Asymmetric routing

Asymmetric routing is when a packet takes one path to the destination and takes another path when returning to the source. For example, review the following diagram. Packets from client to server take one route and packets from server to client take another route.

ROUTERA----->WAN LINK 1----->ROUTERB Going path.

ROUTERB----->WAN LINK 2 ----->ROUTERA Return path.

How to Upgrade Software on Cisco 5508/5520 HA WLC

The process to upgrade a Cisco Wireless Lan Controller is quite straightforward but there are a few things you need to be aware of which can minimise the downtime for your wireless network. This guide will go through the process to upgrade a pair of 5508 WLC’s configured in HA setup and connected back to back with RP port. Here is the Topology: Upgrade Software on Cisco 5508/5520 WLC – Steps The first step is to upload the new image to the controller. This process does nothing to your live network and only uploads the image to the controller. Download the image from cisco.com and store in a known location on your laptop. For the purpose of this guide I am using 8.0.121.0 .Don't forget to check compatible matrix for your AP Models. You will need a TFTP server running, I am using TFTPD32 running locally on my laptop. You can also use FTP or SFTP server to transfer the image. Copy the new image into your tftp directory and go to the GUI on your controller

How to upgrade software on a Cisco 3850 Switch | Recover Password | Configuration Backup | Restore Configuration

This short post will show you how to upgrade the software on a single Cisco 3850 switch or a 3850 stack, using TFTP and USB. The process is very easy but it is a bit different than the usual software image of previous switches i.e 3750 etc. The main difference is the Cisco 3850 switch run IOS-XE so you have to copy the .bin file to the flash on the switch and then install the software on the switch. Download the required image from cisco.com Begin the install Reboot the switch Step 1 copy the new image to the 3850 3850-SW1# copy tftp flash Address or name of remote host []? 10.1.1.100 Source filename []? cat3k_caa-universalk9.SPA.03.03.01.SE.150-1.EZ1.bin Destination filename [cat3k_caa-universalk9.SPA.03.03.01.SE.150-1.EZ1.bin]?

RSTP and MST Interview Questions and Answers[CCNP]

What are the Port Roles in RSTP? 1. Root port - It is the port on the switch that has the best root path cost to the root bridge. This is identical to 802.1D. 2. Designated port - The switch port on a network segment that has the best root path cost to the root. 3. Alternate port - A port that has an alternative path to the root, different from the path the root port takes. This path is less desirable than that of the root port. 4. Backup port - A port that provides a redundant (but less desirable) connection to a segment where another switch port already connects. If that common segment is lost, the switch might or might not have a path back to the root. What are different port states in RSTP? 1. Discarding - Incoming frames simply are dropped; no MAC addresses are learned.This state combines the 802.1D Disabled, Blocking, and Listening states. 2. Learning - Incoming frames are dropped, but MAC addresses are learned. 3. Forwarding - Incoming frames are forwa
