Con chassis network services, Use DHCPv6 to Obtain DNS Server Addresses

Page 26 highlights

● Enable Autoconfiguration ● IPv6 Address ● Prefix Length ● Gateway ● Use DHCPv6 to Obtain DNS Server Addresses ● Static Preferred DNS Server ● Static Alternate DNS Server NOTE: The static IPv6 IP address that is already configured is applied and displayed in OME-Modular when the configuration is changed from static to DHCP IP. 7. Enable or disable the VLAN for the chassis. You can configure the VLAN settings only if the Register with DNS check box is cleared. You can change 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 check box 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 are saturated by traffic that is intended for servers. It 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. 8. Click Apply to save the chassis network settings. 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 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. NOTE: The audit logs are not generated when the session expires based on idle timeout. 7. Select the SSH Port Number. The port number can be 10-65535. The default port number is 22. 8. Enable the remote RACADM session for the chassis. 26 Logging in to OME-Modular
