Cisco Switching/Routing :: Nexus 55548UP - 1GE SFP Module Not Recognized In Fabric Extender
Oct 17, 2012
we installed copper and fiber sfp modules in the 2232PP and none would link up. we pulled the sfp modules out and entered the speed 1000 command and re-inserted the module with no success. the same sfp modules works fine in every other cisco device. we must be missing something. running latest nx-os software.

Need clarification on the VPC with 5k and 2248 Fabric Extenders. My question is can each fabric extender uplink to two different 5ks, and at the same time, have servers connected to two both fabric extenders with a VPC.So basically, the server NIC will team with two different fabric extenders, and each fabric extender will connect to two different 5k's.
I have been tasked to replace the existing Cat 6500 and 3750 switches by Nexus 7000 and Nexus 2000.I was told initially my boss plans to get 2 x Nexus 7000 and then eventually blow up to 4 x Nexus 7000s.For Nexus, is there a list of tasks / points that i need to consider for building the initial design?
Can i just link the Nexus 7000 like the following?
N7k-A ========= N7k-B | | lots of N2ks lots of N2ks
As per my understanding, Cisco Nexus 2232 can only connect to HP c7000 Chassis if we are using a Pass Through Switch in the HP c7000. Cisco Nexus 2232 can only connect to End Hosts and not to a switch. Is there a New Feature added in Nexus 2232, which enables it to connect to a Switch like HP Flex Fabric ?
How to properly power down the Nexus 5000 and the fabric interconnect switches? I have looked up and down cisco's and google web for steps, but they are all coming back with the answer to just disconnect the power cables after you have power down all the windows os and exs servers. Before i do that, I just wanted to make sure that that's the correct way to do it or if there are actual commands that I will need to run on the devices to properly power down. I know that the FI do have a command to reboot, but i need them to completely be power down.
currently nexus 2000 and nexus 7000 does not support dual connection. you can not connect to 1 nexus 2000 to 2 nexus 7000 chasis. But for the nexus 5000, you can. what is the problem to to support this feature on Nexus 7000s? 5000s and 7000s run same software.
I am trying to install SFP-GE-T module on Nexus 5548UP Switch, but is giving the ‘SFP validation Failed’ error. The details of the switch is given below
Model : N5K-C5548UP-FA
The interface is configured with speed 1000 before inserting the module, still we are getting the same error. PFA logs for more details We have 8 Nos of SFP-GE-T modules , all are giving same error. We tried to insert the module on onboard as well as expansion module.
The same module is working fine on Cisco 3750X-24T-L Switch As per the Hardware installation guide , SFP-GE-T transciever is supported on N5K platform. Please extend your support in configuring SFP-GE-T module on N5K platform? We tried with SFP-GE-S module on the same switch , and the same is found working fine.
I am having trouble updating the epld image on the 10gb Module of Nexus 7k. we have two nexus and two 10gb module. Tried the other one and it worked fine. its jsut the first one that has problems with the epld image. i have tried on both the nexus on two different slots and still the same error.
I get the following error:
Chain connectivity is broken while upgrading the FPGA. (Error Number : 36)
Trying to find some documentation as to whether there are any other steps for inserting this new module in our N7K. We have 2 blades in already and 2 Sups in 5 & 6. I'm assuming its like the 6500s, where we just slide it in and the OS configures the global parms for it and the default VLAN.
We are looking forward to implement IBM BladeCentre Swiches connectivity with Nexus 2k module.I would like to brief you about my network over as follows:
Currentl Solution : we want to connect the IBM Blade Switches (4) as demonstrated in the attached diagram which will be connected to Nexus 2k module as Ether-channel Access port.
Initially we been proposed by our vendor with this design and Now vendor is recommending us to connect the Blade switch etiher to Nexus 5k switch or directly to 6513 core-switches instead of Nexus 2k modules as they say Nexus 2k modules are only to connect the Edge devices .
We do not have ports available on Nexus 5010 to connect the cables from IBM Blade Centre Switches. Otherthan that, incase if we go ahead and connect the IBM Blade switches as access ether-channel access port with Nexus 2k module what are consequences we have to face realted Spanning tree or any other.
One of our Nexus 7000 modules failed and generated the status below. Could this possibly be a hardware issue?
# show module Mod Ports Module-Type Model Status --- ----- ----------------------------------- ------------------ ---------- 1 0 10 Gbps Ethernet XL Module powered-dn Mod Power-Status Reason --- ------------ --------------------------- 1 powered-dn Unable to power up card (Power_OK not set)
I'm unable to get the N7K-M108X2-12L 10 Gbps Ethernet XL Module within our Nexus 7009 chassis to recognise the individual X2-10GB-SR transceiver modules. I have the same issue on another 7009 chassis.If I perform a 'show interface'. I get the following output saying SFP not inserted.
