monitor session source interface 
Description 
The  monitor session source  interface  command is used to configure the 
monitored port. To delete the corresponding monitored port, please use no 
monitor session source interface command. 
Syntax 
monitor session session_num  source  interface  {  fastEthernet  port-list | 
gigabitEthernet port-list | ten-gigabitEthernet port-list } mode 
no monitor session session_num  source  interface  {  fastEthernet  port-list | 
gigabitEthernet port-list | ten-gigabitEthernet port-list } mode 
Parameter 
session_num  ——  The monitor session number, the value of which is 1. 
port-list  ——  List of monitored port. It is multi-optional. 
mode  —— The monitor mode. There are three options: rx, tx and both. Rx 
(ingress monitoring mode), means the incoming packets received by the 
monitored port will be copied to the monitoring port. TX (egress monitoring 
mode), indicates the outgoing packets sent by the monitored port will be copied 
to the monitoring port. Both (ingress and egress monitoring), presents the 
incoming packets received and the outgoing packets sent by the monitored port 
will both be copied to the monitoring port.

User Guidelines 
1.  Monitored ports number is not limited, but it can’t be the monitoring port at 
the same time. 
2.  Whether the monitoring port and monitored ports are in the same VLAN or 
not is not demanded strictly. 
3.  The monitoring port and monitored ports cannot be link-aggregation 
member. 
Example 
Create monitor session 1, then configure Gigabit Ethernet port 4, 5, 7 as 
monitored ports and enable ingress monitoring: 
T3700G-28TQ(config)#monitor session 1 source interface gigabitEthernet 
1/0/4-5,1/0/7 rx
