Summary of typical router configuration commands

Router configuration-CGMP

To configure cgmp on a cisco router:

Dallasr1> (config-if) # ip cgmp

Configure a multicast router to add it to a specific multicast group:

Dallasr1> (config-if) # ip igmp join-group-address

Disable CGMP:

Dallasr1> (config-if) # no ip cgmp

Start the cgmp on the switch:

Dallasr1> (enable) set cgmp enable

Verify the configuration of cgmp on the Catalyst Switch:

 
 

  
  
catalystla1>(enable) show config  
  
  
set prompt catalystla1> 
  
  
set interface sc0 192.168.1.1 255.255.255.0  
  
  
set cgmp enable 
 
 

CGMP exit settings:

Dallas_SW (enable) set cgmp leave

Router configuration-privileged level

Modify the control port password on a Cisco device:

 
 

  
  
R1(config)# line console 0  
  
  
R1(config-line)# login  
  
  
R1(config-line)# password Lisbon  
  
  
R1(config)# enable password Lilbao  
  
  
R1(config)# login local  
  
  
R1(config)# username student password cisco 
 
 

Set the console and vty port Session Timeout on the Cisco device:

 
 

  
  
R1(config)# line console 0  
  
  
R1(config-line)# exec-timeout 5 10  
  
  
R1(config)# line vty 0 4  
  
  
R1(config-line)# exec-timeout 5 2 
 
 

Set the privilege level on a Cisco device:

 
 

  
  
R1(config)# privilege configure level 3 username  
  
  
R1(config)# privilege configure level 3 copy run start  
  
  
R1(config)# privilege configure level 3 ping  
  
  
R1(config)# privilege configure level 3 show run  
  
  
R1(config)# enable secret level 3 cisco 
 
 

Use the privilege command to define the commands used at the privileged level:

Router (config) # privilege mode level command

Set the user privilege level:

 
 

  
  
router(config)# enable secret level 3 dallas  
  
  
router(config)# enable secret san-fran  
  
  
router(config)# username student password cisco 
 
 

Flag settings and display:

R1 (config) # banner motd 'unauthorized access will be prosecuted! '

Set vty access:

 
 

  
  
R1(config)# access-list 1 permit 192.168.2.5  
  
  
R1(config)# line vty 0 4  
  
  
R1(config)# access-class 1 in 
 
 

Configure HTTP access:

 
 

  
  
Router3(config)# access-list 1 permit 192.168.10.7  
  
  
Router3(config)# ip http sever  
  
  
Router3(config)# ip http access-class 1  
  
  
Router3(config)# ip http authentication local  
  
  
Router3(config)# username student password cisco 
 
 

To enable HTTP access, type the following command:

Switch (config) # ip http sever

Start and verify port security with setCL1 on the set command-based switch:

Switch (enable) set port security mod_num/port_num... Enable mac address

Switch (enable) show port mod_num/port_num

Start and verify port security on the CiscoIOS command-based switch:

 
 

  
  
switch(config-if)# port secure [mac-mac-count maximum-MAC-count]  
  
  
switch# show mac-address-table security [type module/port] 
 
 

Use the access-list command to create a record in the standard traffic filtering table:

Router (config) # access-list-number {permit | deny} source-address [source-address]

Use the access-list command to create a record in the extended traffic filtering table:

Router (config) # access-list-number {permit | deny {protocol | protocol-keyword }}{ source-wildcard | any} {destination-wildcard | any} [protocol- specific options] [log]

Router configuration-route update

For in-band route updates, the most basic command format for configuring route updates is:

R1 (config-router) # distribute-list access-list-number | name in [type number]

For out-of-band route updates, the most basic command format for configuring route updates is:

R1 (config-router) # distribute-list access-list-number | name out [interface-name] routing-process | autonomous-system-number

Router configuration-SNMP

Set snmp Command Options:

Set snmp community {read-only | ready-write | read-write-all} [community_string]

The format of the set snmp trap Command is as follows:

 
 

  
  
set snmp trap {enable|disable}  
  
  
[all|moudle|classis|bridge|repeater| auth|vtp|ippermit|vmps|config|entity|stpx]  
  
  
set snmp trap rvcr_addr rcvr_community 
 
 

Enable the SNMP chassis trap:

Console> (enable) set snmp trap enable chassis

Enable all SNMP chassis traps:

Console> (enable) set snmp trap enable

Disable the SNMP chassis trap:

Console> (enable) set snmp trap disable chassis

Add a record to the SNMP Trap receiving table:

Console> (enable) set snmp trap 192.122.173.42 public

Show snmp output result.

Output result of the command set snmp rmon enable.

Display SPAN information:
