GS748T Smart Switch
To configure the network information for the management interface:
1. Select the appropriate radio button to determine how to configure the network
information for the switch management interface:
• Dynamic IP Address (DHCP). Specifies that the switch must obtain the IP address
through a DHCP server.
• Dynamic IP Address (BOOTP). Specifies that the switch must obtain the IP address
through a BootP server.
• Static IP Address. Specifies that the IP address, subnet mask, and default gateway
must be manually configured. Enter this information in the fields below this radio
button.
2. If you selected the Static IP Address option, configure the following network information:
• IP Address. The IP address of the network interface. The factory default value is
192.168.0.239. Each part of the IP address must start with a number other than zero.
For example, IP addresses 001.100.192.6 and 192.001.10.3 are not valid.
• Subnet Mask. The IP subnet mask for the interface. The factory default value is
255.255.255.0.
• Default Gateway. The default gateway for the IP interface. The factory default value
is 192.168.0.254.
3. Specify the VLAN ID for the management VLAN.
The management VLAN is used to establish an IP connection to the switch from a
workstation that is connected to a port in the same VLAN. If not specified, the active
management VLAN ID is 1 (default), which allows an IP connection to be established
through any port.
When the management VLAN is set to a different value, an IP connection can be made
only through a port that is part of the management VLAN. It is also mandatory that the
port VLAN ID (PVID) of the port to be connected in that management VLAN be the same
as the management VLAN ID.
The management VLAN has the following requirements:
• Only one management VLAN can be active at a time.
• When a new management VLAN is configured, connectivity through the existing
management VLAN is lost.
• The management station should be reconnected to the port in the new management
VLAN.
Note: Make sure that the VLAN to be configured as the management
VLAN exists. And make sure that the PVID of at least one port that is
a port of the VLAN is the same as the management VLAN ID. For
information about creating VLANs and configuring the PVID for a
port, see VLANs on page 86.
