EtherChannel is a technology that allows you to bundle multiple physical links into a single logical link between two network devices, such as switches or routers. This can provide benefits such as increased bandwidth, improved redundancy, and load balancing.
When setting up an EtherChannel, you need to choose a protocol to use for negotiating and managing the channel. The two standard protocols for this are Link Aggregation Control Protocol (LACP) and Port Aggregation Protocol (PAgP).
Of the options listed, A. LACP is the correct answer for the standard industrialized protocol of EtherChannel. LACP is defined in IEEE 802.3ad and is widely supported by most major network vendors. It provides a standardized method for negotiating and managing EtherChannels and is often the preferred protocol for larger networks due to its scalability and ease of configuration.
B. PAgP is also a protocol for EtherChannel negotiation and management, but it is a Cisco proprietary protocol and is not as widely supported as LACP. PAgP can only be used between Cisco devices, whereas LACP can be used between devices from different vendors.
C. PRP (Parallel Redundancy Protocol) and D. REP (Resilient Ethernet Protocol) are both protocols used for redundant networking, but they are not specific to EtherChannel. PRP is a protocol that allows for parallel paths in a network to be active and provide redundancy, while REP is a protocol that allows for fast recovery from network failures by creating backup paths.
In summary, the standard industrialized protocol of EtherChannel is LACP, which provides a standardized and widely supported method for negotiating and managing EtherChannels.
