Could not assign vlan on EHWIC-D-8ESG

[miaozhixu]

Platform Cisco 1941, Interface Card EHWIC-D-8ESG

• int vlan 2
• ip address 192.168.2.1 255.255.255.0
• no shut

After these commands issued, I immediately configure the interface on EHWIC-D-8ESG,using the following commands.

• int G 0/1/0
• switchport access vlan 2

But, IOS replied that Could not found the access vlan, creating vlan 2.

And, show ip int bri shows that the vlan 2 is shutdown.

Any help will be appreciated.

Hi,

Could you please post the output of "show vlan brief " or " show vlan-switch brief ". Did you create a Layer 2 interface. Please issue the command " vlan 2 " under config mode as that would create a Layer 2 vlan in the vlan database.

conf t

vlan 2

exit

To define a VLAN, not only use interface vlan command to configure it, but also need a vlan command to create it first?

Hi Friend,

Debugging :- 

1) when interface vlan is showing shutdown then check if physical interface to which acces vlan is configured is up or not.

• int G 0/1/0  should be up state. 

now do no shut on interface vlan and check.

I just know that. I thought that vlan and ethernet interfaces are independent.

[lohit prasad]

Vlan depends upon your port status otherwise traffic will not be allowed.

yes

Yes, when the port status changed, it also change the vlan status, but it has a 2-3 seconds delay.

this message comes, when a vlan does not exit in database.
