The command "tc qdisc del dev ${eth0}" is used to delete a network queuing discipline (qdisc) from a specific network device (${eth0}).
Here is a breakdown of the command:
-
"tc" stands for "traffic control." It is a command-line utility in Linux used to configure and manage network traffic control settings.
-
"qdisc" refers to a queuing discipline. In Linux, a qdisc is used to control the flow of network packets by applying various algorithms and policies.
-
"del" is short for "delete." It is the action we want to perform on the qdisc.
-
"dev" specifies the network device on which the qdisc is configured. In this case, "${eth0}" is a placeholder for the Ethernet network interface (e.g., eth0, eth1).
Therefore, the command instructs the system to remove a queuing discipline from the specified network device.
