Dear Support,
I have a Cisco SG300 and Cisco 3560 switches.
3560 is my Core Switch and SG300 is access switch.
From 3560 VLAN information is not passed to SG300.
3560 Configuration:
interface GigabitEthernet0/23
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1,2,10,11
switchport mode trunk
SG300 Configuration:
interface gigabitethernet49
spanning-tree link-type point-to-point
switchport mode general
switchport general allowed vlan add 2,10-11 tagged
macro description switch
Please suggest how this issue is resolve.
Regards,
JItesh Mahajan.

Hi Jlitesh,
First of all please note Small Business switches are not supporting VTP but I guess you have noticed this since SG300 trunk is configured manually.
Secondly your VLAN 1 is tagged on Catalyst while it is untagged (native) on SG300.
I would recommend you to remove VLAN 1 tagged from catalyst and add "switchport trunk native VLAN 1".
I hope this helps.

Hi Jltesh,
Please find below related commands:
catalyst(config)#interface gi0/23
catalyst(config-if)#switchport trunk allowed vlan remove vlan 1
catalyst(config-if)#switchport trunk native vlan 1
If you still have some problems on this trunk it would be worth checking mac address table for this port on each switch:
show mac address-table interfaces GigabitEthernet0/23 (or 49 when on SG300).

Hi Jltesh,
I think the best way to verify this is to get the following command:
Catalyst: show interfaces trunk
SG300: show vlan
also show MAC address table interface [ge49 or ge0/23] to verify the operational status

Aleksandra
