74 CHAPTER 2: CUDA 12000 BASE SYSTEM COMMANDS
bridge-timeout
Configures aging and reply timers for bridge group broadcast flows.
Mode
To configure timers for all bridge groups on all interfaces:
root
To configure timers for a specific bridge group:
interface:bridge-group(<group>)
To configure timers for a specific interface:
interface:cable:csi(<c/s/i>)
Syntax
bridge-timeout {aging <number> | reply <number>}
Arguments
aging <number> Specifies the number of minutes to wait before timing out broadcast
flows that are idle or are associated with unreachable destinations. Values
range from 10 to 20. The default is 10.
reply <number> Specifies the number of seconds that the Cuda 12000 waits for a
broadcast flow reply to its broadcast flow request before removing the
broadcast flow. Values range from 2 to 10. The default is 2.
Cuda 12000 switches issue broadcast flow requests to find a destination
for an unknown packet. To verify that the destination is still reachable, the
Cuda sends this packet to every egress port that belongs to the same
bridge group or to one egress port.
In response to broadcast flow requests, the module that has the egress
port associated with the final destination IP address issues a broadcast
flow reply.
