I was able to test this on a M6220 and can confirm the behavior you are seeing is a hardware limitation. The IP based ACL cannot be applied Egress. You should have no problems applying Ingress. 
Hello, got a pair of PowerConnect M6220 blade switches, pretty much the same as 6224I am trying to apply acls to interface, and I am unable to do so. Here is what I am trying to do:coresw(config)#access-list internet-out deny ip any 10.0.0.0 255.0.0.0coresw(config)#access-list internet-out permit everycoresw(config-if-Gi1/0/17)#ip access-group internet-out outError processing ACL.coresw(config-if-Gi1/0/17)# <190> MAR 25 00:37:12 10.128.101.1-1 DRIVER[126512544]: broad_acl.c(1611) 4 %% ACL not applied to port 134217728 There are no other ACLs in this switch or on any interface on the switch.As you can see, this is a 2 line acl from the 90's which refuses to work. Basically what I am trying to do is filter out any local ip traffic.Am I doing something wrong here? According www.dell.com/.../pwcnt_IP_ACLs.pdf I can filter destination in egress. Any help is appreciated, thank you.
