GBIC-invalid error detected putting in err-disable state
I have a 3750x in which we installed a C3KX-SM-10G module if I look at the show switch service-modules it is showing connected. However as soon as I install the GLC-T transceiver in the gi1/1/2 in the module I get the following error "gbic-invalid error detected on Gi1/1/2, putting Gi1/1/2 in err-disable state" and when I look at the status for the interface it shows "err-disabled"
Any Ideas?hi,
as i know generally 10G modules and 1G modules are not compatible. you can check compatibility matrix -

LMS 4.2 - Err-disable port state
Hello,
I'm trying to figure it out how exactly LMS learns about ports in err-disable state? Which MIB or command is used?
I have two ME3400 switches with err-disabled ports but LMS shows only the ports of one of the them. Both switches are ME-3400-24TS-A
and have the same IOS version (12.2(53)SE). I'm sure data collection is running fine because it updates the other discrepancies.
What i have tried by now:
- did an SNMP walk from LMS on CISCO-ERR-DISABLED-MIB - no info found there on port status
- did an SNMP walk from LMS on CISCO-STACK-MIB - I know that this MIB contains object portAdditionalOperStatus (1.3.6.1.4.1.9.5.1.4.1.1.23) which shows the operational status of the ports, but it seems that ME3400 does not support it (although it supports CISCO-STACK-MIB), because I cannot see the SNMP reponse in the trace:
========================================================================
The following is a SNMP walk of device 192.168.6.89 starting from .1.3.6.1.4.1.9.5.1.4.1.1.23
SNMP Walk Output
.1.3.6.1.4.1.9.5.1.4.1.1.23
CISCO-STACK-MIB::portAdditionalOperStatus = No Such Object available on this agent at this OID
========================================================================
So how does LMS knows which ports are in err-disable state?
Kind regards,
VelinHello,
The OID that LMS uses for detecting the err-disabled state of the ports is 1.3.6.1.4.1.9.9.548.1.3.1.1.2 (cErrDisableIfStatusCause) from CISCO-ERR-DISABLE-MIB

Interfaces in port-channel keep err-disabling because of keepalives
Below is the current portchannel that I am having problems with. The interfaces on Switch A keep going into an error disabled state because they receive their own loopback. Cisco says to disable keepalives and that it will fix the problem, but I do not like the idea of disabling keepalives. Has anyone found a solution other than disabling keepalives? Notice that ios's are different, but am not convinced that this is the issue. Also one is PoE and the other isn't. Lastly, i found this article "Keepalives are sent on all interfaces by default in Cisco IOS Software Release 12.1EA-based software. In Cisco IOS Software Release 12.2SE-based software and later, keepalives are not sent by default on fiber and uplink interfaces". I would think trunked interfaces in a port-channel would be uplink interfaces and if this is true, it should be sending out keepalives anyway since i am running the 12.2SE based ios. Thanks for whatever input you may have.

Symptom:
An interface on a Catalyst switch is errordisabled after detecting a loopback.
Mar 7 03:20:40: %ETHCNTR-3-LOOP_BACK_DETECTED: Loop-back detected on
GigabitEthernet0/2. The port is forced to linkdown.

to administratively down
Mar 7 03:20:43: %LINEPROTO-5-UPDOWN: Line protocol on Interface
GigabitEthernet0/2, changed state to down
Conditions:
This might be seen on a Catalyst 2940, 2950, 2950-LRE, 2955, 2970, 3550, 3560
or 3750 switch running 12.1EA or 12.2SE based code.
Workaround:
Disable keepalives by using the no keepalive interface command. This
will prevent the port from being errdisabled, but it does not resolve the root
cause of the problem. Please see section below for more information.
Additional Information:
The problem occurs because the keepalive packet is looped back to the port that
sent the keepalive. There is a loop in the network. Although disabling the
keepalive will prevent the interface from being errdisabled, it will not remove
the loop.
The problem is aggravated if there are a large number of Topology Change
Notifications on the network. When a switch receives a BPDU with the Topology
Change bit set, the switch will fast age the MAC Address table. When this
happens, the number of flooded packets increases because the MAC Address table
is empty. -
Cisco 4506 switch in Err-disable mode
I have a Cisco 4506 switch and its 10 gig interface is in error disable mode.I tried Shut and no shut the port couple of times but it transits from up to down number of times and then to error-disable. Did anyone else encountered this issue before. kindly advise the solution for the same. thanks
Hi Shariq,
Can you post the output of the show interface status err-disable ? That output contains the reason for putting your port into err-disabled state.

