Sraswb.book : SIER_SW6.FM Page 7 Tuesday, June 30, 1998 12:20 PM Configuring the Switch IP Configuration Description IP Configuration The method the switch uses to acquire its IP service configuration. • DHCP/Bootp: The switch attempts to get its IP configuration or its complete configuration from a DHCP or Bootp server. • Manual: Enables you to manually enter the IP configuration into the next three fields. • Disabled: Network management access to the switch over IP is disabled.
Sraswb.book : SIER_SW6.FM Page 8 Tuesday, June 30, 1998 12:20 PM Configuring the Switch IP Configuration Configuring IP Address from the Switch Console You can use the console to manually configure an IP address, subnet mask, and a gateway IP address (if needed). Or, you can use DHCP/Bootp to configure IP from a DHCP or Bootp server. (To use the DHCP/Bootp option, you must also configure the DHCP or Bootp server accordingly.
Sraswb.book : SIER_SW6.FM Page 9 Tuesday, June 30, 1998 12:20 PM Configuring the Switch IP Configuration 2. Press [E] (for Edit). 3. Select the IP Config field and use the Space bar to select Manual. 4. Select the IP Address field and enter the IP address you want to assign to the switch. 5. Select the Subnet Mask field and enter the subnet mask for the IP address. 6. If you want to reach off-subnet destinations, select the Gateway field and enter the IP address of the gateway router. 7.
Sraswb.book : SIER_SW6.FM Page 10 Tuesday, June 30, 1998 12:20 PM Configuring the Switch IP Configuration DHCP/Bootp Operation Overview The DHCP/Bootp switch configuration option is used to download configuration data from a DHCP or Bootp server to the switch. With DHCP you can have the switch automatically retrieve the IP address with no configuration required on either the switch or the DHCP server.
Sraswb.book : SIER_SW6.FM Page 11 Tuesday, June 30, 1998 12:20 PM Configuring the Switch IP Configuration DHCP Operation A significant difference between a DHCP configuration and a Bootp configuration is that an IP address assignment from a DHCP server is automatic, requiring no configuration of the DHCP server. Using that automatic feature, though, the address is temporarily leased. Periodically the switch is required to renew its lease of the IP configuration.
Sraswb.book : SIER_SW6.FM Page 12 Tuesday, June 30, 1998 12:20 PM Configuring the Switch IP Configuration An entry in the Bootp table file /etc/bootptab to tell the switch where to obtain a configuration file download would be similar to this entry: Configuring the Switch j3299switch:\ ht=ether:\ ha=080009123456:\ ip=11.22.33.44:\ sm=255.255.248.0:\ gw=11.22.33.1:\ lg=55.66.77.88:\ ts=11.22.33.55:\ T144=”switch.
Sraswb.book : SIER_SW6.FM Page 13 Tuesday, June 30, 1998 12:20 PM Configuring the Switch IP Configuration Configuring DHCP/Bootp In its default configuration, the switch is configured for DHCP/Bootp operation. However, if an IP address has previously been configured or if the IP Config parameter has been set to Disabled, then you will need to use this procedure to reconfigure the parameter to enable DHCP/Bootp operation.
Sraswb.book : SIER_SW6.FM Page 14 Tuesday, June 30, 1998 12:20 PM Configuring the Switch IP Configuration Globally Assigned IP Network Addresses Configuring the Switch If you intend to connect your network to other networks that use globally administered IP addresses, Hewlett-Packard strongly recommends that you use IP addresses that have a network address assigned to you.
