snmp-server location
Congures the location of the SNMP server.
Syntax

Uplink Failure Detection
Uplink failure detection (UFD) indicates the loss of upstream connectivity to servers connected to the switch.
A switch provides upstream connectivity for devices, such as servers. If the switch loses upstream connectivity, the downstream devices
also lose connectivity. However, the downstream devices do not generally receive an indication that the upstream connectivity was lost
because connectivity to the switch is still operational. To solve this issue, use UFD.
UFD associates downstream interfaces with upstream interfaces. When upstream connectivity fails, the switch operationally disables its
downstream links. Failures on the upstream links allow downstream devices to recognize the loss of upstream connectivity. This allows the
downstream servers to select alternate paths, if available, to send trac to upstream devices.
UFD creates an association between upstream and downstream interfaces known as uplink-state group. An interface in an uplink-state
group can be a physical Ethernet or bre channel interface or a port-channel.
An enabled uplink-state group tracks the state of all assigned upstream interfaces. The failure of upstream interfaces results in automatic
disabling of downstream interfaces in the uplink-state group, as shown in the following illustration.
By default, if all the upstream interfaces in an uplink-state group go down, all the downstream interfaces in the same uplink-state group are
set into a link-down state.
