we need a help with this issue,
we have configured VpC between two Nexus 5596, for Vpc-Keep-alive-link we configured L3 interface with 1G (GLC-T) ,it shows the below status message "L3 not Ready" with interface LED glows in Yellow in color. is this a physical layer problem

If you look at port e1/17 on each switch and the link light in not green, than you have physical layer issue. Is the patch cord good?
is the GLC-T working fine? what is the output of "sh int e1/17 tran"?

As soon i change the interface from L3 to L2 interface it turn's to green colour.

Can you add switchport vlan x/x to both switches and try again?
see below example
vrf context vpc_keepalive interface Ethernet1/31 switchport access vlan 123 interface Vlan123 vrf member vpc_keepalive ip address 123.1.1.2/30 no shutdown vpc domain 1 peer-keepalive destination 123.1.1.1 source 123.1.1.2 vrf vpc_keepalive

Hi Karthik
In your output:
Peer status : peer link not configured
vPC keep-alive status : Suspended (Destination IP not reachable)
1. check whether you have Port-channel between your n5k configured as vpc peer-link, and it's up
2. check whether you can ping
123.1.1.1 from 123.1.1.2 in vrf vpc_keepalive

Thanks Oleksandr Nesterov,
i have not configured vpc peer-link command in the port channel between N5k, i have added the key-word now it is up and running .

Hi Oleksandr Nesterov, happy new year
thanks for your support , all are up and running ,but i dont understand why we got this status message when it was an Routed interface, please help me to understand this.

Hi Karthik
Please check "sh mod" and "sh lic usage".
If L3 module was down or license was absent such behavior might be observed.

Hi Oleksandr,
i was in vacation so i didnt reply for this thread , yes you are right i have verified the device with both commands 'show module' & 'show license usage'.
In 5596, L3 (LAN_BASE_LIC) was not there, we installed the license all routing related things started to work.
In 5548, L3 (LAN_BASE_LIC) was there but there is no L3 Daughter card , we cleared the L3 license it rolled back to L2 operatons. we are using 5548 switches mainly for L2 operation so we did not install the L3 daughter card , for all L3 opration redirected towards 5596 like HSRP,inter-vlan routing.
Out of this what i understood ,
If we want to use Nexus 5500 as an L3 switch , we need both(1&2) requirements to be there
1.we need L3 module
2. we need L3 license (LAN_BASE_LIC)
Your show commands helped me to clear the issues, Thanks!!!!!!!!!!!!!!!!!!!!!!!!!!!
