Reflection You may have noticed that some of the practices used to configure the network devices are out-of-date, inefficient, or not secure. Make a list of as many recommendations that you have regarding how the devices should be reconfigured to follow the practices that you have learned in the CCNA curriculum. 1. Change telnet to SSH for security reason. 2. Don’t use vlan1 as a management vlan, change to other number, management should be on a controlled vlan. 3. shutdown the unused ports. 4. enable port-security 5.don't propagate ospf to end device ports by using passive interface 6. use ACLs for security for the PC with sensitive information like on acct vlan and admin vlan 7. implement 802.1x 8.Limit CDP usage, CDP is on by default, should be turned off, only turned on when need use. 9. Disable DTP(dynamic trunking protocol)
