This next lab begins with a switch that has been configured to allow Telnet + SSH, including password protection – except the fact that neither switch yet has an IP address. This lab asks you to [...]
Today’s topic: A lot of administrative settings on a switch, particularly access passwords, that you need to set up when you first install a switch. Enjoy!
For this next lab, instead of just asking you what the IEEE auto-negotiation rules look like, the lab asks you to configure some switches in ways that affect auto-negotiation. But the lab gives [...]
Today’s post gives you another brief config lab exercise, this time with SSH. Like the previous lab post, this one starts with a cleanly-wiped router config (except the hostname) to make that one [...]
The CCNA certification includes many prominent features that need to be configured. VLANs. Trunking. Routing protocols. IPv4 addressing. IPv6 addressing. But there are also the occasional small [...]
One of the first configuration items that become second nature is the configuration of basic password settings. But it is also easy to forget about the small differences in password security [...]
A layer 2 switch does not need an IP address or default gateway for its primary purpose of forwarding layer 2 Ethernet frames. However, the switch does need an IP address and a default gateway [...]
Many of us start out learning about the simplest Cisco security option: One password for all users to reach user mode, with no per-user login. By today’s standards, that security method is [...]
The simplest way to protect the CLI uses passwords shared by all, rather than a per-user username and password. Using a per-user login method improves security. The easiest option for using [...]
Protecting access to the CLI of Cisco routers and switches starts with basic password security. From there, you can move on to use per-user login security that requires both a username and [...]
