|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
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
Support for up to 256 VLANs simultaneously
Port-based and 802.1Q tag-based VLANs
|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.|
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|
|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|
|Internet Group Management Protocol (IGMP) Versions 1, 2, and 3 Snooping||IGMP limits bandwidth-intensive multicast traffic to only the requesters; supports 256 multicast groups|
|IGMP querier||IGMP querier is used to support a Layer 2 multicast domain of snooping switches in the absence of a multicast router|
