Datatransfer with Nexus 5548UP over two Vlan's very slow

[christianhabermehl]

I have a problem with my Nexus 5548UP.

The data transfer between 2 Vlan's is very slow.
Data transfer in same vlan's is ok.

Have installed a L3 card and a LAN_ENTERPRISE_LICENSE

Inter-Vlan routing works.

See pictures:

Here is a PC in vlan 30 with 10Gbit SFP+ on the Nexus
and the other PC in Vlan 100 on a Catalyst with 1Gbit RJ45

Here is a PC in vlan 30 with 10Gbit SFP+ on the Nexus
and the other PC also in vlan 30 on a Catalyst with 1Gbit RJ45

How can that be??

FTP, SMB, HTTP, any connection.

I am on the trail of the solution.

Remove L3 module and install L2 module
Install NX-OS 5.0(3)N1(1b)
Poweroff the Nexus
Remove L2 and reinstall L3 module.
Install License

Test

Hello,

just out of curiosity, did that work ?

[christianhabermehl]

Almost. The L3 module was designed as a ,,powered-up,,
displayed. Then I installed the LAN_BASE_SERVICE License. After that the module was displayed as ,,OK,,
displayed. After a restart, I get an error. Then the restarts, as soon as the login prompt appears, the Nexus restarts again and again.

I don't know what else to do.
Now the L3 module is finally displayed correctly and more problems are coming.

I have no more desire with the ding...

Does anyone know a solution?

Hello,

what is the part number for the layer 3 daughter card ? I think there is a version 1 and 2...

[christianhabermehl]

Version 2

[Georg Pauwen]

Hello,

not sure how you exactly swapped the module, but I assume you powered the switch down first ?

-->  For the Layer 3 GEMs (N55-M160L3 and N55-M160L3-V2) in the Cisco Nexus 5596UP switch, you must power down the switch first. These expansion modules are not hot swappable.

[christianhabermehl]

Yes, i powered down first. I know that.

[Georg Pauwen]

Hello,

these errors you see might as well indicate a hardware failure. I guess you don't have another L3 module available.

The entire 'issue' could be caused by faulty hardware. Is this a new module, did this ever work properly before ?

[christianhabermehl]

ebay. thats says it all.

Ohje..
