- Want to deploy APIC-EM in our environment. It makes sense to deploy new device for remote site via mobile app, but how to connect the new device to existing system if we want to deploy the new equipment in the LAN using DHCP. Want to connect the new device to access port or routed port on existing switch.
- Solution Guide for Cisco Network Plug and According to instruction below It seems have to reconfigure our core switch and change the port from trunk to routed port so it can support PnP deployment for new device which is going to be up-linked to that port. It will be disaster to change all ports on core switch to routed port and configure sub-interface for each of them.
- Cisco Router Trunk/Access Port Configuration—Typical branch networks include routers and switches. One or more switches are connected to the WAN router and other endpoints like IP phones and access points connect to the
- switches. When a switch connects to an upstream router, the following deployment models are supported for Cisco
- Network Plug and Play:— Downstream switch is connected to the router using a switched port on the router. In this type of connection, the switched port on the router must be configured as an access port. The Cisco Network Plug and Play solution does not work for the switch if the switched port on the router is configured as a trunk port.
- — Downstream switch is connected to the router using a routed port on the router. In this case, the routed port cansupport multiple VLANs using sub-interfaces. During the Plug and Play process the switch would automaticallyconfigure its port as a trunk port. In a large branch scenario, it becomes necessary to carry multiple VLANs between the router and the downstream switch. To support this use case, the switch must be connected to a routed port.
No need to upstream switch to be a routed port. If VLAN 1 is enabled the switch should use that to get an IP address and start PnP. If you want to use a vlan other than vlan 1, you would need to use the "pnp startup-vlan xx" command on the core switch. You can use a trunk port as well as long as native vlan is 1 (you need CDP to pass through correctly)
