Unanswered Question

Hello Experts!

how to configure this Requirments:


VLAN Access Control

Configure an ACL with name “ACL-V” to obtain the following requirements:-

- Deny Web Traffic from 172.16.10.0/24 to Subnet 192.168.106.0

- Permit Web Traffic from 172.16.0.0/8 to Subnet 192.168.106.0

- Permit Any Other ip traffic from your POD to Subnet 192.168.106.0

Do not Use deny Statements, use only PERMIT statements.

(192.168.106.0 is VLAN_200)

You need to configure VLAN access-map to meet the mentioned requirements.


access-list 101 permit tcp 172.16.10.0 0.0.0.255 192.168.106.0 0.0.0.255 eq 80


access-list 102 permit tcp 172.16.0.0 0.0.255.255 192.168.106.0 0.0.0.255 eq 80


vlan access-map webtraffic seq 10

match ip address 101

action drop


vlan access-map webtraffic seq 20

match ip address 102

action forward


vlan filter webtraffic vlan-list 200


Please note I didnt create an acl for your 3rd statement bcoz I couldnt understand.


This should suffice your requirement of creating an acl with all permits statements & still denying traffic.


hope that clarifies.


pls rate all helpful posts.

HI

Permit Any Other ip traffic from your Rack to Subnet 192.168.106.0

any other Traffic to any where rather then the port 80

does this entry work:


ip access-list standard ALI

PERMit 172.16.0.0 0.0.255.255

vlan access-map filter 10

match ip address ALI

action drop

vlan access-map filter 20

match ip address ALI

action FW

vlan filter Filter vlan-list 199



Does it work?

Hi Ali,


I was bit confused with your ACL. You have matched same ACL in filter 10 and 20 and in filter 10 the action is DROP and in filter 20 the action is FWD for same ACL only. The check will work on first ACL and it will not come to second filter so the result will always be drop if source is 172.16.0.0/16


Can you please confirm once again what rules you are looking for?


Regards,


Ankur

This wouldn't accomplish what you need, since this map drops (denies) the traffic that you should allow through.

You need to drop only the /24 subnet, not the /16 one.
