upgrades. To reload the switch in the last configured mode: Normal reload or BMP
mode, you can enter the reload command at any time.
Upgrade any configuration changes that have changed the NVRAM content by
performing a reload on the chassis.
While BMP is on, the Dell Networking OS Command Line Reference Guide prompt
changes to "Dell-BMP".
Uplink Failure Detection (UFD)
Uplink failure detection (UFD) provides detection of the loss of upstream connectivity and, if you use this
with network interface controller (NIC) teaming, automatic recovery from a failed link.
NOTE: In Standalone, VLT, and Stacking modes, the UFD group number is 1 by default and cannot
be changed.
clear ufd-disable
Re-enable one or more downstream interfaces on the switch/router that are in a UFD-Disabled Error
state so that an interface can send and receive traffic.
Syntax
clear ufd-disable {interface interface | uplink-state-group
group-id}
Parameters
interface
interface
uplink-state-
group group-id
Defaults
A downstream interface in a UFD-disabled uplink-state group is also disabled and is
in a UFD-Disabled Error state.

Specify one or more downstream interfaces. For interface,
enter one of the following interface types:
•
Fast Ethernet: fastethernet {slot/port | slot/
port-range}
•
1 Gigabit Ethernet: gigabitethernet {slot/port |
slot/ port-range}
•
10 Gigabit Ethernet: tengigabitethernet {slot/
port |slot/ port-range}
•
Port channel: port-channel {1-512 | port-
channel-range}
Where port-range and port-channel-range specify a
range of ports separated by a dash (-) and/or individual
ports/port channels in any order; for example:
gigabitethernet 1/1-2,5,9,11-12 port-channel
1-3,5. A comma is required to separate each port and port-
range entry.
Re-enables all UFD-disabled downstream interfaces in the
group. The valid group-id values are from 1 to 16.
