I have three Cisco SG300-28 switches. I setup a test lab environment with a core (server) switch in Layer 3 mode and the rest are (clients) in Layer 2 mode. As I understand, these switches doesn't support VTP, only GVRP. And GVRP works the same with VTP. Whenever you create VLANs on the core or main switch, other switches will learn from the core switch and no VLAN creation for the client switches will be made. (Hope I got it right. I guess GVRP is more complicated than VTP).
GOAL: Obviously, I want to use GVRP to create VLANs on the main switch so that I won't be doing it all over on the other switches.
The following is my (so far) configuration through CLI only:
I haven't use the web GUI. My SW version is 18.104.22.168.
1. I already enabled the GVRP globally.
2. I configured GE 12 & GE 24 as TRUNK ports for the core switch that connects both switches, I also configured GE 12 ports for both the client switches. All other ports are in ACCESS mode. (I am connected to GE 2 port)
3. I enabled GVRP on the TRUNK ports only for all switches.
4. I allowed all vlans on the TRUNK ports. (#switchport trunk allowed vlan add all)
5. All TRUNK ports registration mode is NORMAL and dynamic vlan creation is enabled on all trunk and access ports.
6. I created 3 VLANs without configuring its IP Addresses:
vlan 2 = MGT
vlan 3 = IT
vlan 4 = MKTG
I don't know if I missed something on the configuration or the connection. I was expecting the vlans I created will be learned from other switches. Hope somebody can help me out. Thanks a lot.
1. Is it necessary to enable all switches to layer 3 mode? Or depends on the network setup? Does this affect the GVRP?
2. Does switching ports to TRUNK mode means they are already 802.1q ports by default? Because I can't configure TRUNK ports to 802.1q (#switchport encapsulation dot1q) config like other switches.
I created the VLANs manually on each swtich and everything is working fine now. But I configured the IP addresses of each of the VLANs on my core switch only. I can ping now the VLAN's ip from client switches and from any computer that is a member of a VLAN. I'm still don't know how GVRP function as defined.
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
