|
latency(us)high resolution time: #ns |
The network transmit time (latency) experienced by the connection in microseconds. |
|
obytes |
The number of bytes sent from the client side of the connection. |
|
ibytes |

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:
src-ip: 10.222.1.1
