8 instances are supported
Multiple Spanning Tree instances using 802.1s (MSTP)
Port groupingSupport 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
VLANSupport for up to 4096 VLANs simultaneously
Port-based and 802.1Q tag-based VLANs
MAC-based VLAN
Management VLAN
Private VLAN Edge (PVE), also known as protected ports, with multiple uplinks
Guest VLAN
Unauthenticated VLAN
Dynamic VLAN assignment via RADIUS server along with 802.1x client authentication
CPE VLAN
Voice VLANVoice 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
Multicast TV VLANMulticast TV VLAN allows the single multicast VLAN to be shared in the network while subscribers remain in separate VLANs (also known as MVR)
Q-in-Q VLANVLANs transparently cross a service provider network while isolating traffic among customers

IPv4 routingWirespeed routing of IPv4 packets
Up to 1K static routes and up to 128 IP interfaces
IPv6 routingWirespeed routing of IPv6 packets
Classless Interdomain Routing (CIDR)Support for CIDR
Layer 3 InterfaceConfiguration of Layer 3 interface on physical port, LAG, VLAN interface, or loopback interface
DHCP relay at Layer 3Relay of DHCP traffic across IP domains
User Datagram Protocol (UDP) relayRelay of broadcast information across Layer 3 domains for application discovery or relaying of bootP/DHCP packets
DHCP ServerSwitch functions as an IPv4 DHCP server serving IP addresses for multiple DHCP pools/scopes
Support for DHCP options
Security
Secure Shell (SSH) ProtocolSSH 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
IEEE 802.1X (Authenticator role)802.1X: RADIUS authentication and accounting, MD5 hash; guest VLAN; unauthenticated VLAN, single/multiple host mode and single/multiple sessions
Supports time-based 802.1X
Dynamic VLAN assignment
Web-based authenticationWeb based authentication provides network admission control through web browser to any host devices and operating systems
STP Bridge Protocol Data Unit (BPDU) GuardA security mechanism to protect the network from invalid configurations. A port enabled for BPDU Guard is shut down if a BPDU message is received on that port
STP Root GuardThis prevents edge devices not in the network administrator’s control from becoming Spanning Tree Protocol root nodes
DHCP snoopingFilters out DHCP messages with unregistered IP addresses and/or from unexpected or untrusted interfaces. This prevents rogue devices from behaving as DHCP Servers
SupportIP Source Guard (IPSG), IP/MAC/Port Binding (IPMB), Secure Core Technology (SCT), Secure Sensitive Data (SSD), Layer 2 isolation Private VLAN Edge (PVE) with community VLAN
Port securityThe ability to lock source MAC addresses to ports and limits the number of learned MAC addresses
RADIUS/TACACS+Supports RADIUS and TACACS authentication. Switch functions as a client
Storm controlBroadcast, multicast, and unknown unicast
RADIUS accountingThe RADIUS accounting functions allow data to be sent at the start and end of services, indicating the amount of resources (such as time, packets, bytes, and so on) used during the session
DoS preventionDenial-Of-Service (DOS) attack prevention

Power over Ethernet (PoE)
802.3af PoE, 802.3at PoE+, and 60W PoE power are delivered over any of the RJ-45 ports within the listed power budgetsSwitches support 802.3at PoE+, 802.3af, 60W PoE, and Cisco prestandard (older) PoE. Maximum power of 60W to any 10/100 or Gigabit Ethernet port for PoE+ supported devices and 15.4W for PoE supported devices, until the PoE budget for the switch is reached. The total power available for PoE per switch is as follows:
Power Dedicated to PoE: 375W
Number of Ports That Support PoE: 24
PoE powered device and PoE passthroughIn addition to AC power, compact switch models can work as PoE powered devices and be powered by PoE switches connected to the uplink ports. The switch can also pass through the power to downstream PoE end devices if required
Maximum of 60W can be drawn per uplink port if the peer PoE switch supports 60W PoE. When multiple uplink ports are connected to PoE switches, the power drawn from these ports is combined
When AC power is connected and functioning properly, it will have priority over the PoE powered device function. The PoE powered device function will then act as a backup power source to the AC power. The PoE powered device function will be the primary power source for the switch if AC power is not connected
