By | April 16th, 2013|Misc, Networking|

FTP or File Transfer Protocol is a program that you can use to transfer files between two machines on a network. In order to use FTP to transfer a file, both machines involved in the transfer must be attached to the network. To transfer a file you run the program ftp from one of the [...]

VLANs and Trunking and VLAN Configuration

By | April 12th, 2013|Misc, Networking|

A trunk is a link that carries traffic for more than one VLAN. Trunks multiplex traffic from multiple VLANs.  Two methods of identifying VLANs over trunk links are :  ■ Inter‐Switch Link (ISL): A Cisco proprietary method that encapsulates the original frame in a header, which contains VLAN information. It is protocol‐independent and can identify [...]

How to Configure, Verify and Troubleshoot a VLAN

By | April 12th, 2013|Misc, Networking|

Verifying VLAN Configuration  To see a list of all the VLANs and the ports assigned to them, use the command show vlan. To narrow down the information displayed, you can use these keywords after the command: brief, id, vlan‐number, or name  vlan‐name: ASW# show vlan brief  VLAN Name Status Ports  1 default active Fa0/1, Fa0/2, [...]

Virtual Local Area Network (VLAN) Basics

By | April 12th, 2013|Misc, Networking|

VLANs are used to break large campus networks into smaller pieces. The benefit of this is to minimize the amount of broadcast traffic on a logical segment.  VLAN  A virtual LAN (VLAN) is a logical LAN, or a logical subnet. It defines a broadcast domain. A physical subnet is a group of devices that shares [...]

Troubleshooting VLAN Trunk Protocol (VTP)

By | April 12th, 2013|Misc, Networking|

Troubleshooting VTP  The following are some common things to check when troubleshooting problems with VTP:  ■ Make sure you are trunking between the switches. VTP is sent only over trunk links.  ■ Make sure the domain name matches on both switches. (The name is case sensitive.)  ■ If the switch is not updating its database, [...]

Troubleshooting VLAN,Switch and Trunk Problems

By | April 12th, 2013|Misc, Networking|

Configuration problems can arise when user traffic must traverse several switches. The following sections list some common configuration errors. But before you begin troubleshooting, create a plan. Check the implementation plan for any changes recently made, and determine likely problem areas.  Troubleshooting User Connectivity  User connectivity can be affected by several things:  ■ Physical connectivity: [...]

Configuring EtherChannel

By | April 12th, 2013|Misc, Networking|

Basically, you should configure the logical interface and then put the physical interfaces into the channel group:  (config)# interface port‐channel number  For a Layer 3 EtherChannel, add the following: (config‐if)# no switchport (config‐if)# ip address address mask  Then, at each port that is part of the EtherChannel, use the following: (config)# interface { number | [...]

EtherChannel – Introduction

By | April 12th, 2013|Misc, Networking|

An EtherChannel is a way of combining several physical links between switches into one logical connection. Normally, Spanning Tree blocks redundant links; Ether Channels get around that and enable load balancing across those links. Traffic is balanced between the channel links on the basis of such things as source or destination MAC address or IP [...]

Adding a Cisco switch to a VTP domain

By | April 12th, 2013|Misc, Networking|

Adding a new switch in client mode does not prevent it from propagating its incorrect VLAN information. A server synchronizes to a client if the client has the higher configuration revision number. You must reset the revision number back to 0 on the new switch. To be safe, follow these steps:  1). With the switch [...]

Configuring VLAN Trunk Protocol (VTP)

By | April 12th, 2013|Misc, Networking|

Configuring VTP  VTP configuration is done at the global config mode. To configure the switch’s VTP mode:  (config)# vtp {server | client |transparent}  To configure the VTP domain name:  (config)# vtp domain name  To configure a VTP password (all switches in the domain must use the same password):  (config)# vtp password password  To configure the [...]
