Tx pause frames on nexus 5548

Hi guyz,
i am experiencing an issue with the fex's ports to which some servers are connected. These are sometimes not reachable via a ping and i realise a lot of Tx pause frames. could this cause this issue?
Inmy configuration, i have the send admin and flow control operation control set to on and the receive admin and its flow control operation set to off. what is the recommended configuration of this?
thanks for the help in advance.

Flow control is enabled on by default on FEX and recommended to leave it on. I would not suspect this to be cause of your ping issues though.

Cisco Nexus 5K's Tx Pause Frames with no Rx frames

We have an EMC SAN connected via 10G links on a 5010. At some times we have iSCSI disconnects generated by the SAN.
We are seeing Tx pause frame, but no Rx frames. No packet loss, no errors. The "normal" utilization is around 23Mbit.
Under what conditions might this happen?

hi Victor
I cannot answer your question but confirm what you are seeing. As far as I am aware of these Tx pause frames are send from the SP when it cannot catch up with switch. If you will re-act on the pause frames you have to activate flow-control on that particular interface. I would expect that the iSCSI protocol handles the session so that it doesn't loose any packets
It is local control packets between the SP's I/F and the Nexus I/F and the nexus hasn't got much buffering to pace a flow with.
We are seeing this behavior between nx5010 switches and EMC VNX5500 SAN. I don't think your disconnects have any thing to do with the pause frames.

Link Error Nexus 5548

Hi All,
I have issues with Nexus 5548 ports 1000Gb ports. They go down after sometime with the error " Link not connected " while the links are connected. When i move the connections to other ports they work but after a while the go down again with the same error. I can confirm that is currently down was working and its currently connected. Has anyone seen the error before?
Kindly see the output from the interface thats currently down below:

Hi Leo,
What confuses me is that the connection was working. I used the correct cable and the port type as well. How do i resolve this?

Command to see transmit qeueing drops in Nexus 5548

Hello, 10g links in our core are getting rather congested as seen by MRTG graphs. Any command on Nexus 5548 to show transmit queuing drops on a given interface?

You could use #show queing interface eth 1/1
it shows you output similar as below:

UCS FI 6248 to Nexus 5548 San port-channel - not working

Hi all,
I'm sure I am missing something fairly obvious and stupid but I need several sets of eyes and help.
Here is the scenario:
I want to be able to create san port-channels between the FI and Nexus. I don't need to trunk yet as I can't even get the channel to come up.
UCS FI 6248:
Interfaces fc1/31-32
Nexus 5548
interfaces fc2/15-16
FI is in end-host mode and Nexus is running NPIV mode with fport-channel-trunk feature enabled.
I'm going to output the relevants configurations below.

Very low transfer speed issue on SUN4270 M2 server connected with nexus 5548 switch on 10GB fiber.

                   Hi,
I have 2 SUN 4270 M2 servers connected with Nexus 5548 switch over 10Gb fiber card. I am getting performance of just 60 MB per second while transfer of 5Gb file across 2 servers. The similar speed i use to get on 1Gb network also. Please suggest how to improve the tranfer speed. On servers, ports ET4 and ETH5 are bonded in bond0 with mode=1. The server envrionment will be used for OVS 2.2.2.
Below are the details of network configuration on server. I quick help will be highly appriciated--

Hi,
Thanks for reply..but the RX errors count is keep on increasing and the transfer speed between 2 servers are max 60MB/ps on 10GB FC card. Even on storage also, i am getting the same speed when i try to transfer data from server to storage on 10GB FC card. Servers and storage are connected through Nexus 5548 switch.

FCoE with Cisco Nexus 5548 switches and VMware ESXi 4.1

Can someone share with me what needs to be setup on the Cisco Nexus side to work with VMware in the following scenario?
Two servers with two cards dual port FCoE cards with two ports connected to two Nexus 5548 switches that are clusterd together. We want to team the ports together on the VMware side using IP Hash so what should be done on the cisco side for this to work?
Thanks...

