This can be done in either of the following ways Manual You must input the information including IP address and subnet mask If your management station is not in the same IP subnet as the switch you will also need to specify the default gateway router Dynamic The switch sends IP configuration requests to BOOTP or DHCP servers on the network Note Only one VLAN interface can be assigned an IP address the default is VLAN 1 This defines the management VLAN the only VLAN through which you can gain management access to the switch If you assign an IP address to any other VLAN the new IP address overrides the original IP address and this becomes the new management VLAN Manual Configuration You can manually assign an IP address to the switch You may also need to specify a default gateway that resides between this device and management stations that exist on another network segment Valid IP addresses consist of four decimal numbers 0 to 255 separated by periods Anything outside this format will not be accepted by the CLI program Note The IP address for the switch is assigned via DHCP by default 1 7 SWITCH MANAGEMENT Before you can assign an IP address to the switch you must obtain the following information from your network administrator e IP address for the switch e Default gateway for the network e Network mask for this network To assign an IP address to the switch complete the following steps
