network --tcpdump [--port <nfs | windows | replication | ost | rds>] [--pkt_size <128 - 32768>] [--file_size <0 - 100>] [--stop] [--host <ip address list>] [--interface <bondN | ethN>]

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.
