This prevents rogue devices from behaving as DHCP servers IP Source Guard (IPSG) When IPSG 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 addresses in the ARP packet. This prevents man-in-the-middle attacks IP/MAC/port binding (IPMB) The preceding features (DHCP snooping, IPSG, and DAI) work together to prevent Denial-of-Service (DoS) attacks in the network, thereby increasing network availability Secure Core Technology (SCT) Makes sure that the switch will receive and

A port enabled for BPDU Guard is shut down if a BPDU message is received on that port. This avoids accidental topology loops STP Root Guard Prevents edge devices not in the network administrator’s control from becoming STP 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 DHCP servers IP Source Guard (IPSG) When IPSG 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 addresses in the ARP packet. This prevents man-in-the-middle attacks IP/MAC/port binding (IPMB) The preceding features (DHCP snooping, IPSG, and DAI) work together

Voice Services Discovery Protocol (VSDP) delivers 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 which customer VLANs (C-VLANs) on an edge interface are mapped to service provider VLANs (S-VLANs), and the original C-VLAN tags are replaced by the specified S-VLAN Q-in-Q VLANs transparently cross 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 the Ethertype (Tag Protocol Identifier [TPID]) of the S-VLAN tag Layer 2 protocol tunneling over Q-in-Q is also supported Generic VLAN Registration Protocol (GVRP)/Generic Attribute Registration Protocol (GARP) GVRP and GARP enable automatic propagation and configuration of VLANs in a bridged domain Unidirectional Link UDLD monitors physical connections to detect unidirectional links caused by incorrect Detection (UDLD) wiring or cable/port faults to prevent forwarding loops and blackholing of traffic in switched networks DHCP relay at Layer 2 Relay of DHCP traffic to a DHCP server in a different VLAN; works with DHCP Option 82 Internet Group Management Protocol (IGMP) versions 1, 2, and 3 snooping IGMP limits bandwidth-intensive multicast traffic to only the requesters; it supports 2000 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 IGMP proxy The IGMP proxy provides a mechanism for multicast forwarding based on IGMP membership information without the need for more complicated multicast routing protocols Head-of-Line (HOL) blocking HOL blocking prevention 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 Wire-speed routing of IPv4 packets Up to 990 static routes and up to 128 IP interfaces IPv6 routing Wire-speed routing of IPv6 packets Layer 3 interface Configuration of a Layer 3 interface on a physical port, LAG, VLAN interface, or loopback interface Classless Interdomain Routing (CIDR) Support for CIDR Routing Information Protocol (RIP) v2 Support for RIP v2 for dynamic routing Policy-Based Routing (PBR) Flexible routing control to direct packets to a different next hop based on an IPv4 or IPv6 Access Control List (ACL) DHCP server Switch functions as an IPv4 DHCP server, serving IP addresses for multiple DHCP pools or 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 Bootstrap Protocol (BOOTP)/DHCP packets Security Secure Shell (SSH) Protocol SSH is a secure replacement for Telnet traffic. Secure Copy Protocol (SCP) also uses SSH. SSH v1 and v2 are supported Secure Sockets Layer (SSL) SSL support: Encrypts all HTTPS traffic, allowing highly secure access to the browser-based management GUI in the switch IEEE 802.1X (authenticator role) 802.1X: 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, and MAC authentication 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 a web browser to any host devices and operating systems STP Bridge Protocol Data Unit (BPDU) Guard A security mechanism to protect the network from invalid configurations. A port enabled for BPDU Guard is shut down if a BPDU message is received on that port. This avoids accidental topology loops STP Root Guard Prevents edge devices not in the network administrator’s control from becoming STP 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 DHCP servers IP Source Guard (IPSG) When IPSG 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 addresses in the ARP packet. This prevents man-in-the-middle attacks IP/MAC/port binding (IPMB) The preceding features (DHCP snooping, IPSG, and DAI) work together to prevent Denial-of-Service (DoS) attacks in the network, thereby increasing network availability Secure Core Technol

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 a web browser to any host devices and operating systems STP Bridge Protocol Data Unit (BPDU) Guard A security mechanism to protect the network from invalid configurations. A port enabled for BPDU Guard is shut down if a BPDU message is received on that port. This avoids accidental topology loops STP Root Guard Prevents edge devices not in the network administrator’s control from becoming STP 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 DHCP servers IP Source Guard (IPSG) When IPSG 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 addresses in the ARP packet. This prevents man-in-the-middle attacks IP/MAC/port binding (IPMB) The preceding featur...

