Cisco Switching/Routing :: 891 - Get Rid Of Logging Trap Debugging?
Oct 10, 2012
As part of troubleshooting a seperate issue, somebody on my 891 router had set logging trap debugging which shows as a line in sh run just above the access-lists. There is no syslog server however so I'd like to remove this entry, however when I do no logging trap debugging I end up with a no logging trap entry replacing the previous logging trap debugging entry. Is there away to be rid of this entry? I tried no no logging trap but of course that's an invalid command.

Doing systems work now, but today I am busy troubleshooting a site-to-site VPN endpoint on an ASA.
I find it hard to believe, but I've spent over an hour just trying to login and get some debugging info on the key exchange, etc. It seems almost impossible. I've tried "term mon", "debug crypto isakmp", "logging console", "debug crypto ipsec", and a gazillion other things.
Can't I just see the debug info for the site-to site VPN?

I have an issue with a Cisco 857w. When I connect on via SDM I get a message saying "SDM has detected enabled debugs on the router. Because debugs degrade the performance of the router and of SDM, it is recommended that they be disabled". I've connected onto the router via telnet and ran the show debug command which indicates that dot11 debugging is on and when I run the command no debugging all it turns it off. I then do a copy run start and reboot the router and it comes back on. how I permanently disable it?

I am looking for a way to see packets that are matched on certain ACLs in a CoPP policy map. I have read that it is not a good thing to add the log keyword at the end of an ACL when using that ACL for CoPP. I initially tried to use a logging policy map but the 6500 12.2sx doesn't support this.
how I can see source/destination IP for a certain class in a CoPP policy map?

We recently replaced our core switch from a non-cisco vendor with a Nexus 7010. With our old core switch, I had the ability to log changes to the ARP table. So if there was a dhcp conflict or a vMotion event, it would show up in the "show log" output. I've not found a way to do that with the Nexus switch - or at least no way to view the log. I have the command: logging level arp 6

i can't configure "logging event spanning-tree" on a specific port under IOS 12.2.(58) SE2 (all other "logging events" are possible), under 12.2 (55) it is possible. Is it now a known bug or a default value?

I have a situation in which I want to log a specific message (informational - 6 level), but don't want to enable informational logging and get all the messages that come with it. Is there a feature in IOS, 3560 12.2(25r)SEE4, similar to the 'logging lists' feature on the ASA that allows you to specify logs that you want to capture without having to change your logging level? I didn't want to have to write an EEM applet for this, but if that's the only way, I'd consider it.

logging buffered 4096 warnings The above causes router to log all the events with severity level 4 or below in buffer.What about logging console warnings command?will the above command cause router to send log messages with severity level 4( warnings severity level) to console only or will the router send all the log messages with severity level 4 or below to console ?

I found a bug in Embedded Event Manager, on Catalyst 4500-E platform with supervisor V-10GE, on various IOS releases (in particular 12.2-50-SG IP BASE w/o crypto, 12.2-54-SG1 IP BASE w/o crypto, but also other releases included latest 15.0-2-SG1 ENTERPRISE SERVICES SSH).The problem is that when you set up a EEM applet that monitors syslog pattern matching, and you also configure remote host logging *with* the option "sequence-num-session", when the match occurs, the switch reboots with message:
Sw (sometimes prints a number instead)
VECTOR D00
and in some cases performs a second reboot with message:
VECTOR 0
DOUBLE FAULT
The reload reason message is:
System returned to ROM by abort at PC 0x0
The problem does *not* occur if remote logging has not the option "sequence-num-session". I verified this behavior on various configurations (included our production 130K long *and* factory defaults after erase startup-config).The configuration statements that cause reload are, for expample:
event manager applet prova
event syslog pattern %SYS-5-CONFIG_I
action 1.0 puts "configurazione modificata"
!
logging host 172.30.10.1 sequence-num-session

I'm looking to configure a syslog server for all of my cisco device logging. I've had a look at CNA and can't find any options to define a syslog server for my switches.
What's the best way to define a syslog server and the severity of the notifications? Also, i'm looking to clear all previous Syste mmessages fon my devices?

