In the first example, the router was booted using TFTP over Ethernet. The message
indicates the method of booting, the line number, the CSR (Command and Status
Register) address, the IP address, the filename, the host, and the gateway.The
line
number
distinguishes one port from another on a multiport board. The
CSR address
(the first of the two values in parentheses) identifies which interface board slot was
used to boot the router.
The
IP address
listed after “as” (128.185.227.220 in this example) indicates which
IP address the router used as its own IP address. The
Filename
is the name of the
file that has the load image. The IP address listed after
Host
is the IP address of
the server where the file is stored. The
Gateway
, if listed, is the router that routes
the requests and responses between the server and the router that is booting.
Example 2:
boot
Manual Booted using Integrated Boot Device Loadname vl.ver1
In the second example, the router was booted manually using the Integrated Boot
Device (IBD).
Manual
indicates that the boot information was entered manually at
boot time.
Buffer
Use the buffer command to display information about packet buffers assigned to
each interface or range of interfaces.
Note: Each buffer on a device is the same size and is dynamically built. Buffers
vary in size from one device to another.
Todisplay information about one interface only, enter the interface or network
number as part of the command. Toobtain the interface number, use the GWCON
configuration command.
Syntax:
buffer [
network#
or
range_of_network#
]
Todisplay information about multiple interfaces, specify the range_of_network# (or
a combination of
network#
and
range_of_network#
). For example, specifying buffer
0 3 25-50 displays the information for nets 0, 3, and 25 through 50.
Example:
buffer Input Buffers: Buffer sizes:
Nt Interface Req Alloc Low Curr Hdr Wrap Data Trail Total Bytes Alloc
0 TKR/0 20 20 7 0 109 92 2052 7 2260 45200

2 PPP/1 10 10 4 0 108 92 2048 0 2248 22480
Nt Network interface number associated with the software.
Interface
Type of interface.
Input Buffers:
Req Number of buffers requested.
Alloc Number of buffers allocated.
