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

IGMP querier is used to support a Layer 2 multicast domain of snooping switches in the absence of a multicast router

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):

802.1X: RADIUS authentication and accounting, MD5 hash; guest VLAN; unauthenticated VLAN, single/multiple host mode and single/multiple sessions

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
