Operation DUMP 1-61
Software Release 2.0.1
C613-03018-00 REV A
DUMP
Syntax
DUMP [ADDR=address] [LEN=length] [SIZE={BYTE|LONG|WORD}]
[SPACE={SD|SP|UD|UP|UR}]
where:
■
address is the first address (in hexadecimal) to be dumped.
■ length is the number of bytes (in hexadecimal) to dump.
Description
This command displays the contents of the router’s memory. The block of
memory to be displayed is specified by the parameters ADDR, LEN and
SPACE. The parameter SPACE specifies which of the possible CPU address
spaces is to be dumped (Table 1-9 on page 1-61)
The SIZE parameter specifies whether the data should be displayed grouped as
BYTEs, LONGWORDs or WORDs. Note that LEN is always in bytes,
regardless of the value of SIZE.
If the LEN, SIZE or SPACE parameters are omitted then they default to the
value they had at the previous invocation of the command. If the ADDR
parameter is omitted it will increment to dump the block of memory
immediately following the block dumped by the previous invocation. If the
ADDR parameter is given without a value (e.g. just the string ADDR or
ADDR=) then it will dump the block of memory previously dumped.
It is possible to use this command to dump I/O devices. This may interrupt the
operation of the router. The DUMP command is provided mainly as a
diagnostic tool. It should not be needed for normal operation of the router.
A typical display is shown in Figure 1-6 on page 1-62. The left-hand column
shows the address of the data in each row. The next eight columns give the data
starting at the address for the next 16 bytes. The right-most column is an ASCII
representation of the data in the row, with non-printing characters represented
by a dot.
