Ethernet handoff

Hi can anyone explain what is ethernet handoff?

Re: Ethernet handoff

Is the feed provided to you by the carrier (ISP). If they mentioned ethernet handoff, they imply a RJ45 connection to your equipment.

Re: Ethernet handoff

I have a router which has inbuilt 16 port switch module and so how to check if it has a port that supports this ethernet handoff?

Re: Ethernet handoff

You have 16 ports with RJ45, it does support ethernet handoff.

Re: Ethernet handoff

How to configure a port on the switch for making it to route the traffic using ethernet interface rather than the serial link?

Re: Ethernet handoff

karthik,

Your question is too vague.

We need more specifics. Network Diagram, current configuration, network requirements, hardware involved, etc.

The more information the better, a one liner won't cut it.

Re: Ethernet handoff

currently there is a serial link between two routers but because we are doing ethernet handoff on one router, i want to know how to make routing possible?

Re: Ethernet handoff

Just move the IP address under the serial interface over to the ethernet interface, if you are planning to keep the same P2P WAN subnet.

If you are planning to create a new P2P WAN subnet, then you need to include it in your current static/dynamic routing configuration.

Re: Ethernet handoff

Just to add on this: if my ISP delivers it as Fast-E handoff, is it still better to terminate it on a router or just directly on a switch?

What's the advantage of ordering an FE hand-off instead of the old-school serial interface?

I hate to answer with a question but,

how much bandwidth can you fit via that serial interface ?

New Member

Re: Ethernet handoff

It fits upto 1.5Mbps on that serial interface..

Re: Ethernet handoff

That's a point. But a DS3 card can give me a full 45 Mbps which is more than adequate for my application :-)

By the way on the other question what's the better wait to terminate it? On the router FE port or switch?

Re: Ethernet handoff

45Mbps at what cost ? :)

You can get a 100Mbps hand-off much cheaper nowadays ...

To answer your other question, it can terminate on either device. Choosing one over the other doesn't make better but it needs to meet your network design requirement.

If you have an office with a 10Mb hand-off, it's easier to drop a 3560 or 3750 switch and have the WAN and office connecting on the same device instead of having a router connecting to a switch.

Re: Ethernet handoff

the switch module that i have doesn't support layer 3 routing .... so i got struck to as how to terminate it... probably i need to buy a new 1800 router to get an ethernet interface or buy a HWIC card...

Re: Ethernet handoff

Yes it does, you need to configure SVIs (Switch Virtual Interfaces) to route between those ports, just like a typical Catalyst Switch.

interface fx/x

switchport access vlan 2

interface vlan 2

ip address x.x.x.x y.y.y.y

Re: Ethernet handoff

i got it but is it a good practice to do that way

Re: Ethernet handoff

Sure, that's how it's intended.
