For you information, here is what we did : Gi0/1 up up FRBC1VM01 # VMNIC 0 Gi0/2 up up FRBC1VM02 # VMNIC 0 Gi0/3 up up FRBC1VM03 # VMNIC 0 Gi0/4 up up FRBC1VM04 # VMNIC 0 Gi0/5 up up FRBC1VM05 # VMNIC 0 Gi0/6 down down FRBC1VM06 # VMNIC 0 Gi0/7 down down FRBC1VM07 # VMNIC 0 Gi0/8 down down FRBC1VM08 # VMNIC 0 Gi0/9 up up FRBC1VM09 # VMNIC 0 Gi0/10 up up FRBC1VM10 # VMNIC 0 Gi0/11 up up FRBC1VM11 # VMNIC 0 Gi0/12 up up FRBC1VM12 # VMNIC 0 Gi0/13 up up FRBC1VM13 # VMNIC 0 Gi0/14 down down FRBC1VM14 # VMNIC 0 Gi0/15 down down FRBC1VM15 # VMNIC 0 Gi0/16 down down FRBC1VM16 # VMNIC 0 Gi0/17 up up 4948-CORE1-FR # Gi1/0/9 Gi0/18 up up 4948-CORE1-FR # Gi1/0/10 Gi0/19 up up 4948-CORE2-FR # Gi1/0/9 Gi0/20 up up 4948-CORE2-FR # Gi1/0/10 Gi0/21 down down Gi0/22 down down Gi0/23 down down Gi0/24 down down Po10 up up 4948-CORE1-FR (Local : gi0/17-18 # Peer : Gi1/9-10) Po11 up up 4948-CORE2-FR (Local : gi0/19-20 # Peer : Gi1/9-10)
Some ports are down because there is currently no Blade connected to slot 6 / 7 / 8 / 14 / 15 / 16 Port 17 and 18 : Po10 connected to our external switch called Core1 Port 19 and 20 : Po11 connected to our external switch called Core2 The spanning-tree is handling the failover between the 2 port-channels. So far, all vlans trunk on po10 are in the forwarding state whereas on po11 state is blocking (except 666 due to our design) 3020-1-FR# sh spanning-tree int po10 Vlan Role Sts Cost Prio.Nbr Type ------------------- ---- --- --------- -------- -------------------------------- VLAN0001 Root FWD 3 128.128 P2p VLAN0002 Root FWD 3 128.128 P2p VLAN0004 Root FWD 3 128.128 P2p VLAN0016 Root FWD 3 128.128 P2p VLAN0017 Root FWD 3 128.128 P2p VLAN0032 Root FWD 3 128.128 P2p VLAN0070 Root FWD 3 128.128 P2p VLAN0090 Root FWD 3 128.128 P2p VLAN0666 Altn BLK 3 128.128 P2p 3020-1-FR# sh spanning-tree int po11 Vlan Role Sts Cost Prio.Nbr Type ------------------- ---- --- --------- -------- -------------------------------- VLAN0001 Altn BLK 3 128.136 P2p VLAN0002 Altn BLK 3 128.136 P2p VLAN0004 Altn BLK 3 128.136 P2p VLAN0016 Altn BLK 3 128.136 P2p VLAN0017 Altn BLK 3 128.136 P2p VLAN0032 Altn BLK 3 128.136 P2p VLAN0070 Altn BLK 3 128.136 P2p VLAN0090 Altn BLK 3 128.136 P2p VLAN0666 Root FWD 3 128.136 P2p Here is an example of g0/1, port connected to a blade-server : interface GigabitEthernet0/1 description FRBC1VM01 # VMNIC 0 switchport trunk encapsulation dot1q switchport trunk native vlan 2 switchport mode trunk speed 1000 spanning-tree portfast trunk end And the configuration for the first port-channel : interface GigabitEthernet0/17 description 4948-CORE1-FR # Gi1/0/9 switchport trunk encapsulation dot1q switchport mode trunk switchport nonegotiate channel-group 10 mode active end interface GigabitEthernet0/18 description 4948-CORE1-FR # Gi1/0/10 switchport trunk encapsulation dot1q switchport mode trunk switchport nonegotiate channel-group 10 mode active end interface Port-channel10 description 4948-CORE1-FR (Local : gi0/17-18 # Peer : Gi1/9-10) switchport trunk encapsulation dot1q switchport mode trunk switchport nonegotiate end Hope these examples can help you to find the correct design.
