Packet-Capture Read - HPE FlexNetwork 7500 Series Command Reference Manual

Usage guidelines
To stop the capture while it is capturing packets, use the packet-capture stop command.
If you configure both the autostop filesize option and autostop duration option, the packet capture
stops when any one of the limits for the stop options is reached.
Follow these restrictions and guidelines to specify the URL, username, and password:
•
The URL format is
optional, for example,
configured with a port number, you must enter the port number in the URL.
•
If the server address is an IPv6 address, enclose the address in a pair of brackets, for example,
ftp://[2001::1]/test.cfg
•
You can also specify the DNS domain name for the server address field, for example,
ftp://sdp:21/test.cfg.
•
The username and password must be the same as those configured on the FTP server. If the
server authenticates only the username, the password can be omitted.
Do not set a short capturing duration in the autostop duration seconds option. If the duration is too
short, the capture might stop when a user has not logged in to the FTP server. The captured packets
cannot be saved because a packet file has not been created.
Examples
# Capture incoming packets and store the data in the database.pcap file on the FTP server at
10.1.1.1. The username and password for logging in to the FTP server are 1 and 1, respectively.
<Sysname> packet-capture local interface ten-gigabitethernet 1/0/1 write url
ftp://10.1.1.1/database.pcap username 1 password simple 1
