A routed port is a physical port that acts like a port on a router. It does not have to be connected to a router. A routed port is not associated with a particular VLAN, as is an access port. A routed port behaves like a regular router interface, except that it does not support VLAN sub-interfaces. Routed ports can be configured with an L3 routing protocol.
When trying to configure an IP address on a sub-interface of a switch, this message may be displayed:
% Configuring IP routing on a LAN subinterface is only allowed if that sub-interface is already configured as part of an IEEE 802.10, IEEE 802.1Q, or ISL vLAN.
There is no option to configure the encapsultation on the sub-interface.
By default, the Catalyst 3750 or 3550 is a switch performing L2 functions and has L3 unicast routing disabled. You can enable this function by issuing the ip routingglobal command.
If you want to convert any port to a L3 port, issue the no switchportcommand.
Do not configure Ethernet sub-interfaces on a switch. Configure it as a trunk, and terminate the L3 IP interface on a Switched Virtual Interface (SVI).
All the features that are normally found on the Catalyst 3750 and 3550 are not available on the switch. That is, there are certain unsupported features on this platform. These features are not supported:
Configuring an IP address on a sub-interface of a switch
Configuring the encapsulation on the sub-interface
We recently upgraded our internet services from 100MB to 500MB. We manage the router for this connection and currently have a Cisco 2911 router for connectivity and we are unable to get more than 160MB throughput. We are wondering if we can get more out o...
Hello folks, I've got an issue with a new Catalyst 9300 deployment for a customer. We've moved routing from a dedicated router to the 9300 and the 9300 has taken the QoS for the site. We're using standard Auto QoS, trusting DSCP, but I'm ...

Actually I'm so confused about the diameter in STP , As i read in book (upper attached picture) we count diameter from the root bridge. But as i read here on the cisco website(Second attached picture) , we start counting from any to any of the ...
