Configuring ARP MAD
Before you configure ARP MAD, choose an ARP MAD link scheme as described in "ARP MAD."
As a best practice, connect the ARP MAD links after you finish the ARP MAD configuration if you are not using existing data links as ARP MAD links.
Configuring ARP MAD that uses common Ethernet ports
Configure ARP MAD on a VLAN interface if you use common Ethernet ports for ARP MAD.
When you configure ARP MAD that uses common Ethernet ports, follow these restrictions and guidelines:
Category | Restrictions and guidelines |
---|---|
ARP MAD VLAN |
|
ARP MAD and feature configuration | If an intermediate device is used, make sure the following requirements are met:
|
To configure ARP MAD that uses common Ethernet ports:
Step | Command | Remarks |
---|---|---|
1. Enter system view. | system-view | N/A |
2. Assign a domain ID to the IRF fabric. | irf domain domain-id | The default IRF domain ID is 0. |
3. Configure the IRF bridge MAC address to change as soon as the address owner leaves. | undo irf mac-address persistent | By default, the IRF bridge MAC address remains unchanged for 6 minutes after the address owner leaves. |
4. Create a VLAN dedicated to ARP MAD. | vlan vlan-id | The default VLAN on the device is VLAN 1. |
5. Return to system view. | quit | N/A |
6. Enter Ethernet interface view. | interface interface-type interface-number | N/A |
7. Assign the port to the ARP MAD VLAN. |
| The link type of ARP MAD ports can be access, trunk, or hybrid. The default link type of a port is access. |
8. Return to system view. | quit | N/A |
9. Create the VLAN interface and enter VLAN interface view. | interface vlan-interface vlan-interface-id | N/A |
10. Assign the interface an IP address. | ip address ip-address { mask | mask-length } | By default, no IP addresses are assigned to any VLAN interfaces. |
11. Enable ARP MAD. | mad arp enable | By default, ARP MAD is disabled. |
Configuring ARP MAD that uses management Ethernet ports
When you configure ARP MAD that uses management Ethernet ports, follow these restrictions and guidelines:
Category | Restrictions and guidelines |
---|---|
Management Ethernet ports for ARP MAD | Connect a management Ethernet port on each IRF member device to the common Ethernet ports on the intermediate device. |
ARP MAD VLAN | On the intermediate device, create a VLAN for ARP MAD, and assign the ports used for ARP MAD to the VLAN. On the IRF fabric, you do not need to assign the management Ethernet ports to the VLAN. |
ARP MAD and feature configuration |
|
To configure ARP MAD that uses management Ethernet ports:
Step | Command | Remarks | |
---|---|---|---|
1. Enter system view. | system-view | N/A | |
2. Assign a domain ID to the IRF fabric. | irf domain domain-id | By default, the domain ID of an IRF fabric is 0. | |
3. Configure the IRF bridge MAC address to change as soon as the address owner leaves. | undo irf mac-address persistent | By default, the IRF bridge MAC address remains unchanged for 6 minutes after the address owner leaves. | |
4. Enter management Ethernet interface view. | interface m-gigabitethernet interface-number | Of all management Ethernet ports on an IRF fabric, only the master's management Ethernet port is accessible. | |
5. Assign an IP address to the management Ethernet ports. | ip address ip-address { mask | mask-length } | By default, no IP addresses are configured. | |
6. Enable ARP MAD. | mad arp enable | By default, ARP MAD is disabled. |
