XS728T ProSAFE 28-Port 10-Gigabit L2+ Smart Switch
IP
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.
From the IP link, you can access features described in the following sections:
• IP Configuration

The following table describes the fields displayed in this page:
Field Description
