Configuration restrictions and guidelines
This document provides examples for configuring Multitenant Device Contexts (MDCs) on a switch or an IRF fabric.
The MDC feature enables partitioning a physical device or an IRF fabric into multiple logical switches called "MDCs." These MDCs use their respective hardware and software resources, run independently of each other, and provide services for their respective customers. From the user's perspective, each MDC is a standalone device.
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 the MDC feature.
When you configure MDCs, follow these restrictions and guidelines:
· Only MPUs with 4-GB memory space support configuring MDCs.
· The MDC feature and the enhanced IRF feature (4-chassis IRF) are mutually exclusive.
As shown in Figure 1, a company has three departments:
· Information Technology Department holds the data center of the company. The data center has servers and storage devices.
· Finance Department has higher network availability and security requirements and needs a standalone network environment.
· Marketing Department has less traffic requirement.
The company has an H3C S12500 with three 48-port interface cards.
Configure MDCs on the switch to meet the network access requirements of the departments:
· Configure an MDC for each department to ensure service isolation:
? MDC A for Information Technology Department.
? MDC B for Finance Department.
? MDC C for Marketing Department.
· Assign resources to the MDCs to meet their service requirements:
? Allow MDC A, MDC B, and MDC C to use up to 60%, 50%, and 50% of the disk space on the MPUs, respectively.
? Allow MDC A, MDC B, and MDC C to use up to 70%, 60%, and 50% of the memory space on the MPUs and interface cards, respectively.
? Set the CPU weight to 5 for MDC C, and leave MDC A and MDC B to use the default CPU weight of 10.
This configuration example was created and verified on S12500-CMW710-R7129.
When you configure MDCs, follow these restrictions and guidelines:
· A standalone H3C S12500 supports up to three non-default MDCs.
· A non-default MDC starts to work only after you start it by using the mdc start command.
· The management Ethernet interface is shared by all MDCs. The other physical interfaces cannot be shared, and each of them can belong to only one MDC.
· To configure an interface assigned to an MDC, you must log in to the MDC.
· Due to hardware restrictions, the interfaces on some interface cards are grouped. The interfaces in a group must be assigned to or removed from the same MDC at the same time. You can figure out whether and how the interfaces are grouped by viewing the output of the allocate interface command or undo allocate interface command:
? If the interfaces you specified for the command belong to the same group or groups and you have specified all interfaces in the group or groups for the command, the command does not display any error information.
? Otherwise, the command displays the interfaces that failed to be assigned and the interfaces in the same group or groups.
1. Assign an IP address to the management Ethernet interface and enable the Telnet service to allow remote management of the default MDC.

As shown in Figure 2, a company has two departments:
· Information Technology Department holds the data center of the company. The data center has servers and storage devices.
· Finance Department has less traffic requirements, but it has higher network availability and security requirements and needs a standalone network environment.
The company has two H3C S12500 switches that form an IRF fabric. Each device has two 48-port interface cards.
Configure MDCs across the chassis to meet the network access requirements of the departments:
· Configure an MDC for each department to ensure service isolation:
? MDC A for Information Technology Department.
? MDC B for Finance Department.
· Assign resources to the MDCs to meet their service requirements:
? Allow MDC A and MDC B to use up to 60% and 50% of the disk space on the MPUs, respectively.
? Allow MDC A and MDC B to use up to 70% and 55% of the memory space on the MPUs and interface cards, respectively.
? Set the CPU weight to 6 for MDC B, and leave MDC A to use the default CPU weight of 10.
To allow traffic of MDC A and MDC B to be forwarded correctly between the member devices, each MDC must have at least one IRF link. H3C recommends that you establish two IRF links for each MDC to implement link backup and load balancing.
To avoid an IRF split, make sure there is at least one IRF link in up state between the members. If you assign a card that supports an IRF link to an MDC, the IRF link is disconnected. Figure 3 shows the correct configuration order. Figure 4 shows the incorrect configuration order.
Figure 3 Correct configuration order
|
1: Assign all interfaces on interface cards 2 and 4 to MDC A. |
2: Set up a new IRF link on MDC A. |
|
3: Assign all interfaces on interface cards 3 and 5 to MDC B. |
4: Set up a new IRF link on MDC B. |
Figure 4 Incorrect configuration order
|
1: Assign all interfaces on interface cards 2 and 4 to MDC A. |
2: Assign all interfaces on interface cards 3 and 5 to MDC B. |
This configuration example was created and verified on S12500-CMW710-R7129.
When you configure MDCs, follow these restrictions and guidelines:
· A non-default MDC starts to work only after you start it by using the mdc start command.
· The management Ethernet interface is shared by all MDCs. The other physical interfaces cannot be shared, and each of them can belong to only one MDC.
· To configure an interface assigned to an MDC, you must log in to the MDC.
· Due to hardware restrictions, the interfaces on some interface cards are grouped. The interfaces in a group must be assigned to or removed from the same MDC at the same time. You can figure out whether and how the interfaces are grouped by viewing the output of the allocate interface command or undo allocate interface command:
? If the interfaces you specified for the command belong to the same group or groups and you have specified all interfaces in the group or groups for the command, the command does not display any error information.
? Otherwise, the command displays the interfaces that failed to be assigned and the interfaces in the same group or groups.
· An IRF fabric formed by H3C S12500 switches supports up to three non-default MDCs.
· To configure both IRF and MDCs on devices, follow these steps:
a. Configure the devices to form an IRF fabric.
b. Create and configure MDCs.
c. Create IRF links on the MDCs.
If you configure MDCs before configuring IRF, the subordinate members will reboot and load the master's configuration rather than their own when they join the IRF fabric. None of the subordinate members' settings takes effect, except for the IRF port settings.
· The physical IRF ports of an IRF link must belong to the same MDC. Otherwise, the link cannot be set up, and a forwarding error might occur.
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 binding of the port with a physical port.
c. Assign the port to or reclaim the port from the MDC.
d. Use the save command to save the running configuration.
During this process, the IRF settings on the physical IRF ports will be lost and the IRF link will be disconnected. To avoid an IRF split, make sure there is at least one IRF link in up state at any time.
