Configuring IP Addressing
IP Configuration
Bootp Operation. When a Bootp server receives a request it searches its
Bootp database for a record entry that matches the MAC address in the Bootp
request from the switch. If a match is found, the configuration data in the
associated database record is returned to the switch. For many Unix systems,
the Bootp database is contained in the
/etc/bootptab file. In contrast to DHCP
operation, Bootp configurations are always the same for a specific receiving
device. That is, the Bootp server replies to a request with a configuration
previously stored in the server and designated for the requesting device.
Bootp Database Record Entries. A minimal entry in the Bootp table file
/etc/bootptab to update an IP address and subnet mask to the switch or a VLAN
configured in the switch would be similar to this entry:
j2610switch:\
ht=ether:\
ha=0030c1123456:\
ip=10.66.77.88:\
sm=255.255.248.0:\
gw=10.66.77.1:\
hn:\
vm=rfc1048
An entry in the Bootp table file
/etc/bootptab
to tell the switch or VLAN
where to obtain a configuration file download would be similar to this entry:
j2610switch:\
ht=ether:\
ha=0030c1123456:\
ip=10.66.77.88:\
sm=255.255.248.0:\
gw=10.66.77.1:\
lg=10.22.33.44:\
T144=”switch.cfg”:\
vm=rfc1048
where:
j2610switch 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, set this to 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.
