Users Guide

You can change the VLAN settings, that is, move from a VLAN network to a non-VLAN network, or move from a non-VLAN
network to a VLAN network, only if Register with DNS is cleared.
By default, the IPv4 settings are enabled and the DNS registration is disabled with a default name. You can modify the name
using any local interfaces such as OpenManage Mobile.
NOTE: Ensure that the network cable is plugged to the correct port when you modify the VLAN state for the change to
be effective.
Isolate the chassis management from the data network as the uptime of a chassis that is improperly integrated into your
environment cannot be supported or guaranteed. Due to the potential of traffic on the data network, the management
interfaces on the internal management network can be saturated by traffic that is intended for servers. This results in OME–
Modular and iDRAC communication delays. These delays may cause unpredictable chassis behavior, such as OME–Modular
displaying iDRAC as offline even when it is up and running, which in turn causes other unwanted behavior. If physically
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.
Configuring chassis network services
The chassis network services configuration comprises 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 between 10 and 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 Community String.
4. 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.
5. Select the Idle Timeout in seconds and the Port Number. The port number can be between 10 and 65535.
6. 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:
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.
Configuring local access
To configure the local access settings in a chassis:
1. Click Devices > Chassis > View Details > Settings > Local Access Configuration.
The Local Access Configuration section is expanded.
2. Select Enable Chassis Power Button to use the power button to turn the chassis off or on.
3. Select the Quick Sync access type.
The available options are:
● Read-only—Enables read-only access to WiFi and Bluetooth Low Energy (BLE). You cannot write configuration
information using quick sync.
● Read-write—Enables writing configuration using quick sync.
● Disabled—Disables reading or writing configuration through quick sync.
4. Select Enable Inactivity Timeout to enable the idle timeout and enter the Timeout Limit.
NOTE: The Timeout Limit option is available only if the Enable Inactivity Timeout is selected.
