4Motion 676 System Manual

Run the following command to enable port monitoring for a source or destination

interface:

npu(config)# monitor session { source interface <interface-type>

<interface-id> [{ rx | tx | both }] | destination interface

<interface-type > <interface-id>}

For example, to configure the Gigabit Ethernet 0/9 interface as the destination

interface, you can run the following command:

monitor session destination interface gigabitethernet 0/9

You can now run the following commands to mirror incoming traffic for the source

interfaces, Fast Ethernet 0/1 and Fast Ethernet 0/3:

npu(config)# monitor session source interface fastethernet 0/1 rx

npu(config)# monitor session source interface fastethernet 0/3 rx

All incoming and outgoing traffic for the 0/1 and 0/3 interfaces will be mirrored to

the 0/9 interface.

NOTE

For the current release, only one monitor session can be set up. This means that only one

destination can be configured for one or more source interfaces.

IMPORTANT

An error may occur if:

 The interface ID of the source or destination port you have specified is invalid. Refer

Table 3-39 for the interface ID corresponding to each interface type.

 The port specified as the source interface is already specified as the destination interface for

another port or vice versa.
