4. Configuring Routing
The switch supports IP routing. Use the menus under the Routing tab to manage routing on
the system. This chapter contains the following sections:
•Configure IP Settings
•Configure VLAN Routing
•Configure and View Routes
•Configure ARP
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, the switch searches the host
table for a matching destination IP address. If an entry is found, the packet is routed to the
host. If there is not a matching entry, the switch performs a longest prefix match on the
destination IP address. If an entry is found, the packet is routed to the next hop. If there is no
match, the packet is routed to the next hop specified in the default route. If there is no default
route configured, 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
by a routing protocol. The host table can have entries added either statically by the
administrator or dynamically using ARP.
