N5K interface without L3 Modul

HUBERT RESCH

Level 3

Hi, it is possible to configure SVI Interface on N5K ( when enabling feature interface-vlan) for example to use for inband-management.

Is it also possible to configure an IP address on a physical interface (no switchport) for management reasons.

The N5Ks we use does not have a L3Module in.

Background: we have to use the interface mgmt0 for outbandmanagement, because we need 100BaseT.

So we need another interface for vPC peer keepalive.

two theoretical possibilitys

1. configure phys interface as an accessport of a particular " peer-keepalive-vlan" , configure an interface vlan for this vlan in a seperate VRF, and use this interface vlan for vPC peer-keepalive.

I do not like this because it can easily happen that by error also other interfaces are configured in the same vlan..

2. my prefered way would be to configure a physikal ethernet-port like following

vrf cont vcppeerkeepalive

int eth 1/1

no switchport

vrf member vpcpeerkeepalive

ip addre 192.168.1.1

no shut

it is possible to configure it, but the interface remains down ( shows ..protocol down, L3 not ready)

Is is not supported to configure it in is way or did I make another mistake ?

Thanks in Advance

Hubert
