Description

Displays the current network activity for NFS, CIFS, OST, NDMP, iSCSI, or RDS clients on a DR Series system (the

example that follows shows CIFS).

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.

Syntax

network --tcpdump --pkt_size 256
