Insight Managed 28-Port and 52-Port Gigabit Ethernet Smart Cloud Switches
Delete Routes
 To delete one or more static routes:
1. Connect your computer to the same network as the switch.
You can use a WiFi or wired connection to connect your computer to the network, or
connect directly to a switch that is off-network using an Ethernet cable.
2. Launch a web browser.
3. In the address field of your web browser, enter the IP address of the switch.
If you do not know the IP address of the switch, see Access the Switch on page 13.
The login window opens.
4. Enter the switch’s password in the password field.
The default password is password. If you added the switch to a network on the Insight
app before and you did not yet change the password through the local browser interface,
enter your Insight network password.
The System Information page displays.
5. Select Routing > Routing Table > Route Configuration.
The Configure Routes page displays. The page also shows the Route Status section.
6. Select the check box next to each route to remove.
7. Click the Delete button.
The static route is deleted.
Configure ARP
The address resolution protocol (ARP) associates a layer 2 MAC address with a layer 3 IPv4
address. The switch support both dynamic and manual ARP configuration. With manual ARP
configuration, you can statically add entries into the ARP table.
ARP is a required part of the Internet protocol (IP) and is used to translate an IP address to a
media (MAC) address, defined by a local area network (LAN) such as an Ethernet network.
A device that must send an IP packet must learn the MAC address of the IP destination, or if
the destination is not on the same subnet, of the next hop router. The device achieves this by
broadcasting an ARP request packet, to which the intended recipient responds by sending an
ARP unicast reply that contains its MAC address. Once learned, the MAC address is used in
the destination address field of the Layer 2 header prepended to the IP packet.
The ARP cache is a table maintained locally in each device on the network. ARP cache
entries are learned by examining the source information in the ARP packet payload fields,
regardless of whether it is an ARP request or response. In this way, when an ARP request is
broadcast to all stations on a LAN segment or virtual LAN (VLAN), each recipient can store
the sender’s IP address and MAC address in its ARP cache. The ARP response, which is a
unicast reply, is normally detected only by the device that sends the ARP request. That
