|
Layer 2 Switching |
|
Spanning Tree Protocol (STP) |
Standard 802.1d STP support
Fast convergence using 802.1w (Rapid Spanning Tree [RSTP]), enabled by default |
|
Port grouping |
Support for IEEE 802.3ad Link Aggregation Control Protocol (LACP): Up to 8 groups, Up to 8 ports per group with 16 candidate ports for each (dynamic) 802.3ad link aggregation |
|
VLAN |
Support for up to 256 VLANs simultaneously
Port-based and 802.1Q tag-based VLANs
Management VLAN
Guest VLAN |
|
Auto voice VLAN |
Voice traffic is automatically assigned to a voice-specific VLAN and treated with appropriate levels of QoS |
|
QinQ VLAN |
VLANs transparently cross a service provider network while isolating traffic among customers |
|
Generic VLAN Registration Protocol (GVRP) and Generic Attribute Registration Protocol (GARP) |
Protocols for automatically propagating and configuring VLANs in a bridged domain |
|
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. |
|
Automatic Media-Dependent Interface Crossover (MDIX) |
Automatically adjusts transmit and receive pairs if an incorrect cable type (crossover or straight-through) is installed. |
|
Security |
|
ACLs |
Drop or rate limit based on source and destination MAC, VLAN ID or IP address, 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
Support up to 512 rules |
|
Port security |
Creates the ability to lock source MAC addresses to ports; limits the number of learned MAC addresses |
|
IEEE 802.1X (authenticator role) |
802.1X: RADIUS authentication; guest VLAN; |
|
RADIUS, TACACS+ |
Supports RADIUS and TACACS authentication; switch functions as a client |
|
MAC address filtering |
Supported |
|
Storm control |
Broadcast, multicast, and unknown unicast |
|
DoS protection |
DOS attack prevention |
|
STP Bridge Protocol Data Unit (BPDU) Guard |
This security mechanism protects the network from invalid configurations. A port enabled for BPDU Guard is shut down if a BPDU message is received on that port |
|
Spanning Tree Loop Guard |
This feature provides additional protection against Layer 2 forwarding loops (STP loops). |
|
Secure Shell (SSH) Protocol |
SSH is a secure replacement for Telnet traffic. 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 |
|
Quality of Service |
|
Priority levels |
8 hardware queues |
|
Scheduling |
Strict priority and weighted round-robin (WRR)
Queue assignment based on differentiated services code point (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) |
|
Rate limiting |
Ingress policer, per VLAN and per port |
