Data Requirements

Item	Data	Description
Capturing packets on a specified interface	GigabitEthernet0/0/1	Capture packets on the interface GigabitEthernet0/0/1.
Capturing packets from the specified outer VLAN	10	Capture packets from VLAN 10.
Capturing packets matching the specified ACL	2003	Capture packets matching the ACL 2003.
Number of packets to be captured	120	Capture 120 packets.
Length of a single captured packet	55	Set the length of a single captured packet to 55 bytes.
Timeout interval of packet capture	10	Set the timeout interval of packet capture to 10 seconds.
Name of the file to which packets are saved	captureTest1.cap	Save the captured packets to the captureTest1.cap file.

Request Example

The specified VLAN and ACL must already exist, and the ACL must have the rules configured. For details about how to configure VLAN and ACL, see VLAN Management and ACL Rule Management separately.

Name of the file to which packets are saved cannot already exist.
