I've got a Cisco 4503 Core Switch with two VLANs configured.
All is going OK with access lists management between the two VLANS, but now I have a scenario where I need to block only SQL traffic between two hosts on the same VLAN.
Is this supported?
To make it simple: I have two subnets 192.168.5.0 and 192.168.6.0 on VLANs 5 and 6 respectively.
VLAN 5 is defined on 8 physical ports of the switch and VLAN 6 on 4 physical ports of the switch.
I want to stop only SQL traffic between the two hosts 192.168.6.15 and 192.168.6.20 that are both on VLAN 6.
How can this be done on a Cisco 4503?
We configure mac based access-lists and implement it using an Access Map thus VLAN Access Maps are essentially used to filter Layer 2 information. It will not work in your case.
