vlan 沒用?
我有 2 台主機,通過交換機連接。交換機上沒有配置vlan。
在主機 A 上:
5: enp5s0f1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000 link/ether 0c:c4:7a:58:ef:95 brd ff:ff:ff:ff:ff:ff inet 192.168.10.11/24 brd 192.168.10.255 scope global enp5s0f1 valid_lft forever preferred_lft forever inet 192.168.10.10/24 scope global secondary enp5s0f1 valid_lft forever preferred_lft forever inet6 fe80::ec4:7aff:fe58:ef95/64 scope link valid_lft forever preferred_lft forever [root@ceph-node1 ~]# ip addr show enp5s0f1.1001 24: enp5s0f1.1001@enp5s0f1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000 link/ether 0c:c4:7a:58:ef:95 brd ff:ff:ff:ff:ff:ff inet 172.16.0.1/24 scope global enp5s0f1.1001 valid_lft forever preferred_lft forever inet6 fe80::ec4:7aff:fe58:ef95/64 scope link valid_lft forever preferred_lft forever
在主機 B 上:
5: enp5s0f1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000 link/ether 0c:c4:7a:59:a9:5b brd ff:ff:ff:ff:ff:ff inet 192.168.10.12/24 brd 192.168.10.255 scope global enp5s0f1 valid_lft forever preferred_lft forever inet6 fe80::ec4:7aff:fe59:a95b/64 scope link valid_lft forever preferred_lft forever [root@ceph-node2 ~]# ip addr show enp5s0f1.1001 8: enp5s0f1.1001@enp5s0f1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000 link/ether 0c:c4:7a:59:a9:5b brd ff:ff:ff:ff:ff:ff inet 172.16.0.2/24 scope global enp5s0f1.1001 valid_lft forever preferred_lft forever inet6 fe80::ec4:7aff:fe59:a95b/64 scope link valid_lft forever preferred_lft forever
主機 A 在非 vlan 介面上 ping 主機 B:
[root@ceph-node1 ~]# ping 192.168.10.12 PING 192.168.10.12 (192.168.10.12) 56(84) bytes of data. 64 bytes from 192.168.10.12: icmp_seq=1 ttl=64 time=0.169 ms 64 bytes from 192.168.10.12: icmp_seq=2 ttl=64 time=0.241 m
s
但是當 A 在 VLAN 介面上 ping 主機 B
[root@ceph-node1 ~]# ping 172.16.0.2 PING 172.16.0.2 (172.16.0.2) 56(84) bytes of data. From 172.16.0.1 icmp_seq=1 Destination Host Unreachable From 172.16.0.1 icmp_seq=2 Destination Host Unreachable
作業系統是 Cents7
請給我線索來解決這個問題

如果標記的數據包不屬於在交換機埠上配置的 VLAN,則交換機會丟棄這些數據包。
因此,如果您在伺服器上使用 vlan,則可以在交換機上設置 vlan。
