Enter system view 

— 

Enable the device to receive 
directed broadcasts 

ip forward-broadcast 

Required 

By default, the switch is disabled 
from receiving directed broadcasts.

 

Follow these steps to enable the device to forward directed broadcasts: 

Enter system view 

system-view 

— 

Enter interface view 

interface interface-type 
interface-number 

— 

Enable the interface to forward 
directed broadcasts 

ip forward-broadcast [ acl 
acl-number ] 

Optional 

 

Currently, the ip forward-broadcast [ acl  acl-number ] command is not supported by the S7900E 

series Ethernet switches. By default, the devices allow forwarding of directed broadcasts to a directly 

connected network. 

 

As shown in

, 

the host’s interface and VLAN-interface 3 of Switch A are on the same network 

segment (1.1.1.0/24). VLAN-interface 2 of Switch A and VLAN-interface 2 of Switch B are on another 

network segment (2.2.2.0/24). The default gateway of the host is VLAN-interface 3 (IP address 

1.1.1.2/24) of Switch A. Configure a static route on Switch B to enable the reachability between host 

and Switch B. 

It is required that directed broadcasts from the host to IP address 2.2.2.255 be received by Switch B.
