Catalyst 2970 switch,Errot:Orange or Amber LED on fiber SFP interface

Hi every one..
I am facing an error as it seems in one of my customers 2970 switches. There is a single fiber interface configured and connected to the Catalyst 6513 backbone switch. The fiber LED blincking in Orange or Amber. What could be the reason?? Some one told me that There is a hight traffic through the interface. Can that be the right answer???
Thanks in Advance

It means Port is blocked by STP and is transmitting or receiving packets.

Catalyst Blade Switches 3020 For HP Blade Chassis

I was trying to access Catalyst Blade Switch 3020 through serial port to reset the lost password. This Switch is plug-in to HP c7000 Chassis. I followed the instruction from Cisco documentation for this password re-set process as follows.
{ Step 1 Connect a terminal or PC with terminal-emulation software to the switch console port.
Step 2 Set the line speed on the emulation software to 9600 baud.
Step 3 Push the release latch on the front of the switch to the open position.
Step 4 Pull the switch partially out of the module bay until the power disconnects, and then push it in again. The switch restarts when it reseats in the server chassis. The switch performs POST after power is applied.
Step 5 Push the release latch on the front of the switch to the closed position.
Step 6 Within 15 seconds, press the Mode button while the System LED is still flashing green. Continue pressing the Mode button until the System LED turns briefly amber and then solid green; then release the Mode button.
------- Step 6 did not work. System LED neither flashing nor in Solid state. I can not connect through Serial port any more! Any help.....

Here in the "blade switch for HP" a request processing application is running in a server. when we use the same type server stand alone with a separate switch it processes 80,000 requests per 4 hours. But when this blade server in the blade switch it only processes near 6,000 requests per 4 hours.
That what I mean like "Network delay"...
That is what I cannot understand.
I have attached the current configuration of the blade switch so you can go through it.
Is there any best practices specific to that type of blade switch that should enable?
Thanks for your help

Catalyst 2950 switch

Hello,
I am using a catalyst 2950 switch and connecting machines which have the operating system as TRU64 UNIX 5.1B (HP make DS25 servers) and WINDOWS XP Professional. The WINDOWS machines are getting connected on the network ( I am able to PING each other), but the UNIX machines are not getting connected on the network. The port LED on the switch is normal (GREEN). The netstat -r command on the UNIX machine shows default as defgw (/etc/routes) and the IP of defgw is defined in the /etc/hosts file. But there is actually no such gateway.
Please help me to get the UNIX machines connected on the network.
Thank You very Much
Best Regards
S R Vijayan

I wonder if the Windows machines are configured to use DHCP? If they are configured for DHCP and there is a DHCP server that is reachable, then it explains why the Windows machines have reachability to each other. If there is not a DHCP server available then the Windows machines are probably taking addresses in 169.254 (which is the default for Windows when it can not acquire from DHCP). This would also explain the ability of Windows machines to communicate with each other. Can the original poster clarify what IP addresses the Windows machines are using?
Then the question becomes how are the Unix machines configured? Are they supposed to use DHCP? Is so is the DHCP server reachable? If not how is the interface on the Unix box configured?
I also think that the suggestion about verifying whether the switch is configured with more than one VLAN is an excellent suggestion.

Etherchannel trunking between 2970 switch & 2851 router

Hi.
I'm planning to do router on a stick with my Catalyst 2970 and my Cisco 2851 router. I got it working to do router on a stick with one physical link to do interVLAN routing, but when I try to configure it using an etherchannel trunk between them, I can't get it working. Please help. Here's my running config for the switch and router:

Using Catalyst 3550 Switch with Linksys Home Router and Cable Internet

I've about pulled what little hair I have out of my head on this one, and need some configuration help.
I have a Cisco Catalyst 3550 switch with five Windows 7 desktops, an Avaya PBX and five Avaya IP phones attached. All of these devices are on a 192.168.0.0/24 subnet, and are communicating properly. I will refer to this as network # 1. I also have SEPARATE network, we'll call network # 2, using AT&T ADSL service and a Netgear 4-port/wireless router/ADSL modem combo device, which is functioning properly with a couple of other Windows 7 desktops over its own wired Ethernet network, using DHCP, and also on a 192.168.0.0/24 subnet. I thought it would be a simple integration, just plugging one of the 3550's ports to one of the DSL router's ports, in order to give the five Windows 7 desktop computers on network # 1 internet access via the DSL modem. Guess I was wrong. When I connect the two switches together, although I get a good connectivity (green lights on both ports) and am able to ping the DSL router's gateway address (192.168.0.252) from network # 1's computers, the computers on network # 1 cannot access the internet. Also, the working computers on network # 2 lose their internet access as long as the two switches are connected together. I am not a Cisco guru, but there's got to be a way to make this scenario work. Can someone provide me with a 3550 configuration that will allow me to extend my internet service from network # 2 on the DSL router to my 3550 switch and their computers? Here's what I am looking for:
INTERNET ---> ADSL MODEM ---> NETGEAR ROUTER ---> CISCO 3550 SWITCH ---> NETWORK DEVICES WITH INTERNET ACCESS

