Usage Each switch maintains a set of standard flow-based statistics that are “always-on”, meaning that they are continuously tracked and updated by the switch. This command displays the TCP connections transiting the local switch as identified through the SYN/FIN protocol handshake between the client and the server of the application.
Examples To show the connection statistics for vnet MyVNET, use the following command:
CLI network-admin@switch > connection-show vnet MyVNET layout vertical
switch: pleiades24
vlan: 51
vxlan: 0
vnet:

connection-latency-show
This command is used to display latency information for connections on the switch. Comparing latency information for connections at various times can show whether the network performance has changed or stayed the same, and potentially eliminate the network as the cause of the problem
Syntax connection-latency-show
|
min high resolution time: #ns |
Displays the minimum latency in nanoseconds. |
|
max high resolution time: #ns |
Displays the maximum latency in nanoseconds. |
|
num-bins num-bins-number |
Specify the number of bins to divide the latency range. Bins display the number of connections at each latency interval. |
Defaults None

History Command introduced in Version 2.0.
Usage You can display all of the latency information about a connection or you can filter by the number of bins to display. Comparing latency information for connections at various times can show whether the network performance has changed or stayed the same, and potentially eliminate the network as the cause of the problem
