Cisco 2960s trunk to SG220-50

[4pratik]

I'm trying to use SG220-50 as access layer switch and estiblished a trunk connection from Catalyst 2960-s Switch to it. Issue I came across is not able to ping/access the MGMT IP on SG220-50. 

Please let me know if someone has established a connection from  Cisco 2960s trunk to SG220-50 and able to manage SG220-50.

From what source you are not able to ping ? from Switch or from the device ?

can you post the switch config, and let us know what is the IP address of SG220?

Please find the Configuration from 2960-S . I've attached screenshot from SG220-50

interface GigabitEthernetx/y/z
description Trunk to SG220P

switchport trunk allowed vlan 1,10,11,86,198

Please see attached screenshot from SG220-50

So Do you have VLAN 198 on Your Switch 2960 ? where is the Gateway IP configured 10.11.0.1?

Can you post 2960 Config ?

[4pratik]

Please find 2960S configs. 

gateway 10.11.0.1 is on our 3750 stack switch directly connected to 2960S.

[balaji.bandi]

Are you able to ping from 2960 console 10.11.0.1 and 10.11.0.X (SG220IP ?)

from SG  you able to ping 10.11.0.4?

[4pratik]

I’m able to Ping 10.11.0.1 from 2960 SW but not able to Ping SG IP 10.11.0.5.

SG-220 doesnt have console access so I am not able to check if SG is able to ping 10.11.0.4 or 10.11.0.1.

Hi,

Here is the mistake:

interface GigabitEthernet1/0/11
 description Trunk to  SG220-50 
 switchport trunk native vlan 86
 switchport trunk allowed vlan 1,10,11,86,198
switchport mode trunk
 switchport port-security aging type inactivity
 mls qos trust cos
 spanning-tree guard root

As your Cisco 2960s having Native VLAN 86 but SG220 is configured with Native VLAN 198. So here VLAN mismatch is an issue for you. 

Make it correct as:

interface GigabitEthernet1/0/11
description Trunk to SG220-50
switchport trunk native vlan 198
switchport trunk allowed vlan 1,10,11,86,198
switchport mode trunk
switchport port-security aging type inactivity
mls qos trust cos
spanning-tree guard root

Thank you for solution,

Just wanted to clarify that SG-220 has Management VLAN which is also a Native VLAN for the switch ? If so it is bit a separate config than legacy IOS devices.

Thanks and Regards,

Pratik

Thank you for solution, it did worked right away after changing the native VLAN id.

Boa noite

Estou com o mesmo problema, porém no meu caso a VLAN de gerenciamento é VLAN 100 e a VLAN native 1 (padrão), porém eu não tenho gerenciamento dos demais SWITCHs para do SW-CORE.
