How to aggregate two core switches

Fiber optic patch cord knowledge brief Published 22 Mar 2023

Prepared for preliminary research by the JEWELBLU OPTICAL knowledge desk. Confirm connector types, fiber grades, polish, loss budgets and installation requirements against current standards and product documentation.

To establish a VSX relationship between the core switches, create a link aggregation (LAG) interface for assignment as the VSX data plane's inter-switch link (ISL). The LAG can be defined at the Central UI group level when using the same ports for the VSX ISL on both core switches. I'd like to know, is it possible to uplink a fiber link from the WS-C2960G-48TC-L to each of the core switches. By bundling multiple network connections into a single high-bandwidth link, aggregation switches help. Link Aggregation is a nebulous term used to describe various implementations and underlying technologies.

How to aggregate two core switches
Can I aggregate multiple uplink ports between Ethernet switches?

Can I simply connect 4 of the 40-GbE uplinks between the two switches and get ~160 Gbps of bandwidth between the two rooms? No. Running multiple connections between switches causes
