Intercepts TCP/IP packets being transmitted or received over the network to which the DR Series system is attached.
You can filter the packets being collected by using the following options to the DR Series system CLI
network --tcpdump
command:
•
--port
by its type: NFS, CIFS, replication, OST, or RDS port
•
--pkt_size
by the packet size you specify
•
--file_size
by the file size you specify
•
--host
by the IP address (or addresses) that you specify
•
--interface
by the interface that you specify
The tcpdump files are collected on the DR Series system (in /store/tcpdump/), and they can be a valuable resource of
information about how your system and network interact. To stop collecting tcpdump files, use the DR Series system CLI
network --tcpdump --stop
command.
network --tcpdump [--pkt_size <128 - 32768>]
Description
Collects TCP/IP packet information based on a specific packet size (for example, 256 Kilobytes or KB).
NOTE:
To stop the tcpdump process, use the DR Series system CLI
network --tcpdump --stop
command.
