Cisco Switching/Routing :: X2-10GB-LR And Receive Power In 6500
May 1, 2012
We are having troubles getting a 10Gig interface to come up with a carrier... it shows down down.We are using X2-10GB-LR on a 6500 and SM fiber, distance to carrier hand off is about 90 feet.
According to: [URL]
The receiver power on a X2-10GB-LRis
Max
0.5
Min
-14.4
Our carrier is sending at +5db. Currently the interface is down.
My question is; would the interface even come up if it is receiving a powerful signal?
Here is DOM output for our interface.

I have a 6500 chassis with 2 power supplies. At the moment I am using the default configuration:
power-redudancy mode redundant
The problem is that an inserted module is in "power deny" state due too insufficient power.
I know, that It's not a good idea to change into combined mode (loss of redundancy), but my customers requested this anyway.
So I will change to combined mode. So here's the 1 million dollar question: "Which modules will go into power deny, if one of my power supplies fails?"
The 6500 config guide states:
"Power supply is removed withredundancy disabled
• System log and syslog messages are generated.
• System power is decreased to the power capability of one supply.
• If there is not enough power for all previously powered-up modules, some modulesare powered down and marked as power-deny in the show power oper state field."
Well, do you know if there's any way to configure some kind of priority? E.g. I definetly don't want by 10Gig Module or WiSM module to be in power deny. Can i statically make sure, those module will be powered on for sure? Like: "power enable module slot_number" How is this calculated? Or is random?

We have two 6500s. One is running in power redundant mode and the other is running in combined mode.We need to change the one running in combined mode to redundant mode to ensure it can run ok on one supply if needed but I have a couple of questions.
1. Assuming that we are not oversubscribed on the power allocated, does changing the mode cause any disruption?
2. The switch running in combined mode seems to have allocated some power for an "Inline Local-Pwr-Pool" which is not allocated on the switch running in redundant mode (see attached). Does this allocation will be needed if we change the power mode?

I know that the 6500 with a Sup 720 reserves power for a redundant 720. If there is no plan to install that redundant Sup, is there a means of releasing that reserved power? I know that one approach would be to insert a card into that slot to cut the reserve down, but I need to reclaim all of that power.

Cisco IP phones attached to a Moduke in one of my Cat6500 access Switches suddenly went down. Upon closer inspection of the Switch Sys log, I observed the following Sys log error messages: [Module 9 is experiencing the following error: Inline Power Module - PS Voltage bad. ]A sh Mod output indicates the PoE daughter card and Main Module are "ok" - see attached output. It appears issue is related to the the actual Power Supply module and not the blade module and installed PoE Daughter card. I am inclined to open a TAC case for a PS replacement, but wanted to see if this can be resolved without a hardware replacement. At this time all 48 IP phones attached to this module are out of Service.

The following discussion is based on cisco cat 6500 switches with two power supplies: p1 and p2. . Both power supplies are running in combined mode .Each power supplies is rated with 500 watts max( I just picked 500 watts for simplicity)Combined mode In combined mode, each power supply provides approximately 83% of its capacity to the chassis. This allows for greater utilization of the power supplies and potentially increased PoE densities
1) Let say our specific 6500 switch's configuration requires 1000 watts. We have two power supplies p1 and p2 ,each with rated power of 500 watts. Both power supplies must operate in combined mode. Will power supplies be able to meet the total load power requirement of 1000 watts?
Here is my understanding :The maximum power delivered by each power supplies is 83 percent of its rated power, assuming power supplies are running in combined mode.
So Maximum power delivered by power supplies
= 83% of p1+ 83% of p2
= 83% of 500 + 83% of 500
= 415 +415
=830 watts
Thus the required load of 1000 watts can not be met by our power supplies in combined mode.
2 )Suppose our switch's switch configuration needs 500 watts. Again our power supplies each rated with 500 watts, are configured for combined mode. How much power is being delivered by each power supply? Is it 83 percent of the total load i.e 500 watts?

can I plug power supply from 4500 to 6500? more specifically we have power supply PWR-C45-1300ACV. And we need to place some power supply to 6500, which has only one active module. So 1300 should be enough for it. But we dont know if they are physically compatible, if it is possible to plug. I didnt find this power supply to be officially?

