Cisco Switching/Routing :: Hang During Boot Of WS-C4948-S Switch
Apr 3, 2013
I encountered an issue while trying to boot Catalys WS-C4948-S switch. I power on the switch and I'm able to see the boot messages thourgh serial console cable. But it gets stuck at line "Image text-base: 0x1000000, data-base: ..... ". Also I can enter into rommon mode. I tried to use different kinds of IOS images, tried to boot from tftp but with no luck, the issue is the same.
There are no erros on the screen, it just gets stuck when it enters into IOS, so I don't see the IOS prompt.

We having a VSS switch (9 slot chasis) with ios "s72033_rp-ADVENTERPRISEK9_WAN-M), Version 12.2(33)SXI4", slot 7-9 are currently free. We wanted to install WS-X6708-10G-3C module on slot 7. Once we installed the module it didnt come, after waiting for 15-20min again we removed and inserted, but module didnt come up and we could see following logs on the console:
Jan 12 08:57:40.146: %ISSU-SW2_CFC2-3-ERP_AGENT_SEND_MSG: client/entity send failed; error code is timeout
*Jan 12 08:57:40.330: %ISSU-SW2_SPSTBY-3-ERP_AGENT_SEND_MSG: client/entity send failed; error code is timeout
Jan 12 08:57:40.146: %ISSU_ERROR-SW2_CFC2-3-START_NEGO_FAILED: ISSU NTI Client(2040): failed to start negotiation (ISSU_RC_CLIENT_ENTITY_DOES_NOT_EXIST_IN_PEER)
[code]....
Afer some time VSS switch didnt response to console commands and all the users in access switches were not able to reach the gateway (VSS). Then the problem disappeared once we rebooted both the switches in VSS.why the VSS switch become non-responsive?

I was trying to configure an SF 300-24 for use in my home and obviously did something dumb. It was working fine. The f/w was updated and I had configured 2 VLANs. VLAN2 was ports 1-6+GE1 for IPTV streaming and VLAN3 was ports 7-24+GE2 and GE3 for the rest of my LAN. I was plugged into GE4 and was configuring the switch with a laptop. GE4 was the only port still on the default VLAN1. I chaged the default VLAN to VLAN3, which forced a reboot and the switch never came back up. Attached is what I see when I connect to the console port: [code]
I can't access to GUI using it's static IP or it's default IP on any port and the console never reaches the point where I can log in. The System light is flashing green but the boot sequence never progresses past what's in the screen shot. I tried to do a hard reset using the recessed button on the front panel but it does not seem to have any effect, no matter how long I hold it down.

Working on a C4948-10g switch. Trying to reset switch to factory settings. I have ran the Switch#>wr erase, command but the vlan's are still in the config. If you do a show vlan it still shows all the vlan text. I have tried the Switch#>delete vlan.dat, doesn't work. Tried Switch#>delete nvram:vlan.dat, doesn't work. Tried Switch#>erase startup-config, doesn't work. How can I get rid of the vlan's?

I am running (cat4500-ENTSERVICES-M), Version 12.2(53)SG2 on the switch. I have a scenario where I have 3 end user equipments connected to a Cisco 4948 L3 switch. At the switch end port 1/46, 1/47, 1/48 are the terminating points for these 3 devices . I have added these three ports to VLAN140 (switch port access vlan140 on the gig interfaces).
The device connected to 1/46 is the one I'm testing some signalling features on. My requirement is to have intermittent packet drop on this interface so that my signalling associations would go down now and then. I'm trying to simulate a real-time network congestion/latency/packet drop in a simple manner.
I do not want to shut/no shut the 1/46 intf to cause this. Some way to achieve intermittent packet drop on this gig1/46 intf ?

Was building a small network in Cisco Packet Tracer and ran in to an issue. I have 4 routers running OSPF, and off one of the routers I have 5 3560 Multilayer switches. The router that the switches hang off of, I have a sub-interface with dot1q encapsulation, set for vlan 10 and an IP Address. 10.14.16.1/24. The switches have interface vlan 10 configures, and have IPs in the same subnet. From that router, I can ping/telnet to all the switches without issue. My problem arises when I try and reach those switches from any other router. OSPF is set to redistribute static and connected subnets.The routing table is populated correctly on all the routers. When I ping and trace the packet, it looks like it makes it all the way to the respective switch, but the packet never makes it back. I've played with the default route on the switches to no avail. Am I trying to implement this incorrectly, or am I just missing something?