The Netgear router is probably what's doing the natting. Is the 3550 configured for routing or is it straight L2? If you have the 3550 configured as L3, then it's going to be easy to do what you want. Just add a static route on the Netgear to point the subnet that it doesn't know about to the 3550. For example, if the Netgear is addressed at 192.168.1.1 and the Cisco 3550 is addressed at 192.168.1.2, but it also knows about the 192.168.0.0/24 (separate vlan), then you would put a static route on your Netgear for 192.168.0.0/24 to go to 192.168.1.2.
The way that I would do it is to create a separate vlan on the 3550 and assign an address to it. Once you do that, make the port that the other switch connects to an access port of that vlan. (It would need to be on the same subnet as the existing equipment.) All of your devices would use it as a default gateway and then you would do the rest as above. You could also use RIP between the Netgear and Cisco if you can't do static routing.

Catalyst 6509 switch

I have a problem with one of our catalyst 6509 switches. We had power problem and when I tried to power the switch on after the power was restored it take me to the rommon.
rommon>
I urgently need answers to three questions and would therefore appreciate it if anyone can help me out.
1. What is the cause of the switch not booting from flash but going to rommon?
2.How do I get into the switch and
3.How do I reset the switch to boot from flash and not going to the rommon
Hope a savior comes to my aid

Probably went into rommon due to incorrect or missing boot statement . You must already be in the switch if you know it is in rommon . If this is a native IOS box then just issue the "boot bootflash: " command and this should boot the box . Once booted up make sure the boot statement is correct . "boot system flash sup-bootflash: .

Catalyst 1900 switch issue - internal speed

Hello,
I have a catalyst 1900 switch which has been working for years without any issues. It is connected to a single subnet on one side (10 machines all on same class C) and to a service provider switch on the other.
Recently the ftp speeds from machine to machine on the inside became very slow (20K) on a 10M port, slightly faster on the 100M port.
The external (internet side) to internal machines however has not changed and is still fast as ever.
Has anyone ever come across this sort of problem and if so where could I start to troubleshoot it ?
Thank You
Burt

Hi,
Thank you for your response.
The switch (LAN side) is connected directly to 10 machines (these are webservers with multiple IPs configured)
xx.xx.xx.6-250
Switch itself is xx.xx.xx.254
*** Uptime is 19days (after a reset to try to find this problem)
*** STP (port fast mode) is enabled on all ports
*** Monitoring the receive statstics for each port shows FCS errors and Alignment Errors about 2% (each) of the total good frames. I am not sure if this is normal however there were always some FCS and Alignment errors.
*** Monitoring transmit statistics shows no errors.
*** the switch reloads when reset
*** not sure how to get crashinfo on this switch.
You can contact me offlist at [email protected] if you need report info as this appears to be limited to 4000 chars.
THank You

Configuring the Catalyst 6500 Switch for IPS Inline Operation of the IDSM

I understand how to configure the Catalyst 6500 switch so that the monitoring ports are access ports in two separate VLAN's for inline operation.
However, I don't see any documentation that describes how the desired VLAN traffic gets forced through the IPS.
In promiscuous mode, you can use VACL's to copy/capture and forward the desired traffic to the IDSM for analysis. I'm not seeing how to get the desired traffic through the IPS.
Note that the host 6500 is running native IOS 12.2(18)SXE.
Thanks for any assistance.

