Cisco Switching/Routing :: SW3750 - Voltage Low Alarm In Transceiver
Jun 18, 2012
I have the follow error in a SW3750:
%SFF8472-5-THRESHOLD_VIOLATION: Te2/0/1: Voltage low alarm; Operating value: 0.00 V, Threshold value: 3.07 V.
I used the command:
#sho interfaces transceiver
If device is externally calibrated, only calibrated values are printed.
++ : high alarm, + : high warning, - : low warning, -- : low alarm.
NA or N/A: not applicable, Tx: transmit, Rx: receive.
I want to know how much minimum power required for swicth catalyst 3750.I want to know cause in my building place, the power in unstable so it make my switch corrupt/damage even i add power consistancy....
How much amount power to the ups and ups to switch?
I had a bad power surge yesterday that took out a 2960g switch and the APC UPS that it was connected too. when plugged in the fan comes on and the syst light stays amber and the rps, stat, duplex. and speed light stay lit and the port lights for ports 21-24 stay lit. plugging it into the console on boot I cant even see rommon, so i dont think its even booting. I would like to find a pinout and voltage guide for the connector comming off the power supply so I can check the voltages coming off the power supply to tell if it is a bad PSU or if it took out the main board.
I am getting alarms on Solarwind indicating interface down on "GigabitEthernet 4/7 - Gi4/d1" and "GigabitEthernet 4/8 - Gi4/d2" from our core switch 6509.Remote login to the switch does not show the interfaces when I do the "sh run" command. Now I am at site trying to identify and diagnose this fault.Looking at the numbering on the switch, it indicates to me the card where these alarms come from is from the 'intrusion dectection module'
how I may login and identify this interfaces and rectify these alarms.
We are looking to purchase some addidtional 48 port swithches for our network. Currently we have the following swtiches setup
2 of 3750 POE-24 (These two are stacked and have our servers plugged into them). Currently no SFP modules.
3 of 3560 POE-24 (These each have two 1000BASE-T SFP modules in them, with UTP connecting back to the 3750 switches above)
We are looking to get 2 of 48 port C2960S-48TS-L switches with two 1000BASE-T SFP modules in each that then will also connect back to the 3750 switches.
I had a few of question about this:
Will the cisco lite version (rather than the more expensive cisco base software) support the 1000BASE-T SFP modules?
The 1000BASE-T SFP modules, are they auto-config? Have you the link for commands we can use, if required?
We don't have budget for stack modules, apart from that would you recommend we change anything with the new setup?
When I insert the TwinGig Converter in a Catalyst 4900M you get the following error message: Failed to read transceiver serial eeprom on port Te2/1, try reinserting.This error is probably because the device expects 10Gig transceivers to be connected to the device not 1Gig.I used the TwinGig 4 module and 8 SFP ports are connected. But when i type in the the "hw-module module <slot> port-group <group> select gigabitethernet" the command is not available. [code]
I have a catalyst 4506 switch with one sup-engine WS-X45-SUP6 L-E, which consist of two X2-10GB-SR Transceiver( CISCO).IOS on the sup-engine is cat4500e-ipbase-mz.150-2.SG1.bin. IOS detected only one X2-10GB-SR Transceiver in Ten1/2. When I insert the X2-10GB-SR Transceiver in Ten1/1
C4K_GLMMAN-3-X2PLUGGABLESEEPROMREADFAILED: Failed to read seeprom on port Te1/1. Reinsert X2 m
But the problem is i need two X2-10GB-SR Transceiver for Uplink.
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 want to connect a Cisco small business switch (sf302-8) to a Cisco catalyst 2960S over a multi mode fiber. The transceiver I am using in the catalyst is a GLC-SX-MM. I presume in the SF302, I will have to use a MGBSX1. My question is "are these transceiver compatible with each other and if not, is there a transceiver that will suit both pieces of hardware?
My Dir-615 stopped working some weeks ago and I switched to another router until I had time to look at it. Tonight I checked the ps voltage and it read exactly +5v but just for a test I tried another 5v ps (which tested a little higher) and it worked. The ps that works reads about link +7vdc. Before this the power light came on with the occasional blink but I could't connect.
I would like add an alarm to LMS when a power supply of some device goes down. For instance, when the power supply fails LMS send an email or something like that.
We are having Cisco 7206VXR with NPEG2 and the IOS c7200p-spservicesk9-mz.124-15.T10.bin.,PA-MC-STM-1SMI is connected to 3rd Slot of the Chassis. The Links terminated on the SMI are working fine and we are not getting any Error Messages on Chassis regarding the this SMI.
But here we have Amber LED Glowing on ALARM LED of the SMI Card.
As per the below Link: URL This means Loss of Signal/Frame. ##Table 1-5 PA-MC-STM-1 LEDs #LED Label #Color #State [Code]....
On Cisco ACS 5.2.0.26 Patch 10, I got this system alarm:Incremental backup is not configured. Configuring incremental backup is necessary to make the database purge successful. This will be useful to avoid disk space issues. View database Size is 2.92GB and size it occupies on the harddisk is 2.91GB
In "Monitoring Configuration > System Operations > Data Management > Removal and Backup", we got this information: Database Purging:If database size exceeds 120 GB, a backup (if configured) and purge will be initiated. If database size exceeds 150 GB, a purge will be initiated.
