Venkatesh - I believe that you will need to use a vlan filter, if you
want to filter this traffic within the vlan.

Subject: ACL on SVI

Hi Guys,

I got confused with applying ACL on to a SVI, say if I have two switches
say
A and B and there is trunk that permits vlan 100 between them, andl each
of
the switch has a SVI for this VLAN say switch A's SVI ip address is
10.0.0.1/24 and switch B SVI's IP address is 10.0.0.2/24. added to this
is
switch A connects to the rest of the network. If I want to filter
traffic
from some hosts on vlan 100 on switch B to a specific destination in the
network, is it appropriate for me to apply an extended ACL's on switch
B's
SVI with outward direction ?

The reason for this confusion is with Physical or logical interface it
is
easy to say inside and outside in reference to router CPU but with a SVI
the
inside/outside can be seen in two different ways...

any help is appreciated

Thank you,
venkatesh
