Hi there,
At the moment I am experiencing some issues considering ACL's on ve
interfaces. Especially ve interfaces where the vlan has more then 1
port.
Sometimes the ACL will filter traffic that is NOT inside the vlan, but
does flow over one of the two ports that are in the vlan. As we have
more then 1 vlan tagged on these ports, the traffic involved is from
another vlan. For example:
Port 1: VLAN 5, VLAN 20, VLAN 30
Port 2: VLAN 5, VLAN 40, VLAN 31
If traffic from VLAN 20 goes to VLAN 31 (thus passing over both ports)
sometimes traffic gets ACL'd away. We see this because a logging
statement on VLAN 5.
Anyone else seen this ?
