[Linux] CentOS7 에서 LLDP 설정 및 동작 확인

[Linux] CentOS7 에서 LLDP 설정 및 동작 확인 1. LLDP 설치 및 실행 2. Link 에 LLDP 설정 및 설정 값 확인 3. LLDP 확인4. LLDP 설정 해제

연동 스위치의 포트에서 LLDP Enable 설정 필요

1. LLDP 설치 및 실행

• lldpad package 설치

  yum install -y lldpad

• lldpad daemon 실행

  systemctl start lldpad 

2. Link 에 LLDP 설정 및 설정 값 확인

• lldptool 명령어로 설정

  • lldptool set-lldp -i ens1f0 adminStatus=rxtx ;

  • lldptool -T -i ens1f0 -V sysName enableTx=yes;

  • lldptool -T -i ens1f0 -V portDesc enableTx=yes ;

  • lldptool -T -i ens1f0 -V sysDesc enableTx=yes;

  • lldptool -T -i ens1f0 -V sysCap enableTx=yes;

  • lldptool -T -i ens1f0 -V mngAddr enableTx=yes;

  [root@server ~]# lldptool get-lldp -i ens1f0 adminStatus
  adminStatus=rxtx
  [root@server ~]# lldptool set-lldp -i ens1f0 adminStatus=rxtx ;
  adminStatus = rxtx
  [root@server ~]# lldptool -T -i ens1f0 -V sysName enableTx=yes;
  enableTx = yes
  [root@server ~]# lldptool -T -i ens1f0 -V portDesc enableTx=yes ;
  enableTx = yes
  [root@server ~]# lldptool -T -i ens1f0 -V sysDesc enableTx=yes;
  enableTx = yes
  [root@server ~]# lldptool -T -i ens1f0 -V sysCap enableTx=yes;
  enableTx = yes
  [root@server ~]# lldptool -T -i ens1f0 -V mngAddr enableTx=yes;
  enableTx = yes
  [root@server ~]#
  

• lldptool 명령어로 설정 값 확인

  • lldptool get-lldp -i ens1f0 adminStatus

  [root@server ~]# lldptool get-lldp -i ens1f0 adminStatus
  adminStatus=rxtx
  

3. LLDP 확인

• LLDP 링크 연동 정보 확인

  • lldptool -i ens1f0 -t -n

  [root@server ~]# lldptool -i ens1f0 -t -n
