Cisco 3550 Switch Overview: As a stackable multilayer switch, the Cisco 3550 Switch series offers a good QoS (Quality of Service), high availability and greater security for higher network operations. It also features a whole host of Gigabit and Fast Ethernet configurations making it a perfect option for metro access and enterprise applications. As always, it comes with plenty of industry leading intelligent services and the Cisco Network Assistant to administer the switches.
Considered as an enterprise class of switches, the Cisco 3550 is a series of multilayer and stackable switches with intelligent Ethernet capabilities that enhances operation of the network using QoS, high availability and ease of access to administrators. Not only is it a power access layer switch for medium sized enterprise level wiring closets but also can form the backbone for small networks. What does make the 3550 series famous is its industry leading intelligenet services such as high performance IP routing, traditional LAN switching simplicity, QoS rate limiting, multicast management and Cisco security access control lists. Moreover, with the Cisco Network Assistant's GUI interface, it is easy to troubleshoot, configure and monitor the network while managing a whole host of administrative tasks with wireless access points, routers and switches.
The foremost feature of the Catalyst 3550 switch series is the CMS or Cisco Cluster Management software that lets you handle multiple Catalyst desktop switches at once using a web browser interface. Now with new configuration wizards, it is easier to implement intelligent services and create a converged network. Take for example, the 3500-24 PWR switch that helps drastically reduce cost of ownership when incorporating Cisco IP phones or even the Aironet wireless LAN Cisco access points. By delivering a decent 15 Watts of inline power integrated on each and every 10/100/1000 port, it eliminates the need to find access to wall power for any WLAN or IP Phone. Moreover, the cost of laying down new cables also comes down as you really don't need cables to now power such deployments. By combining the 3550 switches with Cisco Redundant Power System 675, you can ensure against power failures and protect against loss of power using a UPS system. The Cisco Catalyst 3550 Series of Intelligent Ethernet Switches come in the following setups. WS-C3550-
The following models incorporate a large range of GBIC transceivers “ the 1000BASE-T, 1000BASE-LX/LH, CWDM GBICS, 1000BASE-ZX, 1000BASE-SX. With such a dual Gigabit Ethernet setup using Fast Ethernet configurations, customers can manage to deploy tremendous flexibility and implement uplink and stacking configuration immediately while retaining the ability to later on migrate the same exact configuration to any another location or system. Similarly, the Catalyst 3550 switches offer dual redundant GBIC uplinks with a loopback cable, CrossStack, Uplink Fast technologies that helps in retaining higher levels of stack resiliency. Now never face stack interconnection failure and always retain the high speed uplink on a second-by-second basis. It also offers PVST+ for uplink load balancing. With the Gigabit Ethernet flexibility, the 3550 Catalyst series becomes the perfect LAN edge partner to the 6500 family of Catalyst Gigabit Ethernet LAN core optimized switches. A point to note, the SMI or Standard Multilayer Softare Image is available with only the Catalyst 3550-24, 3550-24-FX, 3550-48, 3550-24-DC and 3550-24-PWR. On the other hand Enhanced Multilayer Image or EMI is available with all the models in the 3550 switch series. The difference between the two lies in the capabilities. While SMI offers rate limiting, QoS, ACLs, routed information protocol functionality and basic static, EMI provides a vastly superior range of enterprise level features such as multicast, advanced hardware IP unicast, WCCP or Web Cache Communication Protocol and more. With the above mentioned switches one can upgrade to the EMI using the EMI upgrade kit. However, the 3550-12G and 3550-12T models both come with EMI built into it.

Can you help with the following defaults for a 3550? * Default username: * Default password: * Default IP Address: For default username/password, a member on the Cisco Support Community reports: This is no default username/password included in a switch. You will need to enter the following command. username <username> password <password> Obviously remove the <> in username and password. If you don't set this, the only other way you can connect is via telnet, console, and or ssh. Under line vty you need to enter 'login' and then 'password <password>' with the specific password. The following table details default switch information for the Cisco Catalyst 3550:
For default IP Address, No IP address or subnet mask are defined as a default setting for Cisco Catalyst 3550 switches. See http://www.cisco.com/en/US/docs/switches/lan/catalyst3550/software/release/12.2_25_see/configuration/guide/swipaddr.html for more information.

How to do a factory reset of a Cisco 3550: To reset the Cisco Catalyst 3550 to factory defaults, see the Cisco document entitled Resetting Catalyst Switches to Factory Defaults at http://www.cisco.com/en/US/products/hw/switches/ps607/products_tech_note09186a00800c4546.shtml
What is the Boot System Command for a Cisco 3550? If you use a CMS image on the 3550, the Cisco IOS image (.bin file) extraction creates a directory for the image alone. The boot system command becomes boot system flash: directory/file_name. See the Cisco page for Upgrading Software Images on Catalyst 3550 Series Switches Using Command Line Interface at: http://www.cisco.com/en/US/products/hw/switches/ps646/products_configuration_example09186a0080169623.shtml
How would you do a Break Sequence for a Cisco 3550? What break sequence to use depends upon the terminal application and operating system you are using. HyperTerminal that runs on Windows 2000 uses Ctrl-Break. See Cisco's page on Recovering Catalyst Fixed Configuration Switches from a Corrupted or Missing Image at http://www.cisco.com/en/US/products/hw/switches/ps628/products_tech_note09186a0080169696.shtml for more information.
How to erase a config on a Cisco 3550? See the Cisco page called Resetting Catalyst Switches to Factory Defaults at http://www.cisco.com/en/US/products/hw/switches/ps607/products_tech_note09186a00800c4546.shtml Cisco notes that you will need access to the switch console through either a physical console or a Telnet connection and will also need the console/enable passwords. If you have forgotten the console and enable password of the switch, you cannot reset the configuration to factory default to reset the password. In this situation, follow password recovery procedures for your switch.
How to set the time zone on a Cisco 3550? Beginning in privileged EXEC mode, follow these steps to manually configure the time zone:
The minutes-offset variable in the clock timezone global configuration command is available for those cases where a local time zone is a percentage of an hour different from UTC To set the time to UTC, use the no clock timezone global configuration command.
How do you execute a boot system command on a 3550? See Cisco's page entitled Catalyst 3550 Switch Bootloader Commands at http://www.cisco.com/en/US/docs/switches/lan/catalyst3550/software/release/12.2_44_se/command/reference/bootldr.html. If you use a CMS image on the 3550, the Cisco IOS image (.bin file) extraction creates a directory for the image alone. The boot system command becomes boot system flash: directory/file_name.
