Hi all,
I fully agree with Nayan and all the others, who are hit by this problem; it can't be a solution to put a single switch in place behind a pair of NX 9300. This has to be fixed immediately.
We had an old Catalyst 4510R in place before, which we replaced by NX9300. Before it worked perfectly and now we are spending hours and hours trying to find a solution.
We are dealing with this for more than a year now and the customers are getting impatient.
Cheers
Roman

I'm fully aware of the bug and parity errors. According to TAC the bug has not been fixed in our running release.
We re-seated the linecard in question and it's ok now.

No, we did not. I recommended the customer to use ITD as loadbalancing mechanism instead of MS NLB. This means that we had to buy the network services license for the 2 Nexus.
Until now we don't have new feature in place due to some time constraints @the customer.

Hi Mark,
that's exactly the case; I just received an answer from TAC saying the same; the bug was not fixed and therefore carried over to the release we're running.
I'm adviced to upgrade to 15.1.2-SY7
Best regards

Hi Leo
many thanks for your reply; I fully agree with you; I'm also familiar with the "recommendations", but I have some of the 3560x running with 15.x without any problems.

I've seen that many discussions already have been raised about the high CPU utilization of the Hulc LED process on 3560X-48PS. We face the same issue on all of our 3560X with Hulc LED process of around 20% to sometimes 40%. Displaying the process cpu history shows that it is constant around 40%.
We also face performance issues on the devices with the Hulc LED process around 40%. It is the only process with this high utilization.
I read different infos about the purpose of this process, reaching from checking layer 2 traffic to checking the ports (PoE etc.).
Can anyone finally explain:
1. The purpose of the Hulc LED process
2. Why the CPU utilization of 20% is a normal condition ? In my opinion this far to high
3. Can the process be influenced by changing the configs (I read in one post that the command "switchport trunk allowed vlan ...." on the uplinks solved the problem)
Any hints and tips are very welcome
Regards
Roman

Hi Nicolas, thank you very much for your reply.I've already checked CSCuq03168. Do you eventually have any infos about the timeframe Nexus 9300 will support this deployment ? In the meantime we configured the MS-NLB to unicast without following TAC doc 118951. Unfortunately we were not very successful - we were even not able to access the VIP anymore. So my next thought is to try IGMP, which is supported on MS NLB running under Windows Server 2008 R2. Do you have any experience with this ? I really appreciate again your reply

Hi all, I have the following setup: 2 Nexus 9372PX (NX-OS Release 7.0(3)I1(1a) ) in a VPC-Configuration 4 Nexus 2248TP-E, 2 are attached to Nexus_1, 2 are attached to Nexus_2 Attached to one of the FEXs is a Microsoft NLB (mac_addr 03bf.0a04.023c, ip_addr 10.4.2.60), which is configured for Multicast-Support. Customer is using Microsoft NLB for MS Exchange. I've added a static ARP-entry on both 9372PX (see below) interface Vlan42 ip address 10.4.2.254/24 no ipv6 redirects ip arp 10.4.2.60 03BF.0A04.023C hsrp version 2 hsrp 42 preempt ip 10.4.2.1 ip dhcp relay address 10.4.2.100 ip dhcp relay address 10.4.2.101 Clients are connected to several VLANs, eg. VLAN 8 (10.6.8.0/24); SVIs are configured on the Nexus 9372PX. I tried to add the following command which gave me the error-msg since this is obviously not supported on Nexus 9372PX. mac address-table static 03BF.0A04.023C vlan 42 interface po 41 ERROR: Multicast/Broadcast MACs are not supported! Since we migrated from an old Catalyst 4510R, we are facing extremely slow response-times or even time-outs in MS Outlook. We are looking for a good workaround. Any hint or tipps are very much appreciated. Best regards Roman

Hi Jason many thanks for your reply. We tries this according to your suggestions but for some reason, we don't get it printed as we see it on the screen, where the output seems to be correct and in German. We will try any further
