EEM on port error-disable due to UDLD

I would like to ask from the EEM community for some assistance in regards to crafting an EEM script for an ME-3800X. We have one or two appliances whereby the only uplink (TenGigabitEthernet0/1 and/or TenGigabitEthernet0/2) goes into error-disable and caused by UDLD. What I am looking for is a script to do the following:
1. If the ports TenGigabitEthernet0/1 and/or TenGigabitEthernet0/2 goes into error-disable caused by UDLD or link-flap then disable the port, wait for 5 seconds, enable the port;
2. Wait for 15 seconds and send an email.
I only want this EEM to work on the TenGigabitEthernet interfaces and I do not want the EEM script to do this on the access ports.
Error-disable recovery is a global option and there's no option to limit on a per-interface level.
Thank you in advance.

Thanks for responding, Joe.
We were not able to take down the error messages but I believe they error messages could be:
%UDLD-4-UDLD_PORT_DISABLED: UDLD disabled interface Te0/2, unidirectional link detected
%PM-4-ERR_DISABLE: udld error detected on Te0/2, putting Te0/2 in err-disable state
Could an EEM script be created when an error message or an event of "unidirectional link detected" occurs, do the following:
1. In privilege mode, issue the command "udld reset".
2. Wait for 30 seconds and then send an email.
Thanks for your assistance and support, Joe.

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.

Can you send the output of

show lldp dcbx interface ethernet 1/3
a workaround may be to disable lldp on both sides on these physical interfaces

Error disable due to loopback

Hi,
We have a campus network. A student's hostel room port that is connected to a 2960 switch get error-disabled time and again and it shows the reason being "loopback".
From switch patch panel to user's LAN port in room , we have tested the connectivity through cable tester and it is found to be proper.
He has changed his LAN cable also, what can be the exact reasons causing this problem

Thanks for the output to the command "sh version".
Look at the uptime of the switch. Because of this the output to the "loopback_error_2960" is totally useless. Why? If there was any line errors which can determine if there was a cabling issue, a NIC card issue or something more sinister, then there's only 4-days worth of data. Not much to run with.
The IOS is very, very old.
Currently, the only thing I can think of is remove the configuration of setting the speed to the port to 10 Mbps. (I don't see the benefit of punishing students by slowing down their network speed.) Once the port is running auto speed/auto duplex, wait for approximately 30 minutes and run a TDR on the port. Even better if you can move the cable to the GigabitEthernet port and run the TDR there so you'll get a better picture of all the pairs.
Another thing, post the output to the command "sh post".

FI's uplink ports Error Disabled on ENM loop

Hi,
I have two UCS6120XP FIs connected to a Cat2948G-GE-TX switch via port 1/3 on each FI. One port on the Cat2948G-GE-TX acts as the uplink port and is connected to the LAN. All ports of the Cat2948G-GE-TX are in VLAN 1 to allow all connected devices to reach the Gateway via the LAN uplink port.
Now after a while both ports 1/3 on the FIs get error disabled on ENM loop.
'show cdp neighbor' on the Cat2k shows FIs hanging off of 2/45 & 2/46. The management ports of both FIs are connected to ports 2/1 and 2/2 of the
Cat2948G-GE-TX as well, as are some other devices.
I'd like to keep both FI uplink ports enabled for failover scenarios - how can I achieve that w/o the ports getting error-disabled?
Thanks,
Matthias

Hi,
The reload was to test the loss of a FI prior to going into the production environment. A disassociate/reassociate of a SP made no difference.
I plan to upgrade to V2.2(1D) and re-test again tomorrow.

