VGRP on SG500

Hi 

 

I  tried to use VGRP between two SG500-52. but VLAN is not automaticly created on the second switch Could you help me please  

The diagram of the network:

Stack-SG500 gi1/1/50 <-----------------------> gi1/49 SG500
VLAN 1
VLAN 115

 

Configuration 

 Stack-SG500

voice vlan oui-table add 00e0bb 3Com_phone______________
gvrp enable
bonjour interface range vlan 1
hostname Stack-SG500
ip ssh server

 

Stack-SG500#sh running-config interface gi1/1/50
interface gigabitethernet1/1/50
 gvrp enable
 switchport trunk allowed vlan add 115
!

 

On SG500

gvrp enable
hostname SG500
ip ssh server

 

interface gigabitethernet1/49
 gvrp enable
!

 

 

 

SG500#sh vlan
Created by: D-Default, S-Static, G-GVRP, R-Radius Assigned VLAN, V-Voic

Vlan       Name           Tagged Ports      UnTagged Ports      Created
---- ----------------- ------------------ ------------------ ----------
 1           1                             gi1/1-52,Po1-32          V

SG500#

 

Why the Vlan 115 is not Crreated ?

Thanks

Though, there are several

Though, there are several requirements, which should be fulfilled to make GVRP work:
Spreading VLANs switch

1. At least one port must be a member of the VLAN, which we want to spread to another switch 2. There must be a device connected to this port

3. The ports, that are connected to another switch must be in Trunk mode

4. VLANs, which we want to advertise, must be added as a Tagged traffic to this Trunk

5. The Port that belongs to a VLAN, which will be advertised, must be in mode GVRP Enable

6. If you want that a switch only advertises its VLANs, but not add VLANs learned from another switch, then you must specify the Dynamic VLAN Creation: Disable to the port that is connected to another switch

 

Receiving VLANs switch

7. The ports, that are connected to another switch must be in Trunk mode

8. If both switches are configured with Dynamic VLAN Creation: Enable, then each switch will add VLANs, advertised by another switch.