I unpacked a new 3560x and went to put our standard code version on it c3560e-ipbasek9-mz.122-53.SE2. Everything seemed to upgraded fine but it won't boot to a console prompt. It seems like it loads the IOS image fine but can't get passed the Front-end Microcode IMG MGR: Programming device 0. [code]

my Catalyst 3750 switch. Following a power cut the switch no longer boots up. The SYST light flashed green but no POST checks are made. I cannot see any boot messages from the console port either. The switch was on a UPS but some thing may have damaged the switch.

What would happen if I installed a 32MB (MEM870-32F=) flash upgrade card in to a Cisco 871 router that already had 28MB flash on-board already? Would the router boot seeing 52MB (the max this router can have) or would it fail completely since the combined total would be over 52MB?
I know you can get a 24MB upgrade card but they are quite expensive.

i want to boot my Router's IOS from TFTP server but when I use the command: boot system tftp c2801-adventerprisek9_ivs-mz.124-24.T7.bin 172.16.10. 200; after that I write-mem, it shows the log:
-Router#wr

-ROMMON: out of room in table, cannot set "BOOT"
And when I reload the router, it cannot boot IOS from TFTP Server, sure my TFTP work well and 2801 can ping to TFTP.

I can see the boot file at 192.168.100.1 but I can never get into the GUI. The unit boots up, fans running. Eventually the power light flashes red. I don't have the unit hooked up to anything else except a laptop to try and configure it.

I have a 4503-E on my work bench. It's been out of production for a year or so. I started working on it last week. I think I may have cause a boot up problem. It comes up to ROMMON, but then I need to type "boot" to get it to come up all the way.
config-register = 0x2102Autobooting using BOOT variable specified file.....
Could not find a valid file in BOOT environment variable.BOOT variable can be set from IOS. To find currently setRom Monitor variables, please type 'set' command.
For choosing a boot method, type 'confreg' command. rommon 1 >
For choosing a boot method, type 'confreg' command.rommon 1 >
At this point I type "boot" and it proceeds to the normal bootup. (Below are a couple more print outs)

One of the 6500 was going in bootrom mode, so I have formated the flash disk using the other Cisco 6500 switch and copied IOS file to the boot disk. But the 6500 booting failed.

Customer is using SUP720 with SP rommon image version 8.1(3), he is trying to boot the new ios image from disk0, but he gets invalid magic error. he fomat the disk0 but still he gets error when he boots from disk0. He suspect that it can't be flash problem but can be software of hardware as he has two flash with same issue on 2 switches.
Customer wanted to recreate, I tried in the lab, i was able to load from disk0, but sup in lab had 8.5(4).
Customer wanted me try with 8.1(3) version. But i was unable to downgrade the SP Rommon image. SP rommon is running in Gold region and I loaded the 8.1(3) from both disk0 and sup-bootdisk, even preferrence was given to region1 but still sup came up with gold region itself.
* Will i be able to downgrade from 8.5(4) to 8.1(3), if so, what are the steps.
* is there any limitation or bug where 8.1(3) will be unable to read disk0.

I have been looking at grading the IOS version on our 6509-E however there is not enough space on disk:0 to upgrade to the version I need to install. The question I would like to ask is - is it possible to boot the IOS from a TFTP server? If this is possible what configuration do I need on the 6509 to enable this. How does the 6509 know about the TFTP server as an IOS is not installed and therefore it will not have a network configuration

after upgrading IOS image to V15 on four 2960S switches: Should I make the boot loader image to match the IOS version?I never thought about this while upgrading IOS image unless there is boot issue. I googled for answer but no luck there...
I checked download section on Cisco.com for C2960S-48FPS-L switch and there is simply no boot loader image..The running boot loader is C2960S-HBOOT-M Version 12.2(55r)SEThe running IOS is: 15.0 (2) SE2.

Once the xmodem copy is complete I performed the following sequence of steps:

Every time I delete the directory flash and reinstall it, I get an error:
Error loading "flash:c2950-i6q4l2-mz.121-12c.EA1.bin"
Error loading "flash:c2950-i6q4l2-mz.121-12c.EA1.bin" Interrupt within 5 seconds to abort boot process.
That is the message I get. It's set to NO manual boot, but it keeps making me manually boot it. I am at a loss, I've done 3 switches and they all keep doing the same thing.
