Configuring IP Addressing

 

IP Configuration

ip

is the IP address to be assigned to the switch (or VLAN).

sm

is the subnet mask of the subnet in which the switch (or VLAN) is installed.

gw

is the IP address of the default gateway.

lg

TFTP server address (source of final configuration file)

T144

is the vendor-specific “tag” identifying the configuration file to download.

vm

is a required entry that specifies the Bootp report format. For the switches

 

described in this guide, set this parameter to rfc1048.

The above Bootp table entry is a sample that will work for the switch when the appropriate addresses and file names are used.

Network Preparations for Configuring DHCP/Bootp

In its default configuration, the switch is configured for DHCP/Bootp opera­ tion. However, the DHCP/Bootp feature will not acquire IP addressing for the switch unless the following tasks have already been completed:

For Bootp operation:

A Bootp database record has already been entered into an appropriate Bootp server.

The necessary network connections are in place

The Bootp server is accessible from the switch

For DHCP operation:

A DHCP scope has been configured on the appropriate DHCP server.

The necessary network connections are in place

A DHCP server is accessible from the switch

Designating a primary VLAN other than the default VLAN affects the switch’s use of information received via DHCP/Bootp. For more on this topic, see the chapter on Virtual LANs in the Advanced Traffic Management Guide..

After you reconfigure or reboot the switch with DHCP/Bootp enabled in a network providing DHCP/Bootp service, the switch does the following:

Receives an IP address and subnet mask and, if configured in the server, a gateway IP address and the address of a Timep server.

If the DHCP/Bootp reply provides information for downloading a config­ uration file, the switch uses TFTP to download the file from the designated source, then reboots itself. (This assumes that the switch or VLAN has
