C
Command Alias A shortcut for commonly-used commands.
Configuration
mode
A mode that enables you to change the current running configuration.
Control-plane
policing
A Quality of Service (QoS) mechanism that increases system security by protecting the route processor
from unnecessary traffic and prioritizing important control plane and management traffic.
Converged
Enhanced
Ethernet (CEE)
A technology that uses DCBX specification v1.01 to enable interoperation with a larger set of switches
when using Data Center Bridging (DCB).
Curl command A Linux shell command that generates HTTPS requests executed on an external server.
D
Data Center
Bridging
Exchange
(DCBX)
A protocol that allows a switch to automatically discover and set up DCBX-enabled peers that are
configured with compatible settings. In a converged data center network, DCBX provides plug-and-play
capability for server, storage, and networking devices in an end-to-end solution.
Default VLAN A VLAN instance to which ports are assigned when they are not being used. Ports that are
administratively up in the L2 mode are automatically placed in the default VLAN as untagged interfaces.
On SmartFabric OS10 switches, VLAN 1 is the default VLAN.
Dell Digital
Locker
A service associated with your Dell Technologies user account that enables you to download purchased
software, access licensed software products, download updates and patches, manage user and product
groups, view software license entitlements, and manage warranty subscriptions.
Dell EMC
SmartFabric
OS10
A network operating system that supports multiple architectures and environments.
Destination
group
An arrangement that identifies the IP address and transport port on a destination server to which
telemetry data is streamed.
DHCP relay agent A process that relays DHCP messages to and from a remote DHCP server, even if the client and server
are on different IP networks.
DHCP server A server that provides network configuration parameters to DHCP clients on request. A DHCP server
dynamically allocates four required IP parameters to each computer on the virtual local area network
(VLAN) — the IP address, network mask, default gateway, and name server address. DHCP IP address
allocation works on a client/server model where the server assigns the client reusable IP information from
an address pool.
DHCP snooping A Layer 2 (L2) security feature that helps networking devices to monitor DHCP messages and block
untrusted or rogue DHCP servers.
Dial-out mode A mode where the switch initiates a session with one or more devices according to the sensor paths and
destinations in a subscription.
Differentiated
Services Code
Point (DSCP)
A network layer service that classifies and manages network traffic and provides Quality of Service (QoS)
to modern IP networks.
DNS A protocol that is responsible for name server registration and management of Nx_Ports that are
attached to the switch.
Docker-CE A free containerization platform that allows you to download and install external packages and run them
within OS10.
Duplicate
Address
Discovery (DAD)
A protocol that verifies the uniqueness of IPv6 home address on the LAN before the address is assigned
to a physical interface.