New Trunking port Error Disabled on Nexus 5000

I configured my Nexus 5000 ports as so
Int Eth1000/1/48
switchport mode trunk
switchport trunk allowed vlan 8
speed 1000
channel-group 7 mode active
int Po7
switchport mode trunk
switchport trunk allowed vlan 8
vpc7
speed 1000
I configured my 3650 as so:
int Gig0/23
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 8
switchport mode trunk
speed 1000
channel-group 1 mode active
Port channel 1
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 8
switchport mode trunk
speed 1000
Both of these ports are connected Int Eth1000/1/48 and int Gig0/23. Int Eth1000/1/48 shut down and when I checked the logs on the N5K it said for the port ErrorDisabled REASON BPDUguard. I did not configure bpdufilter or bpduguard on either side. What is causing it?
I found 3 other ports the have bpdufilter on them would that be it?
Since the 3560 is an older switch how can I also ensure it get demoted to not be root bridge or secondary root bridge?

Hi,
1- You tried to bundle GE and E interfaces with LACP on both switch but you did not mention the other bundle members, however, it looks the etherchannel did not comes up and interfaces work separately.
As a result, STP has prevented bridging loop and put one of them in errdisable state. I think you must check your etherchannel configuration.
2- you can use "spanning-tree vlan <> priority 61400" on 3560 switch to make sure it won't be a root bridge.

I looked into the error and would suggest opening a TAC case so our engineering team can look into this error. You can open a case using the supportforum as well to turn the thread into a case.
Sorry to not be able to help more, but looks like our internal team needs to look into this further.

UDLD Detection & Error Disable On Cat 6513

Hi
We have a problem with an etherchannel trunk between 2 Cat 6513's. The etherchannel is 8Gb split across 2 Copper 10/100/1000Mb 16 port cards in each chassis. The trunk uses ports 13 - 16 on slot 5 in one chassis to 13 - 16 on slot 5 in the other chassis and 13 - 16 on slot 6 in one chassis to 13 - 16 in slot 6 on the other chassis.
We appear to have had a UDLD Detection which error disabled all 4 of the links from slot 6 to slot 6 at the same time. IE ports 13 - 16 on slot 6 of both chassis went into error disabled state.
Could this be a ASIC hardware problem on one of the cards? If so, how do we establish which end of the trunk the problem exists? All other connections on these slot 6 cards are working fine.

UDLD is a protocol that discovers if communication over a link is one-way only, and therefore partially broken. A damaged fiber cable or other cabling/port issue could cause this one-way only communication. Spanning tree loops can occur with this problem. UDLD allows the port to detect a unidirectional link, and can be configured to put a port in errDisable state when it detects this condition.

Vfc error disabled because of Ethernet port down?

We are building a new datacenter and is starting to set up the SAN.
This small DC consist of 2 Nexus 5596UP, a Compellent SAN and 2 Dell M1000e cassis with blade servers.
naive FC part in Nexus has been easy to set up but we have problems with the FCOE setup.
Since the blades are not installed yet none of the Ethernet ports are up. As soon as we bind an ethernet port to a vfc the vfc goes to error disable with this message:
%PORT-2-IF_DOWN_ERROR_DISABLED: %$VSAN 1900%$ Interface vfc101 is down (Error disabled)

Do the vfc go error disable because the ethernet interface being down? I was under the impression it should just go "down"

Campus Manager report - Ports in error Disabled state

Hi,
I have LMS 3.2 and I wonder how Campus Manager collects information from the switch to generate a report of discrepancies, namely a report of "Ports in Error Disabled state"??
I find that I have ports in errDisabled state but Campus Manger doesn´t show this information in "Ports in Error Dissabled state" report. What could be the problem?
Thanks.

Hi,
Campus Manager do snmpwalk on the ciscoErrDisableMIB to get the status of the error disabled ports.

Error disabled ports

I have a 3550 switch that gets a error-disabled copper ports. There is no errors ont the port. What else would cause it to be disabled?

Although there is no error on the port , there should be an error message in the log that should tell you the reason why the port got error disabled like port security violation , loopback detection , etherchannel misconfig etc.
You can enable errordisable recovery for all different causes by setting a timer. What happens is once this timer expires , the port is brough out of error dsiabled state.
Here are some of the useful commands.
D-C3550-2A(config)#errdisable ?
detect Error disable detection
recovery Error disable recovery
D-C3550-2A(config)#errdisable recovery ?
cause Enable error disable recovery for application
interval Error disable recovery timer value
Hope this helps.
