Active Path Failover Configuration: Directed Arp - HP Integrity rx2800 - i2 White Paper

Figure 4-5 Active Path failover configuration: Directed ARP
Community Address ARP Configuration:
To enable Active Path's Community Address ARP mechanism, select Community Address
ARP from the Echo Node Response Mechanism drop-down box. In addition to supplying the
Echo Node IP address, it is necessary to supply a Community Probe IP Address.
Community Address ARP guidelines:
• Use the same Echo Node, Community Probe IP, and Community Probe MAC address for
as many servers as possible on the same subnet. This allows a single Echo Node reply from
the Echo Node to validate connectivity for all teamed ports on the network.
• Ensure the Community Probe IP address and Community Probe MAC address are not used
by any other device in the network (other than another team for Community Address ARP).
• Ensure the Community Probe IP address and Community Probe MAC address are not used
as the team's IP address and/or MAC address.
• If DHCP is in use, the IP address for the Community Probe IP address may need to be
excluded from the DHCP scope on the DHCP server.
