Cisco Switching/Routing :: Nexus 2232PP / 3750 S - Support 100Mbps With A SFP-GE-T
Nov 10, 2012
The data sheet for the 2232PP says you can use a SFP-GE-T, but there is no mention of 100Mbps. I want to recommend to a customer that they use 2232PP for an upcoming core upgrade, but it may need to support some existing 100Mbps devices which are currently connected to 3750s.
How to get GLC-T sfp modules to be recognized by a Nexus 2232PP? [URL] GLC-T are supported, however I am getting:
"Ethernet102/1/1 is down (SFP validation failed)"
from a sh int eth102/1/1 for two different Cisco GLC-T sfp modules (30-1410-02 and 30-1410-03) and a third party GLC-T-JTS. I have verified that all three modules work when plugged into the NExus 5596UP that I have.I am running NXos 5.1(3)N1(1a)
the phone connects to the 3750-A access layer switch (VTP mode client) which connects to the nexus 5596 (The nexus is the layer 3 device and set to vtp mode server) and finally we have a Voice recorder that connects to another access layer 3750-B switch.(VTP mode client)
For voice recording I need to setup RSPAN and the nexus5596 does not support RSPAN will the following have any impact on the nexus
IF I move the 3750-B to VTP server mode and run the command remote span on the VLan I need to Rspan its going to update the VTP data base in short it will update the vlan.dat file for all the switch in that VTP domain.
AS the vtp update reaches the nexus saying there is a change (keeping in mind the nexus does not support rspan not sure hows its going to handle that request and how its going to update its vlan.dat file)
Is it going to incremment the VTP revision number? can it crash the vlan.dat file on the nexus ? or do nothing and ignore the update and stop the update from proceeding to the 3750 A switch?
Does the nexus 7010 support virtual switching yet? All of the posts I have found from about a year ago say that it is going to be supported, but there were no dates listed. I heard the same thing from Cisco a while back, but haven't followed up with it.If it is supported finally are there any configuration guides available for it?
We recently purchased a pair of 2232TM Fabric eXtenders just to find out that our Nexus 7000 does not support it. Will there be support for the 2232TM FeX in Nexus 7000 any time soon?
if vPC is supported between a single 2232PP FEX and two 7000 switches running 6.0(1)? I have been researching this for an implementation I am doing for a client and was able to determine it was not supported with earlier versions of 5.0 when the FEX is connected via vPC as I described above, but I can't find anything related to version 6.0(1). I have done this for other clients with 5000 and 2000 switches, but I don't have too much experience with 7000 switches.
Iam having some issue trying to configure snmp-server context vrf XXX.From some reason even if i put my VRF name i cant see anything about this vrfthis is the command i add:
future support for IP Sla on the nexus 7000. The latest info that I've seen is that it will/could be supported in release 6.2, scheduled for mid 2012. Does this still accurate?
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.
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 deploying a pair of Nexus 5596's with 3750 POE switches in the closets. I'm looking for a best practice as how to configure the Nexus 5596 to support proper QoS for EF at the core.
I am sure that F1 linecards on Nexus weren’t able to support L3 functionality, so my query is does the F2 linecard (N7k-F248XP-25) on Nexus 7010 support Layer 3?
I have a customer who is having some issues with 5m passive HP twinax cables, 537965-001, with a Chelsio 10G NIC. Aside from NIC driver issue, if NX-OS recognizes this SFP+, should it be expected to work in a 5020 running 4.2(1)N1(1)? Whether Cisco has certified passive HP twinax cables? I have included output to 'transceiver details' to a Cisco twinax and the HP (WL GORE) cables.

I have a 3750 running 12.2(55) and when I configure BGP I only get the standard AS number choice of 1-65535, but my provider is supplying a 4-byte AS number which is six digits and it gets rejected at the prompt on the 3750. Does that mean no support on 3750
Nexus 5500 support auto negotiation on 1gig sfp port? There is an end device that only support auto negotiation and cannot be manually set speed/duplex.
I've had a read through the docs for the 3750 series switches, but nothing that definately says that jumbo frame routing will work on a SVI.One part specifically I'd like clarification on is:The default maximum transmission unit (MTU) size for frames received and sent on all interfaces on the switch or switch stack is 1500 bytes. You can change the MTU size to support switched jumbo frames on all Gigabit Ethernet and 10-Gigabit Ethernet interfaces and to support routed frames on all routed ports. It says supported routed frames on all routed ports, but this in the past has meant physical ports, and not Virtual ones.
My network consist of that network device. cisco catalyst 3750 with stackwise, 2xnexsus 5000 series and servers.servers connected to nexsus switch. nexsus connect to 3750.
Each server have two link, one of them connect nexsus1 and other connect to nexsus2 switch.(same traffic) each nexsus have one link to 3750. At 3750 the nexsus link configurate etherchannel. but the flapping occur at 3750.
i understand that at 2 nexsus link have the same server source mac address so the flapping occur at 3750. how i solve this problem?
I got the error in object when I try to add a new HSRP group in new vlan.All the HSRP group has the same HSRP group the 2.another way to provide clients's default gateway redundancy for each Vlan intead to use the HSRP?
what is the difference between Cisco Nexus switches and the usual catalyst 3750 switches.I do understand the operating system in both these are different.
When will we suggest using Cisco nexus instead of usual Cisco switches? Also what interface does Cisco nexus like 5548 come with , is it both copper and fiber?
I have defined a trunk between a nexus 5k and cat 3750 as a pvlan trunk - now I would like to add redundance and performance and tried to establish a vpc between my par of nexus's and the 3750 stack - but the nexus tell me that the port-channel doesn't support pvlan's - and then - ehh - do I get any benefits of running the trunk as a pvlan trunk at all?
Does Nexus 7K support Multiple VDCs sharing ports on a single line card. One of our cisco parnter engineers stated that cisco doenst recommend using same line card for multiple VDCs.The second VDC (Non-Default VDC) will be used four our Outside, and DMZ Segment, and to phyiscally segregate our Firewall from our Internal/Inside Core Switch without using a physical DMZ Switch.I know Cisco used the Nexus in this way in their PCI DSS 2.0 Compliance Document. Module is N7K-M148GT-11L

I'm looking for switches that support single mode fiber connections and would like to know if "WS-C3750-FS-S Catalyst 3750 24 100BaseFX + 2 SFP" and "WS-C3750G-12S-S Catalyst 3750 12 SFP" can serve the purpose?
I believe the answer is yes, but incorperating more layer 3 features of our 3750's, I want to know if they fully support EIGRP or OSPF?
Also for a small business of 4 locations, each with a 10mbps fiber and a 1.5mbps mpls... wouldn't you say EIGRP would be easier? Want to look at making the failover automatic if the 10mbps fiber goes down between a site, then the network fails over to 1.5mbps mpls. When the fiber returns in service then the network automatically preferr the fiber again.
Currently we use static routes and if there is a provider outage we have to manually edit the config to flip flop the routes.
I heard that the WS-C3560E-24PD-S and the WS-C3750-48PS-S have a limitation on the number of 7945s supported (ie i can only run 10 or 15 on each switch before the power runs out). Any knowledge with these pieces of equipment verify the maximum supported? I'm having trouble finding documentation showing any maximums.