These messages are I am recieving on few ports only not on all port having IP Phone connected. I tried changing the phone to some other model but that also did not resolved my problem. Also I tried powering on the phone using power adapter but the issue still persist.
Client are not facing any issues due to this error, but still I would like know what can be the issue which is generating these logs.

I'm looking at provisioning a Catalyst 4500 with a WS-X4712-SFP+E module to allow for future 10Gb connectivity via 10Gb SFP+ interfaces. These cards are backwards compatible with standard 1Gb SFP interfaces but I'm wondering about the other way around; ie. can you populate these blades with 10Gb SFP+ interfaces when they connect to Catalysts with only 1Gb SFP interfaces at the other end?
The data sheets don't really explain this. It seems pointless getting 10Gb SFP+ interfaces for the 4500 when it's only 1Gb at the access layer end, but these access switches will be replaced in the near future (~12 months) and if the 10Gb SFP+ interfaces support connections at 1Gb speeds upfront, it would mean I could retain these interfaces when the access switches upgrade to 10Gb connectivity capabilities down the track. Does the 10Gb SFP+ interfaces are compatible with 1Gb SFP's or only other 10Gb SFP+ interfaces?

Created two 6509s as VSS with just one 10gb connection?I know it is recommended to use both the 10gb connections on the sup-720 from below configuration guide
"
Information about VSL Topology
#
A VSS contains two chassis that communicate using the VSL, which is a special port group. Configure both of the 10-Gigabit Ethernet ports on the supervisor engines as VSL ports.
"
But will the VSS come up if I use just the one?

I have two 3750 stacks that are currently connected using two1GB fiber connections in an etherchannel. I now added new switches to each stack with 10GB modules in them. We would like to bring up the 10GB connection, but still have one of the 1GB lines as a backup, or even the whole etherchannel. Is there a way for us to make the 10GB the main and the 1GB the standby?

For a simple 4x sites design for backup consolidation (3x sites connected to one central site), does the design in the attached JPEG make sense and is the configuration achievable using the specified parts?
Brief Explanation:
- Each site is to have servers with 2x 10Gb/s Ethernet (both teamed/bonded/etc) and one NIC on each of the 2x switches in the site (if possible). Each site will also have 2x Cisco Nexus 5596UP Switch (though the P version may be used instead of the UP).
- Two of the sites are within 10KM of the central site
- The last site is about 35KM from the central site
- It is required to have a minimum bandwidth of 10Gb/s between any site and the central site
- I have specified 10Gb/s LW SFP+ and 10Gb/s LW SFP+ (for the 2x 10KM and 1x 35KM sites)
- are there any special licenses needed?
- as asked before, can such a "simple" design work as-is?
- what sort of single-mode fiber would fit the bill (especially for the 40KM link) - 9nm?

I have configured about 20 of these switches now, and notice in the port listings a TE1/1//1 TE1/1/2 and GI1/1/1 GI1/1/2 uplink port. There are only two uplink SFP+ ports. I now have a reason to install with a 1Gb uplink to the Core. I am using a GLC-LH module at each end. I did configure the TE1/1/1 port for the uplink. Does not work though..Do I need to configure the two GI1/1/1 and 1/1/2 ports for uplink, remove the TE configuration for the uplink to work? Using the UNIVERSAL code with a LANBase license.

We are trying to connect 2 nexus 5558UP (5.1.(3)N1(1)) with 10G-SFP+-LR interfaces. The interfaces are not genuine cisco's (smartoptics) but as far as we can tell, they are accepted by the hardware. If we take a look at the optical levels, we can see that the switches can see eachother (double-checked by bringing down one interface to see if optical levels really disappears) on optical level, well within limits. I found a notice about changing debounce timers but this doesn't work, setting it to 0 or 1000 doesn't make a difference. Copies of the different show int commands can be found at the end of this text.

