Nexus9318yc-xc

ja.aljaloud · ‎01-19-2022

Hallo,
i had a Problem with Nexus Switch 93180YC-EX, after I updated to version 9.3.8 ( it had NX-OS Release 7.0(3)I7(3) ) and everything is going ok without the ospf.
The ospf neighbours on outside interface to ISP is down, the switch can’t build more the relationship between the outside interface e1/0/7 and the ISP.
We have one link physical ( int e1/7 ) to service provider and vpn tunnel on the interface vlan 2 (SVI).
with VPN the switch can build the ospf neighbours with isp per int VLAN 2, and now we could communicate with other side, here we don not have problems.
But the interface e1/7 which connect directly to isp ( MPLS ) can’t see more the neighbours and can not build the ospf with other side, even we did not change anything in the configuration.

Note : i did the upgrade in this path : 7.0(3)I7(3) → 7.0(3)I7(10) → 9.3(8)

is this problem because of the upgrade?

thanks in advance

Hi,

When you say "outside interface to ISP is down, the switch can’t build more the relationship between the outside interface e1/0/7 and the ISP" Do you mean the physical interface is down or the OSPF neighborship? Can you post the config for interface 1/0/7? Can you also post the OSPF config?

Interface 1/7 seems to be bouncing. Can you hard set the interface to 1Gig and test again?

i ´did but i still have the issue and logging.

Do you think is the problem with SFP ?!

Reza Sharifi · ‎01-19-2022

Do you think is the problem with SFP ?

It could be especially since this is a GLC-TE.

I would replace the cable first, and then if that does not help, replace the GLC-TE

According to the Matrix, GLC-TE is supported in this platform. See link:
