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.
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
Description
Collects TCP/IP packet information based on a specific file size that you can configure (such as 3 Megabytes or MB).
|
NOTE: To stop the tcpdump process, use the DR Series system CLI network --tcpdump --stop command. |
Syntax
network --tcpdump --file_size 3
Result
Successfully started tcpdump, please use "network --tcpdump --stop" to stop.
For more information, see network --tcpdump [--port <nfs | windows | replication | ost>] [--pkt_size <128 - 32768>] [--file_size <0 - 100>] [--stop] [--host <ip address list>]
Description
Collects TCP/IP packet information based on a specific host IP address (for example, 10.10.11.12).
|
NOTE: To stop the tcpdump process, use the DR Series system CLI network --tcpdump --stop command. |
Syntax
network --tcpdump --host 10.10.11.12
Result
Successfully started tcpdump, please use "network --tcpdump --stop" to stop.
|
NOTE: You can also specify a number of host IP addresses using this command in a comma-delimited format (--host 10.10.11.12,10.12.12.13,10.10.12.14). |
