[c-nsp] Cisco blade switch config

For you information, here is what we did :

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)

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.
