Capacité de commutation 20 Gbps
Capacité de transfert 14.88 Mpps
Sécurité 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
RAM Buffer 1.5 Mbit
Fonction réseau Layer 2 switching
Spanning Tree Protocol (STP)
Standard 802.1d spanning tree support
Fast convergence using 802.1w (Rapid Spanning Tree Protocol [RSTP]), enabled by default
Multiple spanning tree instances using 802.1s (MSTP); 8 instances are supported
Per-VLAN Spanning Tree Plus (PVST+); 126 instances are supported
Rapid PVST+ (RPVST+); 126 instances are supported
Port grouping/link aggregation
Support for IEEE 802.3ad Link Aggregation Control Protocol (LACP)
Up to 4 groups
Up to 8 ports per group with 16 candidate ports for each (dynamic) 802.3ad Link Aggregation Group (LAG)
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. Auto voice capabilities deliver networkwide zero-touch deployment of voice endpoints and call control devices
Generic VLAN
Registration Protocol (GVRP) and Generic Attribute Registration Protocol (GARP)
Protocols for automatically propagating and configuring VLANs in a bridged domain
IGMP (versions 1, 2, and 3) snooping
Internet Group Management Protocol (IGMP) limits bandwidth-intensive multicast traffic to only the requesters; supports 255 multicast groups (source-specific multicasting is also supported)
IGMP querier
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 prevention
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 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
