Hi,

 

From different reason we can not use management vlan vlanID "1". Switch is connected to router with a one ethernet trunk dot1q, with more vlan inside. So I configured VLAN 160 - which is part of trunk, set IP address for Vlan 160. This ip address is reachable from router and it is working properly. 

 

interface gigabitEthernet 1/0/1

description "connection_to_router"
  speed 100
  switchport general allowed vlan 160,181,300 tagged
  no switchport general allowed vlan 1

 

interface vlan 160
  ip address 10.50.160.13 255.255.255.0
  description "mng"
  no ipv6 enable

 

///The next, an ethernet port is set ass access port with Vlan160 untag. 

 

interface gigabitEthernet 1/0/2
  switchport general allowed vlan 160 untagged
  no switchport general allowed vlan 1
 

///the isue is, after PC connection to interface gigabitEthernet 1/0/2,  PC is not able to ping 10.50.160.13.

 

In wireshark I see arp from PC, but switch does not answer. In case I check it with VLAN1 instead vlan 160 it is working without any problem.Did I forget to configure anything?

 

thanks a lot for your hints,

 

BR

In my opinion it should be:

 

interface gigabitEthernet 1/0/2

  switchport general allowed vlan 160 untagged

  switchport pvid 160

  no switchport general allowed vlan 1

Before you change the management VLAN, you need to confirm the port belongs to the new management VLAN.

 

The default PVID of all ports is 1, so we also need to change the PVID to 160 for the corresponding ports.

 Hi gys,

 

I tested it- Yes PVID and my misunderstanding what the PVID means was issue. It should be set in interface configuration.

 

thanks a lot for your support.

 

best regards
