Cisco 3550 switches is a line of enterprise-class, stack-able, multi-layer switches that provide high availability, security and quality of service (QoS) to enhance the operation of the network. We have 12, 24 and 48 port models in stock and ready for immediate delivery.
As a network engineer, director of IT, or just setting up a lab to pass your certification test, we have certified Cisco engineers that understand your specific needs for your network environment. Call us today at 1-866-771-9785.
Why Choose Cisco 3550 Switches for my Network?
Cisco 3350 End of Life switches is no longer supported by Cisco. This means that they are not widely used for most new production or mission-critical deployments. While this may sound like a disadvantage, the fact is that this lack of support makes them a lot more affordable than the latest hardware.
If your organization has no need for the latest, bleeding-edge features, it is a waste of money to pay a premium for them. Instead, buy only the features you need and save money. Even if your environment is mission-critical or production, you can still use these switches in your environment without a lot of worries.
The fact that the Cisco Catalyst 3550 is end-of-life only means that Cisco does not offer support and updates for them. If you do need support for them, it can be purchased from a third-party. Another alternative is to purchase backup switches to have on hand in case there is an issue with the primary switches.
Failover network configurations are also possible with these switches, so that when your stack of switches can be configured to be completely redundant in order to handle network traffic even when one of the switches fails. If you are operating on a tight budget, you may be able to operate a network that is both highly affordable and able to be supported by your staff without any need for any third-party support. With the high redundancy that is possible when implementing a stack of these switches, traffic continues to flow even when one of the switches experiences a problem.
Key Features of Cisco Catalyst 3550 Switches
The Cisco 3550 supports many of the features that modern switches support. High-performance IP routing features such as CEF, or Cisco Express Forwarding, deliver good routing performance.
IP unicast routing protocols supported include RIPv1, RIPv2, OSPF, IGRP, EIGRP, BGPv4 to allow for routing, load balancing and scalable LANs. Inter-VLAN IP routing enables full Layer 3 routing between two or more VLANs. PIM, PIM-SM (sparse mode), PIM-DM (dense mode) and PMI sparse-dense mode are all supported. HSRP (Hot Standby Router Protocol) can be utilized to create a fully redundant routing topology. Equal-cost routing, DVMRP (Distance Vector Multicast Routing Protocol) and fallback bridging are also supported. The Cisco 3550 Catalyst supports redundancy in the form of Cisco UplinkFast/BackboneFast technology and CrossStack UplinkFast (CSUF) offers fast spanning-tree convergence through GigaStack GBICs. UDLD (Unidirectional Link Detection) and Aggressive UDLD can recognize incorrect fiber-optic wiring and port errors and automatically disable links. RSTP (Rapid Spanning Tree Protocol) and switch port Auto-recovery are also supported features of this switch.
This switch offers auto-sensing on non-GBIC ports and can negotiate speeds with attached network devices whether 10-, 100-, or 1000-Mbps. Dynamic Trunking Protocol (DTP) lets you enable trunking and Port Aggregation Protocol is supported to allow you to create Fast EtherChannel or Gigabit EtherChannel groups, which allow you to turn multiple links into one large pipe.
LACP (Link Aggregation Control Protocol) also provides similar capabilities. Cisco 3550 PoE would be a great feature, but unfortunately, 3550s were built on Cisco’s standards before power over Ethernet and only deliver 15 W of power on the port.
As you can see, Cisco Catalyst 3550 may be exactly what you need. It can provide the feature set that you need in a network, allow you to meet your budget by skipping those advanced cutting-edge features that you may not need.
Cisco Catalyst 3550 switches are still widely used in many companies and institutions—still running from when were installed in new deployments when these switches themselves were cutting edge. With a reliable track record, a robust and mature feature set and a more affordable price, Cisco 3550 switches can be a perfect fit for your network projects.
