cisco router configuration, cisco iso router configuration commands

Cisco IOS Router Commands

There are 3 modes operation the Cisco IOS.
·        Disabled mode
·        Enabled mode
·        Configuration mode

Disabled mode you can use a limited number of commands. This is used primarily to monitor the router.
Enabled mode is used to show configuration information, enter the configuration mode, and make changes to the configuration.
Configuration mode is used to enter and update the runtime configuration.
To get a list of the commands for the cisco type '?' at the prompt. Further information about any command, type the command followed by  '?'.

View Ethernet IP

Router#wr term

This will show the running configuration.
Within the configuration, see an interface ethernet 0 section:

interface Ethernet0

no ip directed-broadcast

View Serial IP

Router#wr term

Within the configuration, see an interface serial 0 section:

interface Serial0

ip broadcast-address
ip access-group 106 in
encapsulation frame-relay
bandwidth 56
no fair-queue
frame-relay map ip 500 IETF

View Default Route

Router#wr term

Within the configuration, see an ip route section. 

In the ip route section, look for a route:
ip route
The last ip address is the POP ip.

View Filters

Router#wr term

Under interface serial 0, look for:

ip access-group 104 in
ip access-group 105 out

Its means that access-group 104 is the inbound filter set and
access-group 105 is the outbound filter set.
Then, continue to look in the configuration for the access-list statements:

(Example for access-list statements)
access-list 104 deny   ip any
access-list 104 permit tcp any any established
access-list 104 permit tcp any eq ftp-data any gt 1023
access-list 104 permit udp any eq domain any gt 1023
access-list 104 permit udp any eq domain any eq domain
access-list 104 permit icmp any any
access-list 104 permit udp any eq snmp any gt 1023
access-list 105 deny   ip any
access-list 105 permit tcp any any established
access-list 105 permit tcp any any eq ftp
access-list 105 deny   udp any eq netbios-ns any
access-list 105 deny   udp any eq netbios-dgm any
access-list 105 permit ip any any

View Bandwidth

Router#wr term

Within the config, see an interface serial 0 section:

interface Serial0
ip address
ip broadcast-address
ip access-group 106 in
encapsulation frame-relay
bandwidth 56
no fair-queue
frame-relay map ip 500 IETF

Add a Static Route

Cisco#config t
Enter configuration commands, one per line.  End with CNTL/Z.
where: DEST.DEST.DEST.DEST = The destination network the static route is for
       MASK.MASK.MASK.MASK = The subnet mask of the destination network
       GATE.GATE.GATE.GATE = The gateway of the static route
Example route statement:
ip route
Cisco(config)#^Z (hit <control> z)

Write the entry to memory:

Cisco#wr mem
Building configuration...

Change Dial Number

Type en to put the router in enable mode:>en

The password should be the same as the one used to telnet in.


To view the router's configuration, type: config

There will be a line in the configuration that says:

dialer map IP speed 64 name LD3330 2707000

The 2707000 is the dial number.

NOTE: Record what interface the dialer map IP line is under because you will need to
use that interface when changing the number.

Type config t to configure from terminal. t

Enter configuration commands, one per line.  End with CNTL/Z.
Enter the interface that the dialer map IP line is under: BRI0

Add in the new dialer map IP line with the new phone number: map IP speed 64 name LD3330 [new number]

Now, remove the old dialer map IP line.
To remove a line, type no and then the line.
For example, to remove the old dialer map IP, type: dialer map IP speed 64 name LD3330 2707020

Now leave config mode: [control] z

Save changes: write mem
Building configuration...

Verify the new number is in the config: config

The new number should be in the dialer map IP line.

Turn Filters On and Off

To turn the filters off:

Router#configure terminal
Router(config)#interface Serial0
Router(config-if)#no ip access-group 104 in
Router(config-if)#no ip access-group 105 out
Router(config-if)# Hit CTRL-Z
Router#wr mem
Building configuration...

To turn the filters on:

Router#configure terminal
Router(config)#interface Serial0
Router(config-if)#ip access-group 104 in
Router(config-if)#ip access-group 105 out
Router(config-if)# Hit CTRL-Z
Router#wr mem
