Hi, i have problem of synced betewin my 2 switchs nexus 7.0.3.i7.3
I use feature BGP, LACP and VRRP (also VPC etc..)
But it's impossible of configure correctly the protocol
I have many errors :
One : In log :
%ETHPORT-3-IF_ERROR_VLANS_SUSPENDED: VLANs 9-10 on Interface port-channel3 are being suspended. (Reason: peer-keepalive no
t operational, peer never alive)
I See that : https://quickview.cloudapps.cisco.com/quickview/bug/CSCvc06939
Two : show vrrpv3 brief
First switch (ok)

Second switch (missing ip?)

what is port-channel 3 ?
Looks like you have vPC configuration issue, you need to post both the nexus configuration here:
show run
show cdp neigh
show vpc brief
show vpc role
show vpc peer-keepalive
check the vPC best practice, same for all nexus devices :
05-06-2024 01:28 AM
Hello,
Please display all configuration regarding portchannel and vpc.

Thx Guys,
Show my 2 conf (switch br1 and br2)
Descriptions : My Br1 is work actually and no communicating to br2.
Also, at 24 april, i replace my BR2 material by same model and i uploaded my conf file backuped. But not work ...
Thank you for your support

peer-keepalive destination 10.0.0.1 source 10.0.0.0 vrf pka1
The source is 10.0.0.0 ???

Hi MHM,
Yes, the ip address 10.0.0.0 is br1, it's possible.

Julian

No friend
You use /31 for p2p and that not work
You need for keepalive
Four IP
One for each NSK
And one network Id and other broadcast IP
I.e. you need to use /30 at least

Also, at 24 april, i replace my BR2 material by same model and i uploaded my conf file backuped. But not work ...
is that working before April 24 ?
Do you have high level rough diagram what ports connected each other ?
My observation on the config :
1. have you created VRF ? i do not see in the config that VRF context created.
create VRF context on both the switches :
vrf context pka1
vrf context management
2. i would suggest small changes on the config and test it (make sure some of the configuration you changing may have convergence,) so understand the config apply in the maintenance window.
BR1 :
vpc domain 1
role priority 1
peer-keepalive destination 10.0.0.2 source 10.0.0.1 vrf pka1
peer-switch
peer-gateway
auto-recovery
ipv6 nd synchronize
ip arp synchronize
interface Vlan9
description interco-routers
no shutdown
mtu 9216
ip address 10.0.0.9/29 -- this changed may be required associated config
interface port-channel2
description keepalive
no switchport
vrf member pka1
ip address 10.0.0.1/29
BR2:
vpc domain 1
role priority 2
peer-keepalive destination 10.0.0.1 source 10.0.0.2 vrf pka1
peer-switch
peer-gateway
auto-recovery
ipv6 nd synchronize
ip arp synchronize
interface Vlan9
description interco-routers
no shutdown
mtu 9216
ip address 10.0.0.10/29
interface port-channel2
description keepalive
no switchport
vrf member pka1
ip address 10.0.0.2/29
Note : i am more focusing on bringing the VPC up before we can test other stuff
Also thinking that Layer 2 connection up and interface connected right port each other.
I have also requested other information as below :
show cdp neigh
show vpc brief
show vpc role
show vpc peer-keepalive
Also some reference ,my vPC testing :

that's fine - i did not find the information on your show run hence the question.
i would like to see below information if you need more assistance
have also requested other information as below : from both the switches.
show cdp neigh
show vpc brief
show vpc role
show vpc peer-keepalive
show ip interface brief
EDIT- rather another post
how ip address 10.0.0.9/29 -- this changed may be required associated config ?
instead of /31 i changed IP address to /29 to be clear

Hi,
I try with peer-switch and change mask and IP.
No result
Have you an other idea ?

So you want i change thoses values only ?

Julian
05-06-2024 09:49 AM
I think you confuse here
The keepalive is l3 port and it not need to be SVI and PO
Single link like
Gigabitethernet 0/0 is enough
And config will be in both Nexus
interface GigabitEthernet0/0
No switchport
description keepalive
no switchport
vrf member pka1
ip address 10.0.0.1/30 (10.0.0.2/30 for other NSk)
No shut
That it
