Hello everyone,

 

I am trying to understand the new UI web interface of the TP2500G but seems inpredicteable.

 

 

I have a cisco G3650 who manage my internal network with 2 vlans (44 and 45). I would like to trunk it to my new T2500G in order to propagate my network and implement some security port on few access port. My C3650 has its own IP 10.10.0.10 and I would like to reach my new TP-Link though the same network 10.10.0.11.

 

 

On my cisco, I trunk the interface

interface GigabitEthernet1/0/7
 switchport trunk allowed vlan 44,45
 switchport mode trunk
end

 

resulting in

Port        Mode             Encapsulation  Status        Native vlan
Gi1/0/1    on               802.1q         not-trunking  1

 

 

But, on the TP-Link, it is another question. I did tag my 2 vlans on the interface 1/0/1 but if I change the IP of the switch, it become unreachable. I cannot see any configuration on the interface in order to it in trunk mode.

 

I did check the cli command but still, there is no many option there.

 

Did I config something wrongful ? I cannot clear my head with that.

 

Thank you for you help,

@AnthonyP, I suggest to temporarily add another access port to the VLAN you want to use for mgmt and to check the switch's connectivity after changing its IP address by connecting your laptop to this access port. It is always helpful to have a second (access) port for tests when changing the switch's IP.

 

Remember to save the new IP settings to make the change permanent. Then proceed to test the new IP setting over the trunk.

@R1D2 Thank for the hint.

 

For now, access ports are not working over DHCP. I managed to assign an IP to my VLAN directly from L3 Features -> Interface and I can reach it though the network. 

 

On my cisco switch, i get a nice response

Port        Mode             Encapsulation  Status        Native vlan
Gi1/0/1    on               802.1q         trunking      1

 

I have a separated DHCP Server. DHCP Server -> Cisco -> TP-Link. Shall I need to enable the DHCP L2 Relay. My guess would be either enable DHCP L2 Relay or DHCP Relay but as my client can ping the DHCP Server, i should not

@AnthonyP, don't use DHCP for assigning IPs to a switch or to a VLAN interface on a switch.

 

If your clients don't get an IP from DHCP, they cannot reach the server. Make sure clients are in the same broadcast domain or use DHCP relay if you have just one DHCP service running in another network.