-Ethernet3/5 is down (SFP not inserted) -Dedicated Interface -Belongs to Po51 -Hardware: 10000 Ethernet, address: 7081.0599.d458 (bia 7081.0599.d458)
I also get the same result if I issue the following command. Are their any additional features I need to enable? or would this be a license issue? Have already tried different X2-10GB-SR modules, reloading the card, re seating the card. [code]
I have a 7K running 6.1 code, on F series line cards. I need to set it to prioritise DSCP EF marked traffic, that's all at this stage, but am unclear on the configuration steps required. The packets will already be marked, I just need to ensure they end up in a priority queue.
I want to prioritize egress voice traffic across a trunk terminated on an F1 module, N7K-F132XP-15. I am unsure about the setup; according to the "show interface capabilities" F1 interfaces support 8 egress queues, while the Nexus QoS documentation provides configuration referencing 4 queues. In addition, I am not clear about the relevance of network-qos on F1 queueing setup.
As per my understanding 6509 all slots are dual channel, so 9 slot * 40 per slot (20 g in and 20 g out) = 360 GB How cisco claim the 720 ?? What about the 6513 chassic switch fabric connection?
It is said that the switching fabric of WS-C3750X-24T-E is 160Gbps.Could any body tell me what is switching fabric, any relevance or difference from forwarding rate?,Is there any document to know how will the switch reach the 160Gbps full switching fabric performance?
I am looking at the utilization on a Catalyst 3560-E. I am running a test with eight 1 GIGE links RXing at 95 % utilization. All of the traffic is going to a TenGigE port. The device on the TenGigE port is echoing back all of the traffic received, so the 1 GIG links are TXing at 95% as well.When I do a "show controllers utilization", the port utilization numbers are correct, but the fabric utilization is higher than I would expect. The fabric should be 128 gigbits / second in this switch, and there is 7.6 gigabits TX/RX to the ten gig port. The fabric utilization is at 49%. I would expect 7.6 / 128 = 5.9% or possible double that. [code]
There is a cisco ws-c6509,recently it appear error log “%FABRIC-SP-6-TIMEOUT_ERR: Fabric in slot 5 reported timeout error for channel 11 (Module 3, fabric connection 1)”. When I reload the device,the error log disappear.But a few days later,it appears again.I try to replace the slot 3 (WS-X6704-10GE),the error log continues.The IOS version is 's72033_rp-ADVIPSERVICESK9_WAN-M), Version 12.2(18)SXF8"
I have four 2811 routers with IOS 12.4(15)T installed. Embedded Event Manager was introduced in IOS 12.3(4)T, why do I not have it?! I've been at this for over a month, when I try to see the command 'event manager' I get Unrecognized command? According to all EEM documentation I can find, this should work on our machines!
We are facing issue of continous packet discards On nexus4001L link (int po2) to Nexus5020 switch. Nexus4001L is installed in IBM blade center server and we have FCOE enabled in this setup. [code]
we are planning a Nexus datacenter project with this layout:Our experiences with Nexus switches are not so large until now and the manuals are very extensive.Both N5K´s should be connected directly with all 4 N2K switches. I did not find a layout like this in the manuals. Only a design,where only 2 N2K are connected to one N5K, with this fex config:Now I´m not sure if it is right to make a config like this with the same slots and fex´s or with different slots and fex´s.
I am going to install new Nexus 7K. Installed SUP and one 32-Port 10Gb module. When I open the box to install this 10Gb module, I saw that there is a carbon paper is tighted with ***** on the top of the module. confirm either it will insert in Switch with carbon paper or have to remove this carbon paper?
i have a cisco router (3900 series) and a add on module (4 x 1 Gig port module). For some reason i cant seem to port channel them and cant do routing (can set an ip address on those ports). I can do port channel and routing on on-board ports. Do i have to enable any commands to do this ?
Was wondering if anyone has ever hot ADDED, not swapped, an expansion module in a 5548up. Is a switch reboot required?I looked at the H/W install guide and it does not mention anything.
My C6506 USING ws-sup720-3B, i upgrade the IOS to the latest release of 12.2(33) SXJ1 IOS version. After upgrade and reload the machine got one module cannot be detect..WS-X6416-GE-MT, 16 port 1000mb MTRK ethernet module. The version of this are:
-HW 1.0 -FW 5.3 (1)1 -SW 8.5 (0.46) RFW
Question 1: Any tools available on cisco to check out the hardware/software compabiity feature?
Question 2: Any release note, compability matrix table etc resources.
Recently we ha a Nexus 7010 with a module frozen that was OIR (Online Remote and Insert) but do not work until reload the Nexus 7k.The command "show tech-support" has the following:
Can the encryption module (DES/ 3DES/AES/SSL VPN Encrytion/compression) for Cisco Router 3845 able to support the external connection from other high end router, for example cisco 7200? What is the maximum bandwidth, load and concurrent connection it can support?
