Hello @KemalRzky_ ,


show run int gi0/0


show ip vrf


a possible explanation is that the interface is member of a VRF and so it cannot pinged normally you should ping vrf <vrf-name>

Some devices have a built in VRF named management and this can be your case as gi0/0 can be the management interface.


usually on switches the first user data port is something like gi0/1


Hope to help



Hi sir,


Thankyou for your answer..


I have checked the system and it shows:


#show run int gi0/0
Building configuration...

Current configuration : 175 bytes
interface GigabitEthernet0/0
vrf forwarding Mgmt-vrf
ip address
no ip redirects
no ip unreachables
no ip proxy-arp
negotiation auto


#sh ip vrf
Name Default RD Interfaces
Mgmt-vrf <not set> Gi0/0




What should i do next, if i still want to use Mgmnt Ethernet?

I'm sorry for this basic question '')

Hello @KemalRzky_ ,

move the configuration to another interface on the switch without the line

vrf forwarding Mgmt-vrf.

and adding the line

no switchport

! to be able to give an IP address to it

Gi0/0 is dedicated to management purposes and have some limitations give it a different IP address in a different IP subnet and do not use it for the moment.


Hope to help
