access list for ports can not block multicast ips
i have 10x brocade icx 6450 switches so i have a acl like as following :
Standard IP access list port5: 2 entries
permit host x.x.x.x
then i have applied it to a port switch which is connected to x.x.x.x and when i send tcp syn attack with random source i see all sources dropped at port level but sources like as 220.127.116.11 reach my router!
why does access list does not block multicast ips?! its really strange because i have deny any at end of my access list!
so can anyone help me with this?
