what is the difference between GVRP and VCMP? both are use for vlan propagation?? Which one is best?

Error: The VLAN is a dynamic VLAN and cannot be configured.... error on esnp

i have configure GVRP on all the interfacesl trunk links

after configuring this 

port link-type access
 port default vlan 5
 i have received the following error

Error: The VLAN is a dynamic VLAN and cannot be configured....

Registration can be achieved either statically or dynamically for a VLAN within the device. A manually configured VLAN is a static VLAN, and a VLAN created through GVRP is a dynamic VLAN. They way in which registration is performed is dependant on the registration mode that has been configured. There are three registration modes that can be set, which includes normal, fixed and forbidden registration modes.

In the normal registration mode, the GVRP interface can dynamically register and deregister VLANs, and transmit both dynamic VLAN registration information and static VLAN registration information.

In the fixed mode, the GVRP interface is restricted from dynamically registering and deregistering VLANs and can transmit only the static registration information. If the registration mode of a trunk interface is set to fixed, the interface allows only the manually configured VLANs to pass, even if it is configured to allow all VLANs to pass.

In the forbidden mode, the GVRP interface is disabled from dynamically registering nd deregistering VLANs and can transmit only information about VLAN 1. If the registration mode of a trunk interface is set to forbidden, the interface allows only VLAN 1 to pass even if it is configured to allow all VLANs to pass.

We can assign a port to static VLAN.. if we want to assign a port to dynamic VLAN... we will get the following error...

Error: The VLAN is a dynamic VLAN and cannot be configured..

We have to creat static VLAN on LSW1 and LSW4.....remaining switches LSW2 and LSW3 will create dynamic vlan  

Configuration on four switches

LSW1

vlan batch 2 to 20
gvrp
interface GigabitEthernet0/0/1
 port link-type trunk
 port trunk allow-pass vlan 2 to 4094
 gvrp
interface GigabitEthernet0/0/3
 port link-type access
 port default vlan 2

LSW2

gvrp

interface GigabitEthernet0/0/1
 port link-type trunk
 port trunk allow-pass vlan 2 to 4094
 gvrp
#
interface GigabitEthernet0/0/2
 port link-type trunk
 port trunk allow-pass vlan 2 to 4094
 gvrp

LSW3

gvrp

interface GigabitEthernet0/0/1
 port link-type trunk
 port trunk allow-pass vlan 2 to 4094
 gvrp
#
interface GigabitEthernet0/0/2
 port link-type trunk
 port trunk allow-pass vlan 2 to 4094
 gvrp

LSW4

vlan batch 2 to 20
#
gvrp
interface GigabitEthernet0/0/1
 port link-type trunk
 port trunk allow-pass vlan 2 to 4094
 gvrp
#
interface GigabitEthernet0/0/2
 port link-type access
 port default vlan 2

CISCO VTP  and HUAWEI VCMP.

VTP 

VTP is a communication protocol running at the data link layer (Layer 2) of the OSI model
and manages the VLAN creation, deletion, and modification in a domain. When a VLAN is
configured on a VTP server, the VTP server automatically advertises the VLAN configuration
to other switches in the local domain. After receiving the VLAN configuration, the switches
modify their VLAN configurations to the same as that on the VTP server. This reduces the
VLAN configuration workload while retaining consistent VLAN configuration.
A VTP server sends Inter-Switch Link (ISL) frames or Cisco proprietary Dynamic Trunking
Protocol (DTP) frames to advertise the VLAN creation, deletion, and modification to other
switches in the local domain. VTP clients can automatically learn VLAN configurations,
making management convenient.
VTP supports three working modes: VTP server, VTP client, and VTP transparent. By default,
a switch is configured with VLAN 1 and the VTP server working mode before delivery. A
VTP domain can have only one VTP server.
 1 On a VTP server, you can maintain all VLAN lists in the local VTP domain and create,
delete, and modify VLANs.
2  A VTP client learns VLAN configurations from the VTP server and maintains all VLAN
lists, but you cannot create, delete, or modify VLANs on the client.
3  A VTP transparent switch is an independent switch that does not participate in VTP
implementation or learn VLAN configurations from the VTP server. On the VTP
transparent switch, you can create, delete, and modify only the local VLANs.

VCMP


VLAN Central Management Protocol (VCMP) is a Huawei proprietary protocol that supports

the configuration, management, and delivery of VLANs on a VCMP server. A VCMP domain
is composed of switches that have the same VCMP domain name and are connected through
trunk ports. A switch belongs to only one VCMP domain. Switches in a VCMP domain are
managed by the VCMP server in the local domain. The VCMP domain allows one VCMP
server and multiple VCMP clients. Attributes of the devices in the VCMP domain depend on
their roles, including:
 Server: A VCMP server synchronizes VLAN configurations to other switches in the local
domain.
 Client: A VCMP client synchronizes VLAN configurations from the VCMP server.
Transparent: A VCMP transparent switch neither affects other switches in the local
VCMP domain nor is affected by management behaviors. The VCMP transparent switch
forwards received frames through trunk ports.
Silent: Deployed at the edge of a VCMP domain, a VCMP silent switch neither affects
other switches in the local VCMP domain nor is affected by management behaviors. The
VCMP silent switch discards received VCMP frames.

gngogh Post On 2015-02-25 06:32


It seems not

[D1]vcmp role server
    ^
Error: Unrecognized command found at '^' position.
[D1]
[D1]display vcmp status
            ^
Error: Unrecognized command found at '^' position


Can someone confirm that vcmp is not working in eNSP or give us a hint how to make it work?
