Licensing Requirements and Limitations for RRPP

Other network elements are not required.

RRPP is a basic feature of a switch and is not under license control.

All models of S2720, S5700, and S6700 series switches support RRPP.

For details about software mappings, visit Hardware Query Tool and search for the desired product model.

Only the S5700-HI, S5710-EI, S5710-HI, S5720-EI, S5720-HI, S5730-HI, S5731-H, S5731S-H, S5732-H, S6700-EI, S6720-EI, S6720-HI, S6720S-EI, S6730S-H, and S6730-H support RRPP snooping.
When you configure the list of protected VLANs, note the following points:
- Protected VLANs must be configured before you configure an RRPP ring.
- You can delete or change existing protected VLANs before configuring an RRPP ring. The protected VLANs cannot be changed after the RRPP ring is configured.
- In the same physical topology, the control VLAN in a domain cannot be configured as a protected VLAN in another domain.
- The control VLAN must be included in the protected VLANs; otherwise, the RRPP ring cannot be configured.
- The control VLAN can be mapped to other instances before the RRPP ring is created. After the RRPP ring is created, the mapping cannot be changed unless you delete the RRPP ring.
- When the mapping between instances and VLANs changes, the protected VLANs in the RRPP domain also change.
- All the VLANs allowed by an RRPP interface must be configured as protected VLANs.
