Dell OS S4148F Error: Interface is not in default mode

I tried associating an VLAN interface to the non-default VRF that you created, however, the configuration failed with % Error: Interface is not in default mode

# show ip vrf public_cust
VRF-Name Interfaces
public_cust

# show vlan 4001

Codes: * - Default VLAN, M - Management VLAN, R - Remote Port Mirroring VLANs,
@ - Attached to Virtual Network, P - Primary, C - Community, I - Isolated
Q: A - Access (Untagged), T - Tagged
NUM Status Description Q Ports
4001 Active T Eth1/1/50

# show running-configuration interface vlan 4001

interface vlan4001
mode L3
shutdown
mtu 9216
ip address 169.254.255.253/31

no ipv6 mld snooping

# configure terminal
(config)# interface vlan 4001
(conf-if-vl-4001)# ip vrf forwarding public_cust
% Error: Interface is not in default mode

I couldn't find any information regarding this error and what it means. Any help will be appreciated.

Hello,

 

I'm not sure which operating system you have, but I'm sharing some information for OS 10.4.3.0 as follows. OS version differences may affect the non-default VRF numbers you can create. For example, OS 10.4.1.0 version allows 16 non-default VRF instances, while OS 10.4.3.0 allows 128 non-default VRF instances. The rest will be the same. 

non-default VRF instances configure on page 388. https://dell.to/36jDwTH

 

You can reassign any interface assigned to a non-default VRF instance back to the default VRF instance.

Create a non-default VRF instance by specifying a name and enter VRF configuration mode. CONFIGURATION  ip vrf  vrf-name
 
After creating a non-default VRF instance you can associate a n interface to the VRF instance that you created.

To assign an interface to a non-default VRF, perform the following steps:

  1. Enter the interface that you want to assign to a non-default VRF instance. CONFIGURATION interface ethernet 1/1/1
  2. Remove the interfacet from L2 switching. INTERFACE no switchport
  3. Assign the interface to a non-default VRF. INTERFACE CONFIGURATION ip vrf forwarding vrf-test Before assigning a n interface to a VRF instance, ensure that no IP address is configured on the interface.
     

    NOTE: In the default configuration, the interface is in L3 mode and it does not have an IP address. You can associate an interface in L3 mode and with default configuration to a VRF. You can associate an interface only with one VRF instance. Overwriting associations between interfaces and VRFs is not allowed, until all the interface configurations including the previous VRF associations are deleted.
  4. Assign an IPv4 address to the interface. INTERFACE CONFIGURATION ip address 
  5. Assign an IPv6 address to the interface. INTERFACE CONFIGURATION ipv6 address 1::1/64 You can also auto configure an IPv6 address using the ipv6 address autoconfig command.


    • NOTE: Before configuring any routing protocol in a VRF instance, you need to first assign an IP address to at least one of the interfaces assigned to the VRF instance on which you want to configure routing protocols.

 

Let us know if this helps!

Hi Erman,

My switches are upgraded to OS 10.5.2.2 and I also read the configuration instructions quite carefully, and found no missing points compared to the instructions.

# show version

management
public_cust


I just created only one non-default VRF that the VLAN interface is assigned to.

(config)# interface vlan 4000
(conf-if-vl-4000)# ip vrf forwarding public_cust

% Error: Interface is not in default mode


Thanks for your information sharing and hope to get some help with this case.

Is there any other configuration on the port that it needs or can you set it back to default?
