Dear all,
I have 2 Cisco Nexus 5000 with each 2 Nexus 2000 in FEX Mode. My Vlan are all in fabric mode.
I would tried to connect a catalyst 3750-X and a nexus 2K together in trunk with filter vlan.
NEXUS 2000 <== Port-Channel ===> Cisco 3750X
N2K :
Po: switchport mode trunk
switchport trunk allowed vlan 10,20,30
Interface : e101/1/1 & e102/1/1
switchport mode trunk
channel-group 1 mode active
3750X
Po : switchport mode trunk
switchport trunk allowed vlan 10,20,30
spanning-tree bpdufilter enable
interfaces : Gi0/1 & Gi0/2
switchport mode trunk
switchport trunk allowed vlan 10,20,30
channel-group 1 mode active
It doesn't work in allowed vlan (not connection, nothing all) but without the command allowed vlan, my po and my interfaces are up. I tried wihtout LACP in mode etherchannel only but it was the same result.
Questions :
- Could you tell me if this a mechanism with the fabric mode or if there is something to add or modify ?
- If I have a VLAN 40 from my 3750X but not in the 2K, it is forwarding accross my interface ?
Thanks for your help.
Have a nice day,
Matthieu
