ECMP (Equal-Cost Multi-Path) is a Layer 3 routing feature that allows traffic to be forwarded using multiple available paths of equal cost. This improves bandwidth utilization and provides redundancy. ECMP is commonly used in modern networks to optimize the flow of traffic and increase the resiliency of network connections.

Dell SONiC Management Interface Configuration:

In Dell SONiC, the management port configuration is a crucial aspect that allows administrators to access and manage the network device.

The management interface typically provides out-of-band management access to the device, ensuring that even if the data network is down, the management network can still be accessed.

Common Interface Naming Conventions:

mgmt 1/1/1: This naming convention is not typically used in Dell SONiC environments for management interfaces.

ma 0/1: This could be a potential naming convention but is not standard for Dell SONiC.

Management 0: This is a logical name but does not align with the standard interface naming conventions used in Dell SONiC.

eth0: This is the standard naming convention used for the primary management interface in most Linux-based systems, including Dell SONiC.

Verification with Dell SONiC Documentation:

Dell SONiC documentation specifies that the management interface is usually named eth0.

When accessing the management interface within the MF-CLI (Management Framework Command Line Interface) environment, eth0 is the correct interface to configure.

Practical Configuration Example:

When configuring the management port, the command might look something like:

config interface ip add eth0 /

This command specifies the management interface eth0 and assigns it an IP address for network management purposes.

This detailed step-by-step explanation confirms that the correct answer is D, providing insights into the typical interface naming conventions and configuration practices within the Dell SONiC environment.

The static route shown in the exhibit S* 12.0.0.0/16 via 192.168.45.254 Vlan45 is used to provide a route to the 12.0.0.0 network. This static route directs traffic destined for the 12.0.0.0/16 network through the gateway at 192.168.45.254, which is associated with VLAN 45. This configuration is typically used to ensure that traffic can reach a specific network via a defined path.

When RDMA over Converged Ethernet (RoCE) is enabled, Enhanced Transmission Selection (ETS) and Priority Flow Control (PFC) are two key elements that need to be configured. ETS allows for bandwidth allocation among different traffic classes, and PFC provides lossless Ethernet operation for specific traffic classes to support low-latency, high-performance network communication.

The show vlan command displays all configured VLANs on the device, including their status, ports, and other relevant details. It does not limit the display to only active VLANs or all possible VLANs but shows those that are currently configured.

Entering the qos-mode uniform command on a VTEP interface ensures that the DSCP (Differentiated Services Code Point) value of the payload is copied to the outer header DSCP value. This maintains the Quality of Service (QoS) markings across the VXLAN tunnel, allowing consistent traffic prioritization.
