Concept Explanation
There is no periodic transmission of TCRHFs. The TCRHFs are sent on triggered
events of ring failure or ring restoration only.
Implementing FRRP
• FRRP is media and speed independent.
• FRRP is a Dell proprietary protocol that does not interoperate with any other vendor.
• You must disable the spanning tree protocol (STP) on both the Primary and Secondary interfaces
before you can enable FRRP.
• All ring ports must be Layer 2 ports. This is required for both Master and Transit nodes.
• A VLAN configured as a control VLAN for a ring cannot be configured as a control or member VLAN
for any other ring.
• The control VLAN is not used to carry any data traffic; it carries only RHFs.
• The control VLAN cannot have members that are not ring ports.
• If multiple rings share one or more member VLANs, they cannot share any links between them.
• Member VLANs across multiple rings are not supported in Master nodes.
• Each ring has only one Master node; all others are transit nodes.
FRRP Configuration
These are the tasks to configure FRRP.
• Creating the FRRP Group
• Configuring the Control VLAN
– Configure Primary and Secondary ports
• Configuring and Adding the Member VLANs
– Configure Primary and Secondary ports
Other FRRP related commands are:
• Clearing the FRRP Counters
• Viewing the FRRP Configuration
• Viewing the FRRP Information
Creating the FRRP Group
Create the FRRP group on each switch in the ring.
To create the FRRP group, use the command.
• Create the FRRP group with this Ring ID.
CONFIGURATION mode
protocol frrp ring-id
Ring ID: the range is from 1 to 255.
