Introduction

This document provides examples for configuring multitenant device contexts (MDCs) on the switch.

You can use H3C MDC technology to virtualize the switch into multiple logical devices called MDCs. Each MDC uses its own hardware and software resources, and operates and forwards packets independently. From the user's perspective, an MDC is a standalone physical device.

Prerequisites

The configuration examples in this document were created and verified in a lab environment, and all the devices were started with the factory default configuration. When you are working on a live network, make sure you understand the potential impact of every command on your network.

This document assumes that you have basic knowledge of H3C MDC.

General configuration restrictions and guidelines

When you configure MDCs, follow these general restrictions and guidelines:

·     You must install a valid license to use the MDC feature.

·     You can create MDCs only on MPUs with a memory space that is equal to or greater than 4 GB.

·     The enhanced IRF mode and the MDC feature are mutually exclusive.

·     A non-default MDC is not started by default. It runs only after you start it.

·     The management Ethernet interface is shared by all MDCs. Each of the other physical interfaces can belong only to one MDC. After you assign a physical interface to an MDC, you can configure the interface only after you log in to the MDC.

·     Because of hardware restrictions, the interfaces on some LPUs are grouped. The interfaces in a group must be assigned to or removed from the same MDC at the same time. To figure out whether and how the interfaces are grouped, view the output of the allocate interface or undo allocate interface command. If the following conditions are not met, the command displays the interfaces that failed to be assigned and the interfaces in the same group or groups:

¡     The interfaces specified for the command belong to the same group or groups.

¡     You have specified all interfaces in the group or groups for the command.

For example, an LPU has 48 interfaces. Interfaces 1 through 24 belong to one group, and interfaces 25 through 48 belong to another group.

Table 1 Interface assignment examples

Interfaces specified for the command	Result
1 through 10	The assignment failed. A message displays that interfaces 1 through 24 belong to the same group.
1 through 24 or 25 through 48	The assignment succeeded. The switch does not display any messages.
1 through 30	Interfaces 1 through 24 were assigned the MDC successfully. The assignment failed for interfaces 25 through 30. A message displays that interfaces 25 through 48 belong to the same group.
1 through 48	The assignment succeeded. The switch does not display any messages.

 

Example: Configuring MDCs in standalone mode

Network requirements

As shown in Figure 1, the switch has three LPUs. Each LPU has 48 Ethernet interfaces. The company has three departments:

·     The IT department is responsible for the data center. The data center has servers and storage devices.

·     The finance department has higher network availability and security requirements than the other departments.

·     The marketing department has less Internet traffic than the other departments.

Configure three MDCs on the switch as shown in Table 2 to meet the Internet access requirements of the three departments.

Table 2 CPU, disk space, and memory space quotas for MDCs

MDC	CPU weight	Disk space quota	Memory space quota
MDC A	10 (default)	60%	70%
MDC B	10 (default)	50%	60%
MDC C	5	40%	50%

Software version used

This configuration example was created and verified on S12500-CMW710-R7328P02.

Configuration restrictions and guidelines

When you configure MDCs, follow these restrictions and guidelines:

·     A standalone S12500 that uses LST1MRPNE1 or LST1MRPNE2 MPUs supports up to eight non-default MDCs.

·     A standalone S12500 that uses LST1MRPNC1 MPUs supports up to three non-default MDCs.

Example: Configuring MDCs in IRF mode

Network requirements

As shown in Figure 2, the IRF fabric has two members. Each member has two LPUs. Each LPU has 48 Ethernet interfaces. Two IRF links are established between the two members.

The company wants to use the IRF fabric to meet the Internet access requirements of two departments:

·     The IT department is responsible for the data center. The data center has servers and storage devices.

·     The finance department has higher network availability and security requirements but less Internet traffic than the IT department.

Configure two MDCs on the IRF fabric as shown in Table 3 to meet the Internet access requirements.

Table 3 CPU, disk space, and memory space quotas for MDCs

MDC	CPU weight	Disk space quota	Memory space quota
MDC A	10 (default)	60%	70%
MDC B	6	50%	55%

 

Figure 2 Network diagram

 

Requirements analysis

Both MDC A and MDC B are across chassis. To allow MDCs across chassis to forward traffic correctly, you must establish a minimum of one IRF link for each MDC. H3C recommends that you establish two IRF links for each MDC to implement redundancy and load sharing.

Assigning an LPU that has an IRF link established closes the IRF link. To avoid IRF fabric split, make sure a minimum of one IRF link is operating correctly during the configuration process, as shown in Figure 3.

Figure 3 Correct configuration order

1.     Assign all interfaces on LPUs 2 and 4 to MDC A.	2.     Establish a new IRF link on MDC A.
3.     Assign all interfaces on LPUs 3 and 5 to MDC B.	4.     Establish a new IRF link on MDC B.

 

Figure 4 Incorrect configuration order

1.     Assign all interfaces on LPUs 2 and 4 to MDC A.

2.     Assign all interfaces on LPUs 3 and 5 to MDC B.

 

Software version used

This configuration example was created and verified on S12500-CMW710-R7328P02.

Configuration restrictions and guidelines

When you configure MDCs, follow these restrictions and guidelines:

·     An IRF fabric that uses LST1MRPNE1 or LST1MRPNE2 MPUs supports up to eight non-default MDCs.

·     An IRF fabric that uses LST1MRPNC1 MPUs supports up to three non-default MDCs.

·     To configure both IRF and MDCs on a switch, configure IRF first. The switch will reboot and load the master's configuration rather than its own when it joins an IRF fabric as a subordinate member. None of its settings except for the IRF port settings will take effect. The IRF members in this example have been configured and have formed an IRF fabric.

·     The physical IRF ports of an IRF link must belong to the same MDC. If they do not, the link cannot be established and forwarding errors might occur, as shown in Figure 5.

Figure 5 The physical IRF ports of an IRF link must belong to the same MDC

 

·     To assign a physical IRF port to or reclaim a physical IRF port from an MDC , follow these steps:

a.     Use the shutdown command to shut down the port.

b.     Use the undo port group interface command to remove the IRF port-physical IRF port binding.

c.     Assign or reclaim the physical IRF port.

d.     Use the save command to save the running configuration.

To avoid IRF fabric split, make sure a minimum of one IRF link is operating correctly during this process.

Configuration procedures

1.     Assign an IP address to the management Ethernet interface for the IRF fabric. Configure Telnet service to allow remote management of the default MDC.

Verifying the configuration

1.     On the default MDC, identify whether the MDCs exist and are operating correctly.
