Creating an inactive flow in Flow Mirror
To create an inactive Flow Mirror flow, enter the flow --create flow_name -feature mirror
flow_parameters -noactive command.
The following example creates an inactive Flow Mirror flow named “mirroredflow120” from device
020a00 to device 01c000 ingressing through port 120.
switch:admin> flow --create mirroredflow120 -noactivate -feature mirror -ingrport
120 -srcdev 0x020a00 -dstdev 0x01c000
Refer to Activating Flow Mirror flows on page 80 for information on activating a Flow Mirror flow.
Activating Flow Mirror flows
To activate an inactive Flow Mirror flow, complete the following steps.
1. Connect to the switch and log in using an account with admin permissions.
2. Enter flow --activate flow_name -feature mirror.
The following example activates the Flow Mirror flow named “Flow1”.
switch:admin> flow --activate Flow1 -feature mirror
NOTE
Activating a Flow Mirror flow automatically clears all the flow statistics for that
flow.
Automatic activation of a Flow Mirror flow
Flow Mirror automatically activates a mirroring flow under the following conditions:
• On flow creation, unless the flow is created using the -noactivate keyword as part of the flow
command.
• On slot power-on, if the port specified is part of the slot being powered on and the flow was active
when the slot was powered off.
• On a High Availability (HA) failover, HA reboot, or a power cycle, if the flow was active when the HA
event occurred.
NOTE
Flow Mirror will not automatically re-activate a flow if the port types are other than Gen 5 (16 Gbps)
F_Ports or F_Port trunks.
Viewing Flow Mirror flows
