| Voice VLAN | Voice 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 VLAN | Multicast 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 VLAN | VLANs transparently cross a service provider network while isolating traffic among customers |
| Other | GVRP/GARP, UDLD, DHCP, IGMP, IGMP Querier, HQL booking, Loopback Detection, Jumbo frames |

| Layer 3 Interface | Configuration of Layer 3 interface on physical port, LAG, VLAN interface, or loopback interface |
| DHCP relay at Layer 3 | Relay of DHCP traffic across IP domains |
| User Datagram Protocol (UDP) relay | Relay of broadcast information across Layer 3 domains for application discovery or relaying of bootP/DHCP packets |
| DHCP Server | Switch functions as an IPv4 DHCP server serving IP addresses for multiple DHCP pools/scopes Support for DHCP options |
| Security | |
| 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 |
| 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 authentication | Web based authentication provides network admission control through web browser to any host devices and operating systems |
| STP Bridge Protocol Data Unit (BPDU) Guard | A 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 Guard | This prevents edge devices not in the network administrator’s control from becoming Spanning Tree Protocol root nodes |
| DHCP snooping | Filters out DHCP messages with unregistered IP addresses and/or from unexpected or untrusted interfaces. This prevents rogue devices from behaving as DHCP Servers |
| Support | IP 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 security | The ability to lock source MAC addresses to ports and limits the number of learned MAC addresses |

| 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 budgets | Switches 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: 185W Number of Ports That Support PoE: 24 |
| PoE powered device and PoE passthrough | In 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 |
