Cisco Switching/Routing :: 3550 - Copy IOS To Switch In ROMmon Mode?

Jan 24, 2012

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.

Cisco Switching/Routing :: Cannot Get Out Of Rommon Mode 1760

Dec 10, 2011

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.

Cisco Switching/Routing :: C2960 USB Flash Device Works In ROMmon But Not In Normal Mode?

Aug 7, 2012

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?

Cisco Switching/Routing :: 3750X / Copy IOS From One Switch To Another?

Feb 27, 2013

It seems I have seen this before (and even done it once a few years ago).. but it has been a while. I have a stack with a Cisco 3750 stack that I have to replace a member.The replacement switch is a 3750X.
 
I think I have to upgrade the IOS of the older switch to be the same as the 3750X.
 
Current switch:      WS-C3750G-48TS     12.2(46)SE           
TO BE ADDED      WS-c3570X-48          15.0 (1)SE2
 
It seems to me there was a way to upgrade the older switch IOS from the newer switch or downgrade the newer switch with the older IOS.I dont have the Cisco account to download updated IOSs.

Cisco Switching/Routing :: 3500xl Switch Will Not Load Flash Or Copy From Xmodem?

Dec 7, 2011

I am trying to configure a switch that was given to me. They don't know the password to anything. I have already tried to recover it. The problem is, the switch doesn't load flash, or will copy flash from xmodem either. It also doesnt load the helper or boot. It is user mode and lets me do nothing. It doesnt let me use the enable command to get into it. I would like to start the config from scratch. Its a 3500xl switch, 24 ports. I dont know what to do with it. I am trying to study for my CCENT Exam and would like a switch that worked.

Cisco Switching/Routing :: VLan Routing Same Switch 3550-12T?

Mar 10, 2013

I'm having some problems setting up vlans to talk to each other on a 3550-12T switch. Its quite a simple setup I have, but I need to split my network up.
 
Currently I have a network of 192.168.25.0 255.255.255.0 I want to create a new vlan network of 192.168.30.0 255.255.255.0 So I have configured my vlan1 (default vlan) to have an ip of 192.168.25.250 for getting to the management page
 
I have created a vlan2 of 192.168.30.1 255.255.255.0 ?I have a port 10 linked to one of my 3560G's?In port 9 which is on vlan2 I have my pc plugged in with a static ip of 192.168.30.50 from the router I can ping any device on 192.168.25.x.
 
I can not ping 192.168.30.1 (which is my vlan2) nor can i ping the PC.
 
I have enabled ip routing  But I dont have a default route, this is becase we don't have a router on the network.

Cisco Switching/Routing :: GLC-GE-100FX - Connection To 3550 Switch Over MMF

May 21, 2012

i have an OM1 MMF fiber run between two switches, the first being a 3750 and the second being a 3550.
 
The link currently exceeds the maximum distance for OM1 @ 1000Mb/s (220m) so i would like to downgrade the link to 100FX using the necessary SFP's/GBIC's to extend the maximum distance to 550m and run the link @ 100Mb/s.
 
I have the part code for the 100FX SFP to install in the 3750 (GLC-GE-100FX) but cant find a 100FX GBIC for the 3550, can I use a 1000SX GBIC (WS-G5484) for the 3550 at one end and the 100FX SFP at the other? Any success with this configuration over MMF?

Cisco Switching/Routing :: Port Unreachable Messages On 3550 Switch?

Jan 24, 2012

While working at a client site today, I was troubleshooting some ICMP connectivity for a network we have created.I turned on 'debug ip icmp" on the 3550 switch int he middle, and was inundated with the following debug output:
 
Jan 25 11:01:14.641: ICMP: dst (172.16.1.7) port unreachable rcv from 172.16.1.5
Jan 25 11:01:14.641: ICMP: dst (172.16.1.7) port unreachable rcv from 172.16.1.5
Jan 25 11:01:14.641: ICMP: dst (172.16.1.7) port unreachable rcv from 172.16.1.5
Jan 25 11:01:14.641: ICMP: dst (172.16.1.7) port unreachable rcv from 172.16.1.5

[code]....
 
This output fires several times a second, and based on how often it is firing, I am curious if it may be a culprit with respect to the fact that the client has indicated that they have some slow internet.Should the next step be to look at the workstation at 172.16.1.5?

Cisco Switching/Routing :: Catalyst 3550 Switch - Dynamic QoS Setup

Mar 28, 2012

I live in a condo building that uses 3 Cisco Catalyst 3550 switches connected to a Comcast router with 100 Mbps download. Currently we regulate bandwidth by providing each user with 3 Mbps download. Even if only two people are active they still only get 3 Mbps download. I would like to set it up so if two people are using they each get 50 Mbps; a sort of 'dynamic qos. Is this possible with these switches? Would we have to purchase a Cisco router in order to provide this feature?

Cisco Switching/Routing :: Changing Native Vlan On 3550 Switch

Dec 22, 2012

I am having trouble after creating a management vlan (99) on a 3550 switch.I have configured the vlan (99) and given it an IP (192.168.1.100) and a default gateway (my router address - 192.168.1.99).I can ping to the switch from a PC and vice versa. The management VLAN IP is fine but now I cannot ping to the router from either the PC or the switch.It seems that just by adding VLAN 99 with it's own IP address has now prevented pings from the switch/ PC to the router ?Due to the fact that I have created a new switch management VLAN with an IP, does this mean I have set up the router as a 'router on a stick' scenario ?

Cisco Switching/Routing :: Internet Access For 3550 Switch VLANs?

Feb 22, 2012

I have a small cisco switch cluster (seven different 2924, 3524cisco switches) with 3550 as a cluster control which does all the inter vlan routing that works fine.
 
This cluster is in semi production PBX interop testing lab. This is a closed network without internet access and not connected to our corporate network.However now I have to add this capability so some equipment in the lab can get Microsoft updates over the internet.
 
I've created a port on a 3550 (fa0/19) and connected it to another network that has internet access. It picked an ip address and when I'm logged in to the 3550 I can ping hosts on the outside network. However I can't ping any hosts on that network from any hosts that are connected to my vlans.I've tried a few different things, but still can't make it to work.
 
Here is a short version of my 3550 configuration:

!
version 12.2
no service pad
service timestamps debug uptime
service timestamps log datetime
no service password-encryption

Cisco Switching/Routing :: 3550 Switch - Software Forced Crash Exception

Feb 7, 2013

Our switch had a little crash-fest this morning at 2:30 AM. I did find a web page about diagnosing Software Forced Crash Exceptions, but it did not look like ours was one of the more easily-identifiable ones.
 
It may be worth noting that we've only used this switch for about a month, everything seemed fine until now. When we got the switch it did not have any GigE modules, and this week we put 2 into it and have been using them for 2 servers.
 
It looks like the switch was crashing repeatedly over a period of 20 minutes, and then it stopped and normalized. In the logs of the router that this switch uplinks into, we could see the ethernet port flapping during the time that the switch wasn't reachable.
 
Here's the Show Stack on the switch:
