This can be done by “telnet” command. This command will take us into the root of VPN Circuit
of TRIMAX who is principal service provider of VPN. The company has provided us the id and
password to check the router at our end by User Access Verification procedure as follows. This
is done by giving the command
$telnet xxx.xxx.xxx.x (enter I.P Address of LAN)
When prompted for a password, enter the one associated. Then enable modification by entering
command ‘en’. Again it will be prompted for enable password: enter the root/enable password.
Now it will be in root folder. Issue the command “sh ip int brief” (for seeing the IP protocol
information in brief).
The following exercise is given on the basis of actual commands or information and the
operators are required to verify the status of the router. If Fast Ethernet 0/0 down then check
MODEM lead or If serial router 0/1/0 is down then check all leads of the router also.
EXAMPLE No. 1
operator@DELHI-INTERNET ~]$ telnet router-ip [example: 192.168.50.1]
Trying router ip...
Connected to router-ip.
Escape character is '^]'.
