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 congurations 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 congurations are placed in /etc/dn/diag.
To install the package on the switch, use the dpkg --install <package_name> command.
