| 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 | |
| Voice Lan: | |
| Voice traffic is automatically assigned to a voice-specific VLAN and treated with appropriate levels of QoS | |
| Generic VLAN Registration Protocol (GVRP)/ Generic Attribute Registration Protocol (GARP): | |
| Protocols for automatically propagating and configuring VLANs in a bridged domain | |
| Dynamic Host Configuration Protocol (DHCP) Relay at Layer 2: | |
| Relay of DHCP traffic to DHCP server in different VLAN. Works with DHCP Option 82 | |
| 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 (source-specific multicasting is also supported) | |
| IGMP querier is used to support a Layer 2 multicast domain of snooping switches in the absence of a multicast router | |
| Head-of-line (HOL) blocking: | |

Up to 32 static routes and up to 32 IP interfaces Classless Inter-Domain Routing (CIDR): Support for CIDR 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 |
| Security | Secure Shell Protocol (SSH): SSH secures Telnet traffic to and from the switch; 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): 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 | |
| Layer 3 isolation: Allow / disallow routing between IP subnets or directly connected IP networks | |
| Layer 2 isolation Private VLAN Edge (PVE) with community VLAN: PVE (also known as protected ports) provides Layer 2 isolation between devices in the same VLAN, supports multiple uplinks | |
| Port security: Locks 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 control: Broadcast, multicast, and unknown unicast | |
| DoS prevention: DoS attack prevention | |
| Congestion avoidance: | |
| A TCP congestion avoidance algorithm is required to minimize and prevent global TCP loss synchronization | |
| ACLs: Support for up to 512 rules | |
