Layer 2 switching |
|||||||
MAC table |
Up to 8,192 MAC addresses |
||||||
Spanning Tree Protocol (STP) |
Standard 802.1d Spanning Tree support, enabled by default Fast convergence using 802.1w (Rapid Spanning Tree [RSTP]) Multiple Spanning Tree instances using 802.1s (MSTP) 16 instances are supported |
||||||
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
Load balance based on source and destination MAC address, or source and destination MAC/IP |
||||||
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 |
||||||
Jumbo frame |
Frame sizes up to 9216 supported |
||||||
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; Single-host, multiple-host, and multisession mode |
||||||
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 |
||||||
QoS |
|||||||
Priority levels |
8 hardware queues per port |
||||||
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), and 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 |
