FC网络中ISL链路的建立

在经典以太网中,我们需要有Trunk链路来承载多VLAN,而在FC网络中,我们也需要用ISL链路来承载多VSAN。下面是具体配置。

这里以两条链路做san-port-channel的形式,将Nexus 5000与MDS做ISL Trunking,放行vlan1和vlan200。

san-port-channel id:22

vsan:1,200

  • 配置vsan database:

Nexus 5000和MDS上:

vsan database

vsan 200

exit

  • 创建san-port-channel

Nexus 5000上:

int san22

channel mode active

sw mode e

sw trunk mode on

sw trunk allow vsan 1

sw trunk allow vsan add 200

no shut

exit

MDS上:

int po22

channel mode active

sw mode e

sw trunk mode on

sw trunk allow vsan 1

sw trunk allow vsan add 200

no shut

  • 将物理口加入san-port-channel端口组

Nexus 5000上:

首先show int bri检查是否有端口处于fc模式下,如果没有:

slot 2  —  模块插槽编号

port 1-16 type fc  —  更改1-16口模式为fc

poweroff module 2  —  模块2下电,请注意,这将中断业务!

no poweroff module 2  —  模块2上电,请在上一命令执行后10秒再操作

随后:

int fc2/1-2

chan 22 f

no shut

MDS上:

int fc2/1-2

chan 22 f

no shut

最后show int bri看端口状态是否为trunking,以及show int po 22 / san22看是VSAN是否有up起来:

MDS2# show interface port-channel 22
port-channel 22 is trunking
Hardware is Fibre Channel
Port WWN is 24:16:00:0d:ec:4a:80:00
Admin port mode is E, trunk mode is on
snmp link state traps are enabled
Port mode is TE
Port vsan is 1
Speed is 4 Gbps
Trunk vsans (admin allowed and active) (1,200)
Trunk vsans (up) (1,200)
Trunk vsans (isolated) ()
Trunk vsans (initializing) ()
