Mr. Biel,
According to CCO,
http://www.cisco.com/univercd/cc/td/doc/pcat/ca4000.htm#xtocid58994,
the L3 module supports ISL on the uplink interfaces.
Those are GigabitEthernet 1 & 2 when configuring the
module.
Ex:
interface GigabitEthernet 1
no ip address
no ip directed-broadcast
no negotiation auto
!
interface GigabitEthernet 1.10
encapsulation isl 10 ! VLAN 10
bridge-group 10
!
interface GigabitEthernet 3
no ip address
no ip directed-broadcast
no negotiation auto
channel-group 1
!
interface GigabitEthernet 4
no ip address
no ip directed-broadcast
no negotiation auto
channel-group 1
!
interface Port-channel 1
no ip address
no ip directed-broadcast
no negotiation auto
!
interface Port-channel 1.10
encapsulation dot1q 10 ! VLAN 10
no ip address
no ip directed-broadcast
no negotiation auto
bridge-group 10
bridge 10 protocol ieee
