Default Gateway
The IP address for the default gateway. A gateway is a router or a dedicated
network device that enables the switch to communicate with devices in other
networks or subnetworks. The IP address should be part of the same subnet as
the switch IP address.
If all of your devices are in the same network and a default gateway is not used,
you do not need to enter an IP address in this field.
This setting is enabled only if the IP assignment mode is Static.
Note
You must specify a default gateway if your network management
station and the switch are in different networks or subnetworks.
Otherwise, the switch and your network management station will not
be able to communicate with each other.
The IP address and the default gateway cannot be the same.
Username
The name of a user who is authorized to access the device manager. The name
can have up to 64 alphanumeric characters and is not case sensitive. The name
cannot contain a ?, a space, or a tab.
You must enter a username if you enter a password. We recommend that you
provide a username-and-password pair to the switch to secure access to the
device manager.
After initial setup, you can add, delete, or modify username-and-password
pairs from the Users and Passwords window on the device manager. To display
this window, choose Configure > Users and Passwords from the device
manager menu. For more information, see the
“Control Access to the Switch”
section on page 3-11
.
Password
The password for the switch can have up to 25 alphanumeric characters, can
start with a number, is case sensitive, and allows embedded spaces. The
password cannot contain a ? or a tab and does not allow spaces at the beginning
or end.
We recommend that you provide a username-and-password pair to the switch
to secure access to the device manager.
After initial setup, you can add, delete, or modify username-and-password
pairs from the Users and Passwords window on the device manager. To display
this window, choose Configure > Users and Passwords from the device
manager menu. For more information, see the
