How to read IFSTAT counters on your AFF/FAS systems

Data ONTAP 7-mode

node_name> ifstat [ -z ] -a | <interface_name>

Clustered Data ONTAP 8 and ONTAP 9 

The command is executed from the Nodeshell of each node

cluster::> system node run -node <node_name> -command ifstat [ -z ] -a | <interface_name>

Output example

cluster::> system node run -node node_example> -command ifstat e0a

Note:

• The -z argument clears the statistics
• The -a argument displays statistics for all network interfaces including the virtual host and the loopback address. Optionally, you can leave off the -a argument and specify the name of a network interface.
