Nexus 5548 - keepalive recommendation

[udo.konstantin]

Hi all,

I know for N5K is best practice to use the mgmt0 interface for keepalive.

In our case it isn't possible to use this copper port.

Is it a good practice to use a routed port-channel as a point to point link between the two devices and put them into a separat vrf ?

int eth1/7 - 8

no sw

channel-group X mode active

int po X

ip add x.x.x.x/30

vpc domain 10

peer-keepalive destination x.x.x.2 source x.x.x.1 vrf vpc-keepalive

The N5K has a Layer 3 modul and licence

Thanks

Udo

That is a valid configuration but you don't really need a port channel. 1Gbps will be sufficient.

If this ink fails it has no impact on the vPC domain or data forwarding:

Thanks sean...

In most technical docs I don't see the difference between a N5K with or w/o Layer 3 module. But this this is important regarding the creating of a separat vrf and a dedicated L3 Link.

Without this it isn't possible to create a L3 Link nor a L3 Portchannel.
