switching time of IP ERP have been improved to a bit less than 50 ms
The G.8032v2 ERP implementation has been enhanced to achieve sub-50ms ring protection switch time. This enhancement involves optimizations to reduce the number of MAC flushes, temporary flooding of traffic while MAC flush is in progress, and faster link failure detection using Connectivity Fault Management (CFM).
You will need to configure the following to achieve sub-50ms ring protection switch time.
Enter the following command to allow temporary flooding of traffic during MAC flush. Use the no version of this command to disable the flooding of traffic.
Brocade(config-erp-1)#flooding-enableSyntax: [no] flooding-enable
During topology change, there are multiple MAC flushes triggered by ERP protocol. Optimizations have been made to ERP protocol to reduce the number of MAC flushes to achieve faster convergence. These optimization can be enabled using the fdb-flush-optimization command. Use the no version of this command to disable the flush optimization.
Brocade(config-erp-1)#fdb-flush-optimizationSyntax: [no] fdb-flush-optimization
IEEE 802.1ag can be used to monitor the ERP interfaces for signal failures.The dot1ag-compliance command allows MD and MA’s configured as part of IEEE 802.1ag to be associated with an ERP instance. Use the no version of this command to disable the dot1ag-compliance command.