A tranparent firewall is a fairly good comparison.
Let's say you have vlan 10 with 100 PCs and 1 Router for the network.
If you want to apply a transparent firewall on that vlan you can not simply put one interface of the firewall on vlan 10. Nothing would go through the firewall.
Instead you have to create a new vlan, let's say 1010. Now you place one interface of the firewall on vlan 10 and the other on vlan 1010. Still nothing is going through the firewall. So now you move that Router from vlan 10 to vlan 1010. All you do is change the vlan, the IP Address and netmask of the router stay the same.
The transparent firewall bridges vlan 10 and vlan 1010. The PCs on vlan 10 ae still able to communicate to and through the router, but must go through the transparent firewall to do so.
The firewall is transparent because it does not IP Route between 2 vlans, instead the same IP subnet exists on both vlans and the firewall transparently beidges traffic between the 2 vlans.
The transparent firewall can do firewalling between the PCs on vlan 10 and the Router on vlan 1010. But is PC A on vlan 10 talks to PC B on vlan 10, then the transparent firewall does not see and can not block that traffic.
An InLine sensor is very similar to the transparent firewall and will bridge between the 2 vlans. And similarly an InLine sensor is able to InLine monitor traffic between PCs on vlan 10 and the Router on vlan 1010, but will not be able to monitor traffic between 2 PCs on vlan 10.
Now the router on one vlan and the PCs on the other vlan is a typical deployment for inline sensors, but your vlans do not Have to be divided that way. You could choose to place some servers in one vlan, and desktop PCs in the other vlan. You subdivide the vlans in what ever method makes sense for your deployment.
Now for monitoring multiple vlans the same principle still applies. You can't monitor traffic between machines on the same vlan. So for each of the vlans you want to monitor you will need to create a new vlan and split the machines between the 2 vlans.
In your case with Native IOS you are limited to only 1 pair of vlans for InLine monitoring, but your desired deployment would require 20 vlan pairs.
The 5.1 IPS software has now the capability to handle the 20 pairs, but the Native IOS software does not have the capability to send the 40 vlans (20 pairs) to the IDSM-2.
The Native IOS changes are in testing right now, but I have not heard a release date for those changes.
Now Cat OS has already made these changes. So here is a basic breakdown of what you could do in Cat OS and you can use in preparation for a Native IOS deployment when it gets released.
For vlans 10-20, and 300-310 that you want monitored you will need to break each of those vlans in to 2 vlans.
Let's say we make it simple and add 500 to each vlan in order to create the new vlan for each pair.
So you have the following pairs:
10/510, 11/511, 12/512, etc...
300/800, 301/801, 302/802, etc....
You set up the sensor port to trunk all 40 vlans:
set trunk 5/7 10-20,300-310,510-520,800-810
(Then clear all other vlans off that trunk to keep things clean)
In the IDSM-2 configuration create the 20 inline vlan pairs on interface GigabitEthernet0/7
Nw on each of the 20 original vlans move the default router for each vlan from the original vlan to the 500+ vlan.
At this point you should ordinarily be good to go. The IDSM-2 won't be monitoring traffic that stays within each of the original 20 vlans, but Would monitor traffic getting routed in and out of each of the 20 vlans.
Because of a switch bug you may have to have an additional PC moved to the same vlan as the router if the switch/MSFC is being used as the router and you are deploying with an IDSM-2.

Erasing a config and vlan.dat file in Catalyst 4507R Switch

Hi,
I am unable to erase the configuration from Catalyst 4507R Switch.When i do "write erase" and reload the switch,the configuration still remains on the switch.
Switch1#write erase
Erasing the nvram filesystem will remove all configuration files! Continue? [confirm]
[OK]
Erase of nvram: complete
mp024-dc-nr00#sh start
startup-config is not present
After this i did reload and configuration still didn't get removed.
I tried
erase /all nvram:
reload
This also didn't help.
I also tried:
erase /all non-default
reload
This also didn't help.
Can anyone suggest how to erase the config on Catalyst 4507R Switch.
Thanks,

Hi Saroj,
do you see the below symtoms:
Cat4500# write erase
Erasing the nvram filesystem will remove all files! Continue? [confirm]y[OK]

To erase the vlan.dat file on the 6500/6000 switches, issue the erase const_nvram: command. On the 4500/4000 switches, issue the erase cat4000_flash: command. On the fixed configuration switches, issue the delete flash:vlan.dat command.

Catalyst 2950 Switch flash_init error

Hi Everyone,
I'm new to Cisco products and have a small home lab set up. I have a Catalyst 2950 switch that I would like to restore to factory defaults. Here is the issue I'm having and can't figure out.
I pull the power, telnet into the console port, hold the mode button and restore power. The boot loader (Version 12.1(11r) starts and says the usual message the system was interrupted prior to flash initialization (Paraphrasing here)
I get to the switch: command line, enter flash_init. Flash states it initialized and then all I get is a < with an underscore under it prompt. Anything I try to type comes up as bizarre characters and I can not get back to a switch: prompt unless I reboot the switch manually. Unsure of what to do here.
Thanks in advance!

Hi mattymattlynch
Check the workaround on the following documents:
http://www.cisco.com/c/en/us/support/docs/switches/catalyst-2950-series-switches/41845-192.html
http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst2950/software/release/12-1_22_ea11x/configuration/guide/scg/swtrbl.html
If no luck , the flash might be corrupted and requires a replacement.
Hope this helps

Hi Reza,
Thank you for your quick reply, and for putting the record staright. As such, a helpful rating was provided
PS: Feel free to help me one more time if you happend to know folllow on this query :)>
I guess that the disributed function has been included in the standard mulitcast routing command because the key word is no longer needed. Or perhaps this platform does not support this at all.#
Once again , thank you for your help above.

Catalyst 3750 Switch

How many total Vlans can you create in Catalyst 3750 Switch ? I read a document about Catalyst 3750 Switch. This document is said that "Although the switch stack supports a total of 1005 (normal-range and extended-range) VLANs, the
number of routed ports". However, I am not sure. Can you confirm for me ? Thanks

this link should be of some help to answer your question.

Catalyst 4500 switch loses startup-config

I have a Catalyst 4503 switch. When I reset the switch it boots to new configuartion wizard.
I am writing the configuration to NVRAM using the wr mem command. I believe it may be to do with the config register:
Cat4503#sh bootvar
BOOT variable does not exist
CONFIG_FILE variable does not exist
BOOTLDR variable does not exist
Configuration register is 0x8101

You are right change it to 0x2101 or 0x2102 and you should be fine . 0x2102 will require a boot statement to boot correctly where 0x2101 will just find the first image in bootflash and load that .
