Description This command configures the G.8032 fast-flood feature. When this command is executed, it
is stored in the configuration file after admin save is executed. A system reboot is required
for this command to take effect.
It is recommended to enable this command to improve service failover time due to failures in
the ring path. When fast flood is enabled, on failure detection in one of the paths of the ETH-
ring, along with MAC flush, the system starts to flood the traffic on-to the available path.
If this command is present in the configuration file, on reboot, the system allocates resources
for G.8032, by reducing the amount of resources available for use with ACLs. When this
command is used, G.8032 fastflood needs an entire chunk with "512" entries, therefore the
amount of resources available for use with ACLs is reduced by "512". The user needs to free
up resources used by ACLs and make them available for use by G.8032, before enabling this
command. The user should ensure that the resource usage of ACLs has been appropriately
modified before reboot, to make way for use of this feature. The user can free up resources
by either disabling the use of ACLs with a SAP or deleting a SAP, so that an entire chunk of
512 entries is available.
Before enabling the g8032-fast-flood-enable command, the user must check if sufficient
resources are available. The tools dump system-resources command is available to check
if sufficient resources are available. The 'Ingress Shared CAM Entries' field, shown in the
output below tools dump system resources command, must be more than or equal to 512
(the 'Free' column in the following output).
| Total | Allocated | Free
-------------------------------+-----------+-----------+------------
Ingress Shared CAM Entries | 0 | 0 | 512
The no form of this command removes the allocated resources for use by G.8032.The entire
resource pool is available for use by ACLs. The no form of this command takes affect only
on reboot.
