Which statement is true for a device with a MAC address of B8-31-B5-80-41-4F?
A MAC address is divided into two parts: the Organizationally Unique Identifier (OUI) and the Network Interface Controller (NIC) serial number. The OUI is the first three octets of the MAC address and is unique to the manufacturer. The NIC serial number is the last three octets and is unique to the device itself. Therefore, for the MAC address B8-31-B5-80-41-4F, the OUI is B8-31-B5, and the NIC serial number is 80-41-4F.
What is used by network devices to send error and operational information related to IP communications?
ICMP (Internet Control Message Protocol) is used by network devices to send error and operational information related to IP communications. It is used to send messages like 'destination unreachable' or 'time exceeded' when there are issues in IP communication
You have physical access to an Aruba CX-Switch with unknown/lost credentials. What are the possible steps to rebuild the credentials? (Select two.)
To regain access to an Aruba CX switch when credentials are unknown or lost, one can press and hold the clear button, then power cycle the switch to reset the password. Additionally, using the boot profile 0 at the boot loader menu can be used to bypass the current startup configuration, which may include the unknown credentials.
What is indicated by a flashing amber global status indicator LED on an Aruba CX6200M?
A flashing amber global status indicator LED on an Aruba CX6200M switch typically indicates that the switch has encountered a fault, but it is recoverable. This LED behavior serves as an alert to the network administrator that an issue needs to be addressed, but it does not necessarily mean that the switch is inoperable.
You are working with a pair of 6300M switches in a VSF stack. The switch has 48 SmartRate 5G ports, 2 SFP28 ports, and 2 SFP56 ports. Both SFP56 ports are used for stacking.
You need to provide an LACP connection to another identical stack with the maximum available bandwidth possible. What should you configure?
To provide an LACP connection with the maximum available bandwidth, one should configure a link aggregation group (LAG) using all available ports that can be used for data transfer. Since the SFP56 ports are used for stacking, the next best option is to use the 2 SFP28 ports and as many SmartRate 5G (SR5) ports as possible on each switch, which would allow for a 16-member LAG, with 2 SFP28 and 6 SR5 ports on each switch contributing to the LAG.
