Deleting a single file
The
‐
rm
option
can
be
used
to
delete
files
from
permanent
storage.
For
example,
to
remove
the
file
2011
‐
01
‐
01_00.00.52_dpcore.dump
,
the
command
would
be:
Device:/>
crashdump
‐
rm=2011
‐
01
‐
01_00.00.52_dpcore.dump
Deleting all files
All
crashdump
files
stored
in
memory
can
be
deleted
with
the
command:
Device:/>
crashdump
‐
rm=all
Instead
of
all
,
the
asterisk
character
(*)
can
also
be
used
as
a
wildcard:
Device:/>
crashdump
‐
rm=*
Important:
The
size
of
non
‐
volatile
memory
available
for
crashdump
file
storage
is
limited,
so
it
is
important
to
delete
crashdump
files
as
soon
they
have
been
downloaded.
Statistics
The
SEG
maintains
a
large
number
of
counters
in
memory
that
keep
track
of
system
activity.
This
information
is
kept
only
in
memory
and
is
mostly
made
up
of
single
numerical
values.
The
purpose
of
this
is
to
be
able
to
give
the
administrator
an
overview
of
the
tasks
being
performed
by
the
system.
The
counters
are
collectively
known
as
SEG
statistics.
A
separate
document
called
the
SEG
‐
100
Statistics
Reference
provides
a
detailed
listing
of
all
available
statistical
values.
This
section
is
designed
to
give
a
short
introduction
to
their
structure
and
use.
Accessing statistics
There
are
two
methods
for
the
administrator
to
view
SEG
statistics:
•
By
using
the
statistics
command
in
a
CLI
console.
•
Using
an
SNMP
client
in
conjunction
with
the
Clavister
MIB
file.
This
section
describes
examining
statistics
through
the
CLI.
SNMP
access
to
the
SEG
is
described
in
SNMP
monitoring
on
page
31
.
Hierarchical statistics structure
All
statistics
are
part
of
a
hierarchical
tree
structure
that
divides
them
into
related
values.
This
structure
can
be
clearly
seen
in
the
contents
of
the
Statistics
Reference
.
An
individual
statistic
is
identified
by
means
of
a
“path”
that
includes
everything
above
it
in
the
hierarchy.
The
form
of
this
path
is
described
in
the
Statistics
Reference
.
For
example,
the
path
definition
for
an
interface’s
bytes_in
statistic
is:
/ifaces/[..n]/bytes_in
Where
[..n]
represents
the
name
of
the
interface.
