Creating an RRPP Domain and the Control VLAN
Context
A group of interconnected switches configured with the same domain ID and control VLAN constitute an RRPP domain. Different RRPP domains must be configured with different domain IDs and control VLANs.
An RRPP domain has two control VLANs, that is, the major control VLAN and sub-control VLAN. Protocol packets on the major ring are transmitted in the major control VLAN, and RRPP packets on the sub-rings are transmitted in the sub-control VLAN.
Procedure
- On each switch in an RRPP domain, run system-view
The system view is displayed.
- Run rrpp domain domain-id
An RRPP domain is created and the RRPP domain view is displayed.
A maximum of 24 domains can be created on the S5720-EI, S5720-HI, S5720I-SI, S5720S-SI, S5720-SI, S5730-HI, S5730S-EI, S5730-SI, S5731-H, S5731-S, S5731S-H, S5731S-S, S5732-H, S6720-EI, S6720-HI, S6720-LI, S6720S-EI, S6720S-LI, S6720S-SI, S6720-SI, S6730-H, S6730S-H, S6730-S, and S6730S-S. A maximum of 16 domains can be created on the S5735-S, S5735-S-I, and S5735S-S. On other devices, a maximum of 8 domains can be created.
When creating an RRPP domain, specify the domain ID. If the domain to be configured exists, the domain view is displayed.
- (Optional) Run description text
A description is configured for the RRPP domain.
By default, no description is configured for an RRPP domain.
After RRPP is configured on a device, you can run the description command to configure the description of the RRPP domain, including the RPPP domain ID, to facilitate maintenance.
- Run control-vlan vlan-id
A control VLAN is created.
An RRPP domain has two control VLANs, that is, the major control VLAN and sub-control VLAN. You need to specify only the major control VLAN. The VLAN whose ID is one greater than the ID of the major control VLAN becomes the sub-control VLAN.
The control VLAN specified by vlan-id and the sub-control VLAN specified by vlan-id plus one must be VLANs that have not been created or used.
After configuring a control VLAN for an RRPP domain, you cannot directly change the control VLAN. To change the control VLAN, you need to delete the domain and then configure a new control VLAN. You can also run the undo control-vlan command to delete the control VLAN and then configure a new control VLAN. The sub-control VLAN is deleted when the RRPP domain is deleted.
DHCP services cannot be configured for control VLANs.
Do not run the mac-limit command in the control VLAN view to configure a MAC address limiting rule.
VLAN 1 is the default VLAN and cannot be configured as the control VLAN.