Could View database size reach 120 GB ?I want to know how long will Cisco ACS works without problem and if I need to hurry to configure purge.
I have a Cisco asa 5510. I am doing attack a my firewall, using n map. I am seeing in the log the attack but i like that firewall send only alarm of attack by email . I have active email with warning and i received very much email.
I observed that graph show attack, but not ip of attacker, is possible that Cisco asa show the ip too ? The log show scanning with n map but not shunning IP and not send alarm. How i can send alarm ? The graph no show ip, it's possible show it.
We have a WAP 200 wireless G access point. It worked perfect before. About two weeks agao, we didn't change anything, it began to send empty alarm email every 10 minutes. We upgraded the software to newest version,restarted it several times. But till now, it still keep sending empaty alarm email.
I am using ISE 1.1.1.268 and WLC 7.2.111.3 and NAC agent version 4.9.1.6 on Windows 7 Client machines.
About once a day i get the error "ISE Alarm (WARNING): Dynamic Authorization Failed for Device".
The device it is referring to is my NAD, a WLC 5508 running 7.2.111.3
I have looked at the logs and I cannot see anything in the logs which corresponds to this message so that I can troubleshoot further. Maybe I can if I am enabling the correct logging level on the correct ISE component.
What are the components and the logging level that I should set to get some more detail about this error?
At the moment, I have only set debug logging on Active Directory. I have TRACE logging set on Posture, Run time AAA & prrt-JNI.
I do not want to enable too much debug logs, so what is the specific element that I should be debugging.
I thought debugging the posture element would be enough but when I look at the logs there is nothing there that relates to this message.
I have WS-C3750X-24T-S switch with C3KX-NM-1G and now i want to put a transceiver GLC-EX-SMD= in the switch SFP port, is this GLC-EX-SMD= compatable with that switch ?. i thoroughly check the product datasheet and compatible chart but their i don't have seen ?
There're more than twenty 6509VE running in the network. All of them has got 1GE or 10GE SFP / GBIC.However, when I tried "show int trans" in some of them, there's nothing shown:

Since a few days my WRT120N gives an audio alarm (beep) about every 10 secs. Cannot find how to overcome this or find the root cause. Installed new s/w version. H/W reset. Nothing works.
We have C7206VXR NPE-G2 platform with transceiver which support DOM.Could we monitor DOM tx/rx level statistic through snmp for 7206 platform?In CLI result of command "sh interf GigabitEthernet0/1 transceiver" give some information.We tried search for some MIB In "MIB locator" on cisco.com.
I am buying a Nexus 5K (N5K-C5548UP-FA) with the layer 3 card (N55-D160L3 - Nexus 5548 Layer 3 - Daughter Card).The switching capacity of it is 960 Gbps but I know I should expect less doing the Layer 3 function (it will only be used with static routing).What switching/routing capacity should I expect? How can I estimate it? What else should I consider?
we've had an issue with our network, we have 2 6509 connected with redundancy, which are connected with 2 x 4900 Switches, from which are connected to a ESX Chassis for visualization, the thing is that the ESX stopped working, and the 4900 switches, and the main core were suffering from overload, they hang on it very well, in order to stop the overload, one of the links to the ESX Chassis were disconnected from one of the 4900 switches. The CPU usage from the 4900 and the core(6509) went down below 40%, and then they started to migrate the virtual servers from the chassis to another 2 chassis that were added right after. They were actually working well, but suddenly the 6509 changed to the other supervisor after everything was OK. We were wondering what could have been the cause of this, maybe the virtual servers migrations, maybe the overload from the ESX ? We also had a few question, is there any need to reload the cores every few months as a planned task ? Because the cores have been up for more than 1 year. And also is there any kind of of tool to monitor the CPU status, or the status overall from the cores or the switches ?
I am facing an isssues with 7609 for LAN switching , based on LAN (VRRP/HSRP) feature.Actually we are having ES+ cards (on 7609) and we are using multiple groups(say 350 vrrp groups) running on the router . the routers are connected as router 1>>> mux(which is working as switches)>>> router2
my questing are
1. does their will be "multicast packets" (for VRRP/HSRP group) "from backup router to Master router", when in stable state( ie when Master and backup are already chosen) , or the packet from backup to master should be unicast.I know for sure, the packet from master to back is multicast packets denstination to Multicast IP packet and To MAC address.I am not sure but I think from backup to master it should be multicast
2. what is frequency of these packets( from backup to master)
3. As i have multiper group on a single interface ( we are using q-in-q), when the connectivity from router's is broken, then does all the groups will muticast their active roll in the lan sengment "at once" or it will be in a groups say 100 groups at once, and after few ms few 100's and sone ( as is on OSPF or RIP)
we are in between troubleshooting I hope we get the ans( Actul problem we are seeing in the router's that we have 2 ports on active routers and 2 ports on standby router , but we are not seeing muticast on 1 port on standby router where as all other 3 ports are seeing multicast packets) [code]
I would like to know if Catalyst WS-C3750G-48TS-E recognizes and understand Cisco VSS ( Virtual Switching System) . Is there a List available which tells us which Old Catalyst Switches or current switches understand Cisco VSS?
