Keep the following in mind when editing bootptab:
•The
<
hostname
>
definition can contain a maximum of 79 characters.
• The first character must be alphabetic.
• All characters must be alphanumeric.
• You can use a dot (.) to separate characters, but the character immediately
following the dot must be alphabetic.
• The hostname definition cannot contain an underscore.
Table 2-1
lists the tags for router host names. Table 2-2 lists the tags for boot
image names.
Table 2-1. BOOTPD Tags for a Router Host Name
Tag
Required or
Optional Value Example
ip Required IP address -- the host IP address
of the router.
ip=192.32.5.2
sm Optional Subnet mask -- the host subnet
mask of the router.
sm=255.255.255.0
T129 Required Pathname of the router
configuration file. The maximum
path length is 49 characters.
T129="/usr/cfg/
asn_Bost.cfg"
T130 Required Size of the router configuration file
in 512-byte blocks. The setting of
this tag determines how much
memory the router allocates for
the file. Set this tag to 0x0004.
T130=0x0004
tc Optional Table continuation -- pointer to a
definition in another location in the
same file for additional information.
The information this tag points to is
common to all routers that need to
boot using BOOTP. If information
in a definition for a specific router
is inconsistent with the definition
this tag points to, BOOTPD uses
the information for the specific
router.
tc=general