I'm trying to view the logs from a Cisco 857W router to a workstation running the Kiwi Syslog server. what I've done is the following:
Config term
Logging on
Logging source-interface BVI1
Logging Facility Local7 (or any other facility you want to allocate for this router.)
Logging [IP Address or Hostname of machine running Kiwi Syslog Server]
End
I see noting on the syslog server. Although I can see the log information on the router Also is there a command to stop the logging from generating or is this on by default.

I have a WS-C3560X-24 and attached to that are some 9 acces switches, for some weeks now my 3560 reboots some time what couse that the other 9 switches are down for some minuts as well and i dont want this of course. the reboot happens at random times and some times one week not and then like yesterday afternoon it rebooted again.
when i check the Flash directory there is no crash file and when i look at the logging its clean and just shows the startup. it's not the powersuply it's redundend and more L3 switches are attached to this power source and they dont reboot.

We have a design of two 6509 running in a VSS with dual supervisor each having fthree 10/100/1000mb etherner modules. We have diagnosed a wierd problem that none of the switchports in module 1 and 2 on either switches are having layer2/layer 3 connectivity.
Tried everything from changing the cables to changing the end device but no luck with it.
Module results show pass and no errors in the logging.

We had a core switch(4503) in our environment and recently we tried to enable syslog in the switch. But the syslog server doesnt receives all the configured level messages from the switch. Following is the only message getting in syslog server after the configuration change in switch.
%SYS-5-CONFIG_I: Configured from console by CWLMS onvty1
(No Traffic related messages like acl deny traffic, spanning tree events etc are getting to syslog server as well as log buffer of the switch)
Following are the logging configuration for the core switch
logging monitor informational
logging facility syslog
logging source-interface Vlan44
[Code]....
1) Is there any more configurations required for getting all traffic related messages, (i mean all possible messages - upto level 7 - debugging)?

I have a cisco 2811 router set up as a nat/firewall gateway for my network. I've configured it for CBAC on using ip inspect and an access list.What I want is to use audit-trail to record network traffic (which means sending syslog messages to a server) concerning established sessions from my own network to locations in the outside. If i configure this using ip inspect audit-trail and no ip inspect alert-off, the configuration looks like this: [code] which works just fine, but there is the matter of icmp packets.
Since i use polling software that needs to check some machines in the outside part of the network, it is only natural that several icmp sessions are established through the Inspection Rule per minute. The problem is that since these sessions are recorded along with everything else, my syslogs are flooded with these (since i am using logging trap informational) to the point that more messages are generated about icmp than all other traffic combined, especially in non-working hours.What I am asking is a way for the audit-trail to be selecively disabled for icmp, so that the outgoing (echo) &incoming (echo reply) sessions can be established without generating syslog messages.

I'm encountering what I think is an issue on logging system on FW ASA 5520 - Asa Version 8.4(2), ASDM version 6.4(5). When I disabled the logging inside a rule from ASDM, or from console with the "log disable" option inside ACL, If I check in ASDM logging real time window I continue to see all the entry related to disabled rules. This is a correct behaviour about ASA logging ? How I can "hide" the entry related to disabled rules (this is what I need for troubleshooting purposes) ?

We're having some numbers ported over to us and we'd like to verify that we are in fact receiving all of the numbers at our SIP gateway. Since we have been getting more and more activity on this router, I'm becoming more concerned about using certain debug's for fear that the router maxes out CPU and drops.
What the best debug command would give me this information with minimal impact on CPU? In the past I've used 'debug ccapi inout' and a couple of others similar to that. With so much activity though sometimes it bombs the router. Also I am logging to the console directly, maybe there is a better method with less CPU impact. I just don't want to have to go back and forth to look for stuff 50 times either if I write out to a file or something, it could work though I suppose.
