ERS 3524 Configure port with ip (routed interface)

known1 — Tue, 24 Nov 2020 22:38:15 GMT

We are installing a uCPE at one of our locations, and we are tasked with configuring a port with a specific IP for the uCPU to connect. I assumed that the ERS is a layer 3 switch. You can do this on cisco switched using the no switchport command. Is this possible on the ERS switches?

Essentially the uCPE will be (x.x.x.1 and the port on the ers would be x.x.x.2)

Hi,

It is not clear what you ask.

With the ERS you can always add an IP interface to a VLAN.

Ensure the ip forwarding is enabled:

I suppose I was trying to do it outside of the vlan. Like I said on cisco switch this would be referred to as a L3 “routed interface”.

“
The no switchport command puts the interface in L3 mode (known as "routed port") and makes it operate more like a router interface rather than a switch port. The ip address command assigns an IP address and network mask to the interface. Routed ports can be configured with a Layer 3 routing protocol.
However, restrictions apply:
It does not support VLAN subinterfaces.

It does not support Layer 2 protocols, such as DTP and STP.

It is supported only on switches running the IP base or IP services image.”

This is not available on ERS (IP on interface), I know it is available on VSP and called brouter.
