4 基础环境部署

在两台Server服务器上,安装部署本次验证方案的所需要的基础软件。

补充说明:以”[root@server ~]#”为开头的命令表示两台服务器都要执行。

4.1 LLDP

在两台Server服务器上安装LLDP服务,如果是X710网卡要求网卡驱动版本大于2.3.6,然后配置网卡开启LLDP。

[root@server ~]# yum -y install epel-release
[root@server ~]# yum -y install lldpd
[root@server ~]# systemctl start lldpd
[root@server ~]# systemctl enable lldpd
[root@server ~]# lspci |grep -i ether
配置网卡开启LLDP
[root@server ~]# ethtool -i ens1f2
[root@server ~]# ethtool -i ens1f3
ethtool -i ens1f2
 ethtool -i ens1f3
[root@sever ~]# ethtool --set-priv-flags ens1f2 disable-fw-lldp on
[root@sever ~]# ethtool --set-priv-flags ens1f3 disable-fw-lldp on

4.2 安装iPerf3 

在2台Server服务器上安装iPerf3软件用来打流。

在3台服务器上上执行:
[root@server ~]# yum -y install iperf3
[root@server ~]# iperf3 -v
iperf 3.1.7
Linux compute-2 3.10.0-1160.62.1.el7.x86_64 #1 SMP Tue Apr 5 16:57:59 UTC 2022 x86_64
Optional features available: CPU affinity setting, IPv6 flow label, TCP congestion algorithm setting, sendfile / zerocopy, socket pacing

4.3 检查链路连接

所有交换机设备要提前检查和Server服务器之间的链路连接情况,确保交换机设备和Server服务器之间的链路连接没有问题,以下命令在所有交换机设备上执行。

admin@sonic:~$ sudo config cli-mode cli

Leaf4(config)# evpn-overlay enable
Leaf4(config)# vrf 456
Leaf4(config-vrf)# mac 60:eb:5a:00:86:22
Leaf4(config-vrf)# interface vlan 20
Leaf4(config-vlanif-10)# vrf 456
Leaf4(config)# vlan 20
Leaf4(config-vlan-10)# vni 20
