Use the Restart Mode pull-down menu to select one of the two switch operation modes: Layer 2,
Support IEEE 802.1Q VLANs and IP Routing, Support IEEE 802.1Q VLANs.

Menu Changes with Switch Operating Mode
Once the switch is configured for IP Routing (Layer 3 Switching), and rebooted, the Web Manager menu
adds some functions compared to the Layer 2 Only mode.
Switch Settings
The Switch Settings menu allows for various functions − some of which are configured on different
console screens − to be enabled or disabled on the switch (globally), without altering the individual
function’s configuration. Thus, the Distance-Vector Multicast Protocol (DVMRP) is configured from the
Configuration → Multicasting → IP Multicasting → DVMRP Settings window, but can be enabled or
disabled from the Layer 3 IP Routing Protocol Settings window − without changing the DVMRP
configuration entered in the DVMRP Settings window.
Layer 2 Switch Settings
To access the Layer 2 Switch Settings window, click Layer 2 Switch Settings (Configuration →
Switch Settings).
