4.2.2 Login Password
The login password is required for remote console logins. The default login password is access. To
specify a new login password, use the Change Loginpass command and specify a new password
of up to six alphabetic characters.
Figure 4-3: Changing Login Password
NOTE: Default passwords may pose a security risk and should be changed as soon as possible.
This is especially true of the privileged password.
4.3 Protocol Configuration
4.3.1 IP Configuration
4.3.1.1 Subnet Mask
IP networks can be divided into several smaller networks by subnetting. When a network is
subnetted, some of the host part of each address is given to the network part of the address. The
amount is governed by the subnet mask. This mask allows the server to decide at connection time
whether a given TCP/IP host is part of the local network segment. All hosts must agree on the
subnet mask for a given network.
When the IP address is configured, a default subnet mask will be configured. If your network is
divided into subnetworks, you will need to create a custom subnet mask; the default subnet mask
will not be correct for your network. Use the Change Subnet Mask command.
Figure 4-4: Setting the Subnet Mask
4.3.1.2 Gateway
Usually, a TCP/IP internet is broken down into networks and subnetworks; a host is able to see
only the hosts on its own network. TCP/IP networks rely on routers, or gateways, to transfer
network traffic to hosts on other networks. Gateways are typically connected to two or more
networks and will pass or route TCP/IP packets across network boundaries.
The MSS can be told which hosts are the gateways for the local network. If no gateway is specified,
the MSS will listen to broadcasts on the network from other gateways to decide which hosts are
acting as gateways. The command below tells the MSS which host is the preferred gateway.
Figure 4-5: Specifying a Gateway
A secondary gateway can also be configured in case the primary gateway is unavailable. If you do
not wish to use a gateway, specify 0.0.0.0 as the IP address in the above command. See Change
Gateway
on page 6-10 for more information.
