SG350 tagged vlans to HPE Comware

[tdymek]

I have a problem connecting the SG350 to a HP Comware switch (A5800).

I have quite few SG300 switches and they work OK when connected to the HPE A5800. Recently I've got a new SG350 and trunk port configuration doesn't work. Port on HP switch is configured like this: vlan 1 untagged (native), vlan 160 tagged On sg350 I've configured a trunk port with tagged vlan 160. When I connect SG300 with the same port configuration I can see incomming mac addresses on both native and tagged vlana, nn SG350 I see incomming mac addresses only in default vlan

Port config on A5800:

interface GigabitEthernet2/0/40
 port link-mode bridge
 port link-type trunk
 port trunk permit vlan 1 160
#

Port config on SG300 (uplink to a5800, works):

interface gigabitethernet50
 switchport trunk allowed vlan add 160

Port config on SG350 (uplink to a5800, doesn't work) :

interface gigabitethernet50
 switchport trunk allowed vlan add 160

Any hints?

Hello tdymek,

The trunk ports on the SG350 series switches are being configured a bit different than on the SG300 switches. Please, try with the lines below:

interface gigabitethernet50

switchport mode trunk

switchport trunk allowed vlan remove 1-159,161-4094

These will add VLAN160 as tagged, by default VLAN1 is untagged. If you need to change the untagged VLAN, let's say to VLAN10, you can add the following command to the configuration above :

switchport trunk native vlan 10.

Hope this helps,
