHCP pools/scopes Support for DHCP options
DHCP relay at Layer 3 Relay of DHCP traffic across IP domains
User Datagram Protocol (UDP) relay Relay of broadcast information across Layer 3 domains for application discovery or relaying of BOOTP/DHCP packets
Stacking
Hardware stack Up to 8 units in a stack. Up to 400 ports managed as a single system with hardware failover
High availability Fast stack failover delivers minimal traffic loss. Support link aggregation across multiple units in a stack
Plug-and-play stacking configuration/ management Master/backup for resilient stack control Autonumbering Hot swap of units in stack Ring and chain stacking options, auto stacking port speed, flexible stacking port options
High-speed stack interconnects Cost-effective high-speed 10G fiber and copper interfaces. Support LAG as stacking interconnects for even higher bandwidth
Security
SSH SSH is a secure replacement for Telnet traffic. SCP also uses SSH. SSH versions 1 and 2 are supported
SSL Secure Sockets Layer (SSL) encrypts all HTTPS traffic, allowing secure access to the browser-based management GUI in the switch
IEEE 802.1X (authenticator role) 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
IEEE 802.1X supplicant 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 Web-based authentication provides network admission control through web browser to any host devices and operating systems
STP BPDU Guard 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
STP Root Guard This prevents edge devices not in the network administrator’s control from becoming Spanning Tree Protocol root nodes
STP loopback guard Provides additional protection against Layer 2 forwarding loops (STP loops)
DHCP snooping 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
IP Source Guard (IPSG) 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
Dynamic ARP Inspection (DAI) 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
IP/MAC/Port Binding (IPMB) 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
Secure Core Technology (SCT) Makes sure 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 plaintext 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])
Private VLAN Private VLAN provides security and isolation between switch ports, which helps ensure that users cannot snoop on other users’ traffic; supports multiple uplinks
Port security Ability to lock source MAC addresses to ports and limit the number of learned MAC addresses
RADIUS/TACACS+ Supports RADIUS and TACACS authentication. Switch functions as a client
RADIUS accounting 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
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
ACLs Support for up to 2000 entries on SG550XG and SX550X models Support for up to 3000 entries on all other models Drop or rate limit based on source and destination MAC, VLAN ID or IPv4 or Pv6 address, IPv6 flow label, protocol, port, DSCP/IP precedence, TCP/User Datagram Protocol (UDP) source and destination ports, 802.1p priority, Ethernet type, Internet Control Message Protocol (ICMP) packets, Internet Group Management Protocol (IGMP) packets, TCP flag; ACL can be applied on both ingress and egress sides Time-based ACLs supported
