안녕하세요.
오늘은 Cisco IOS Download 받을때 Cisco가 권장하는 IOS 버전에 대해서 알아보겠습니다.
1. 아래 시스코 사이트에 접속 합니다.
https://software.cisco.com/download/home
2. 현재 구매한 장비 모델을 입력 합니다.
3. cisco XE software 버튼을 클릭 합니다.
4. *에 으미가 현재 시점에서 시스코가 권장하는 IOS 버전 입니다.
지금까지 Cisco IOS recommendation 글을 읽어주셔서 감사합니다.

PC에 IP를 10.1.1.2 설정하고 케이블을 스위치 VLAN1 포트에 연결합니다.
지금까지 C9300 스위치에 SSH version2를 설정하고 테스트 하는 방법에 대해서 알아보았습니다

안녕하세요.
오늘은 C9300 Stack 스위치 IOS Upgrade에 대해서 알아보도록 하겠습니다.
현재 버전을 확인 하기 위해서 show version을 입력 합니다.

시스코 홈페이지를 접속해서 현재 시점에서 C9300-24T에 IOS 추천 버전을 확인 합니다.
https://software.cisco.com/download/home/286313829/type/286308587/release/17.12.4?i=!pp
현재 시스코 추천 IOS는 17.12.04 입니다.
이미지 파일을 다운로드 합니다.
USB를 준비 합니다.
USB에 이미지 파일을 복사 합니다.
그리고 USB를 Master SW에 연결 합니다.
첫번째 로그를 보시면 USB0이 정상적으로 인식 된걸 확인 할 수 있습니다.
그리고 file를 확인해 보면 아래와 같이 2개 파일을 확인 가능합니다.
npe - no payload 이미지 파일입니다.
우리는 payload 이미지 파일을 설치 해보겠습니다

1. usb0에 이미지 파일을 복사하기 전에 불필요한 파일을 삭제합니다.

2. usb에 있는 이미지 파일을 복사 합니다.

3. 이미지 파일이 정상적으로 복사가 되었는지 무결성 검사를 합니다.

| Switch#verify /md5 flash:/cat9k_iosxe.17.12.04.SPA.bin ................................... verify /md5 (flash:/cat9k_iosxe.17.12.04.SPA.bin) = 1e3ab8c2357b33784373b626c190b907 |
4. install mode는 packages.conf 파일을 사용하기 때문에 설정값이 제대로 맞는지 다시 한번 확인합니다.
| Switch(config)#boot system flash:packages.conf Switch#show boot system --------------------------- Switch 1 --------------------------- Current Boot Variables: BOOT variable = flash:packages.conf; Boot Variables on next reload: BOOT variable = flash:packages.conf; Manual Boot = no Enable Break = no Boot Mode = DEVICE iPXE Timeout = 0 --------------------------- Switch 2 --------------------------- Current Boot Variables: BOOT variable = flash:packages.conf; Boot Variables on next reload: BOOT variable = flash:packages.conf; Manual Boot = no Enable Break = no Boot Mode = DEVICE iPXE Timeout = 0 Switch# wr |
5. IOS를 업그레이드 합니다.
이미지 파일이 Standby SW에 복사를 시도 합니다. 그리고 IOS 업그레이드 시작합니다.
| Switch# install add file flash:cat9k_iosxe.17.12.04.SPA.bin activate commit Copying flash:cat9k_iosxe.17.12.04.SPA.bin from Switch 1 to Switch 1 2 *Oct 24 07:44:43.996: %INSTALL-5-INSTALL_START_INFO: Switch 1 R0/0: install_mgr: Started install add_activate_commit flash:cat9k_iosxe.17.12.04.SPA.bi |
6. 복사가 완료 되고 IOS 버전 업그레이드를 시작 합니다. 그리고 Y를 선택합니다.
시간이 꽤 걸립니다. 인내심을 가지고 기다립니다.

안녕하세요.
오늘은 C9300 스위치 Stack 설치에 대해서 알아보도록 하겠습니다.
아래 사진처럼 C9300 스위치를 2대 준비합니다.
Stack 케이블을 아래 사진처럼 연결 합니다.
그리고 전원을 연결 합니다.
부팅이 완료 되면 아래처럼 show switch 입력하면 자동으로 Stack 설정이 완료 된것을 확인 할수 있습니다.
| Switch#show switch Switch/Stack Mac Address : 9c66.977a.e000 - Local Mac Address Mac persistency wait time: Indefinite H/W Current Switch# Role Mac Address Priority Version State ------------------------------------------------------------------------------------- *1 Active 9c66.977a.e000 1 V08 Ready 2 Standby 9c66.977a.e080 1 V08 Ready |
2대 스위치중에서 어떤 스위치가 Master로 선택 되는지는 알고리즘에 의해서 선정 됩니다.
Master Switch Election
The stack behaves as a single switching unit that is managed by a master switch elected from one of the member switches. The master switch automatically creates and updates all the switching and optional routing tables. Any member of the stack can become the master switch. Upon installation, or reboot of the entire stack, an election process occurs among the switches in the stack. There is a hierarchy of selection criteria for the election.
1. User priority - The network manager can select a switch to be master.
2. Hardware and software priority - This will default to the unit with the most extensive feature set. The Cisco Catalyst 3750 IP Services (IPS) image has the highest priority, followed by Cisco Catalyst 3750 switches with IP Base Software Image (IPB).
Catalyst 3750-E and Catalyst 3750-X run the Universal Image. The feature set on the universal image is determined by the purchased license. The "show version" command will list operating license level for each switch member in the stack.
3. Default configuration - If a switch has preexisting configuration information, it will take precedence over switches that have not been configured.
4. Uptime - The switch that has been running the longest is selected.
5. MAC address - Each switch reports its MAC address to all its neighbors for comparison. The switch with the lowest MAC address is selected

