Understanding Link Aggregation:
Definition: Link aggregation combines multiple network connections into a single logical link to increase bandwidth and provide redundancy.
Usage in High-Bandwidth Scenarios:
Combining Links: By aggregating multiple 1Gbps connections, the facility can utilize the full 2.5Gbps bandwidth provided by the ISP.
Benefits: Enhanced throughput, load balancing, and redundancy, ensuring better utilization of available bandwidth.
Comparison with Other Options:
802.1Q Tagging: Used for VLAN tagging, which does not affect the physical bandwidth utilization.
Network Address Translation (NAT): Used for IP address translation, not related to link speed or bandwidth aggregation.
Port Duplex: Refers to the mode of communication (full or half duplex) on a port, not the aggregation of bandwidth.
Implementation:
Configure link aggregation (often referred to as LACP - Link Aggregation Control Protocol) on network devices to combine multiple physical links into one logical link.
