    Core Switch Multicast Anomaly

    On the wired side, Port Anomaly introduces a proactive metric for identifying potential trouble before it escalates. By monitoring port flapping, loops, and related issues, admins receive early notifications through Alarm Manager, helping maintain a stable backbone. It's a long story but I'll keep it short. The network is as below: Third Floor (core switch) ISP Internet Router (GATEWAY DEVICE for all 30 vlans) Stack 1 : 5 x. Essentially, all of the AV equipment sits on a stack of MS225 switches which are connected via Port-Channel to a Meraki managed Catalyst 9300 core switch. When we connect the devices directly to the source VLAN, everything works fine; however, we cannot receive the multicast service on other VLANs. The IPTV Multicast service is provided. Maybe someone have a good multicast experience with DELL, juniper, HP, arista, Extreme, Nokia? From hardware standpoint, i need a pair of switches, with at least 8 ports 10G sfp+, and 24 ports 1G each. ipforwarding and ipmcfowarding is enabled on X670 for both VLANs.

  • Is a core switch required

    Is a core switch required

    For networks with more than 100 computers, a core switch is required for stable and high-speed operation. A core switch is a high-capacity, high-performance Layer 3 switch positioned at the physical backbone of an enterprise network. Engineered to aggregate massive volumes of data from distribution switches, it provides ultra-low latency and maximum throughput to ensure uninterrupted routing and packet. The core switch is the most important piece of hardware in this infrastructure, acting as the high-speed, central nervous system that ensures all parts of the network can communicate. The primary transmission and routing of data signals take place at the core layer only. Simply put, it's the kingpin that keeps your network humming. It's designed to handle significant amounts of traffic with advanced features like redundancy and scalability.

    Packet loss when routing to the core switch

    Use the following commands (based on switch OS): 2. Verify Port Configuration Ensure both sides of a link have the same speed/duplex settings. Recently, we encountered a case involving a Cisco C9500 core switch experiencing high latency affecting internal servers communicating with external destinations. The initial symptoms pointed towards a classic network bottleneck, but the root cause turned out to be a less obvious configuration. Our room controllers operate on a loop topology just daisy chaining one device to another to another etc, until it reaches EOL, and then the last device loops back to the floor switch creating a loop that is protected by the RSTP. This is just to have that small amount of redundancy in case 1. I manage a Wide Area Network with 50 + subnets all connected through Intern Vlan Routing via Layer 3 switched virtual Interfaces ( SVI) on a Core 6800 L3 switch.
