TL-SL5428E 24-port 10/100Mbps + 4-port Gigabit L2 Managed Switch CLI Guide z history: Display the commands history. 1.3 Security Levels This switch's security is divided into two levels: User level and Admin level. User level only allows users to do some simple operations in User EXEC Mode; Admin level allows you to monitor, configure and manage the switch in Privileged EXEC Mode, Global Configuration Mode, Interface Configuration Mode and VLAN Configuration Mode. Users get the privilege to the User level once connecting console port with the switch or logging in by Telnet. However, Guest users are restricted to access the CLI.. Users can enter Privileged EXEC mode from User EXEC mode by using the enable command. In default case, no password is needed. In Global Configuration Mode, you can configure password for Admin level by enable password command. Once password is configured, you are required to enter it to access Privileged EXEC mode. 1.4 Conventions 1.4.1 Format Conventions The following conventions are used in this Guide: ¾ Items in square brackets [ ] are optional ¾ Items in braces { } are required ¾ Alternative items are grouped in braces and separated by vertical bars.
