Isolates a variety of networking issues that you might encounter while running a DR Series system. When you can isolate a problem or issue to a specific cause, you can better understand and resolve it. The DR Series system CLI network --troubleshoot command and its options allow you to perform basic troubleshooting checks on the state of a DR Series system.

Description

NOTE: When entering the network --troubleshoot command string, the DR Series system checks and displays the current state for all of the --troubleshoot options. To limit the type of network troubleshooting check you want to display, define the command string to a specified check (or checks). For example, using network --troubleshoot --gateway, displays the status of the gateway for a DR Series system (for details, see network --troubleshoot [--gateway]).

network --troubleshoot --gateway --interface <bondN | ethN>

Description

Performs a basic troubleshooting on the current state of the gateway connected to the DR Series system.

Syntax

Result

network --troubleshoot [--show_active <NFS| CIFS|OST|NDMP|ISCSI|RDS>]

Description

Displays the current network activity for NFS,, , , , or RDS clients on a DR Series system (the example that follows shows).

Syntax

Result

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.
