Presentation Transcript

  1. CCNA 3 v3.0 Module 6 Switch Configuration

  2. Objectives • Starting the switch • Configuring the switch

  3. Physical Startup of Catalyst Switches • Switches typically have no power switch to turn them on and off. • They simply connect or disconnect from a power source.

  4. Switch LED Indicators

  5. Verifying Port LEDs During Switch POST

  6. Connecting a Switch to a PC

  7. Examining Help in the Switch CLI

  8. Show Commands in User EXEC Mode

  9. Verifying the Catalyst Switch Default Configuration • show running-config • show interface • show vlan • show flash • show version

  10. Configuring the Catalyst Switch • To overwrite any existing configuration, follow these steps: • Remove any existing VLAN information by deleting the VLAN database file, vlan.dat from the Flash memory directory. • Erase the backup configuration file startup-config. • Reload the switch.

  11. Web Management Interface Configuring the Catalyst Switch

  12. Managing the MAC Address Table Switches learn the MAC addresses of PCs or workstations that are connected to their switch ports by examining the source address of frames that are received on that port.

  13. Configuring Static MAC Addresses • A MAC address can be permanently assigned to an interface. The following are reasons to assign a permanent MAC address to an interface: • - The MAC address will not be aged out automatically by the switch. • - A specific server or user workstation must be attached to the port and the MAC address is known. • - Security is enhanced.

  14. Configuring Port Security

  15. Executing Adds, Moves, and Changes

  16. Managing Switch Operation • An administrator should document and maintain the operational configuration files for networking devices. • The most recent running-configuration file should be backed up on a server or disk. • The Cisco IOS Software should also be backed up to a local server. The Cisco IOS Software can then be reloaded to Flash memory if needed.

  17. Passwords • For security and management purposes, passwords must be set on the console and vty lines. • An enable password and an enable secret password must also be set.

  18. Firmware and IOS Images • IOS and firmware images are periodically released with bugs fixed, new features introduced, and performance improved. • If the network can be made more secure, or can operate more efficiently with a new version of the IOS, then the IOS should be upgraded • To upgrade the IOS, download a copy of the new image to a local server from the Cisco Connection Online (CCO) Software Center.
