How to allocate physical interfaces to VDC in a Cisco Nexus 7000 Series switch?

Yasir Irfan Yasir Irfan Profile: Yasir Irfan


To allocate physical interfaces to VDC from the config terminal mode type the VDC name and then allocate the physical interfaces as shown below by using the command “allocate interface”

N7000-ITKE01#configure t

N7000-ITKE01 (config)#vdc VDC-CORE1

N7000-ITKE01-DC-CORE1 (config-vdc)#allocate interface  Ethernet1/1

N7000-ITKE01-DC-CORE1 (config-vdc)#allocate interface  Ethernet1/2

N7000-ITKE01 -DC-CORE1 (config-vdc)#allocate interface  Ethernet1/3

Now let’s verify the Interface allocation to the VDC by using following command ” show vdc membership”

N7000-ITKE01-DC-CORE1# show vdc membership

vdc_id:2 vdc_name: DC-CORE1 interfaces:
        Ethernet1/1           Ethernet1/2           Ethernet1/3          
        Ethernet1/4           Ethernet1/5           Ethernet1/6          
        Ethernet1/7           Ethernet1/8           Ethernet1/9          
        Ethernet1/10          Ethernet1/11          Ethernet1/12         
        Ethernet1/13          Ethernet1/14          Ethernet1/15         
        Ethernet1/16          Ethernet1/17          Ethernet1/18         
        Ethernet1/19          Ethernet1/20          Ethernet1/21         
        Ethernet1/22          Ethernet1/23          Ethernet1/24         
        Ethernet1/25          Ethernet1/27          Ethernet1/29         


In addition to interfaces other physical resources such as IPv4 router memory, IPv6 router memory, port-channels, SPAN sessions can be allocated to individual VDC.
