**設定 [#x6df873d]
-eth0が返す値を設定
for i in `ls /sys/class/net/ | grep 'eth\|ens\|eno'`;
do echo "enabling lldp for interface: $i";
lldptool set-lldp -i $i adminStatus=rxtx;
lldptool -T -i $i -V sysName enableTx=yes;
lldptool -T -i $i -V portDesc enableTx=yes;
lldptool -T -i $i -V sysDesc enableTx=yes;
lldptool -T -i $i -V sysCap enableTx=yes;
lldptool -T -i $i -V mngAddr enableTx=yes;
done
-eth0のアドレスを設定
lldptool -T -i eth0 -V mngAddr ipv4=[IPADDR]
~
実行例~
# lldptool -T -i eth0 -V mngAddr ipv4=192.168.1.10
ipv4 = 192.168.1.10
-設定の有効化
# systemctl restart lldpad.service
-設定結果の確認
# lldptool get-tlv -i eth0
