ip forward-broadcast ACL

Hello,

 

I have a HPE 5510 switch which is comware 7 based.

I need “ip forward-broadcast”. So this isn’t hard to configure but in comware 5 it was possible to add an ACL to the “ip forward-broadcast”.

 

Acl 3001

rule 10 permit udp source 192.168.200.0 0.0.0.255 destination 10.0.0.255 0 destination-port eq 9

 

Comware 5: ip forward-broadcast acl 3001

Comware 7: ip forward-broadcast

 

So to have less broadcast forwarded how to add a acl to the “ip forward-broadcast”

Re: ip forward-broadcast ACL

Had the exact same question this morning:
You can just apply an acl to the interface with 'packet-filter 3001 outbound' (or inbound, depending of your network config).

 

Your ACL may be:

 

Acl 3001
  rule 10 permit udp source 192.168.200.0 0.0.0.255 destination 10.0.0.255 0 destination-port eq 9
  rule 15 deny ip destination 10.0.0.255 0
rule 20 permit ip

Hope this can help someone avoiding loosing time…

Re: ip forward-broadcast ACL

 

I am having the same problem. about packet-filter solution, doesn't it block all unicast and multicast traffic too along with broadcast?
