3Com 9100 manual Manually Configuring the IP Settings, Enable bootp vlan name all

Using Telnet 47

■Subnet address mask (optional)

The switch MAC address is found on the rear label of the switch.

Once this is done, the IP address and subnetwork mask for the switch will be downloaded automatically. You can then start managing the switch without further configuration.

You can enable BOOTP on a per-VLAN basis by using the following command:

enable bootp vlan [<name> all]

By default, BOOTP is enabled on the default VLAN.

If you configure the switch to use BOOTP, the switch IP address is not retained through a power cycle, even if the configuration has been saved. To retain the IP address through a power cycle, you must configure the IP address of the VLAN using the command-line interface, Telnet, or Web interface.

All VLANs within a switch that are configured to use BOOTP to get their IP address use the same MAC address. Therefore, if you are using BOOTP relay through a router, the BOOTP server must be capable of differentiating its relay based on the gateway portion of the BOOTP packet.

Manually Configuring the IP Settings

If you are using IP without a BOOTP server, you must enter the IP parameters for the switch in order for the SNMP Network Manager, Telnet software, or Web interface to communicate with the device. To assign IP parameters to the switch, you must do the following:

■Log in to the switch with administrator privileges.

■Assign an IP address and subnetwork mask to a VLAN.

The switch comes configured with a default VLAN named default. To use Telnet or an SNMP Network Manager, you must have at least one VLAN on the switch, and it must be assigned an IP address and subnetwork mask. IP addresses are always assigned to a VLAN. The switch can be assigned multiple IP addresses.

For information on creating and configuring VLANs, refer to Chapter 4.
