Catalyst 6506E not booting

Hi all,

We have purchased 2 6506E switches for our new branch. The problem is that one of them does not boot and it enters rommon instead. You have to force it to boot using the boot command in rommon every time it needs reboot. Below are boot configs from the switch.

6506-01#sh run | i boot

boot-start-marker

boot system flash sup-bootdisk:s72033-ipservicesk9_wan-mz.122-33.SXI.bin

boot-end-marker

6506-01#sh boot

BOOT variable = sup-bootdisk:,1;

CONFIG_FILE variable =

BOOTLDR variable =

Configuration register is 0x2102

Standby is not up.

6506-01#dir sup-bootdisk:

Directory of sup-bootdisk:/

1 -rw- 33554432 Dec 15 2008 08:19:58 +00:00 sea_console.dat

2 -rw- 33554432 Oct 7 2008 17:08:20 +00:00 sea_log.dat

3 -rw- 97119716 Dec 15 2008 08:00:56 +00:00 s72033-ipservicesk9_wan-mz.122-33.SXI.bin

I have tried to upgrade the IOS on both switches but the problem did not clear on the switch.

Any idea please.

Best regards,

Stanslaus.

Your current boot variable is set to sup-bootdisk:

no boot system flash bootdisk:

boot system flash bootdisk:s72033-ipservicesk9_wan-mz.122-33.SXI.bin

save the config, reboot... If this doesn't work please post the output of "show version" and "show boot" commands.

I am still unsure why the boot variable is not changing. Try rebooting the switch and change the config register in rommon and see if that helps. When you are in rommon type "confreg 0x2102" and hit enter and then type "reset" That will reboot the supervisor. Are you just typing "boot" in rommon or are you specifying the full directory and filename?

HTH,

Stanslaus,

Based on the output of the show boot command it does not indicate that you have specified an IOS to boot. Add this to your config and save then reboot.

boot system flash bootdisk:s72033-ipservicesk9_wan-mz.122-33.SXI.bin

HTH,

Mark

Thanks Mark,

The command is there already. See on my show run | i boot command. It is strange to me that the IOS does not appear on the show boot command. The IOS is installed on sup-bootdisk: of the supervisor engine.

Great!!!!

It resolves the problem. It is now booting without entering rommon after reset. The sh boot output still doesn't show the IOS but this is not a problem as the other switch was giving the same output. Thanks very much Mark!

I also have another scenario on another site which has also being a big problem to me for a long time.

I have this situation.

Three server farm, each with two real server, which should be accessed by their Virtual IP addresses in their respective ports, i.e. client request should be natted by the SLB to correspond to the real servers. This means that, clients are in different VLANs from the one with real servers. So clients connects by using Virtual IP addresses, and expected to be natted to the real one. Below is the sample of my configurations;

Server Farm Configurations

==========================

ip slb serverfarm SF_1

nat server

access Vlan21

!

real 10.152.1.69

weight 1

faildetect numconns 1 numclients 1

inservice

!

real 10.152.1.70

weight 1

faildetect numconns 1 numclients 1

inservice

!

Virtual Server Configurations

==============================

ip slb vserver VS_TCP1

virtual 10.154.0.47 udp 69

serverfarm SF_1

access Vlan1

replicate casa 10.200.0.13 10.200.0.14 1026 password xxx

inservice standby FW_Side

!

Now with this configuration, i need to achieve two things;

1. The virtual server needs to be configured to connect to the couple of ports with only one Virtual IP address.

2.The clients, who are in VLAN one, should use the virtual IP address, i.e. 10.154.0.47, to connect to the real servers in ports 20/21, 25 and 69 and any other specified after step one is configured for the couple of ports.

If you have any Idea please.

Again thanks very much for your support.

Best regards,

Stanslaus.

I am glad I was able to help you with this. I would start a new thread on this issue as I am not too knowledgeable on that particular subject. The server networking forum would be the best place to post this question.

More than likely the config register is wrong on either the layer 2 supervisor or the layer 3 msf . Verify once its booted up that both the l2 supervisor config register is 0x2102 and the msf is also 0x2102 , my guess is that one is incorrect , we have seen this right from the factory . From the msf try "remote command switch show bootvar " and check the register.