Andres,
The Cisco Road Map for the 5010 and 5020 doesn't include extending the current total (12) FEX capabities. The 5548 and 5596 will support more (16) per 55xxk, and with the 7K will support upto 32 FEX's.
Documentation has been spotty on this subject, because the term 5k indicates that all 5000 series switches will support extended FEX's which is not the case only the 55xx will support more than 12 FEX. Maybe in the future the terminology for the 5k series should be term 5000 series and 5500 series Nexus, there are several differences and advancements between the two series.

Prime Infrastructure 2.0 and Nexus 5548, SSH credentials fail

Hi,
I'm having problem getting the Prime Infrastructure 2.0 to login with SSH to a Nexus 5548 to do an inventory. I get "Wrong Telnet/SSH credentials". But when I use the same credentials from another SSH-client it works fine. I also tested to SSH from the console of the Prime-server and that also works fine.
Any ideas???
Regards,
Stefan Lindkvist

I have PI 2.0 working against Nexus 5k's in two different installations. See below for an example (click to enlarge).
Have you put in an entry in both the login and enable fields (even though they are not separately required when logging in directly)?

Telephony Issues on Nexus 5548

Dear Viewers,
I have Nexus 5548 devices in one of my client data centers and i have one 3750 switch to which all of these Avaya voice servers connect.
The 3750 switch was initially connected through a L2 Link to a 6509 catalyst switch and the telephony applications were working correctly.
The problem arises when i move this 3750 layer 2 link to a Nexus 5548 (OS version 5.1(3)N1 switch. All telephony calls coming from the outside (External calls) are not working as required but the internal calls work as usual.
What is odd is that when i migrate this L2 link back to the 6509 switch, all works as usual. This is just a layer 2 connection and i am wondering why this is not possible.
The vlan is accepted on all relevant trunks. I also deactivated igmp snooping on this voice vlan on the Nexus 5548 thinking it would help but in vain.
Any ideas and suggestions are welcome.
regards.
Alain

This is my radius config...... on a 5K

Fabric with two Nexus-5548 and a brocade switch does not get fabric updates

We have a fabric containing two Nexus 5548 and a Brocade 5000 switch in interop mode 2. When i make changes to the zoning, the first nexus (the fabric principal) and the brocade switch see the zone changes. The second Nexus switch does not see it. There are no error messages but the change just can't be seen. What can i do to find out, what goes wrong ?

Ouch, deprecated is not the word i wanted to read
We are using 5.1(3)N1(1a) on nexus-rz1-a
and 6.0(2)N1(2) on nexus-rz2-a.

Install pbr feature nexus 5548

I am in need of Policy Based Routing for a new project. At my core I have a couple of Nexus 5548s clustered together. I go into configure terminal and run the command "feature pbr" and the return is invalid. So I check the license with the command "show license usage" and I get the following output:
Feature Ins Lic Status Expiry Date Comments
Count
FCOE_NPV_PKG No - Unused -
FM_SERVER_PKG No - Unused -
ENTERPRISE_PKG Yes - Unused Never -
FC_FEATURES_PKG Yes - Unused Never -
VMFEX_FEATURE_PKG No - Unused -
ENHANCED_LAYER2_PKG No - Unused -
LAN_BASE_SERVICES_PKG Yes - In use Never -
LAN_ENTERPRISE_SERVICES_PKG Yes - Unused Never -
From here I see that the enterprise package is installed and is unused. How can I gain access to the enterprise features? I found a document here that says "Ensure that you are in the correct VDC (or use the switchto vdc command). " The switchto vdc command is also invalid. What am I missing?
Eric

I realise this is a very old post however I wanted to post here in case others are still looking for this feature. PBR is now supported in version 6.0(2)N2(1) on Nexus 5k.

TACACS Nexus 5548 Authorization

I am having an issue with authorization on the Nexus 5548. Note: The tacacs configuration has and still works correctly with all non-Nexus gear.
Authentication succeeds, and initiatial authorization passes. However, all sh and config commands fail, though AAA Autho Config-Commands .... and Commands Default Group <Grp Name), are configured.
ACS generates the following error: 13025 Command failed to match a Permit rule. The Selected Command Set is DenyAllCommands. I created an AllowAll, but am unclear how to associate this with Access Policy.
Any help would be greatly appreciated.

