I have strange problem with 1800 router , I can't see any debug messaging , the ping from PC to this router is Ok , but no icmp debug appears , even I enable "debug ip icmp " the version of router is : C181X Software (C181X-ADVENTERPRISEK9-M), Version 12.4(6)T6
I'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.
I 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 ?
My Nexus is a 5548-UP model, NX-OS version : 5.1(3)N2(1b)
I try to debug an OSPF and an ICMP problem using the debug ip ospf command and the debug icmp command but not output appear on the terminal. As the switch is remote, I entered the terminal monitor command of course.
SG01NX01# terminal monitor SG01NX01# debug ip ospf 1 packets SG01NX01# show debug
I'm testing debug spanning-tree functions in a lab, hardware is Cisco 6509 with SUP-720-3B and WS-X6748-SFP, IOS is 12.2.33.SXJ. It's a root in some vlan's, stp mode is rapid-pvst.I wanted to see how spanning-tree is working (STP packets dump, etc.), and entered following commands on 6509: [code]
Then, I turned the "debug spanning-tree all" mode on. Now, I expect to see BPDU packets from Cisco, and other spanning tree events in logs on syslog server, or in log buffer, but I don't get anyting there. Except, there're some lines in log (they repeat very rare): [code]
I'm using "WS-C4948(12.2(54)SG)+PWR-C49-300AC/2". The following message are logged in the system log, but it was to check the status with the show command and status LED, but there was no abnormality. I thought the power supply has failed, but I seem different.

I've taken 2 4507's fresh out of the box running CAT4500E-ENTSERVICESK9-MZ.122-53.SG2.BIN which was upgraded from CAT4500E-IPBASEK9-MZ.122-53.SG2.BIN
I'm getting constant %C4K_S2W-4-WRITECALENDARERR: Calendar write operation Failed errors on the console. I was also getting them on the original IOS version.
Anything I've seen say's to ignore them but their very frequent filling up the logs.
There's very little return on google and no bugs to report on Cisco?
Have a small stack of two 3750 routers. Get the following error message every few secounds:
%STACKMGR-4-STACK_LINK_CHANGE: Stack Port 1 Switch 1 has changed to state DOWN %STACKMGR-4-STACK_LINK_CHANGE: Stack Port 1 Switch 1 has changed to state UP
Now I replaced the stacking cables but no joy. It was ok for an hr or so but then the error messages popped up again. Also random links on this stack back to access layer user switches have been going up and down randomly. So I have decided to take the next step and upgrade the IOS.
Although when I try and copy a new IOS I get the following error:
%Error writing flash:/c3750-ipservicesk9-mz.122-55.SE6.bin (No space left on device)
Seems this image is 130MB while the image that is currently on it is 74MB and free space is 54MB. How do I get the image onto the router? If I delete the current image from flash will that cause the router to stop functioning?
Also I noticed there seems to be more than one flash directory. See below:
copy tftp: ? flash1: Copy to flash1: file system flash2: Copy to flash2: file system flash: Copy to flash: file system null: Copy to null: file system nvram: Copy to nvram: file system running-config Update (merge with) current system configuration startup-config Copy to startup configuration system: Copy to system: file system vb: Copy to vb: file system
The current router image seems to be in flash1 and flash 2 also. Could I delete the image from flash1. Upload it there and then boot the router from flash1?
It never happened before and the configuration did not change. The only thing that happened, the WAN connection (point-to-point to a Cisco 3845) went down and the router rebooted while the WAN was down. When the WAN came up again, everything went fine, until about an hour later and the first occurrence of this mentioned log.This 3945 does establish an IPSec tunnel with its peer (the 3845) and all the traffic, including OSPF, is going through the tunnel.
my MSFC2 sent this strange log message. %DATACORRUPTION-SP-1-DATAINCONSISTENCY: copy error, The error message decoder tool says: "NOT FOUND". The level is "alert".
We are running a small network business and as funs of ciscos we own a some of the 4948s.We are facing an issue with couple of them as we get the below error message
C4K_CHASSIS-3-INSUFFICIENTPOWERSUPPLIESDETECTED:Insufficient power supplies present for specified configuration
First thought to replace the power supply didn't actually work as we did that with no result.Power consumption is not an issue as well because all other 4948s work fine with 1 power supply (forgot to mention is 1 power supply in all of them).
I recently upgraded my network to have two 3750x core, one interface on the Cisco is connecting to a Net gear switch via a fiber converter. I am keep getting the vlan flapping error message in my log as below.
003396: Sep 17 01:46:16.328: %SW_MATM-4-MACFLAP_NOTIF: Host 5c0e.8ba7.0a5c in vlan 2 is flapping between port Gi2/0/15 and port Gi2/0/13 003397: Sep 17 01:46:19.843: %SW_MATM-4-MACFLAP_NOTIF: Host 5c0e.8ba7.0a5c in vlan 2 is flapping between port Gi2/0/15 and port Gi2/0/13 003400: Sep 17 01:49:58.769: %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet2/0/17, changed state to down [Code] .....
After my research i think this is a looping issue but I'm unsure how to address 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 recently upgraded a few 2960 switches to 15.0(1)SE, and while they are working fine, I did notice a strange syslog message upon boot-up that wasn't previously there. [code] I did some cursory searching via google but nothing useful presented itself.
I am receiving this error after connecting a copper adapter on a GBIC blade in a 6509. Here are the results from the show Interface. I am waiting to confirm the device on the other side settings but as far as I see I get UP and Up for protocol and line respectively.

I have a stack of 3750x switches running 15.0 (2) SE2 IOS. When I reload the switch stack, I am seeing the following message in the logs: IPv6 user port trust TCAM write failed.
I have a pair of 3750E-24PD-S stacked together, it seems after stacked together the stacked switch always flood the console screen with these messages which are not true: [code] Switch-2 is the stack member, Switch-1 is the stack master. The RPS fan failed refers to RPS2300 or the internal power supply of 3750E? Even when I turned on the RPS2300 the stacked switch still display the messages. Also I have two RPS2300 serving stack master and stack member respectively both RPS2300 were switched off why the messages only refer to Switch-2 and not Switch-1? [code]
My 2811 sip gateway send invite to my ITSP server with incorrect IP address in Contact section. It uses the internal ip address instead of using the public ip. As results, the re-invite sent back from ITSP sip server cannot be recieve. Could some tell how to change the ip address in Contact section of the invite message.
i have major problem with two new Small Business 300 Series switches.Everytime i try to save the running config i get a GUI error message: "Another copy process is active, please try again later."It's also not possible to re-flash the firmware because the GUI stops responding.I have also tried to do this via console access and this produces a "the copy utility is occupied by another user" error message.-> so this is not a browser based problem.My first thought was that the switch (SG 300-28) is faulty so i unpacked the next new one (SF 300)and got the same error messages!Then i had a 2 hour webex support session with the Cisco Small Business Support and they did not found a reason for this behavior.Both switches are working normally, you can configure them, but after a reboot they are back to factory default again There is no possibilty for copy running config to startup config and it's also not possible to flash the firmware.(Web GUI & Console). tell me if this is a fundamental problem of the 300 Series?
I need 10gigbit uplink for this switch. What are the other devices that i need order along with this device.And what is the diff between X2-10GB-LR= and CVR-X2-SFP.if i take CVR-X2-SFP, in future how can i upgrade from one gig to 10 gig?for current use i need 10gig support required. so what are all the other devices that i need to order.Fiber multimode and distance 15Mt only.