show switch에서는 switch1이 마스터 스위치 선택되었지만 실제 C9300 스위치 두대중에서 어떤 스위치가 마스터인지 확인이 불가능 합니다.
show version 실행합니다.
첫번째 정보가 Switch1에 대한 정보 입니다
두번째 정보가 Switch2에 대한 정보 입니다.
Switch1에 Serial 정보를 실제 장비에 시리얼 번호를 확인 합니다.
| Base Ethernet MAC Address : Motherboard Assembly Number : Motherboard Serial Number : XXXXXXXXX Model Revision Number : Motherboard Revision Number : Model Number : C9300-24T System Serial Number : XXXXXXXX CLEI Code Number : Switch Ports Model SW Version SW Image Mode ------ ----- ----- ---------- ---------- ---- * 1 41 C9300-24T 17.12.03 CAT9K_IOSXE INSTALL 2 41 C9300-24T 17.12.03 CAT9K_IOSXE INSTALL Switch 02 --------- Switch uptime : 25 minutes Base Ethernet MAC Address : Motherboard Assembly Number : Motherboard Serial Number : YYYYYYYYY Model Revision Number : Motherboard Revision Number : Model Number : C9300-24T System Serial Number : YYYYYYYYY Last reload reason : CLEI Code Number : |
그리고 장비에 라벨을 프린터 해서 붙입니다.
장비가 재부팅 되더라도 항상 Switch1에 Master로 선정하기 위해서 아래 처럼 Switch Priority 값을 수정 합니다.
| Switch#switch 1 priority 14 Switch#switch 2 priority 13 Switch#show switch Switch# Role Mac Address Priority Version State ------------------------------------------------------------------------------------- *1 Active 14 V08 Ready 2 Standby 13 V08 Ready |
그리고 장비에 설정값을 저장 합니다
| Switch#wr Building configuration... [OK] |
지금까지 C9300 Stack 관련해서 알아보았습니다.

안녕하세요.
오늘은 Cat9300L 스위치 라이센스를 CSSM에 등록하는 방법에 대해서 알아보겠습니다.
1. Traditional 방식
2. Smart License
3. Smart License Using Policy
위에 3가지 방법에 대해서는 추후에 자세히 설명 하도록 하겠습니다.
현재 구매한 스위치에 디폴트로 어떤 라이센스 방식을 사용 하는지 확인해보겠습니다.
아래 처럼 Smart License Using Policy 방식을 사용 하고 있습니다.
| TSIWL-CSW-01#show license status Utility: Status: DISABLED Smart Licensing Using Policy: Status: ENABLED |
현재 사용하고 있는 IOSXE버전은 아래와 같습니다.
| Switch Ports Model SW Version SW Image Mode ------ ----- ----- ---------- ---------- ---- * 1 29 C9300L-24T-4G 17.12.03 CAT9K_IOSXE INSTALL |
1. 라이센스를 등록하기전에 라이센스가 CSSM - Cisco Account에 등록 되어져 있어야 합니다.
2. CSSM서버에 통신이 가능한지 확인 합니다.
| TSIWL-CSW-01#telnet smartreceiver.cisco.com 443 Trying smartreceiver.cisco.com (72.163.15.144, 443)... Open |
3. 스위치에 기본 설정을 합니다
| TSIWL-CSW-01(config)#license smart transport smart TSIWL-CSW-01(config)#license smart url default TSIWL-CSW-01#wr |
4. CSSM 로그인후 New Token 클릭 합니다.
5. Create Token 클릭 합니다.
6. 생성된 키를 복사합니다
7. Key를 Cisco 스위치에 등록 합니다.
| TSIWL-CSW-01#license smart trust idtoken <copy the token> all force |
8. 라이센스 상태를 확인 합니다
Trust Code에보면 정상적으로 라이센스가 설치 된것을 확인 가능 합니다
| TSIWL-CSW-01#show license status Utility: Status: DISABLED Smart Licensing Using Policy: Status: ENABLED Account Information: Smart Account: **** you can see your SA account *** As of Oct 02 11:43:47 2024 UTC Virtual Account: *** the VA account also show *** Trust Code Installed: Active: PID:C9300L-24T-4G,SN: INSTALLED on Oct 02 11:43:35 2024 UTC Standby: PID:C9300L-24T-4G,SN: INSTALLED on Oct 02 11:43:36 2024 UTC |
9. CSSM에서 라이센스 확인하기
