4. Configuring Routing 4 The GS728TS, GS728TPS, GS752TS, and GS752TPS switches support IP routing. Use the links in the Routing menu to manage and monitor routing on the system. This section contains the following information: • Configuring IP Settings on page 160 • Configuring VLAN Routing on page 165 • Configuring Router Discovery on page 168 • Configuring and Viewing Routes on page 169 • Configuring ARP on page 171 When a packet enters the switch, the destination MAC address is checked to see if it matches any of the configured routing interfaces. If it does, then the silicon searches the host table for a matching destination IP address. If an entry is found, then the packet is routed to the host. If there is not a matching entry, then the switch performs a longest prefix match on the destination IP address. If an entry is found, then the packet is routed to the next hop. If there is no match, then the packet is routed to the next hop specified in the default route. If there is no default route configured, then the packet is passed to the software to be handled appropriately. The routing table can have entries added either statically by the administrator or dynamically via a routing protocol. The host table can have entries added either statically by the administrator or dynamically via ARP. Configuring IP Settings The pages available from the IP tab allow you to globally enable routing and view information about the packets received and transmitted by the switch. From the IP link, you can access the following pages: • IP Configuration on page 161 • IP Statistics on page 162 160

Configuring Routing
The GS728TS, GS728TPS, GS752TS, and GS752TPS switches support IP routing. Use the
links in the Routing menu to manage and monitor routing on the system. This section
contains the following information:

When a packet enters the switch, the destination MAC address is checked to see if it
matches any of the configured routing interfaces. If it does, then the silicon searches the host
table for a matching destination IP address. If an entry is found, then the packet is routed to
the host. If there is not a matching entry, then the switch performs a longest prefix match on
the destination IP address. If an entry is found, then the packet is routed to the next hop. If
there is no match, then the packet is routed to the next hop specified in the default route. If
there is no default route configured, then the packet is passed to the software to be handled
appropriately.
The routing table can have entries added either statically by the administrator or dynamically
via a routing protocol. The host table can have entries added either statically by the
administrator or dynamically via ARP.
Configuring IP Settings
The pages available from the IP tab allow you to globally enable routing and view information
about the packets received and transmitted by the switch. From the IP link, you can access
the following pages:
