Configuring IP Addressing

IP Configuration

gw=10.66.77.1:\

lg=10.22.33.44:\

T144=”switch.cfg”:\

vm=rfc1048

where:

2520switch

is a user-defined symbolic name to help you find the correct section of the

 

bootptab file. If you have multiple switches that will be using Bootp to get their

 

IP configuration, you should use a unique symbolic name for each switch.

ht

is the “hardware type”. For the switches covered in this guide, enter ether (for

 

Ethernet). This tag must precede the ha tag.

ha

is the “hardware address”. Use the switch's (or VLAN's) 12-digit MAC address.

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. Use rfc1048 for the

 

switches covered in this guide.

N o t e

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
