148  SBC session border controllers 
 
Syntax 
[no] bridging to <interface> <range> 
Parameters 
<interface> — interface type: 
  cpu-port; 
  front-port — external uplink interfaces; 
  host-channel; 
  host-port; 
  port-channel — LAG uplink interface aggregation groups; 
  sm-port. 
<range> — number of the port/ports with which traffic exchange is allowed: 
  for cpu-port: <1/0>, where:  
  for front-port: <unit/port>, where:  
  unit — module number, may take value [1], 
  port — port number, may take values: [0 .. 3]; 
  for host-channel: [1]; 
  for host-port: 
  unit — module number, may take value [1], 
  port — port number, may take values: [0 .. 2]; 
  for port-channel: [0 .. 4]; 
  for sm-port: [0 .. 15]. 
  unit — module number, may take value [1], 
  port —  port number, may take values: [0 .. 5]. 
Example 
SBC2000-[CONFIG]-[SWITCH]-[if]> bridging to front-port all 
flow-control  
This command enables/disables the flow control mechanism on the interface to be configured. The flow control 
mechanism makes it possible to compensate for differences in transmitter and receiver speeds. If the traffic amount 
exceeds a  certain  level, the receiver  will  transmit frames informing  the  transmitter of the need  to reduce  the 
amount of traffic to reduce the number of lost packets. To implement this mechanism, it is necessary that the 
remote device also supports this function. 
Syntax 
flow-control <act> 
Parameters 
<act> — allocated action: 
  on — enable; 
  off — disable. 
Default value 
off