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 Classless Interdomain Routing (CIDR) Support for CIDR Dynamic Host Configuration Protocol (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 Bootstrap Protocol (BootP)/DHCP packets 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 QoS Priority levels 8 hardware queues Scheduling Strict priority and Weighted Round-Robin (WRR) queue assignment based on DSCP and class of service (802.1p/CoS) Class of service Port based; 802.1p VLAN priority based; IPv4/v6 IP precedence/Type of Service (ToS)/DSCP based; Differentiated Services (DiffServ); classification and re-marking ACLs, trusted QoS Rate limiting Ingress policer; egress shaping and rate control; per VLAN, per port, and flow based Congestion avoidance A TCP congestion avoidance algorithm is required to reduce and prevent global TCP loss synchronization Standards Standards IEEE 802.3 10BASE-T Ethernet, IEEE 802.3u 100BASE-TX Fast Ethernet, IEEE 802.3ab 1000BASE-T Gigabit Ethernet, IEEE 802.3ad Link Aggregation Control Protocol, IEEE 802.3z Gigabit Ethernet, IEEE 802.3x Flow Control, IEEE 802.3 ad LACP, IEEE 802.1D (STP), IEEE 802.1Q/p VLAN, IEEE 802.1w RSTP, IEEE 802.1s Multiple STP, IEEE 802.1X Port Access Authentication, IEEE 802.3af, IEEE 802.3at, RFC 768, RFC 783, RFC 791, RFC 792, RFC 793, RFC 813, RFC 879, RFC 896, RFC 826, RFC 854, RFC 855, RFC 856, RFC 858, RFC 894, RFC 919, RFC 920, RFC 922, RFC 950, RFC 951, RFC 1042, RFC 1071, RFC 1123, RFC 1141, RFC 1155, RFC 1157, RFC 1213, RFC 1215, RFC 1286, RFC 1350, RFC 1442, RFC 1451, RFC 1493, RFC 1533, RFC 1541, RFC 1542, RFC 1573, RFC 1624, RFC 1643, RFC 1700, RFC 1757, RFC 1867, RFC 1907, RFC 2011, RFC 2012, RFC 2013, RFC 2030, RFC 2131, RFC 2132, RFC 2233, RFC 2576, RFC 2616, RFC 2618, RFC 2665, RFC 2666, RFC 2674, RFC 2737, RFC 2819, RFC 2863, RFC 3164, RFC 3411, RFC 3412, RFC 3413, RFC 3414, RFC 3415, RFC 3416, RFC 4330 IPv6 IPv6 IPv6 host mode IPv6 over Ethernet IPv6/IPv4 Dual Stack IPv6 Neighbor Discovery (ND) IPv6 stateless address auto configuration Path Maximum Transmission Unit (MTU) discovery Duplicate Address Detection (DAD) Internet Control Message Protocol (ICMP) version 6 IPv6 over IPv4 network with Intrasite Automatic Tunnel Addressing Protocol (ISATAP) support USGv6 and IPv6 Gold Logo certified IPv6 QoS Prioritize IPv6 packets in hardware IPv6 ACL Drop or rate limit IPv6 packets in hardware Multicast Listener Discovery (MLD v1/2) snooping Deliver IPv6 multicast packets only to the required receivers IPv6 applications Web/SSL, Telnet server/SSH, Ping, Traceroute, Simple Network Time Protocol (SNTP), Trivial File Transfer Protocol (TFTP), Simple Network Management Protocol (SNMP), Remote Authentication D
