ingress and egress packets on the specified port Enter the keyword direction then one of the packet directional indicators.
● rx: to monitor receiving packets only.
● tx: to monitor transmitting packets only.
● both: to monitor both transmitting and receiving packets.
flow-based enable — Specify flow-based enable for mirroring on a flow-by-flow basis and also for VLAN as source.
destination interface — Enter one of the following keywords and slot/port information.
NOTE:
● You cannot configure cascade ports as a destination port.
● For a 10–Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port information.
● For a 40–Gigabit Ethernet interface, enter the keyword fortyGigE then the slot/port information.
● For a port channel interface, enter the keyword port-channel then the port-channel id.
To display information on currently configured port-monitoring sessions, use the show monitor session command from
EXEC Privilege mode.
The following example monitors and displays information about port extender interface 255/0/0.

NOTE: Source as VLAN is achieved via Flow based mirroring.
In the following example, the host and server are exchanging traffic which passes through the uplink interface 1/1. Port 1/1 is
the monitored port and port 1/42 is the destination port, which is configured to only monitor traffic received on
tengigabitethernet 1/1 (host-originated traffic).
