Gateway IP address
Gateway IP address is the IP address of the default subnet
gateway that allows the E5810B to communicate with
systems that are not on the local subnet. Thus, this is the
default subnet gateway where packets are sent and are
destined for a device not on the local subnet, as determined
by the subnet mask setting. Only one default subnet gateway
can be configured. A value of 0.0.0.0 indicates that no
subnetting is configured.
H
Hostname
Hostname is the Internet domain name for the E5810B.
Depending on the type of servers in the network, you may
be able to use this name to communicate with the E5810B.
However, since you can always use the IP address or the
name supplied by another server name, the hostname is not
a required configuration value.
You may enter up to 15 characters for the hostname. The
hostname must start with a letter and consists of upper and
lower case letters, digits, and dashes. The default hostname
is E5810- with the last four characters of the Ethernet (MAC)
address, such as E5810-e40c.
Hub
Hub is a common connection point for devices in a network.
Hubs are commonly used to connect segments of a LAN. A
hub contains multiple ports. When a packet arrives at one
port, it is copied to the other ports so that all the LAN
segments can see all the packets.