A cable that is out of specification (either too long, the wrong type, or defective)
A bad network interface card (NIC) card (with physical problems or driver problems)
A port duplex misconfiguration

WAPs connected ports are becoming err-disabled.
Hi All,
I'm facing a strange issue. WAPs connected ports are becomming err-disabled with an attached error message. Not only a single WAP, All the WAPs connected to the 3750 are having the same issue. I have tried to identify which WAP is sending the BPDU and that inturn causing other WAP connected ports to be down.
I have 5 WAPs in that site; if I enable any WAPs connected port below logs messages are coming and that port is becomming err-disable.
Can anyone shed some light to troubleshoot this issue. Any help would be appreciated.

N5K err-disabled a port due to DCX-No ACK in 100 PDUs
I'm super new to Nexus, so I'm not really sure how to troubleshoot this. I did a quick search and found that this is related to DCBX TLVs in LLDP, which we apparently shouldn't be getting on a regular ethernet port. I'm pretty sure this is just a regular ethernet port. (Like I said, I'm pretty new to nexus. lol) I wonder if the following output indicates that we are receiving and sending DCBX TLVs in LLDP. If so, it sounds like the interface will go into err-disable state if the server stops sending ACK frames.

Thanks!Hi,
Per the display it the Server Adapter is doing LLDP DCBX negotiation.
If not needed, then you might want to check the Server adapter settings.

Gig port down/down (err-disabled) Reason: diagnostics
Hello,
Today I had a 2 ports on Cisco 6509 go into err-disabled state. Both ports show reason "diagnostics". I tried bouncing the interfaces and defaulting the interfaces. Any ideas? Thank you!

SF300-24PP switch causing err-disable on some other switch Uplinks
This is something that happened as I was setting up a couple of these PoE SF300 switches for IP cameras.
We wanted to save a little money so we purchased a few of these switches to daisy-chain onto a couple of our 4507s to provide PoE support for IP cameras that are coming in. But an odd thing happened when I set one up and connected it.
I set up the SF300 switch with all FE ports set to access and for VLAN 18 (our camera VLAN). I then configured a Portchannel (PO2) and assigned GE1 and GE2 to it. I defined the allowed VLANs 10,14,18 on the Port Channel Interface definition. I also created an SVI Interface VLAN definition for our management address (on VLAN 10) to be able to SSH into the switch once it's on the network.
I did most of this thru the CLI and not the GUI.
I saved the config (copy run start) and turned off the switch then deployed it in the IDF closet. I powered it up and connected the GE1&2 ports to 2 Gig ports in the 4507 defined with PO2 - both with MODE=ON.
Well, as I found out later, my config changes never got saved and the GE1&2 because trunk ports, so when I plugged them in, They started acting independently. At about the same time another switch we have in our network (that is daisy-chained off a 3750 - 1 trunk port) suddenly had it's uplink put into ERR_DISABLE mode (we also had this occur with another 2 switches with a very similar config - Daisy-Chain).
Now , how my config never got saved issue, is not at the forefront of my mind as much as how did a couple of switch uplinks in another building go into ERR-DISABLE.
I know that our 4507s run rapid per-vlan STP+ and that the SP300 only runs Rapid STP, but this is a real mystery to us. If anyone has any ideas for tracking this down, please reply.Hello James,
Welcome to the forums!
About the default settings. The switch comes with vlan1 as the default vlan for all traffic.
Here is a quick overview of the port settings
access - one vlan
trunk - multiple vlans
general - multiple vlans (had additional options)
When using the auto voice-vlan, you can have your port set as access for vlan 1 and when the switch see a phone connected, it will join the voice vlan also. This allow the ports to be dynamic. It is not necessary to do this. You can create all ports as trunk ports that are part of both your default vlan and your voice vlan.
The benifits of auto-voice vlan
-phones are discovered and joined to the vlan dynamically
-predetermined QoS settings
-security in that you can have your port set to access
This is a relatively basic overview.
As for the problem you are seeing. I would recommend that you check the firmware of the switch and upgrade if needed. While it may not have anything to do with the problem at hand, it will help prevent any future issues.
I would suggest disabling the Green Ethernet, which can be found under the port management section. If you continue to see the problem after that, I would recommend giving us a call at the support center. We will be able to look a little closer to what is happening.

