The main advantage ofCisco Intersightis itscloud-based architecture, which allows IT administrators tomanage infrastructure from any locationwithout needing to install or maintain traditional on-premises management tools.

This provides:

Centralized visibility and control over UCS servers and HyperFlex infrastructure

Remote firmware upgrades and configuration

Policy-driven automation

Unlike on-premises tools, Intersight eliminates the overhead of maintaining dedicated infrastructure for management.

TheWireless LAN Controller (WLC)plays a central role in Cisco’s Unified Wireless Network solution by providing centralized management, configuration, and monitoring for multiple access points (APs). It allows for streamlined policy enforcement, seamless mobility, load balancing, and security management across wireless networks.

While WLCs facilitate wireless connectivity indirectly, their main role is tocentrally manage and controlaccess points — not to function as Layer 3 routers or format data frames.

When addressing call quality issues between IP phones, theReal-time Transport Protocol (RTP)is the primary protocol to analyze. RTP is responsible for the actual transmission of voice data during a call, and its performance directly impacts call quality.​

Key factors affecting RTP and, consequently, call quality include:​

Packet Loss:Missing packets can lead to audio gaps.

Jitter:Variations in packet arrival times can cause choppy audio.

Latency:Delays in packet delivery can result in noticeable lag.​

Analyzing RTP streams allows technicians to identify these issues and implement appropriate Quality of Service (QoS) measures to mitigate them.​

Incontrast:​

SIP (Session Initiation Protocol):Handles call setup, modification, and teardown but not the media stream.

SCCP (Skinny Client Control Protocol):A Cisco proprietary protocol for signaling, not media transport.

H.323:An older protocolsuite for multimedia communication, encompassing both signaling and media, but less commonly used in modern IP telephony.​Reference:Supporting Cisco Devices for Field Technicians (FLDTEC) – Troubleshooting Methodologie
