White Papers

Enter the one of the following keywords and slot/port information:
• 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 extender (PE) Gigabit Ethernet interface, enter the keyword peGigE then the PEID/Unit/Port/ information.
• For a VLAN interface, enter the keyword VLAN then a vlan-id number. The range is from 1 to 4094.
NOTE: VLAN 4092 and VLAN 4093 are reserved VLANs. You cannot congure these
VLANs.
• For a remote VLAN interface, enter the keyword Remote-VLAN then a vlan-id number. The range is from 1 to 4094.
NOTE: VLAN 4092 and VLAN 4093 are reserved VLANs. You cannot congure these
VLANs.
• For a port channel interface, enter the keyword port-channel then the port-channel ID.
destination — Enter the keyword destination to specify the destination interface monitor ingress/egress or both ingress and
egress packets on the specied 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 ow-based enable for mirroring on a ow-by-ow basis and also for VLAN as source.
destination interface — Enter one of the following keywords and slot/port information.
NOTE
:
• You cannot congure 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 congured 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.
Dell(conf)#monitor session 1
source peGigE 255/0/0 destination TenGigabitEthernet 0/23 direction both
Dell(conf-mon-sess-0)#

NOTE
: Source as VLAN is achieved via Flow based mirroring.
In the following example, the host and server are exchanging trac 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 congured to only monitor trac received on tengigabitethernet 1/1 (host-originated
trac).
