Cisco Switching/Routing :: 6503 Sup-2T Unable To Get Into ROMmon
Apr 11, 2013
I have an issue with a customers 6503 with Sup-2T cards, where we are locked out of the console due to an authentication configuration error. So tried several times to get the card into rommon, with no success.
Checking through the various documents on CCO I dont find any reference to rommon on this card, but do find information on using the CMP to support the supervisor. I logged into the CMP but couldn't find a way from there to do a password reccovery either.So, is the `normal' IOS rommon/password recovery method supported.
I want to migrate a Cat 6503-E VSS to Cat 6509E VSS. We plan to use the same supervisor that we have on the Cat6503E, for minimizing the configuration change on the Doing this, the vss link will need to be changed, due to the fact that the supervisor slot will change with the Cat 6509, slot 5 instead of 1.
Question: is there a way to just change the vsl-link interface on a existing VSS ?
I have a cisco 6503 - e series switch which runs c6sup22-psv-mz.121-26.E4.bin. Both superviser engine and MSFC2 card run the same IOS image i guess. In my boot flash their is another image c6msfc2-jsv-mz.121-4.E1. o what is the difference between these images c6msfc2-jsv-mz.121-4.E1 and c6msfc-boot-mz.121-4.E1.
i'd like to configure OSPF on a Catalyst 6503 IOS 12.2.17.i habe an Gi1/9 with the ip address 192.168.97.30/24 and a VLAN 19 with the IP Address 192.168.19.0/24.I configured OSPF like this
router ospf 1 network 192.168.97.0 0.0.0.255 area 10.5.0.0 network 192.168.19.0 0.0.0.255 area 10.5.0.0
on the ospf peer is see that the adjaceny is established but i don't get the routes for the 192.168.19.0 network i checked the ip ospf interface vlan 19; i got ospf is not enabled on the interface then i tried to configure
I have a Cat6506. There were 2 Sup 720 in it for redundancy. They told me they had problems with this thing in the past needing to go out and reboot the machine. I need to go out periodically because it goes into ROMMON. I type boot and it comes back up. One time though neither one would reboot. I had to take a third one out there and reconfigure it. Now it is starting to do the same thing. One thing I did notice is they never connected it to an UPS. It is plugged strait into the wall with power going to two outlets. I am beginning to think there are spikes in the power occurring and this is sending it into ROMMON.
I upgraded four 3560E, 12.2(44) to 12.2(55)SEThree 3560 works fine, the last one stops after 17-18 seconds with a solid green LED. I cant get into ROMmon, the switch doesn't boot up. its like "dead but still alive"
My TS: 1: Removed all SFPs. 2: Reset PSU and fan modules. 3: Replace PSU and fan modules. 4: Try to get into ROMmon.(pushing mode button and break seq.) Startup LED:0-1 seconds: SYST: Amber RPS: Amber STAT: Green DUPLEX: Green SPEED: Green 1-17 seconds SYST: Blinking Green RPS: OFF STAT: OFF DUPLEX: OFF SPEED: OFF 18 s--> (only testet up to one hour) SYST: Solid Green RPS: OFF STAT: OFF DUPLEX: OFF SPEED: OFF
A working 3560EStartup LED information. If I compare a working switch with the faulty switch I can see about 18 seconds into bootingSYST change very fast from green to amber and continues with booting,this doesnt happened on the faulty switch (solid green 18 seconds). Pushing MODE button, doesn't get me in to ROMmon, this works for all the other switches.On a normal 3560 it takes around 40 seconds before I get in to ROMmon. With this faulty switch it stops after 18 seconds(solid green) and it doesnt respond.
Could not find a valid file in BOOT environment variable. BOOT variable can be set from IOS. To find currently setRom Monitor variables, type 'set' command.
Choosing a boot method, type 'confreg' command.rommon 1
I'm currently pursuing to take my CCNA and am currently studying for it, but have recently encountered a problem with one of my 1760 routers that I can not solve.Yesterday I went to boot up my router like normal, however when I went into hyperterminal I noticed the router was in Rommon mode. Thinking I could change the configuration registry, I tried to bypass the NVRAM by using confreg 0x2142. However this still causes the router to go into Rommon mode. I am getting an error that states that there is insufficient memory to load the IOS image. [code]
I have used the dir flash: command and can see the IOS image, and try to boot from it (boot flash:iosimagename) but it will still go back into rommon mode. I also just swapped the RAM from my other 1760 into this 1760 and it booted up and went into normal configuraiton mode without any issues. However, the other router now will not load it's IOS image and I get the exact same error.I'm at a loss here, and have searched to figure out where or how I can just wipe the router clean to try and start fresh, but cannot get out or Rommon mode. The only thing I can think of is that the RAM went bad since it wont boot up either machine.
I am facing a problem with a cisco 6509 that goes into rommon every time i restart. If i give the command
rommon 1> boot
it will pick up the IOS on the sup-bootdisk: or bootdisk: and boots up but i dont understand why on reboot it wont pick up this IOS and boot itself and why do i have to write boot command everytime on rommon.