Any experience with bundling a 10GB interface on a 3750G-16TD-S with a WS-C3750X-48T-S with a 10GB interface. I have worked with 5 different TAC engineers and so far I have not gotten an answer on why the switch will not let me bundle the 10GB with another 10GB interface.
Same switch Stack – not a cross stack.
Tried every configuration possible with no luck. I originally thought it might be the stack-ring speed – I corrected that today and it is running at 32GB –
The only thing I can think of now is it might be a hardware limitation on the 3750G-16TD-S ?
Q. What performance of the 10 Gigabit Ethernet port on the Cisco Catalyst WS-C3750G-16TD switches?
A. The Ten Gigabit Ethernet uplink on the Cisco Catalyst WS-C3750G-16TD switches is 1.25:1 oversubscribed and provides maximum throughput of 8Gb/s. –

specifying Cisco devices and I've made an error.I have 2 Catalyst 2960S switches (C2960S-24PS-L).Based on this snippet of web copy from the Cisco website:What's new for the Cisco Catalyst 2960-S Series Switches with LAN Base Software: # 10 and 1 Gigabit Ethernet uplink flexibility with Small Form-Factor Pluggable Plus (SFP+), providing business continuity and fast transition to 10 Gigabit Ethernet I bought a cable assembly "SFP-H10GB-CU3M" (3 meter copper twinax cable with 10GB SFPs on each end). Unfortunately, it appears after more careful reasearch that my specific model 2960S's are not directly compatible. , can I force these 10GB SFPs down to 1GB and get them to work with my switches or do I need to return and repurchase?

We currently have 2 6509s with redundant Sup720-3b's and PFC3B daughter cards which are connected together over dark fibre using the Gb fibre connectivity built into the supervisors.
The requirement is to upgrade this connection to 10Gb as inexpensively as possible.
Do I need to purchase new supervisors in order to do this properly or can I use a separate 10Gbe module (we have a spare slot), i.e. can I get away without using the connectivity built into the supervisors?
The other idea I had was putting a couple of 3750-X switches at each end to sit in front of the 6509s and provide the 10Gb connectivity between sites. I could then use the existing Gb uplinks on the supervisors whilst also providing connectivity for some devices that currently connect to the 6509s but could just as well connect here.

we have just purchased a few 3750x's that we intend to add to our 3750g stacks. We've purchased the 10gb uplink modules, C3kx-nm-10gt, but when they are installed they are not appearing in the switches web gui nor can you configure them correctly. If we upgrade a 3750x to 15.0.1 they seem to work fine. All of our current 3750g's are running 12.2(58)SE2 IPBASE so we don't really want to have to upgrade them all to 15.0.1
Are we missing something or do the 10gb modules only work properly with ios 15.0.1?

I have 3560's in my current environment, operating in the core/distro/access layers. The switches are in a star configuration, performs only layer 2 switching, and utilizes copper (no plans on moving to fiber).
With a fairly limited budget, I've been contemplating on upgrading the central node to a stacked 3750X to eliminate that single point of failure, and trunk the rest of the 3560's to the stacked switch. I wanted to be sure that the 3750X switches will be right for my environment (90-100 hosts), and if what I explained above is a good solution.
I'm also looking like to upgrade 6-7 of my servers (and SAN) with 10GB network cards. Do the ports on the 3750X have port densities capable of 10GB? If not, what switches provide that capability?

Config : Stack-power in power-sharing mode/strict With CLI on the switch : All the power supply's and stack-power details, prio look OK.
Only: LMS prime /inventory/cisco-view/configure/power supply status result : some power supply's are marked as disabled.with the command > power supply 2 slot a off/on I manage to get the status back to "normal", but after a few hours some power supply's are again marked as "disabled".
