2.5.1.Setting the System Operation Mode This switch can be set to operate as a Layer 2 switch, making all filtering and forwarding
decisions based strictly on MAC addresses. Or, it can be set to operate as a multilayer
routing switch, whereby it switches packets for all non-IP protocols (such as NetBUEI,
NetWare or AppleTalk) based on MAC addresses (see “Virtual LANs” on chapter 4), and
routes all IP packets based on the specified routing protocol. The System Mode menu is
shown below. Note that the switch will be automatically rebooted whenever the system
operation mode is changed.

Layer 2 Filtering and forwarding decision will be based on MAC addresses for all
protocol traffic.
Multilayer Switching based on MAC addresses will be used for all non-IP protocol
traffic, and routing will be used for all IP protocol traffic.
Note:
When the switch is set to multilayer mode, the IP menus are enabled, and the “IP
Configuration (Layer 2 Mode)” menu on chapter 2 is disabled. When operating in
multilayer mode, you should configure an IP interface for each VLAN that needs
to communicate with any device outside of the VLAN. (See “Subnet
Configuration” on chapter 2.)
2.5.2.Layer 2 Menu The Layer 2 menu contains options for port configuration, port mirroring, port trunking,
static unicast address configuration and static multicast address configuration. These
menu options are described in the following sections.
