Chapter 1 Management VLAN Configuration

1.1 Introduction to Management VLAN

1.1.1 Management VLAN

To manage an Ethernet switch remotely through Telnet or network management, the
switch need to be assigned an IP address. As for a Quidway series Layer 2 Ethernet
switch, only the management VLAN interface can be assigned an IP address.
You can assign an IP address to a management VLAN interface in one of the following
three ways:
Using commands to assign IP addresses
Through BOOTP (In this case, the switch operates as a BOOTP client.)
Through dynamic host configuration protocol (DHCP) (In this case, the switch
operates as a DHCP client)
The three above mentioned ways are mutually exclusive. That is, the IP address
obtained in a new way overwrites the one obtained in the previously configured way
and the overwritten IP address is then released. For example, if you assign an IP
address to a VLAN interface by using the corresponding commands and then apply for
another IP address through BOOTP (using the ip address bootp-alloc command), the
former IP address will be removed, and the final IP address of the VLAN interface is the
one obtained through BOOTP.

1.1.2 Static Route

A static route is configured manually by an administrator. You can make a network with
relatively simple topology to operate properly by simply configuring static routes for it.
Configuring and using static routes wisely helps to improve network performance and
can guarantee bandwidth for important applications.
The disadvantages of static route lie in that: When a fault occurs or the network
topology changes, static routes may become unreachable, which in turn results in
network failures. In this case, manual configurations are needed to recover the
network.
To access an S3100 series Ethernet switch through networks, you can configure static
routes for it.