I have also explicitly given the command "boot system bootdisk:IOSNAME.bin" in the startup config file but still no luck.
I have 6509 E. Actually what happen it last 3-4 times it reload its self and got stuck in rommon mode, i tried to boot it with boot by connecting a console cable on supervisor 720 2b. What and where is problem and why is stuck in rommon after reload.
I tired to upgrade the flash memory on my 871. I have tired to send single break and removing the flash card to drop the 871 to rommon. but no luck, all i get is the below error. I have try restart button on the back and get the same results. How to get the router into rommon mode so i can place the IOS on the flash ?
i have a Cisco 6513 it is used one, i have tryed to boot it but it did not work, it alwayes go to rommon mode and i am not able to know what is the issue,
when it boot i get the below outpot from the switch.

if it is possible to recover a Cat 6500 that has no code on bootflash from ROMMON, and is it mandatory to have a compact flash card to do the recovery ? or can one use xmodem or TFTP ?
I have ROM MON version 12.2(17r)S2 and I am trying to determine if I need to chnage this to 12.2(17r)SX7. It does not appear I need to with the upgrade to 12.2(33)SXI10. Is this correct?
I have a 7600 with ws-sup750 and when it boots it displays these errors:
Cisco IOS Software, s72033_sp Software (s72033_sp-ADVIPSERVICESK9_WAN-M), Version 12.2(33)SXH2a, RELEASE SOFTWARE (fc2)Technical Support: [URL] Firmware compiled 07-Apr-08 22:12 by integ Build [100] 00:00:05: %C6K_PLATFORM-0-UNKNOWN_CHASSIS: The chassis type is not known.(0x6003)
[Code]....
Then it got stuck in rommon, i tried using a 7200 pcmcia card (I downloaded the 7600 IOS there) but if i do from rommon boot disk0:
it complaints with :open: file "c7200-atafslib-m" not found so, it doesn't boot.
Anything I can do to be able to boot this device ?
Yesterday I tried to install c2960-lanbasek9.mz.12.55.SE4.bin onto my router. When I changed the boot commands, I did not leave the 2nd option in there and the old firmware has an .ex3 extension. After trying to boot to this new image, we receive a looping error message that continues to reboot and go through the same process.Basically the error is "ERROR: firmware not supported by hardware"I have power cycled it a few times but durning bootup, I never see the ################## which would allow me to BREAK sequence and get into rommon. The device simply waits about 30-40 seconds after boot and goes right back to the looping reboot sequence and the error message. Is there any hyper term or putty settings to change on this?
I have a Catalyst 4506e that works fine but if reload, it boots in rommon mode. I can start it with a boot command, but by default, i must type a command. My config-register is 0x2102.
So I thought I'd upgrade to IOS-XE 3.2.0SG to hopefully resolve the issue. I was reading the software release notes and it says:
If you are upgrading to 3.2.0SG, you must upgrade your ROMMON to 15.0(1r)SG2.If they have dual supervisors, first upgrade your software to 3.2.0SG, then upgrade your ROMMON to15.0(1r)SG2 to avoid the resets uplinks issue (CSCtj54375).
And from the ROMMON release notes it says:
Download the cat4500+e-promupgrade-150_1r_SG2 program from Cisco.com, and place it on a TFTPserver in a directory that is accessible from the switch that is upgraded.The cat4500+e-promupgrade-150_1r_SG2 program is available on Cisco.com at the same location from which Catalyst 4500 system images are downloaded.
So I have several questions:
The only promupgrade file I can find is cat4500-e-ios-promupgrade-150-1r-SG2 (which doesn't appear to be the same as cat4500+e-promupgrade-150_1r_SG2 ). Where the correct file is?Since I have dual supervisors, it says I should upgrade the software, then the ROMMON. If I can do that (run the new software with the old ROMMON) why am I bothering to upgrade the ROMMON in the first place? (update, ok, I see the new ROMMON gives me enhanced crash info and will allow future upgrades without bringing down both supervisors at the same time).When these were ordered/installed, the licenses were all mixed up (I wasn't involved with that ). So the MDFs have dual sup 7e with ipbase and the IDFs have single sup 7e with enterprise services. Obviously, we want the enterprise services in the MDF so we can run OSPF and the ipbase in the IDF. But, OSPF seems to be running just fine in the MDF on ipbase. Are the licenses not enforced on these platforms? The release notes for 3.2.0 say ipbase doesn't support OSPF. So if I upgrade the MDF switches, will OSPF suddenly stop working?
The IP Base image does not support enhanced routing features such as Nonstop Forwarding (NSF) , BGP, Enhanced Interior Gateway Routing Protocol (EIGRP), Open Shortest Path First (OSPF), Intermediate System-to-Intermediate System (IS-IS), Virtual Routing Forwarding (VRF-lite) and policy-based routing (PBR).
