Power Dedicated to PoE -
Number of Ports That Support PoE -
Layer 2 Switching
MAC Table Up to 8192 MAC addresses
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
QinQ VLAN VLANs transparently cross a service provider network while isolating traffic among customers
GVRP and GARP Protocols for automatically propagating and configuring VLANs in a bridged domain
HOL HOL blocking prevention
Jumbo Frame Frame sizes up to 9216 supported
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; multiple host 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
SSH SSH v1 and v2 are supported
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
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
(IGMP) 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
IPv6 IPv6 host mode
IPv6 over Ethernet
IPv6/IPv4 Dual Stack
IPv6 neighbor and router discovery (ND)
IPv6 stateless address auto-configuration
Path maximum transmission unit (MTU) discovery
Duplicate address detection (DAD)
ICMP version 6
IPv6 ACL Drop or rate limit IPv6 packets in hardware
IPv6 QoS Prioritize IPv6 packets in hardware
(MLD v1/2) Snooping Deliver IPv6 multicast packets only to the required receivers
IPv6 Applications Web/SSL, Telnet server/SSH, DHCP Client, DHCP Autoconfig, CDP, LLDP
IPv6 RFCs Supported RFC 4443 (which obsoletes RFC2463) - ICMP version 6

configuration, system dashboard, system maintenance, and monitoring
Text-Editable Config
Config files can be edited with a text editor and downloaded to another switch, facilitating easier mass
Command line interface Scriptable CLI; a full CLI is supported. User privilege levels 1 and 15 are supported for the CLI
Cloud Services Support for Cisco Small Business FindIT Network Tool

IPv4 and IPv6 Dual Stack Coexistence of both protocol stacks to ease migration
Port Mirroring Traffic on a port or VLAN can be mirrored to another port for analysis with a network analyzer or RMON
probe. Up to 8 source ports can be mirrored to one destination port. Four sessions are supported.
