Chapter 12 Configuring InterVLAN Routing
Configuring InterVLAN Routing on the MSFC
Autostate exclude mode affects all VLANs to which the port belongs and is supported on Ethernet, Fast
Ethernet, and Gigabit Ethernet ports only.
Note You cannot configure both autostate exclude mode and autostate track mode on the same port.
Autostate Track Mode
You can use autostate track mode to track key VLAN or port connections to the MSFC. When you
configure the autostate track mode, the SVI stays up if any tracked connections remain up in the VLAN.
Track mode requires that you define a global tracked VLAN group. The VLANs in this group will be
tracked by MSFC autostate whether or not you define a member port to be tracked.
When you configure a VLAN and the ports to be tracked by autostate, the tracked SVIs remain down
until at least one tracked Ethernet port in the VLAN moves to the Spanning Tree Protocol (STP)
forwarding state. Conversely, tracked SVIs remain up if at least one tracked Ethernet port stays in the
STP forwarding state.
Autostate track mode is supported on Ethernet, Fast Ethernet, and Gigabit Ethernet ports only.
Note You cannot configure both autostate exclude mode and autostate track mode on the same port.
Configuring Autostate Exclude Mode
To configure autostate exclude mode, perform one of these tasks in privileged mode:
This example shows how to exclude a port from MSFC autostate:
Console> (enable) set msfcautostate exclude 3/1
Port 3/1 configured as excluded port
Console> (enable)
This example shows how to clear the autostate configuration:
Console> (enable) clear msfcautostate 3/1
MSFC autostate config cleared on excluded port 3/1
Console> (enable)
Task Command
Configure autostate exclude mode. set msfcautostate exclude mod/port
Clear the autostate configuration. clear msfcautostate {all | mod/port}
