Question 176

-- Exhibit

-- Exhibit --

Refer to the exhibit.

Based on the output of the tmsh interface show command, what is the issue?

There is a duplex mismatch on the management interface.

Interfaces 2.1 and 2.2 are defective and need replacement.

Flow Control is NOT configured on the management interface.

There are too many drops on inbound traffic on interface 1.1.

Correct Answer: A

The issue in the exhibit is a duplex mismatch on the management interface. Duplex mismatch occurs when one end of the connection is configured for full duplex while the other end is set to half duplex. This can lead to packet loss, collisions, and overall degraded performance, which is evident from the presence of errors in the management interface column. The management interface in the exhibit shows it is operating in 100TX-HD mode, indicating it is set to half duplex, which is likely causing the mismatch. This is a common issue affecting connectivity and performance.

Discussion

GVKDOption: A

A - Correct Interface configurations like speed or duplex mismatch can be a failure due to auto-negotiate not working correctly or a mistake in manual configuration on interfaces at either end of the connection. This may result in a loss of packets in higher volume networks, collisions and or duplex errors. PS. Flow Control is not available on the Management interface. https://clouddocs.f5.com/training/community/f5cert/html/class1/modules/module2.html#:~:text=Interface%20configurations%20like%20speed%20or,collisions%20and%20or%20duplex%20errors.
