Nexus 5000 interface vlan ping

opnineopnine · ‎08-10-2016

Hi all,

I have two 5000 on different sites, connected via dark fiber, I have this interface in mode trunk and I allowed all vlans.

When I do a show cdp neigh I can see both devices, but when I do a ping between sites I loose all my packets.

Any ideas?

thanks.

Hi,

Is the source and destination IPs configured correctly?

Can you provide the config for the vlans and the IPs?

Hello Reza,

Site 1

vlan 60

inter vlan 60

ip add 192.168.1.10/24

!

Site 2

vlan 60

inter vlan 60

ip add 192.168.1.14/24

Thanks!

And vlan 60 is added to the trunk between the 2 switches?

Are the interfaces in up and up mode on both switches?

sh ip interface vlan 60

Yes the trunk is a trunk vlan all, and the interfaces are up.

thanks.

Can you ping using the source interface?

site 1

ping 192.168.1.14 source 192.168.1.10

I dont get any answer, but if I do a trace.

traceroute to 192.168.1.10 (192.168.1.10), 30 hops max, 40 byte packets
1 192.168.1.14 (192.168.1.14) 0.852 ms !H 0.384 ms !H 0.218 ms !H

thanks.

Since these are 5ks, it inter-vlan feature enabled on both switches?

Hi,

I found that the issue is spanning tree that is blocking on one side in the interface that I use for the dark fiber I added , but still the same issue.

interface Ethernet1/31
switchport mode trunk
spanning-tree port type network --- added

thanks.
