NVRAM File Security
The Cisco CSR 1000v encrypts some of the disk partitions internal to the VM to provide extra security around
sensitive data that may be stored on the router. For example, information in NVRAM is encrypted so that it
is not visible to administrative entities with access to the physical hard disk that the Cisco CSR 1000v is stored
on.
You can search and filter the output of
show
and
more
commands. This functionality is useful if you need to
sort through large amounts of output or if you want to exclude output that you need not see.
To use this functionality, enter a
show
or
more
command followed by the
“
pipe
”
character ( | ); one of the
keywords
begin
,
include
, or
exclude
; and a regular expression on which you want to search or filter (the
expression is case sensitive):
showcommand
{
append
|
| begin
|
| exclude
|
| exclude
|
| include
|
| redirect
|
| section
|
| tee
}
regular-expression
show command
| {
append
|
begin
|
exclude | include
|
redirect
|
section
|
tee
}
regular-expression
The output matches certain lines of information in the configuration file.
To power off the Cisco CSR 1000v, you must power off the VM the router is installed on. For information
about powering off the VM, see your VM vendor documentation.
