| IPv4 and IPv6 dual stack | Coexistence 1280863 of both protocol stacks to ease migration |
| Firmware upgrade | Web browser upgrade (HTTP) and TFTP |
| Port Mirroring | Traffic on a port can be mirrored to another port for analysis with a network analyzer or RMON probe. Up to 4 source
ports can be mirrored to one destination port. A single session is supported. |
| VLAN mirroring | Traffic from a VLAN can be mirrored to a port for analysis with a network analyzer or RMON probe. Up to 4 source
VLANs can be mirrored to one destination port. A single session is supported. |
| DHCP (Options 66 and 67) | Dynamic Host Configuration Protocol (DHCP) options facilitate tighter control from a central point (DHCP server) to obtain IP address, auto-configuration (with configuration file download) |
| Text-editable config files | Config files can be edited with a text editor and downloaded to another switch, facilitating easier mass deployment |
| Smartports | Simplified configuration of QoS and security capabilities (available April 2011) |
