cin command

This command can be used to view and configure the chassis internal network for up to 14 supported chassis internal network (CIN) configurations, globally, or for specified entries. You can define a CIN by creating a pool of VLAN (virtual local area network) ID/IP address pairs, each of which is a CIN entry.

If command syntax is not correctly entered, or if a command fails to run, an error message is returned. See Common errors for a list of error messages that apply to all commands or cin command errors for a list of error messages that are specific to the cin command.

Table 1. cin command.
The command table is a multi-row, four-column table where each row describes a CMM CLI command option: column one lists command function, column two provides a detailed command description, column three shows command-option syntax, and column four lists valid command targets.
Function	What it does	Command	Target (see paths in Command targets)
Display CIN configuration table	Displays the configuration table for the chassis internal network. Possible return values are: Global CIN enabled or disabled status CIN index VLAN ID IP address index entry enabled or disabled status	`cin`	Lenovo Flex System chassis: system
Set global CIN state	Sets the global state of CIN to enabled or disabled.	`cin -global -en` state where state is `on` `off` This command can only be run by users who have one or more of the following command authorities: Supervisor Chassis account management and chassis configuration See Commands and user authority for additional information.	Lenovo Flex System chassis: system
Clear all CIN configuration entries	Deletes all CIN configuration entries.	`cin all -clear` This command can only be run by users who have one or more of the following command authorities: Supervisor Chassis account management and chassis configuration See Commands and user authority for additional information.	Lenovo Flex System chassis: system
Turn all index entries on or off	Turns all CIN index entries on or off.	`cin all -en` state where state is `on` `off` This command can only be run by users who have one or more of the following command authorities: Supervisor Chassis account management and chassis configuration See Commands and user authority for additional information.	Lenovo Flex System chassis: system
Delete CIN configuration entry	Deletes the specified CIN configuration entry.	`cin` -entry_index`-clear` where entry_index is a number between 1 and 14 (inclusive). This command can only be run by users who have one or more of the following command authorities: Supervisor Chassis account management and chassis configuration See Commands and user authority for additional information.	Lenovo Flex System chassis: system
Set CIN configuration entry to enable or disable	Enables or disables a CIN configuration entry. If you attempt to enable or disable a non-existent entry, the action is ignored and no error message is returned.	`cin` -entry_index`-en` state where: entry_index is a number between 1 and 14, and state is `on` `off` This command can only be run by users who have one or more of the following command authorities: Supervisor Chassis account management and chassis configuration See Commands and user authority for additional information.	Lenovo Flex System chassis: system
Create a CIN configuration entry	Creates a CIN index entry. If the CIN index is currently empty, both -id and -ip must be specified. Note The VLAN ID must be different from that of the compute nodeCMM.	`cin` -entry_index -id vlan_id`-ip` ip_address where: entry_index is a number between 1 and 14, vlan_id is a VLAN ID number between 3 and 4094 (inclusive), ip_address is a valid IP address. This command can only be run by users who have one or more of the following command authorities: Supervisor Chassis account management and chassis configuration See Commands and user authority for additional information.	Lenovo Flex System chassis: system
Specify valid IP address for CIN index entry	Specifies the IP address of the CIN index entry. The CIN IP address must be a valid IP address. An error is displayed if the IP address is invalid. Note If the index is not empty, the IP address can be specified separately. CIN entries cannot have matching IP addresses unless they are 0.0.0.0. and have different VLAN IDs. If the CIN IP address is 0.0.0.0, the compute node IP address for CIN which is configured in the compute node operating system cannot be in the same subnet as that of the CMM. The IP address cannot be multi-cast and cannot match the IP address of the CMM.	`cin` -entry_index`-ip` ip_address where: entry_index is a number between 1 and 14 ip_address is a valid IP address. You can overwrite parameters of an existing definition; for example, cin -1 -ip 0.0.0.0 overwrites the current CIN IP address of the first cin entry. If the entry does not exist, an error is returned. This command can only be run by users who have one or more of the following command authorities: Supervisor Chassis account management and chassis configuration See Commands and user authority for additional information.	Lenovo Flex System chassis: system
Specify VLAN ID for CIN entry	Set the VLAN ID for the specified CIN entry. Note If the index is not empty, the ID can be specified separately. The VLAN ID must be different from that of the CMM.	`cin` -entry_index`-id` vlan_id where: entry_index is a number between 1 and 14 vlan_id is a number between 3 and 4094 (inclusive). This command can only be run by users who have one or more of the following command authorities: Supervisor Chassis account management and chassis configuration See Commands and user authority for additional information.
