Setting the Switch’s IP Address (IP Version 4)
– 525
If there is no entry for an IP address in the ARP cache, the switch will broadcast an
ARP request packet to all devices on the network. The ARP request contains the
following fields similar to that shown in this example:
When devices receive this request, they discard it if their address does not match
the destination IP address in the message. However, if it does match, they write
their own hardware address into the destination MAC address field and send the
message back to the source hardware address. When the source device receives a
reply, it writes the destination IP address and corresponding MAC address into its
cache, and forwards the IP traffic on to the next hop. As long as this entry has not
timed out, the switch will be able forward traffic directly to the next hop for this
destination without having to broadcast another ARP request.
Also, if the switch receives a request for its own IP address, it will send back a
response, and also cache the MAC of the source device's IP address.
Setting the Switchs IP Address (IP Version 4)
This section describes how to configure an IPv4 interface for management access
over the network. This switch supports both IPv4 and IPv6, and can be managed
through either of these address types. For information on configuring the switch
with an IPv6 address, see “Setting the Switchs IP Address (IP Version 6)” on
page 529.
Configuring the IPv4
Default Gateway
Use the System > IP (Configure Global) page to configure an IPv4 default gateway
for the switch.
Parameters
These parameters are displayed:
Gateway IP Address
– IP address of the gateway router between the switch
and management stations that exist on other network segments. (Default: Not
configured)
An IP default gateway must be defined if the management station is located in
a different IP segment.
An IP default gateway can only be successfully set when a network interface
that directly connects to the gateway has been configured on the switch.
