Communication settings

Optimal parameter values depend on the characteristics of a network. In communication settings, you can type credentials, Ping (ICMP) Settings, and WS-Man Settings.

Table 1. Communication settingsThe following table describes the fields displayed in the Communication Settings page.
Field	Description
Credentials	You must specify the credentials to conduct discovery inventory. Credential information is not persistent across task executions.
Management Controller Username	Type the management controller user name. If using Active Directory authentication, enter username in the format domain\user name. NOTE The management controller login privilege is required to perform system inventory.
Management Controller Password	Type the management controller password.
Ping Settings (ICMP)
Require successful ping before attempting inventory	When enabled, a ping response is received from an address before attempting WS-Man inventory communications. This can improve the performance of the inventory process. However, disable this option if the network blocks ping requests. This option is enabled by default.
Retries	The number of times to reattempt a ping before excluding the system from inventory. The default is 3 retries, and the total allowed retries is 4.
Timeout	The time within which a ping response is received before the ping attempt fails. The default is 5 seconds.
WS-Man Settings	License Manager uses the management controller WS-Man interface to obtain inventory information.
Validate Certificate Name	If enabled, this ensures that inventory communications are conducted only with systems identifying themselves based on a certificate that matches the address used to communicate with that system. If the iDRAC certificate does not match the discovery address, disable certificate name validation for License Manager to communicate with the iDRAC. However, if the certificate name is not validated, License Manager cannot authenticate the identity of the remote system.
Validate Certificate Authority	If enabled, this ensures that the inventory communications are conducted only with systems identifying themselves based on a certificate issued by a trusted source. If the iDRAC certificate is not issued by a trusted authority, then disable validation for License Manager to communicate with the iDRAC. However, if the certificate authority is not validated, License Manager cannot authenticate the identity of the remote system. For validation, include a trusted certificate authority as part of the Trusted Root Certification Authorities list in Microsoft Windows. For more information, see the Microsoft Windows documentation.
Validate Certificate Revocation List	If enabled, this ensures that communications are not conducted with a system identifying itself by using a certificate that is revoked. If the management console cannot communicate with a certificate revocation list server, then disable this option for communicating with iDRAC. However, if the certificate revocation list is not validated, License Manager cannot authenticate the identity of the remote system.
Retries	The number of communication retry attempts made, if temporary WS-Man communication errors occur before the inventory attempt fails. The default is one retry, and the maximum allowed attempts is two.
Timeout	The time within which the WS-Man host must begin to return data before the communication attempt fails. The default value is 30 seconds.
Port	The HTTPS communication port configured on the iDRACs. The default port is 443. On this port, ensure that firewall settings allow the HTTPS communication between the management station and the iDRACs.
