Campus networks demand stability and scalability from their core. In this post, I explain how to use the Catalyst 5500 switch to meet these needs. This modular platform supports a wide range of interfaces and supervisory engines, which makes it ideal for growing enterprises.
I configure VLANs, deploy redundant supervisors, and optimize spanning tree settings to build a reliable Layer 2 backbone. By aggregating multiple Fast Ethernet or Gigabit Ethernet links, I ensure bandwidth meets user and application demands without compromising uptime.
The Catalyst 5500 plays a key role in campus design by serving as a distribution or core layer device. With modular slots, I adapt to evolving interface needs, such as FDDI or ATM, though Fast/Gig uplinks dominate most environments. I maintain configuration backups and document slot assignments for fast recovery and simplified audits.
High availability comes from redundant power supplies and supervisor failover. This allows the switch to recover quickly from hardware issues. I monitor CPU load, interface counters, and backplane utilization to catch performance issues early and stay ahead of demand.
For those new to modular switch design, the 5500 offers a balance of simplicity and power—especially when paired with sound configuration and cabling practices.
