Working on our practical networking lessons our students and I, as their teacher, we are usually configuring several routers and switches (sometimes up to ten), which are accessible remotely. For this, we welcome the use of multi-tabbed and especially multi execution clients.
They allow us to eficiently organize working space and run commands in one task on all connected network equipments (for example to save running config).
My students received the message “You did not complete all requirements” even though they are set to “Pass”.
It is an Netacad issue. The instructor can resolve this by manually refreshing the Course Details in the following way:
In this article I will configure, debug and shows the process of RIPv2 authentication.
This example shows how to generate 254 loop interfaces with assigned ipv4 addresses 172.16.0.1/24 up to 172.16.255.1/24. The code is:
enable
tclsh
for {set i 0} {$i < 256} {incr i} {
ios_config "int loop $i" "ip address 172.16.$i.1 255.255.255.0"
}
ios_config "end"
tclquitand you may just simply copy and paste it into a Cisco router CLI. Therefore first run tclsh within of privileged EXEC mode
In this article I will configure dynamic complex ACL (Lock and Key). This technique is described during CCNA4 Exploration.
Description from the cisco web
Once if we are allowed download zipped version of ccna curriculum (for example as an netacad instructor) we should be able run them locally without web server need. However there is a problem to display these curriculums by default as it contain embeded flash animation. This problem persists in different browsers (firefox, chrome, epiphany) for example.
The default configuration for the switch allows an end user with physical access to the switch to recover from a lost password by interrupting the boot process during power-on and by entering a new password. These recovery procedures require that you have physical access to the switch.
Working with my HP Terminal server, which we are using as a remote console acccess solution allows us login into Cisco router console ports remotely, i'm loosing the Putty connection due to inactivity. However the PuTTY client can be configured to maintain a connection and not time it out. All what we need to do is setup built-in keepalive machanism:
A simple comparison of the nslookup command, the Microsoft DNS tool, and dig, the linux/win based command alternative.
