nmcli 를 이용한 bonding 구성

구성 환경

redhat(centos)에서 nmcli 를 이용한 bonding(mode 4, LACP) 구성

 

준비

nmcli를 사용하기 위해서는 NetworkManager 서비스가 실행중이어야 한다

> systemctl status NetworkManager

> systemctl enable NetworkManager 

> systemctl start NetworkManager

 

1. bonding 인터페이스 생성

> nmcli connection add type bond con-name bond0 ifname bond0 bond.options "mode=4,miimon=100" 'bond0' (4e82d3ae-3103-4c0d-b988-f658a26db086) 연결이 성공적으로 추가되었습니다.

2. 확인

> nmcli con show NAME    UUID                                  TYPE      DEVICE bond0   4e82d3ae-3103-4c0d-b988-f658a26db086  bond      bond0 ens160  ac81fe80-2710-4bbc-b232-257b89942e87  ethernet  ens160 ens161  dbf76be3-b941-4c83-94d1-2bb551af35ca  ethernet  --

3.  slave 인터페이스 구성

3.1 slave 인터페이스를 구성할 인터페이스 확인(여기서는 ens224, ens256 인터페이스 사용)

> nmcli device status DEVICE  TYPE      STATE                          CONNECTION ens160  ethernet  연결됨                         ens160 bond0   bond      연결 중 (IP 설정 가져오는 중)  bond0 ens161  ethernet  연결 끊겼음                    -- ens224  ethernet  연결 끊겼음                    -- ens256  ethernet  연결 끊겼음                    -- lo      loopback  관리되지 않음                  --

3.2 slave 인터페이스 구성

> nmcli con add type ethernet slave-type bond con-name bond0-ens224 ifname ens224 master bond0 'bond0-ens224' (be06d502-9899-4187-ab04-2b106a36c1a5) 연결이 성공적으로 추가되었습니다. > nmcli device status DEVICE  TYPE      STATE          CONNECTION ens160  ethernet  연결됨         ens160 bond0   bond      연결됨         bond0 ens224  ethernet  연결됨         bond0-ens224 ens161  ethernet  연결 끊겼음    -- ens256  ethernet  연결 끊겼음    -- lo      loopback  관리되지 않음  -- > nmcli con add type ethernet slave-type bond con-name bond0-ens256 ifname ens256 master bond0 'bond0-ens256' (d431ed50-e397-4f73-8aa9-d450331e826e) 연결이 성공적으로 추가되었습니다. > nmcli device status DEVICE  TYPE      STATE          CONNECTION ens160  ethernet  연결됨         ens160 bond0   bond      연결됨         bond0 ens224  ethernet  연결됨         bond0-ens224 ens256  ethernet  연결됨         bond0-ens256 ens161  ethernet  연결 끊겼음    -- lo      loopback  관리되지 않음  --

4. IP 설정

> nmcli con modify bond0 ipv4.method manual ipv4.addresses '10.10.10.176/24' > nmcli con modify bond0 ipv4.gateway '10.10.10.1'  > nmcli con modify bond0 ipv4.dns '8.8.8.8' >  nmcli con up bond0 연결이 성공적으로 활성화되었습니다 (master waiting for slaves) (D-버스 활성 경로: /org/freedesktop/NetworkManager/ActiveConnection/15) > nmcli device show bond0 GENERAL.DEVICE:                         bond0 GENERAL.TYPE:                           bond GENERAL.HWADDR:                         00:50:56:2B:94:55 GENERAL.MTU:                            1500 GENERAL.STATE:                          100 (연결됨) GENERAL.CONNECTION:                     bond0 GENERAL.CON-PATH:                       /org/freedesktop/NetworkManager/ActiveC> IP4.ADDRESS[1]:                         10.10.10.176/24 IP4.GATEWAY:                            10.10.10.1 IP4.ROUTE[1]:                           dst = 10.10.10.0/24, nh = 0.0.0.0, mt => IP4.ROUTE[2]:                           dst = 0.0.0.0/0, nh = 10.10.10.1, mt = > IP4.DNS[1]:                             8.8.8.8 IP6.ADDRESS[1]:                         fe80::9cfa:59f0:feef:cf2/64 IP6.GATEWAY:                            -- IP6.ROUTE[1]:                           dst = fe80::/64, nh = ::, mt = 1024

5. 확인

모든 인터페이스의 churn 상태가 none 인지 확인,

만약 상태가 churned 상태이면 네트워크쪽 LACP 구성 확인 필요
