Displaying NIC Information and Statistics
Starting from NetVisor OS version 6.0.0, you can view the NIC information and packet statistics for management and rear-facing interfaces.
To view the switch NIC information, use the command: switch-nic-info-show.
CLI (network-admin@Leaf1) > switch-nic-info-show
|
switch-nic-info-show |
Display switch NIC information. |
|
name switch-nic-stats-list-name |
Specify the name of the interface. |
For example, to display the NIC information for the interface eth0, use the command:
CLI (network-admin@Leaf1) > switch-nic-info-show name eth0
name driver version firmware speed rxqnum txqnum rxqsize txqsize autoneg rxpause txpause
---- ------ ------- --------------- ----- ------ ------ ------- ------- ------- ------- -------
eth0 igb 5.4.0-k 3.25,0x800005cd 1000 4 4 4096 4096 on on off
The output displays the interface name, driver, version, firmware, speed, reception queue size, and transmitter queue size, among other details.
The switch-nic-stats-show command displays NIC statistics including the number of input packets, input bytes, output packets, output bytes, errors, and drops.
CLI (network-admin@Leaf1) > switch-nic-stats-show
|
switch-nic-stats-show |
Display switch NIC statistics. |
|
time date/time: yyyy-mm-ddTHH:mm:ss |
Specify the time to start statistics collection. |
|
start-time date/time: yyyy-mm-ddTHH:mm:ss |
Specify the start date and time for statistics collection. |
|
end-time date/time: yyyy-mm-ddTHH:mm:ss |
Specify the end date and time for statistics collection. |
|
duration duration: #d#h#m#s |
Specify the duration for statistics collection. |
|
interval duration: #d#h#m#s |
Specify the interval for statistics collection. |
|
since-start |
Displays statistics from the start. |
|
older-than duration: #d#h#m#s |
Displays statistics older than the specified date and time. |
|
within-last duration: #d#h#m#s |
Displays statistics within the specified duration. |
|
name switch-nic-stats-list name |
Specify the name of the interface. |
For example, to display the NIC statistics on eth0 interface within last 2 minutes, use the command:
CLI (network-admin@Leaf1) > switch-nic-stats-show name eth0 within-last 2m layout vertical

To display the statistics between a specified start-time and end-time, use the sample command:
CLI (network-admin@leaf1) > switch-nic-stats-show start-time 2020-07-21T05:00:00 end-time 2020-07-21T06:00:00 layout vertical

To modify the settings for statistics collection, use the command:
CLI (network-admin@Leaf1) > switch-nic-stats-settings-modify
|
switch-nic-stats-settings-modify |
Modify switch NIC statistics settings. |
|
Specify one or more of the following options: |
|
|
enable|disable |
Enable or disable statistics collection. |
|
interval duration : #d#h#m#s |
Specify the time interval to collect NIC statistics. The default value is 1 minute. |
|
disk-space disk-space-number |
Specify the disk-space allocated for statistics (including rotated log files). The default value is 50M. |
For example, use the command below to modify the interval for statistics collection:
CLI (network-admin@Leaf1) > switch-nic-stats-settings-modify interval 50s
To view the current settings, use the command:
CLI (network-admin@Leaf1) > switch-nic-stats-settings-show
switch: Leaf1
enable: yes
interval: 50s
disk-space: 50M
