Based on the provided reference, Cisco MRC, specifically referring to MRC cards, provides crucial upgrade capabilities for network optics and spans. These capabilities enable network operators to enhance system performance and capacity efficiently.
Key Functionalities of Cisco MRC Cards
According to the reference, MRC cards offer specific advantages in upgrading network infrastructure:
1. In-Service Upgrade from Single-Port Optics
- What it means: MRC cards allow you to upgrade from existing single-port optics cards without interrupting service.
- How it works: This upgrade utilizes the same service slot as the original single-port card, simplifying the process and avoiding the need to move hardware to different locations within the chassis.
- Benefit: Minimizes downtime and simplifies hardware management during upgrades.
2. Line-Rate Span Upgrades via SFP Module Replacement
- What it means: MRC cards support increasing the capacity or speed of a network link (span) to its maximum potential (line rate).
- How it works: This specific upgrade is achieved simply by upgrading the SFP module. The flexibility of changing the SFP allows for bandwidth adjustments or technology migrations on the existing MRC card.
- Benefit: Provides a flexible and cost-effective way to increase span capacity without replacing the entire card.
In summary, based on the reference, the core function described for Cisco MRC cards revolves around facilitating smooth and efficient network upgrades, both for optics types and span capacities, utilizing existing service slots and modular components like SFPs.
