I need to pass only traffic of IP, ARP and PPPoE protocols via Catalyst.
I've created the following configuration:
vlan access-map vmap1 10
action forward
match ip address ip1
vlan access-map vmap1 20
action forward
match mac address arp
vlan access-map vmap1 25
action forward
match mac address pppoe
vlan access-map vmap1 30
action forward
match mac address mac1
!
mac access-list extended arp
permit any any 0x806 0x0
mac access-list extended mac1
permit host 0000.0000.0001 host 0000.0000.0001
mac access-list extended pppoe
permit any any 0x8863 0x0
permit any any 0x8864 0x0
!
ip access-list extended ip1
permit ip any any
!
vlan filter vmap1 vlan-list 8
I'd applied this configuration to two Catalysts - 3550-24 and 3550-12G,
(both running IOS c3550-i5q3l2-mz.121-9.EA1c), and 3550-24 works fine !
However 3550-12G drops packets not only for filtered VLAN 8, but
for all others too, such slows down the whole traffic a lot, so I had to
disable filtering at all.
What should I do to solve this problem ?

If both of the switches are configured with this and only the 3550-12G is having the issues I would think that it is possibly an issue with the IOS and you probably need to go through the Bug Tool Kit and check your IOS/CAT OS.

The IOS versions on both switches are the same !
