我正在配置vPC端到端直到我的服务器获得更多带宽，以下是我的场景
我看到一件奇怪的事情，那就是我在 N3k 交换机上配置了 vPC，然后我将 Linux 服务器配置为链路聚合802.3ad绑定，然后我重新启动服务器到目前为止一切正常，我可以看到正确的绑定配置/proc/net/bonding/bind0，我的服务器也开始 ping 但我发现我在 ping 中丢失了数据包，后来我在交换机上发现它的显示vpc已关闭，但想知道我是如何获得 ping 的？
N3k# show vpc 1
vPC status
----------------------------------------------------------------------
id Port Status Consistency Reason Active vlans
-- ---- ------ ----------- ------ ------------
134 Po1 down* success success -
后来我做了shut与no shut上Port-Channel 1并立即调出VPC
N3k# show vpc 1
vPC status
----------------------------------------------------------------------
id Port Status Consistency Reason Active vlans
-- ---- ------ ----------- ------ ------------
131 Po1 up success success 10,20,30
我的 VPC 域配置
vpc domain 204
peer-switch
role priority 10
peer-keepalive destination 10.29.0.51 source 10.29.0.50
auto-recovery
ip arp synchronize
这是我的 vPC 配置
interface Ethernet1/1
switchport mode trunk
switchport trunk allowed vlan 10,20,30
spanning-tree port type edge trunk
spanning-tree bpduguard enable
speed 10000
channel-group 1 mode active
interface port-channel1
switchport mode trunk
switchport trunk allowed vlan 10,20,30
speed 10000
vpc 1
这是我的 Linux 服务器配置
ifcfg-bond0
NAME=bond0
DEVICE=bond0
BOOTPROTO=none
ONBOOT=yes
BONDING_OPTS="mode=4 miimon=500 downdelay=1000 lacp_rate=1"
NM_CONTROLLED=no
ifcfg-bond0.10
NAME=bond0.10
DEVICE=bond0.10
BOOTPROTO=dhcp
VLAN=yes
ONPARENT=yes
NM_CONTROLLED=no
问题：
- 即使
vpc在交换机上关闭服务器如何ping通？ - 为什么我需要
shut/no shutvpc 来启动 vpc？这是正常的吗？ - 我在同一个 vpc 集群上安装了 30 台服务器，并且都有同样的问题，每次我必须去交换机并需要做端口通道
shut/no shut - 我在这里错过了什么吗？
更新 - 1
为了测试我重新启动服务器并发现服务器已启动但交换机 vpc 已关闭并且在交换机上我看到以下日志，这是一个奇怪的问题。

服务器端我看到以下错误
