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# 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.
