Hello!
I'm trying to configure GVRP between two SPS224G4 switches, but without success.
Switch A, port e24 is connected to Switch B, port e1
sw3# show run
interface ethernet e24
description sw4:e1
exit
interface range ethernet e(1,24)
switchport mode trunk
exit
vlan database
vlan 300,303
exit
interface range ethernet e(1,24)
switchport trunk allowed vlan add 300
exit
interface ethernet e2
switchport access vlan 303
exit
interface range ethernet e(1,24)
switchport trunk allowed vlan add 303
exit
interface vlan 300
name Management
exit
interface ethernet e24
gvrp enable
exit
gvrp enable
interface vlan 300
ip address 10.10.255.4 255.255.255.0
exit
ip default-gateway 10.10.255.1
hostname sw3
Switch B:
sw4# show run
interface range ethernet e(1,24)
switchport mode trunk
exit
interface ethernet e1
gvrp enable
exit
gvrp enable
hostname sw4
But vlans 300,303 configured on Switch A do not appear in VLAN table on switch B:
sw4# show vlan
Vlan Name Ports Type Authorization
---- ----------------- --------------------------- ------------ -------------
1 1 e(1-24),g(1-4),ch(1-8) other Required
Any suggestions? Thanks!

Hello,
In my opinion on SPS224G4 switches you need to configure following things for GVRP to work.
GVRP Enable on device
GVRP state on device (enabled/disabled)
Dynamic VLan creating enabled on interface
GVRP registration enabled on device.
See this doc, should help..

Dear Hitesh,
Thank you for the info... Do you have LinkSys switches with enabled GVRP in your network? :)
Before writing here I read a lot of docs regarding GVRP on LinkSys switches. After 8 hours of dancing around them I succeeded in getting them to work.
Now I see dybamic VLANs on switch B:
Vlan Name Ports Type Authorization
---- ----------------- --------------------------- ------------ -------------
1 1 e(1-24),g(1-4),ch(1-8) other Required
300 300 e1 dynamicGvrp Required
303 303 e1 dynamicGvrp Required
But I cannot add any port neither to vlan 300 nor to vlan 303!
sw4# conf t
sw4(config)# int eth e2
sw4(config-if)# switchport mode access
sw4(config-if)# switchport access vlan 300
VLAN 300: VLAN was not created by user.
My conclusion: the realization of GVRP in LinkSys switches is completely weird and broken. And now I really don't know what to do with ~45 LinkSys SPS224G4 switches in my network. You know, creating one VLAN on them by hands is somewhat difficult, isn't it?
Is there anything able to change my mind? Thanks in advance!

Hi,
I dont have any linksys switches in my network as of now but once upon a time i had Cabletron with GVRP which messed up my network when connected with Cisco switches with redundant links.
Can you please post the config of switches on which you are trying your hand, coz i can see that you have configured all ports on SW4 as trunk in first post and than you are trying to configure it as access.
Also confirm the mode you are running for GVRP ? make sure links between switches are 802.1q trunk.

Hello Hitesh,
I wish to describe the situation more clearly.
Scheme:
switch A:e24 ----- e1:Switch B
Trunk e24-e1 is 802.1Q. Linksys does not support another types.
Current configuration of switches:
Switch A:
-----------------------------------------------
sw_A# show run
interface range ethernet e(2-23)
shutdown
exit
interface ethernet e24
description sw4:e1
exit
interface range ethernet e(1,24)
switchport mode trunk
exit
vlan database
vlan 300,303
exit
interface range ethernet e(1,24)
switchport trunk allowed vlan add 300
exit
interface ethernet e2
switchport access vlan 303
exit
interface range ethernet e(1,24)
switchport trunk allowed vlan add 303
exit
interface vlan 300
name Management
exit
interface range ethernet e(1,24)
gvrp enable
exit
interface ethernet e1
gvrp vlan-creation-forbid
exit
gvrp enable
interface ethernet e1
gvrp registration-forbid
exit
interface vlan 300
ip address 10.10.255.4 255.255.255.0
exit
ip default-gateway 10.10.255.1
hostname sw_A
----------------------------------------------
Switch B:
----------------------------------------------
sw_B# show run
interface range ethernet e(3-24)
shutdown
exit
interface ethernet e1
switchport mode trunk
exit
interface ethernet e1
gvrp enable
exit
gvrp enable
hostname sw_B
-----------------------------------------------
On the switch B I see dynamic VLANs that it learned from switch A:
sw_B# show vlan
Vlan Name Ports Type Authorization
---- ----------------- --------------------------- ------------ -------------
1 1 e(1-24),g(1-4),ch(1-8) other Required
300 300 e1 dynamicGvrp Required
303 303 e1 dynamicGvrp Required
But when I'm trying to add a port on switch B to any of VLANs I get an error:
sw_B(config)# int eth e2
sw_B(config-if)# switchport mode access
sw_B(config-if)# switchport access vlan 300
VLAN 300: VLAN was not created by user.
Regarding the mode that I run for GVRP: I don't undestand what did yoy mean... :(
I haven't seen any modes for GVRP on linksys.
It is just enabled globally and enabled on trunk port:
sw_B# show gvrp configuration
GVRP Feature is currently Enabled on the device.
Maximum VLANs: 255
Port(s) GVRP-Status Registration Dynamic VLAN Timers(milliseconds)
Creation Join Leave Leave All
-------- ----------- ------------ ------------ ---- ----- ---------
e1 Enabled Normal Enabled 200 600 10000
e2 Disabled Normal Enabled 200 600 10000
e3 Disabled Normal Enabled 200 600 10000
e4 Disabled Normal Enabled 200 600 10000
e5 Disabled Normal Enabled 200 600 10000
...

Hi,
The config looks good to me. It seems that it is not allowing to manage the dynamically learned Vlan. I think there may be bug in the firmware that you are using.
See this topic, It could be helpful
http://forums.linksysbycisco.com/linksys/board/message?board.id=Switches&thread.id=3228
I ll Suggest you to confirm it from Linksys Support team.
