ACE 4710 MAC Address

santipongv — Wed, 30 Apr 2008 14:56:49 GMT

All physical interfaces on ACE 4710 share the same MAC address. Also, VIP addresses share the same MAC address. ACE 4710 is connected to a switch. How is the switch supposed to know which interface to send the packet to if it is doing layer2 switching.

Thank you in advance for the explanation.

You can't put 2 interfaces in the same vlan

switch/Admin(config-if)# switchport access vlan 20

vlan 20 is associated with GigabitEthernet 1/3.

switch/Admin(config-if)#

So, the L2 switch will have an entry for the mac-address in each vlan and this entry can point to different interfaces.

All three interfaces are in different VLAN. How will packet know which interface to send the packet to, though, since they all have the same MAC address.

Answer is in your question.

Since all interface belong to different VLANs, all interfaces using same MAC doesnt matter.

For Incoming traffic Different Vlan Members will arp for diff addresses and will end up to ACE.

For outgoing traffic your routes will decide the outgoing ports.
