Enhanced IGRP is an interior gateway routing protocol designed for various networks and media. Enhanced IGRP is an advanced distance-vector protocol. The underlying concepts are the same as those of distance-vector protocols, except that Enhanced IGRP is a non-periodic incremental protocol. This differs from traditional distance-vector protocols, in which complete routing updates are sent periodically, using unnecessary bandwidth and CPU resources. Improvements to Enhanced ..
To start the integration process for your identity systems, you first must understand the different forms identity can take in an organization. Some should be obvious to you; others you might not have considered. Physical Access Several mechanisms provide security for the physical access points to a facility. Lock and key • Magnetic card reader • Smart card All of these systems are capable of limiting access to a physical location..
Cisco Architecture for Voice, Video and Integrated Data (AVVID) also contains details on best practices for wireless networks. As wireless networks grow around the globe, Cisco intends to ensure that you can connect wherever you are, 24 hours a day, thereby boosting your connectivity to the workplace. This means, of course, that connectivity is required in areas where there are no cables, such as cafés, airplanes, street corners, and hotel lobbies. Wireless networks have be..
Sending Messages to Other Users
To send a text message to all active users logged into a router, use the send EXEC command. You must have administrator privileges to use this command: Router1#send * To send a private message to a user logged onto a specific line, use the send command with the line number: Router1#send 66 To send a private message to a user on the AUX port, use the following command: Router1#send aux 0 To send a private message to a user on the console port, use the following command: Router..
Some additional methods allow faster STP convergence if a link failure occurs: ■ PortFast—Enables fast connectivity to be established on access-layer switch ports to workstations that are booting ■ UplinkFast—Enables fast-uplink failover on an access-layer switch when dual uplinks are connected into the distribution layer ■ BackboneFast—Enables fast convergence in the network backbone or core layer switches after a spanning-tree topology change occurs Instea..
