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
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.

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.

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.
