Configuring Communication Services
This chapter includes the following sections:
Configuring HTTP
Procedure
Configuring SSH
Procedure
Step 1 In the Navigation pane, click the Admin tab. Step 2 On the Admin tab, click Communications Services. Step 3 In the Communications Services pane, click the Communication Services tab. Step 4 In the SSH Properties area, update the following properties:
Name Description SSH Enabled check box
Whether SSH is enabled on the CIMC.
SSH Port field
The port to use for secure shell access. The default is 22.
SSH Timeout field
The number of seconds to wait before the system considers an SSH request to have timed out.
Enter an integer between 60 and 10,800. The default is 1,800 seconds.
Max Sessions field
The maximum number of concurrent SSH sessions allowed on the CIMC.
This value may not be changed.
Active Sessions field
The number of SSH sessions currently running on the CIMC.
Step 5 Click Save Changes.
Configuring XML API
XML API for CIMC
The Cisco CIMC XML application programming interface (API) is a programmatic interface to CIMC for a C-Series Rack-Mount Server. The API accepts XML documents through HTTP or HTTPS.
For detailed information about the XML API, see Cisco UCS Rack-Mount Servers CIMC XML API Programmer’s Guide.
Configuring IPMI
IPMI Over LAN
Intelligent Platform Management Interface (IPMI) defines the protocols for interfacing with a service processor embedded in a server platform. This service processor is called a Baseboard Management Controller (BMC) and resides on the server motherboard. The BMC links to a main processor and other on-board elements using a simple serial bus.
During normal operations, IPMI lets a server operating system obtain information about system health and control system hardware. For example, IPMI enables the monitoring of sensors, such as temperature, fan speeds and voltages, for proactive problem detection. If server temperature rises above specified levels, the server operating system can direct the BMC to increase fan speed or reduce processor speed to address the problem.
Configuring IPMI over LAN
Procedure
Step 1 In the Navigation pane, click the Admin tab. Step 2 On the Admin tab, click Communications Services. Step 3 In the Communications Services pane, click the Communication Services tab. Step 4 In the IPMI over LAN Properties area, update the following properties:
Name Description Enabled check box
Whether IPMI access is allowed on this server.
Privilege Level Limit drop-down list
The highest privilege level that can be assigned to an IPMI session on this server. This can be one of the following:
- read-only—IPMI users can view information but cannot make any changes. If you select this option, IPMI users with the "Administrator", "Operator", or "User" user roles can only create read-only IPMI sessions, regardless of their other IPMI privileges.
- user—IPMI users can perform some functions but cannot perform administrative tasks. If you select this option, IPMI users with the "Administrator" or "Operator" user role can create user and read-only sessions on this server.
- admin—IPMI users can perform all available actions. If you select this option, IPMI users with the "Administrator" user role can create admin, user, and read-only sessions on this server.
Encryption Key field
The IPMI encryption key to use for IPMI communications.
Step 5 Click Save Changes.
Configuring SNMP
SNMP
The Cisco UCS C-Series Rack-Mount Servers support the Simple Network Management Protocol (SNMP) for viewing server configuration and status and for sending fault and alert information by SNMP traps. For information on Management Information Base (MIB) files supported by CIMC, see the MIB Quick Reference for Cisco UCS at this URL: http://www.cisco.com/en/US/docs/unified_computing/ucs/sw/mib/reference/UCS_MIBRef.html.
Configuring SNMP Properties
Procedure
Step 1 In the Navigation pane, click the Admin tab. Step 2 On the Admin tab, click Communications Services. Step 3 In the Communications Services pane, click the SNMP tab. Step 4 In the SNMP Properties area, update the following properties:
Name Description Enabled check box
Whether this server sends SNMP traps to the designated host.
Note After you check this check box, you need to click Save Changes before you can configure SNMP users or traps.
SNMP Port field
The port the server uses to communicate with the SNMP host.
This value cannot be changed.
Access Community String field
The default SNMP v1 or v2c community name or SNMP v3 username CIMC includes on any trap messages it sends to the SNMP host.
Enter a string up to 18 characters.
System Contact field
The system contact person responsible for the SNMP implementation.
Enter a string up to 64 characters, such as an email address or a name and telephone number.
System Location field
The location of the host on which the SNMP agent (server) runs.
Enter a string up to 64 characters.
Step 5 Click Save Changes.
What to Do Next
Configure SNMP trap settings as described in Configuring SNMP Trap Settings.
Configuring SNMP Trap Settings
Procedure
Step 1 In the Navigation pane, click the Admin tab. Step 2 On the Admin tab, click Communications Services. Step 3 In the Communications Services pane, click the SNMP tab. Step 4 In the Common Trap Destination Settings area, complete the following fields:
Name Description Trap Community String field
The name of the SNMP community group to which trap information should be sent.
SNMP Version drop-down list
The SNMP version and model used for the trap. This can be one of the following:
Type field
If you select V2 for the version, this is the type of trap to send. This can be one of the following:
Step 5 In the Trap Destinations area, complete the following fields:
Name Description ID column
The trap destination ID. This value cannot be modified.
Enabled column
For each SNMP trap destination that you want to use, check the associated check box in this column.
Trap Destination IP Address column
The IP address to which SNMP trap information is sent.
Tip To change the settings for a trap or to send a test trap message, administrators can click the trap row in the table.
Step 6 Click Save Changes.
Sending a Test SNMP Trap Message
Procedure
Step 1 In the Navigation pane, click the Admin tab. Step 2 On the Admin tab, click Event Management. Step 3 In the Event Management pane, click the Trap Settings tab. Step 4 In the Trap Destinations area, click the row of the desired SNMP trap destination. The Traps Details dialog box opens.
