Maipu Basics

Here I am covering some basics of Maipu Router, which everybody need in daily routine while monitoring Maipu routers.

Topics Covered –

CPU , Memory, Temperature, SSH, Syslog, Boot loader and more…

To check cpu of Maipu Router –

First enable , spy cpu and check cpu enable.

Router# spy cpu
Router# monitor cpu

Router(config)# check cpu enable

Then perform –

Show cpu , sh cpu monitor, show cpu history

Memory

Show memory – for memory

Temperature

You can see temperature on Maipu routers above 2800 series, like 2824, 3800,7200.

 sh environment

        CPU Temperature is 54°C

        MainBoard Temperature is 33°C

You can poll these values using any NMS. For this you require Maipu MIBs.

SSH

Many of Engineers want to enable SSH for secure communication , Here find the configuration required for SSH.

Step 1 -

 First create the crypto key:

router(config)#sshkeygen

        Generating host key ... ...

        Host key Generated!

After that perform below configuration :

hostname router

user admin privilege 15 password 0 admin

interface fastethernet0

 ip address 192.168.1.1 255.255.255.0

 exit

line ssh-vty 0 15

 privilege level 15

 password 0 admin

 login

 exit

            

ip ssh server

show command – show fingerprint

Output –

The public key sha1 fingerprint:

        Key length: 1024

        89:95:4f:7d:54:f0:6d:19:5a:c9:a7:6d:b5:f3:7d:e3:14:c4:8f:bd

The public key md5 fingerprint:

        Key length: 1024

        4e:ea:be:3e:b0:95:04:47:08:7f:fb:bc:a0:23:39:04

Boot Loader

To check which is your booting IOS or IOS preference-

router(config-fs)#show boot-loader

Basically this command will be helpful, when you have two IOS in flash. Some time you want to see which is active IOS and which IOS will be active after booting.

Syslog

The log messages are graded from level 0 to level 7 according to the

severity levels. Level 0 means the message level is the most severe. By

default, the information of level 0 -7 is all printed to the console interface;

if the terminal monitor command is configured on the telnet terminal;

the information of level 0-5 is written to the memory file; the information

of level 0-4 are written into the flash file; the information of level 0-5 is

sent to the log server.

router(config)#logging file ?    ### you can define level of logging ###

<0-7> Logging severity level

alerts                             Immediate action needed (severity=1)

critical                           Critical conditions (severity=2)

debugging                      Debugging messages (severity=7)

emergencies                   System is unusable (severity=0)

errors Error                   conditions (severity=3)

informational                  Informational messages (severity=6)

notifications                    Normal but significant conditions (severity=5)

warnings                       Warning conditions (severity=4)

The information levels are defined as follows:

Level Key Word Description

0   emergencies The system is unusable.

1   alerts You need to take action at once.

2   critical The critical statue

3   errors The error statue

4   warnings The warning status

5   notifications Normal status, but needs to be noticed

6   informational The informational messages

7   debugging The debugging information

More on /off

When you want to take some capture from your telnet session and your configuration is too long. Then many time you need to hit space button.

Here you can type – more off – in priviledge mode

It will not break configuration into pages.

Then again more on  - for normal usage

                                                                                      

Hope this basic information will be useful for you.
