Chassis Internal Network

Select MM Control → Chassis Int Network to manage internal connectivity between blade server ports and an internal advanced management module management port.

The Chassis Internal Network (CIN) provides internal connectivity between blade server ports and the internal advanced management module management port so that you can access the management module from a blade server by opening a WEB, CLI or SNMP session.

The communication path is two-way, so that the advanced management module also can use the services on the blade server, including LDAP, SMTP, DNS and NTP (Network Time Protocol).

Use the Chassis Internal Network (CIN) Status page to view the status of existing CIN elements.

CIN VLAN ID

The Virtual LAN (VLAN) ID that supports CIN.

CIN IP Address

The IP address that communicates on the CIN. An asterisk (*) after the address indicates that the address was dynamically assigned and is not explicitly configured by the user.

CIN MAC

The MAC address that is associated with the IP address.

Status

The CIN connection status. The following values are possible:

Operational: The advanced management module can ping the CIN IP address.
Not Operational: The advanced management module cannot ping the CIN IP address. Make sure that the blade server and the I/O module are configured correctly and that their configurations are compatible with the advanced management module. The CIN connection has a status of Not Operational if one of the following conditions exist:
- The blade server operating system must have an IP host route defined.
- The I/O modules already have a VLAN defined that contains the port for the blade server and the advanced management module.
Disabled: The CIN configuration has been disabled by an advanced management module administrator.

To find the management module from the blade server, you must assign one or more CIN VLAN IDs (CIN VID) on the Chassis Internal Network (CIN) Configuration page.

Each CIN interface to the advanced management module has an associated index number, ID, IP address, and action value.

CIN Index: This is an index of 1 through 14 to identify the CIN configuration.
CIN VLAN ID: This is a number 3 through 4094. These VLAN IDs cannot be the same as the one that is used for SOL/cKVM. A value of ~not used~ indicates that the configuration entry has not been defined. Click a VLAN ID to define the entry.
CIN IP Address: This is the IP address that is enabled to communicate on the CIN. A value of 0.0.0.0 (IPv4) or 0::0 (IPv6) indicates that any IP address can communicate on the CIN. In this case, the advanced management module listens on the CIN VLAN ID and learns the IP addresses dynamically. To restrict the addresses, define each IP address specifically. CIN entries cannot have matching IP addresses, with the exception of 0.0.0.0 (IPv4) or 0::0 (IPv6). Multiple CIN entries with an IP address of 0.0.0.0 (IPv4) or 0::0 (IPv6) are supported, provided that the VLAN IDs are different. The IP address of a CIN entry cannot be multicast or match the advanced management module IP address.
Action: Use this menu to enable, disable, or delete an existing CIN configuration.

Note: You can globally enable or disable CIN. When CIN is disabled, all CIN functions are disabled, even if index entries 1 through 14 are configured.

To create a new CIN VLAN configuration, click one of the ~not used~ entries; the Chassis Internal Network (CIN) Entry Definition page displayed.

Enter the VLAN ID and IP address; then, click Save to add the configuration to the existing CIN VLAN configurations, or click Cancel to return to the previous page.
