Cisco IOS 12.0 Switching Services

Restrictions on Using IP Router Commands with MLS Enabled

When you issue some Cisco IOS commands, you will affect Multilayer Switching on your router. The commands that will affect MLS are as follows:

• clear ip-route— Clears all MLS cache entries for all Catalyst 5000 series switches performing Layer 3 switching for this MLS-RP.

• ip routing— The no form purges all MLS cache entries and disables MLS on this MLS-RP.

• ip security (all forms of this command)— Disables MLS on the interface.

• ip tcp compression-connections— Disables MLS on the interface.

• ip tcp header-compression— Disables MLS on the interface.
