The primary blade in a clustered system may send management traffic sourced from the blade IP address associated with the management port instead of from the cluster IP address. In addition, traffic sourced from the management interface of a VCMP guest may fail with an ICMP 'destination unreachable' message.
Services that receive traffic from the management interface of the primary blade in a physical cluster may not recognize the cluster as the source of the traffic. Services that depend on traffic sourced from the management interface of a VCMP guest may fail.
On a physical cluster, functionality that generates traffic over the management interface of the primary blade (such as RADIUS authentication, remote logging, ping) result in traffic sourced from the IP address of the primary blade, not the cluster floating IP address. On a VCMP guest, functionality that generates traffic over the management interface of the guest may fail with an ICMP 'destination unreachable' message.
None.
The primary blade in a clustered system now sends management traffic sourced from the cluster IP address. In addition, traffic sourced from the management interface of a VCMP guest no longer fails with an ICMP 'destination unreachable' message.
