Use the session mod_num command to access the Catalyst 4000 Layer 3 Services module prompt:
Step 2

Escape character is `^]'.
router>
a.
b.
Step 3 Assign an IP address and subnet mask (or IPX address) to the corresponding routed interface
(g3 and g4).
router(config)# interface g3
router(config-if)# ip address ip_address subnet_mask
router(config-if)# exit
router(config)# interface g4
router(config-if)# ip address ip_address subnet_mask
router(config-if)# exit
Autostate Feature
The autostate feature shuts down (or brings up) Catalyst 4000 Layer 3 Services module interfaces or
subinterfaces when the last external port on a VLAN goes down and when the first external port on the
VLAN is brought up.
When the last external port on a VLAN goes down, all Catalyst 4000 Layer 3 Services module interfaces
or subinterfaces on that VLAN are shut down by the autostate feature unless sc0 is on the VLAN or
there is another module in the chassis. If the other module in the chassis has an interface or subinterface
in the VLAN then the external port will stay up. When an Catalyst 4000 Layer 3 Services module
interface goes down, the following message is reported to the console for each Catalyst 4000 Layer 3
Services module interface:
When the first external port on the VLAN is brought back up, all Catalyst 4000 Layer 3 Services module
interfaces on that VLAN that were previously shut down are brought up. The following message is
reported to the console for each Catalyst 4000 Layer 3 Services module interface:
Use the show autostate entries command to see what Catalyst 4000 Layer 3 Services module interfaces
have been shut down or brought up by the autostate feature:
Router# show autostate entries
Port-channel1.5
Port-channel1.6
Port-channel1.4
