Catalyst 6500 Series Switch Command Reference—Release 8.4
OL-6244-01
Chapter 2 Catalyst 6500 Series Switch and ROM Monitor Commands
set msfcautostate
set msfcautostate
To enable or disable the line protocol state determination of the Multilayer Switch Feature Cards
(MSFCs) due to port state changes, use the set msfcautostate command.
set msfcautostate {enable | disable}
set msfcautostate {exclude | track} mod/ports
set msfcautostate track {enable | disable} vlan_list
Syntax Description
Defaults The default is enabled.
Command Types Switch command.
Command Modes Privileged.
Usage Guidelines This feature is used to accurately reflect the Layer 3 interface status based on the underlying Layer 2
interface status so that routing and other protocols converge faster. Faster protocol convergence prevents
traffic from being discarded without notice.
When you enable the MSFC auto state feature, VLAN interfaces on the MSFC are active only when there
is at least one other active interface in the spanning tree forwarding state on the Catalyst 6500 series
switch. This interface could be a physical end-user port, a trunk connection for which the VLAN is
active, or even another MSFC with an equivalent VLAN interface.
If you enable and then disable or disable and then enable the set msfcautostate command, you might
have to use the shutdown and no shutdown commands to disable and then restart the VLAN and WAN
interfaces on the MSFC.
If your FXS module ports are in an auxiliary VLAN and there are no switching module ports active in
the VLAN, the FXS module will not initialize because the MSFC auto state feature shuts down all MSFC
interfaces and subinterfaces. We recommend that you add a physical Ethernet port to the VLAN.
enable Activates the line protocol state determination.
disable Deactivates the line protocol state determination.
exclude Excludes ports from autostate.
track Tracks ports for autostate.
mod/ports Module number and port numbers.
enable Enables autostate tracking on a VLAN or VLANs.
disable Disable autostate tracking on a VLAN or VLANs.
vlan_list VLAN numbers; valid values are from 1 to 4094.
