8212zl ACL Problem
We have a 8212zl connected to multiple 2910zl network switches. We use the 8212zl as our core switch to perform all routing. When I try to apply a ACL (access control list) on the 8212zl VLAN 226 to block all traffic except from iteself and VLAN 213, none of the traffic will block. Here is an example of the ACL:
ip access-list standard "VLAN226IN"
5 permit 172.20.213.0 0.0.0.255
10 permit 172.20.226.0 0.0.0.255
15 deny 0.0.0.0 255.255.255.255
exit
The VLAN has the following configuration:
vlan 226
name "VLAN226"
tagged A5,Trk1
ip access-group "VLAN226IN" in
ip access-group "VLAN226IN" out
ip access-group "VLAN226IN" vlan
ip address 172.20.226.1 255.255.255.0
ip igmp
ip rip 172.20.226.1
exit
Does anyone have any ideas on what is happening?
P.S. This thread has been moved from Switches, Hubs, Modems (Legacy ITRC forum) to ProCurve / ProVision-Based. - Hp Forum Moderator

Re: 8212zl ACL Problem
I htink you should have:
ip access-list standard "VLAN226IN"
5 permit 172.20.213.0 0.0.0.255 172.20.226.0 0.0.0.255
15 deny 0.0.0.0 255.255.255.255 0.0.0.0 255.255.255.255
ip access-list standard "VLAN226OUT"
10 permit 172.20.226.0 0.0.0.255 0.0.0.0 255.255.255.255
15 deny 0.0.0.0 255.255.255.255 0.0.0.0 255.255.255.255
name "VLAN226"
ip access-group "VLAN226IN" out
ip access-group "VLAN226OUT" in

Re: 8212zl ACL Problem
Here is what I currently have. All my other VLAN's can still talk to this VLAN for some reason. I also tried applying VLAN226IN to in and VLAN226OUT to out and that did nothing as well.
p access-list extended "VLAN226IN"
5 permit ip 172.20.20.13 0.0.0.255 172.20.226.0 0.0.0.255
15 deny ip 0.0.0.0 255.255.255.255 0.0.0.0 255.255.255.255
exit
ip access-list extended "VLAN226OUT"
10 permit ip 172.20.226.0 0.0.0.255 0.0.0.0 255.255.255.255
15 deny ip 0.0.0.0 255.255.255.255 0.0.0.0 255.255.255.255
exit
vlan 226
name "VLAN226"
tagged A5,Trk1
ip access-group "VLAN226OUT" in
ip access-group "VLAN226IN" out
ip address 172.20.226.1 255.255.255.0
ip igmp
ip rip 172.20.226.1

Re: 8212zl ACL Problem
Do a traceroute. I wonder if your inter-VLAN routing has happened somewhere else?

Re: 8212zl ACL Problem
.1 is presumably the address on the core switch. How about tracerouting to something further in the .226 network?
