network --tcpdump [--port <nfs | windows | replication | ost>] [--pkt_size <128 - 32768>] [--
file_size <0 - 100>] [--stop] [--host <ip address list>]
Intercepts TCP/IP packets being transmitted or received over the network to which the DR4000 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, or OST 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
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.