WS-C6509-V-E VSS Pair: Random ports going into err-disabled due to udld error
We recently (a few months ago) put two 6509s into VSS mode and had many teething problems. One of the problems we had was random ports on switch 2 of the pair came up in err-disabled mode after a reboot. We somehow fixed them by combinations of shut/no shut, reseating or changing SFPs, etc.
Two days ago we saw half of the ports on one card were in err-disabled mode due to udld errors. We cannot find a way to bring them back up (tried udld resets, etc) and think it's really strange that it's a block of ports on the same card. Also it's strange since last time we had this problem it was on different cards (switch 2 as well though).
See below Te2/3/5-12 are in err-disabled mode. All other ports are fine. We highly doubt a physical problem with fibre and SFPs. Initially suspected the line card, but happened on different cards last time.
Is there some bug anyone is aware of? Software or physical issue?
Thanks in advance,
Paolo.

BPDU Guard without ERR-Disable
Hi Everyone,
I recently had an instance in one of my networks where a user plugged in a home router to our network. The router then started handing out incorrect IP addresses to clients.
I know I can use DHCP Snooping or BPDU guard to stop this happening again and we do have BPDU Guard running at other sites successfully. The problem has always been if we enable it in a new production network we might disable ports that have legitimate devices on the other end. For example someone is using a small switch to share a port between a PC and a printer.
Is there a way of turning on BPDU guard but without it putting ports into an Err-Disabled mode and just alerting in the logs instead?
Regards, DanielHi Leo,
Thanks for your input in the discussion. However I think you are misunderstanding why I am asking this question.
I WANT to enable BPDU guard on this network, I know its not a PIA and I am well aware of what it does and why it would be implemented.
The reason I am asking this question is because I need to transition from a network that doesn't have BPDU guard enabled to one that does. If i turn the feature on it will start disabling ports on switches and stop peoples workflow until it is resolved. The reason people have unidentified switches plugged into the network might be legitimate, but the way they got around their problem wasn't the best.
My goal is to find out where these rogue switches are, find out why they are there. Find an alternative way to connect these devices to the network by either purchasing new switches or running more cabling. This network does not have any onsite IT and therefor all this needs to be figured out remotely.
So the crux of the problem is. How to find STP devices that are plugged into my switches.

Can put condition in read statement for a particular fild please suggest?
hi i have a requirement as belo
1 ) i am reading a table with read statement now i want to read with one more condition like
where status<> Z
to add to this read statement as below can i add the above condition to the below statement?? let me know
how to check on this one more condition in below read statement
loop at itrecord1 into wa_Record
READ TABLE it_main INTO wa_inv_master WITH KEY
/' CUSIP = wa_record-primarykeyfield1 BINARY SEARCH.
here one more condition i need to put whilereading that where statu <>z which is best way todo
IF SY-SUBRC = 0.
APPEND wa_record TO itrecord1.
clear wa_record.
else.
APPEND wa_record TO itrecord2.
clear : wa_record.
ENDIF.
ENDLOOP.
so how to put the condition in above statment can put in the read statement as that is most convinient will that work?
regards
aroraHello arora.
You can restrict the READ to an internal table, using "n" conditions in WITH KEY statement.
Use:
READ TABLE it_main INTO wa_inv_master
WITH KEY cusip = wa_record-primarykeyfield1
field2 = wa_record-field2
fieldn = wa_record-fieldn
BINARY SEARCH.
Remember that if you want restrictions like ">=", "<=", "<" or "<", must use LOOP, not READ.
