익스트림 스위치 os 업그레이드 – tftp 서버 이용 –

TFTP 서버를 이용한 EXOS 업그레이드

* 작업환경
모델: summit x440-24p, IP 주소:192.168.0.10
TFTP server : 192.168.0.2

작업에 사용한 스위치는 한번도 사용하지 않은 장비로, 아무런 설정이 되어 있지 않은 상태.

1. 장비 os 확인

* X440-24p.1 # sh switch

Primary ver:      15.5.3.4
Secondary ver:    15.5.3.4

Config Selected:  NONE
Config Booted:    Factory Default

현제, primary, secondary 부트 이미지 모두 15.5.3.4 임을 확인할 수 있다.

2. Mgmt 포트에 ip 주소 할당하고, ssh 접속가능한지 확인

* X440-24p.3 # configure vlan mgmt ip address 192.168.0.10/24
* X440-24p.14 # sh management

                                 : Access Profile : not set
SSH Access                       : ssh module not loaded.
Web access                       : Disabled (tcp port 80)
                                 : Access Profile : not set

                                 : Access Profile : not set
SNMP Compatibility Options       :
    GETBULK Reply Too Big Action : Too Big Error

SNMP traps:     Sent   0       AuthTraps Enabled
SNMP inform:    Sent   0       Retries   0       Failed 0

ssh 모듈이 없으므로, 설치해야 scp를 이용가능하다. 그래서, tftp를 이용하기로 한다.

3. tftp서버를 윈도우에 실행하고 업그레이드할 이미지를 스위치로 전송한다.

tftp 서버와 스위치간 통신을 확인해본다.

* X440-24p.17 # ping vr vr-Mgmt 192.168.0.2
Ping(ICMP) 192.168.0.2: 4 packets, 8 data bytes, interval 1 second(s).
16 bytes from 192.168.0.2: icmp_seq=0 ttl=128 time=0.779 ms
16 bytes from 192.168.0.2: icmp_seq=1 ttl=128 time=10 ms
16 bytes from 192.168.0.2: icmp_seq=2 ttl=128 time=0.632 ms
16 bytes from 192.168.0.2: icmp_seq=3 ttl=128 time=0.673 ms

--- 192.168.0.2 ping statistics ---
4 packets transmitted, 4 packets received, 0% loss
round-trip min/avg/max = 0/3/10 ms

두번째 파티션이 비활성이므로, 그곳에 이미지를 설치한다는 메시지가 보인다.

* X440-24p.28 # download image 192.168.0.2 summitX-16.2.2.4-patch1-3.xos vr vr-Mgmt
Note: The inactive partition (secondary) will be used for installation.
Do you want to install image after downloading? (y - yes, n - no, <cr> - cancel) Yes

Downloading to Switch........................................
Installing to secondary partition!

Installing to Switch.......................................
Image installed successfully
This image will be used only after rebooting the switch!

4. 이제, secondary 파티션으로 부팅하도록하고 스위치를 재부팅한다.

* X440-24p.29 # use image secondary
* X440-24p.30 # reboot
No default configuration database has been selected to boot up the system.
Save configuration will set the new configuration as the default database.

Do you want to save configuration changes to currently selected configuration
file (primary.cfg) and reboot?
(y - save and reboot, n - reboot without save, <cr> - cancel command) Yes
Saving configuration on master .............. done!

5. 재부팅후 부트이미지 확인

secondary image가 업그레이드 되었고, 부팅에 사용되었음을 볼 수 있다.
