Trunk from PC5448 to Cisco 3750 over FC

Hi guys,

Thanks for support.

I need some help for configure a trunkbetween twoPC5448and 2 groups ofCiscoSytem3750instackconfiguration.

I explainmy scenario:

Phisical:

2 Dell PC 5448 for Server Network traffic interconnected with 2 SFP (FC Cable)

3 Cisco System 3750 in stack with SFP (FC Cable) uplink for PC 5448#1 for Client Network Traffic

3 Cisco System 3750 in stack with SFP (FC Cable) uplink for PC 5448#2 for Client Network Traffic

Logical:

Dell PC5448 trunk to CS3750 VLAN 1 (NATIVE)

VLAN 50 Tagged

VLAN 10 Tagged

VLAN 8 Tagged

Schema:

I setup the trunk interconnection for PC5548:

console# config

console(config)# interface ethernet g47

console(config-if)# switchport mode trunk

console(config-if)# switchport trunk allowed vlan add 50

console(config-if)# switchport trunk allowed vlan add 8

console(config-if)# switchport trunk allowed vlan add 10

console (config-if)# switchport trunk native vlan 1

console# config

console(config)# interface ethernet g48

console(config-if)# switchport mode trunk

console(config-if)# switchport trunk allowed vlan add 50

console(config-if)# switchport trunk allowed vlan add 8

console(config-if)# switchport trunk allowed vlan add 10

console (config-if)# switchport trunk native vlan 1

Working, but the 2 sfp connectionswork together?1 is in standbyandone works?

Nowi needtosetupthe connectionCS3750,someone can tell meif it isbetter to usetrunk modeorgeneral?

Thanks a lot.