Got a long lingering, year long issue that has spanned about 8 supervisor cards and a complete chassis swap. The 6509 acts as a ITN in our facility. The active sup card at random points of pipe usage boots into rommon mode, seriously inhibiting our company. I'm able to swap the 2 fiber pairs that we had going into the active supervisor card into the secondary and usually this works for another random amount of time, however, today it occured within minutes of hooking up the fiber links. Sitting there for about 5 minutes it booted into ROMMON. When this happens, I'm able to boot the sup card back to good status. Previous remedial actions, other than replacing sup cards/chassis, was checking the config register and making sure it was x2102. Previously, it was not, and we corrected and reloaded and it took, we thought this would fix the problem, until today.
I have a 3550 switch that was replaced at a remote site with no IOS. This is a switch not a router so tftpdnld does not work.
[Code]...
The problem is the switches interface never comes up so try to connect to the tftp server. I read on google it can't be done on a switch to copy from tftp to flash in rommon mode on a switch and to use XMODEM. My problem is I do not have access to it, I ssh into a 3640 which is an access server for all devices and that is how I have console to it, how to use XMODEM over ssh.
But I'm fairly certain that there has to be a way to just copy it from tftp? I have a 3550 local and when I put it in rommon mode it stops the port check at port, port 1 goes from green when you plug it in to off then port 2 changes to amber and the rest green. So just by the look of this I would believe tftp would work; you just need to use port 1.
On my 6509-E, all the modules show this: Region F1: INVALID Region F2: INVALID Currently running ROMMON from S (Gold) region
Is this alright? Is the Gold region like a default region where ROMMON is always installed. And are F1 and F2 just storage partitions that are available to hold backup copies of the ROMMON? From what I read, it sounds like I can copy ROMMON images to F1 and F2, either the same version as the Gold region or different versions. Is that correct? Why would I want to copy different ROMMON versions to F1 and F2?
We have a cisco catalyst 6509 with Supervisor Engine . After power outage, the switch always start in Rommon mode. Configuration register is 0X2102, we want to it always start in normal mode. What should i do?
I'm fairly new to networking and need to migrate an old core to a new core. I have a 6509-e Switch that I had an RMA on one of my 720 sup cards. After receiving the sup card I swapped my slave out with the new one, expecting it to boot into ios. It booted into Roman. I tried to boot the image manually and it did the same thing. I also tried to boot from my flash and, again, booted into ROMmon.
Question: If i configure and change the boot to boot from image it tells me i need to reset or power cycle first. Will this reset the entire switch? As this is production I'd rather not.
I am at home now, but I can supply any logs/hardware model/configs tomorrow. I thought I would see if this is an easy fix.
I have a 512MB USB Flash device and was able to boot the IOS on the C2960 from it.After that i tried to Copy the IOS file from the USB to the system flash, but it could not find the USB Device.At plugging in the device the systems tells me: "Transfer type 2 not supported" I configured the USB device in NTFS and FAT both are able to boot with the ROMMON, but the normal system does not accept them and i know i can do the copy over a TFTP from my laptop, but it is strange that rommon accepts the usb device and the system does not?
i have recently tried to change the catos on a Catalyst 2948G-L3 and since then i have the following message in a loop :I know that the solution would be to download a new valid image from tftp via the rommon prompt but what i dont undertand is why i cant access the rommon prompt. It justs boots with the message above in a loop
I have one cisco 4507R+E.My question is if the IOS of the acive SUP crushed and the switch is running through it's second SUP then how to restore the IOS of the first SUP.Also how to access the ROMON mode of the crushed SUP when switch is running through second SUP.
I would like to upgrade rommon on my Cisco 2801 but this is what I get: [code]The router stops here and I am forced to power off and on again and the upgrade does not succeed.
I have blown the dust of my Cisco 1801 and looked the books out to put a decent router on my network now I am running my own server however I have hit a few bumps but totally stick now.
DHCP is disabled and I can't remember the sub net. Connected with the console cable but finding my admin password isn't accepted. Running the password recovery but unable to access ROMMON using special command > break. I should get this but the ATA monitor library just loads and I get stuck on the password screen.
*** System received an abort due to Break Key *** signal= 0x3, code= 0x500, context= 0x813ac158 PC = 0x802d0b60, Vector = 0x500, SP = 0x80006030 rommon 1 > #
From what I gather (still green behind the ears) the ROMMON command has been disabled. Any way to get into my Cisco or do I need to reload the IOS on the flash card?
We recently deployed a FWSM on our 6503-e boxes (w/ sup720). NAT is working (PAT) but the issue I am seeing is private traffic from remote sites is not being allowed through the FW. I was able to get the remote site to ping the FWSM itself (inside address), but no hosts behind it. Maybe an ACL issue? Also when I turn off NAT on the remote end, I can than access everything (We are NATng on both ends). Im a routing guy by nature so I will defer this to the security guys out there.
I've got a 6503, SupII/MSFC running Native code, so I'm pointing the boot variable to disk0: (bootflash is not large enough for the image file). In using the wr erase, the boot variable is getting wiped as the wr erase removes all nvram files, and apparently the boot variable is stored there. I also tried the erase start, which also hits everything in nvram.
So, any clean way to wipe a config without forcing the router into ROMMON to reset the boot variable, or do I need to just expect that is part of the standard approach?