Hello,
Hope the attached document points you into the right direction.

Nexus 5548 L3 daughter card flapping

Hi guys,
Anyone of you here that experienced the logs below on their Nexus box:
2011 Dec 12 06:24:45 GDCNXS5K01 %BTCM-2-BTCM_LOG_ROUTER_ERR: router card in slot 3 has internal link(s) flapped: router ports down: 0x1a108000 0x1a109000 0x1a10a000 0x1a10b000 0x1a10c000 0x1a10d000 0x1a10e000 0x1a10f000
I am getting this log at least once a day. Seems like it is shutting down the SVI of the box after the said log occured. Good thing I have enable vPC and I am able to access the NXS5K through the vCP keepalive link (mgmt).
I have two Nexus 5548, but only one is experiencing the said error.
Any inputs, suggestions would be greatly appreciated.
Thanks,
Edzel

We had this same problem this past weekend, only in module 2 on a 5596.
In our case, we had rebooted our primary Nexus and found the following message immediately preceeded the BTCM error you noted:
%$ VDC-1 %$ %NOHMS-2-NOHMS_DIAG_ERROR: Module 2: Bootup diag detected major event: Forwarding ASIC failure: Ethernet2/9 Ethernet2/10 Ethernet2/11 Ethernet2/12 Ethernet2/13 Ethernet2/14 Ethernet2/15 Ethernet2/16
We replaced the module. A "show diag results module 3" would probably show you the same thing. However, I don't think the error message will show up until you reboot.
If your flapping Nexus is secondary, you probably won't notice anything major, but if it is your primary, it would probably affect your routing.

Pause Frames in 2950-LRE

Hello experts,
I have an eight port 2950 Long Range Ethernet switch, model WS-C2950ST-8-LRE, with sw image c2950lre-i6l2q4-mz.121-22.EA5a.bin. I have CPE585 on the other end of the lre link. The distance is about 250 meters. When I issue the command,
sh controller ethernet-controller, I see the following on one of the lre ports (this is a partial output, it details on all the lre ports).
LRE Enet Stats on Switch:
Transmit
1971984524 Bytes
176387421 Frames
14274008 Pause frames
Can somebody please tell me what does the Pause frame mean? Why am I seeing these? How can I eliminate this pause frame?
The applications (especially MS Project) running on PCs on the other side connected to the CPE have very slow response time. Some of them time out due to slow response time.
I have rate selection sequence LRE-SEQ-COMPLETE-REACH and profile LRE-15LL for each of the LRE port. Is there anything else that I can do to improve the performance and get rid of the pause frames? Thank you for your assistance.
Murali.

Thanks for the reply. In my case, the lre sits between two 2950T switches, i.e., uplink via g0/1 port and downlink via an etherchannel with CPE 585 on the other end (2 lre ports connecting to two fast ethernet ports on 2950T). I am not sure what setting I should use and where to turn off this feature. Or is this normal on an LRE switch where the uplink is a faster link and the downlink is a slower link (according to the profile on the lre links, I should be getting 18 MB transmit and 16.67 MB uplink on each of the lre link of the etherchannel).
Looks like it is not a bandwidth issue because the Ciscoview shows the utilization on the interface to be less than 10%. It has to be something to do with latency or other feature on the lre that I am not aware of.
Any suggestion is greatly appreciated. Thanks.
Murali.

Servers connected to Nexus 5548 only getting 200 Mbps of throughput

Servers connected to NExus 5k were only getting 100 Mbps of throughput. So I disabled Flow control recieve on all the ports. After this we are getting 200 Mbps of speed. The servers are connected throuh 10 gig port. Could you guys please suggest why the throguhput is still low? Atleast we should get 1Gbps of thrpoughput.

Hi Adam,
I think we probably need a little more information to go on. Can you answer the following?
What type of servers and NICs?
What OS are you running on the servers?
What cables do you have from the servers to the switch?
Are the two servers in the same subnet or is the traffic between them routed?
If routed, is that in the Nexus 5548 or some other router?
How are you testing throughput?
Presumably you're not seeing any errors on the switch ports that the servers are connected to?
Regards
