DescriptionName
This option determines whether Cisco Discovery Protocol (CDP) is
enabled on servers associated with a service profile that includes this
policy. This can be one of the following:
• Disabled
• Enabled
CDP field
Whether adapter-registered MAC addresses are added only to the native
VLAN associated with the interface or added to all VLANs associated
with the interface. This can be one of the following:
• Only Native Vlan—MAC addresses are only added to the native
VLAN. This option is the default, and it maximizes the
port+VLAN count.
• All Host Vlans—MAC addresses are added to all VLANs with
which they are associated. Select this option if your VLANs are
configured to use trunking but are not running in Promiscuous
mode.
MAC Register Mode field
This option determines how the VIF behaves if no uplink port is
available when the fabric interconnect is in end-host mode. This can be
one of the following:
• Link Down— Changes the operational state of a vNIC to down
when uplink connectivity is lost on the fabric interconnect, and
enables fabric failover for vNICs.
• Warning— Maintains server-to-server connectivity even when
no uplink port is available, and disables fabric failover when uplink
connectivity is lost on the fabric interconnect.
The default is Link Down.
Cisco UCS Manager, release 1.4(2) and earlier did not enforce
the Action on Uplink Fail property for those types of
non-VM-FEX capable converged network adapters mentioned
above. If the Action on Uplink Fail property was set to
link-down, Cisco UCS Manager would ignore this setting and
instead issue a warning. In the current version of Cisco UCS
Manager this setting is enforced. Therefore, if your
implementation includes one of those converged network
adapters and the adapter is expected to handle both Ethernet
and FCoE traffic, we recommend that you configure the Action
on Uplink Fail property with a value of warning.
Please note that this configuration may result in an Ethernet
teaming driver not being able to detect a link failure when the
border port goes down.
