Verbose mode Use the following steps to enable and set the verbose level. 1 Set the Verbose level with a value of 0 to 3 using bits 4 and 5 of the EDA control reg (0x55). For example, to set the verbose level to 2, set bit 5 to 1 (5=1) and bit 4 to 0 (4=0). root@dellemc-diag-os:~# nvramtool --write --reg=0x55 --val=0x25 The value is written in hexadecimal. The xx10x1xx shows the bit positions of 2, 4&5, and bit 0 on the right. 2 Enable Verbose mode by setting bit 2 of the same reg to 1. NOTE: If you disable Verbose mode, or bit 2 of reg 0x55 is set to 0, the default verbosity level is 0/zero. EDA control reg (0x55): • 5:4-EDA Verbose Level = 0/1/2/3 or verbosity level 0, 1, 2, or 3. • 3-EDA Extended Tests • 2-EDA Verbose Mode = 0/1 (0=disabled; 1=enabled) • 1-EDA Stop on Error • 0-EDA Enable NOTE: If you do not need the Verbose mode settings to persist through reboots, you can use the environment variable method to enable Verbose Mode. export VERB_LEVEL= To clear the environment variable, use the unset VERB_LEVEL command.

Verbose mode
Use the following steps to enable and set the verbose level.
1
Set the Verbose level with a value of 0 to 3 using bits 4 and 5 of the EDA control reg (0x55).
For example, to set the verbose level to 2, set bit 5 to 1 (
5=1
) and bit 4 to 0 (
4=0
).
root@dellemc-diag-os:~# nvramtool --write --reg=0x55 --val=0x25
The value is written in hexadecimal. The
xx10x1xx
shows the bit positions of 2, 4&5, and bit 0 on the right.
2
Enable Verbose mode by setting bit 2 of the same reg to
1
.
NOTE:
If you disable Verbose mode, or bit 2 of reg 0x55 is set to
0
, the default verbosity level is
0/zero
.
EDA control reg (0x55):
•
5:4—EDA Verbose Level = 0/1/2/3 or verbosity level 0, 1, 2, or 3.
•
3—EDA Extended Tests
•
2—EDA Verbose Mode = 0/1 (0=disabled; 1=enabled)
•
1—EDA Stop on Error
•
0—EDA Enable
NOTE:
If you do not need the Verbose mode settings to persist through reboots, you can use the environment variable method to
enable Verbose Mode.
export VERB_LEVEL=<setting 0,1,2 or 3>
To clear the environment variable, use the
unset VERB_LEVEL
command.
Diagnostic package
The diagnostic applications, libraries, and
configurations
are packaged in a debian package called
dn-diags-{PLATFORM}-
{PACKAGE_VERSION}.deb
.
Executables are placed in
/opt/ngos/bin
, libraries are placed in
/opt/ngos/lib
, and
configurations
are placed in
/etc/dn/diag
.
To install the package on the switch, use the
dpkg --install <package_name>
command.
