Users Guide

isolating the management network is impractical, the other option is to separate OME–Modular and iDRAC traffic to a
separate VLAN. OME–Modular and individual iDRAC network interfaces can be configured to use a VLAN.
NOTE: Any change in the attribute settings leads to IP drop or unavailability of the OME–Modular web interface for
some time. However, the OME–Modular web interface recovers automatically.

Configure chassis network services
The chassis network services configuration consists of SNMP, SSH, and remote RACADM settings.
To configure network services:
1. Click Devices > Chassis > View Details > Settings > Network Services.
The Network Services section is expanded.
2. In the SNMP Settings section, select the Enabled check box to enable the SNMP settings and select the Port Number.
The port number can be 10-65535.
NOTE: For SNMP operations, configure the timeout parameter on the client to facilitate successful completion of the
task. You may have to adjust the timeout parameter based on the network latency.
3. Enter the SNMP Community Name. The length of the community name must be less than or equal to 32 characters.
4. Download the Management Information Base (MIB) file to a local drive on your system.
5. In the SSH Settings section, select the Enabled check box to enable the SSH settings for the chassis and select the
maximum number of SSH sessions.
By default, a chassis can have a maximum number of four SSH sessions.
6. Select the Max Auth Retries to specify the number of retries when the SSH session fails. By default, the maximum number
of auth retries is three, which can be increased up to nine.
7. Select the Idle Timeout, in seconds, for which the SSH session can remain idle. The SSH session expires based on inactivity
timeout configuration, and the default idle timeout is 30 minutes. When there is a change in the chassis management
network, all active sessions that are listed on the User Sessions page are not terminated automatically.
The default value or minimum value for max
auth retries is three and the maximum value is nine.
NOTE: The audit logs are not generated when the session expires based on idle timeout.
8. Select the SSH Port Number. The port number can be 10-65535.
The default port number is 22.
9. Enable the remote RACADM session for the chassis.
You can view the remote RACADM option on the web interface only if you have the chassis administrator privilege.
NOTE:
A log for remote RACADM session (login or logout) is displayed in the Audit Logs page, irrespective of the
remote RACADM status. If the remote RACADM option is disabled, the feature does not work.
NOTE: Any change in the attribute settings leads to IP drop or unavailability of the OME–Modular web interface for
some time. However, the OME–Modular web interface recovers automatically.
10. Click Apply to save the chassis network services settings.
Configuring OME-Modular to use command line consoles
This section provides information about the OME-Modular command line consoles (serial or SSH
console) features. For details about setting up the system to perform systems management tasks
using the console, see the white paper, https://downloads.dell.com/manuals/all-products/esuprt_solutions_int/
esuprt_solutions_int_solutions_resources/servers-solution-resources_white-papers22_en-us.pdf. For information about using
RACADM commands in OME-Modular through the command line console, see Dell EMC OpenManage Enterprise Modular for
PowerEdge MX7000 Chassis RACADM Command Line Reference Guide.
