Catalyst 3750 Switch Software Configuration Guide 12.2(55)



I'm configuring a model WS-C3750X-24 running software version 12.2(55)SE5 for scp access in order to back up and update its configuration from a Linux administration server. The necessary commands such as "ip scp server enable" and "aaa authorization exec" are mentioned in forum postings and do work, but I cannot find them in the actual documentation, specifically the Command Reference and Configuration Guide.




Catalyst 3750 switch software configuration guide 12.2(55)



The new Cisco 3750 switch series is undoubtedly an innovative line, featuring Gigabit and Fast Ethernet switches all with Cisco StackWise technology, which helps develop a large highly resilient and unified switching system by incorporating a single switch at a time. To start with it uses 32-GBps interconnect with StackWise technology on a fixed stackable configuration that provides intelligent services using IPv6 and dynamic IP routing on Layer 2 to Layer 4 switching. Then there is the 10 Gigabit Ethernet, Gigabit Ethernet and Fast Ethernet connectivity capability plus 4 SFP ports and a maximum of 48 10/100/1000 ports with PoE.


As mentioned above, the Cisco Catalyst 3750 (V2 / Version 2) series is considered a next-gen Layer 3 Fast Ethernet energy efficient stackable switch solution. With the Energy Wise technology from Cisco, these switches help reduce power consumption of any network and therefore decrease the carbon footprint and energy costs. Basically, the 3750 series uses much less power compared to all the previous Cisco Catalyst switches making it great for retail, enterprise and branch based environments where productivity counts. Moreover, this series is popular as it comes with two software images.


These are all new features never before seen on any Cisco switch. Some other hot features to look out for in the Catalyst 3750 series are QoS increased availability, IOS software version check and auto update with automatic configuration, which leads to faster deployment and less down time. With the hot delete and add option, you can now increase or decrease the number of switches while keeping the stack running.


Cisco 3750 GUI / Web interface: Cisco reports the easiest way to manage the switch is by using the device manager that is in the switch memory. Device Manager can be accessed from anywhere in the network through a web browser. Do the following: 1. Launch a web browser on your PC or workstation. 2. Enter the switch IP address in the web browser, and press Enter. The device manager page appears. 3. Use the device manager to perform basic switch configuration and monitoring. Refer to the device manager online help for more information. 4. For more advanced configuration, download and run the Cisco Network Assistant, which is described in the next section. Also, the Cisco Network Assistant (CNA) is a PC-based network management application that manages standalone devices and clusters of devices from anywhere in your intranet.

Cisco 3750 vs Juniper EX4200 Switches: How it compares: A comparable model to the Cisco Catalyst 3750 Series Switches, the Juniper EX4200 line is available with or without Power over Ethernet (PoE) and is sold in 24 and 48-port 10/100/1000 configurations. The EX 4200 offers modular uplink connectivity of 1GB or 10GB. The Juniper 4200 switches have a minor leg up on most 3750 models by offering hot swap power supplies, rather than a fixed power supply which is non-field-serviceable.


Can you help with the following defaults for a 3750? * 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 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 ' with the specific password. However, the Cisco Catalyst 3750-X and 3560-X Getting Started Guide reports, Start a browser session on the PC, and enter the IP address 10.0.0.1. When prompted, enter the default password, cisco. Note The switch ignores text in the username field. For default IP Address, the Cisco 3750-X and 3650-X Getting Started Guide reports no IP address or subnet mask are defined. See: _3560x/software/release/12.2_55_se/configuration/guide/swipaddr.html.


How to do a factory reset of a Cisco 3750: Resetting the Switch This section describes how to reset the switch by rerunning Express Setup. These are reasons why you might want to reset the switch: You installed the switch in your network and cannot connect to it because you assigned the incorrect IP address. You want to clear all configuration from the switch and assign a new IP address. You are trying to enter Express Setup mode, and the switch LEDs start blinking when you press the Mode button (which means that the switch is already configured with IP information). ***Resetting the switch deletes the configuration and reboots the switch. To reset the switch: Press and hold the Mode button. The switch LEDs begin blinking after about 3 seconds. Continue holding down the Mode button. The LEDs stop blinking after 7 more seconds, and then the switch reboots. The switch now behaves like an unconfigured switch. You can enter the switch IP information by using Express Setup as described in the "Running Express Setup" section.


How to erase a config on a Cisco 3750? See the Cisco page called Resetting Catalyst Switches to Factory Defaults at _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.


As with the stacking of 2960S or 3750, network professionals do not need to configure the switches. The stacking is done automatically by the switch by connecting the FlexStack or StackWise cables. However, there will be some work for the network professional to get the mixed stack configuration working properly.


In this scenario, the existing stack is 2960S with 12.2 IOS image and 2960X with 15.0 IOS image. As with the stacking of 2960S and 3750, the IOS needs to match first before the switch can join the stack properly. That said, the 2960S needs to be upgraded to the same software train as the 2960X.


Please i have a slight challenge i have been trying to figure out how two switches will work connecting to a fibre optic transmitter cable specifically two 3750 switches and the also the configuration to make them communicate.kindly assist .Thanks a million 2ff7e9595c
