acl OUT on vlan interface not working

hi ..

i have L3 core switch with 5 no of vlan configured , with VTP mode server,

there 5 access switches connected to core with vtp client mode..

vlan 10 - 192.168.10.0/24 - management

vlan 20 - 192.168.20.0/24 - server

vlan 30 - 192.168.30.0/24 - data

vlan 40 - 192.168.40.0/24 - printer, other

vlan 50 - 192.168.50.0/24 - voice

 

all access switches are configured with management vlan 10 (192.168.10.x) 

here the requirement is , if any one telnet to these mgmt IP , should be blocked except few IP and this shall happen at core switch level, dont want to apply the acl in all access switch under vty.

 

so , the acl configured below

 

ip access-list extended FEW

5 permit ip 192.168.20.0 0.0.0.31 192.168.10.0 0.0.0.255

10 permit ip host 192.168.30.10 192.168.10.0 0.0.0.255

 

int vlan 10

ip add 192.168.10.1 255.255.255.0

ip access-group FEW out

 

---------------------------

but not getting the required result, all mentioned IP above able to telnet?? So what is the reason?? how to slove it?? Thanks in advance.

What type of switch is the core and is the management VLAN the only IP interface on the access switches?

Thanks

hi,

 

Its 4500, ..yes access switch configured with only one ip under vlan 10

 

Thanks

What type supervisor and version of code?

hi Thanks...

 

its 8L-E sup.. not sure about version.

Is there any issue with acl?? or do you think any bug issue?

I don't see a problem with the ACL so I wouldn't rule out the possibility of a bug.

How about adding deny any any to the end of the ACL, perhaps with the log extension just to see what that does.

is there any possibility ? like extra space in named acl , which leads to this issue??

i dont see hit also

Not likely, if the syntax is wrong it won't accept the command.

Thinking a bug or possibly something in the system architecture. A CCO Case may be in order.

I don't have any 8-LEs on my network but will be turning one up next week so I'm curious and will be able to investigate further. Post the version of IOS if you can.
