View 7 Replies View RelatedCisco Switching/Routing :: How To Debug A TCAM Switch On 877W
Feb 24, 2012I've created a BVI2 where I bridged dot11 0.2 and vlan2 in order to have wired and wireless clients in the same vlan.Some wired client are not reachable from the lan. Wireless clients have no pbl in reaching each other.Monitoring a MAC address that is supposed to be behind the FA2 I have noticed that it moves to vlan2 when in fact it should be behind the FA2.Of course when "show mac-address-table" says it is behind Fa2 the ping to that MAC address works whereas when the TCAM reports it is behind vlan2 it doesn't. Once the MAC address is behind the vlan2 if I clear the mac-address-table and that mac-address is still put behinf Fa2 then the pings works again, sometime I have to perform twice the clear command before the MAC address goes back to the right location.I'd like to understand why the router moves that MAC address from Fa2 to vlan2 and that's the reason for my question in the subject.I don't have any problems for port Fa0 and Fa1."Show int fa2" doesn't show any problem/errors or the likes.BTW even if I force that MAC address to be statically behind FA2 the ping works fine but then stops and if I do "show mac-add" the static entry for it is still there... so looks like there us something that overrides that static entry. If clear everything and I have the mac-address be behind Fa2 then everything starts to work again. I used Fa3 instead of Fa2 and I get the same results.

Cisco Switching/Routing :: 3750E Debug Causes Switch To Crash And Reload
May 3, 2013I am not able to find the exact bug for Cisco 3750E stack - Debug Exception (Could be NULL pointer dereference) Exception (0x2000) error. Closest i can find is CSCsa72400 which only affects ver 12.2(20)SE4.All the stacks (3 switches) are running 12.2(50)SE3, It appears that the switch 1 crashed and reloaded. My hunch is its software but i cant find any related bugs. It could be hardware issue as well ?

Cisco Switching/Routing :: CoPP Logging On A 6500
Mar 19, 2013I 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?

Oct 10, 2012As 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.

Sep 19, 2012We 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

Cisco Switching/Routing :: 3560 - Enable Informational Logging And Get All Messages?
May 9, 2012I 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.

Sep 29, 2011I 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"
!

Cisco Switching/Routing :: Not Logging All Levels Of Sylog Messages From Core Switch 4503
Apr 23, 2012We 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

1) Is there any more configurations required for getting all traffic related messages, (i mean all possible messages - upto level 7 - debugging)?
Cisco Switching/Routing :: 2811 Disable Audit-trail For Icmp Packets In CBAC Logging
Mar 23, 2013I 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.

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) ?
