[네트워크관리사 2급 실기] 라우터 문제 총정리

서브넷마스크설정 문제

interface fastEthernet 0/0

ip address 192.168.200.2 255.255.255.252

Router> enable (en)
Router# config terminal (conf t)
Router(config)# interface Ethernet 0 (int e0)
Router(config-if)# ip address 192.168.200.2 255.255.255.252 (ip add ~)
Router(config-if)# ip directed-broadcast
Router(config-if)# exit
Router(config)# exit
Router# copy r s

2. ethernet 의 ip address를 192.168.2.1/30와 192.168.3.1/30 secondary로 설정하고 저장하시오.

Router> enable (en)
Router# config terminal (conf t)
Router(config)# interface Ethernet 0 (int e0)
Router(config-if)# ip address 192.168.200.2 255.255.255.252 (ip add ~)

Router(config-if)# exit
Router(config)# exit
Router# copy r s

서브넷 마스크를 직접 기입해줘야 한다!! 잊지말기

 

대역폭 문제

1. serial 0의 대역폭을 2048로 설정하고 NVRAM에 저장하시오.

Router> enable
Router# config terminal
Router(config)# interface serial 0/0
Router(config-if)# bandwidth 2048
Router(config-if)# exit
Router(config)# exit
Router# copy r s

2. serial 0의 clock rate를 72k로 설정하고 NVRAM에 저장하시오.

Router> enable
Router# config terminal
Router(config)# interface serial 0/0
Router(config-if)# clock rate 72000
Router(config-if)# exit
Router(config)# exit
Router# copy r s

 

 

확인/변경문제

1. 인터페이스 정보를 확인하라

Router> enable
Router# show interface
Router# copy r s

2. 접속한 사용자를 확인하라

Router> enable
Router# show user
Router# copy r s

3. 라우팅 테이블을 확인하라

Router> enable
Router# show ip route
Router# copy r s

4. 플래쉬를 확인하라

Router> enable
Router# show flash
Router# copy r s

5. 호스트 네임을 ICQA로 변경하라

Router> enable
Router# config terminal
Router(config)# hostname ICQA
Router(config)# exit
Router# copy r s

6. 소프트웨어 버전과 IOS 버전등을 확인하라

Router> enable
Router# show version
Router# copy r s

7. CPU process list를 확인하라

Router> en
Router# show process
Router# copy r s

 

설정문제

1. ethernet 0의 description을 ICQA로 설정하고 NVRAM에 저장하시오.

Router> enable
Router# config terminal
Router(config)# interface ethernet 0/0
Router(config-if)# description ICQA
Router(config-if)# exit
Router(config)# exit
Router# copy r s

2. default-gateway를 설정하고 저장하시오. (ip: 192.168.0.10)

Router> enable
Router# config terminal
Router(config)# ip default-gateway 192.168.0.10
Router(config)# exit
Router# copy r s

3. router1 telnet에 접근하는 password를 "telpass"로 설정하고 상태를 저장하시오.

Router> enable
Router# config terminal
Router(config)# line vty 0 4
Router(config-line)# password telpass 
Router(config-line)# login
Router(config-line)# exit
Router(config)# exit
Router# copy r s

4. telnet에 5분 50초 동안 신호가 없을 시 해당 세션을 자동으로 종료하도록 라우터를 설정하시오.

Router> enable
Router# config terminal
Router(config)# line vty 0 4
Router(config-line)# exec-timeout 05 50
Router(config-line)# exit
Router(config)# exit
Router# copy r s

5. router1 console의 패스워드를 ICQACon으로 설정하고 저장하시오.

Router> enable
Router# config terminal
Router(config)# line console 0/0
Router(config-line)# password ICQACon
Router(config-line)# exit
Router(config)# exit
Router# copy r s

6. router2의 interface serial 0를 활성화시키고 저장하시오.

Router> enable
Router# config terminal
Router(config)# interface serial 0/0
Router(config-if)# no shutdown
Router(config-if)# exit
Router(config)# exit
Router# copy r s

7. hostname을 network2로 변경하고, console 0의 password를 router5로 변경하고 login하라.

Router> enable
Router# config terminal
Router(config)# hostname network2
Router(config)# line console 0/0
Router(config-line)# password route5
