http configures HTTP and HTTPS servers
snmp configures SNMP servers
auth configures authentication methods
and reset resets all protocols to the factory defaults.
The configure command supports the following sub-commands:
...

following table describes the settings that you can configure in the administrative shell.
| Install Installs an SSL certificate into the NetMRI system for HTTPS sessions. |
| Define the basic device Discovery device expiration period, which is the time period that elapses before NetMRI automatically re-discovers any given device in its database. The default is seven (7) days; |
| Determines whether the HTTP and HTTPS servers are activated in the NetMRI system. You can also enable or disable individual encryption protocols in the HTTPS suite. By default, NetMRI enables all protocol options. You must restart the services after making any changes, which consists of a full restart of NetMRI. |
| Define the NetMRI management IP address, which is the IP used to communicate with the appliance. Should you change this value, the system will require a restart and your current terminal session will lose connectivity. Exercise caution when using this commandfull restart of NetMRI. |
| Starts the configuration for standalone NetMRI and Operations Center Controllers and Collectors. During this configuration, you specify network name, NetMRI server name, domain name, time server, time zone, NetMRI IP address and subnet mask, and several other basic operating parameters. | ||
| Enable Enables or disable disables support for specific SNMP protocol types, define and defines the community string and the SNMP passphrase. | ||
| Define Defines basic settings for SSH client and NetMRI SSH server, including enabling or disabling of either communications protocol and the type or types of encryption protocols supported by each. Under most circumstances, the defaults should be retained unless organization policy requires specific settings. You must restart the services after making any changes. | ||
or
| Initiates configuration of an appliance that is licensed as an Operations Center Controller (after running license and configure server) to set up or reset VPN components and allow Collectors to communicate with the Controller. configure tunserver or configure tunclient must be performed before Collectors can register with the Controller. For more information, see Infoblox Deployment Guide for NetMRI and Operations Center. | ||
reset | Resets all systems to the factory default. |
connect command
Use the connect command to connect to the command-line interface of a discovered device using the internal functionality of NetMRI.
...
Use the grep command to search a file for a particular pattern of characters. The command displays all lines that contain that pattern. By default, the pattern is a regular expression.
The following is the command syntax:
grep [options] pattern [files]
Example:
