Password problem on Catalyst 3750

Hi all,
I am an Unix administrator and we lost all account and password informations to connect on a Catalyst 3750 switch.
Is there a way to connect to the switch (With a serial cable?) an to create a new account without losing the configuration ?
Thank's for your reply.
Regards.

This method won't reset the configuration.
During the boot process, you rename the current configuration so it doesn't get loaded.
rename flash:config.text flash:config.old
When the switch boots, it loads a blank image. Then you rename the config file and load it into the running config and you can change the logon credentials to something you know.
It's important that you follow the steps exactly so you don't lose the configuration. Password recovery is a pretty common procedure.
The only other method of recovery is if you have a copy of the current running configuration. Send me a private message if you have this config and we can discuss the possibility.

Catalyst (3750 24 10/100/1000T) and (3750 12 SFP) Stacking Problems

Dear all
I'm having a very strange situation here (at least for me)
we have 4 core switches
2 x   WS-C3750G-24T-S Catalyst 3750 24 10/100/1000T + IPB Image
and
2 x   WS-C3750G-12S-S Catalyst 3750 12 SFP + IPB Image
Stack configuration is done this way
when the switches are powered on, the first two SFP core switches are seen as a single stack with the stack master LED turned green on the first switch
the other two (24 10/100/1000T) switches have the RPS LEDs always green, mode cannot be changed, and cannot be accessed by Console connection
but when the (24 10/100/1000T) are powered off, the first (SFP) switch in the stack reports that " Switch 3 and 4 has been removed from Stack "
which means they are stacked but there's something wrong, because
only the SFP ports are shown in the " Show interfaces status " , the ethernet ports of the bottom switches are not present !!!
can you please tell me what's the poblem ?

Dear Daniel
Sorry for my delayed response but i was actually quite busy
but the problem was actually in another sense
the default profile for the Catalyst 3750 SFP is the Aggregate SDM Template
while the 3750 10/100/1000 ethernet Switch Default SDM profile was Desktop profile
so i had an SDM mismatch

Hi and Welcome to the Community!
If you have BES, then you need to talk to your BES admin for the proper method to activate your BB on BES.
If you do not have BES, then you should not even be going into anything related to Enterprise email...instead, you should see Internet or Personal email setup in addition to Enterprise. If you do not see Internet or Personal, then your device is not properly activated by your mobile service provider for BIS-level Internet/Personal email services...contact them for assistance.
Good luck and let us know!

Trunking Catalyst 2950 to Catalyst 3750 problem

I cannot seem to figure out how to trunk a catalyst 3750 to a Catalyst 2950.
I've set
3750(config)#interface fastethernet 1/0/2
switchport mode trunk
switchport trunk encapsulation dot1q
BUT my Catalyst 2950 does not offer the "switchport trunk encapsulation dot1q" command
My 2950 is running IOS version 12.1(20)EA1a
is there a work around for this situation. Our network still employs a bunch of these 2950's.

The Catalyst 2950 series can only do 802.1Q trunking. It's the default, and only, choice. So there's no need to specify it when trunking.
In fact, since you don't have a choice of which encapsulation to use, there's no need for a "switchport trunk encapsulation" command. Which is why it's missing from the Cat2950 switch IOS.
This took me by surprise too, when I first transitioned out of the 3500XL series into 2950 and 3550 switches.

System FCS error frames on Catalyst 3750

Please,
may someone explain what are the "System FCS error frames" I see with "show controllers ethernet-controller" on some ports of a Catalyst (on trunk and also on access ports) WS-C3750G-24TS-S (3 switches in stackwyse)?
Error counters advance slowly, but they do grow... and I am afraid this could be the reason for variable slow access time to a server application menu...
For example "8 System FCS error frames".
The ports are connected to a PIX-515E and I see the same error count on the firewall interfaces (PIX "show interface" command shows me "8 input errors, 8 CRC, 0 frame, 0 overrun, 8 ignored, 0 abort")
A few errors may be seen also on other ports, connected to other (C3550)switches.
I tried to upgrade the IOS version, so I loaded "ipbase 12.2(25)SEB4 " on the Catalyst 3750, but it did not solve the problem.
PIX firewalls are running software 6.3(4).
Why these errors are called "System FCS error frames" ? I could not find anything searching on Cisco CCO!
Thanks

I apologies for the delay answering, my notebook has been down for 5 days and also cco access password...
Thank you for the explanation and suggestion.
We have a second rack with another three switch 4750 in stackwyse, same models as the "faulty" ones, and the errors are not present on those switches, so it must be something hardware related on the first group of switches.
I cannot touch those devices at the moment, we captured traffic frames with 3 Notebook PCs running "Ethereral" lan sniffer, traffic to and from the server and two clients and we discovered that in different ports of those switches, some packets never reach the clients, causing many TCP retransmissions, especially witch continuous traffic (http get and ftp transfers). This problem is visible on some, but not all, of the catalsyt 3750 switches in stackwyse, but in every one of the three switches. We are planning to go on-site and replace the hopefully faulty one ( or reseat the cables as you suggested).
Is this a problem you have seen before?

Do Cisco router 2811 and Catalyst 3750 support SNMPv3?

Hi,
Do Cisco router 2811, IOS 12.4(20)Ti, and Catalyst 3750, IOS 12.2.(53)SE, support SNMPv3?
Attached file contains my SNMPv3 configurations and "show snmp" results. Would you please give me your advice? Thanks.
Hugh

Hugh
Certainly both the 2811 and the 3750 do support SNMPv3. So support for the feature is not an issue in your situation.
I have looked at the config that you attached and believe that it looks reasonable. You have not told us about the SNMP server that will communicate with these devices. So we have no way to know if the details of the configuration are correct.
Have you attempted to discover these devices with an SNMP server that is configured to use SNMPv3 and has this user and passwords configured? If it does not work my first suggestion would be to check to verify that the passwords configured are exactly the same on the clients and on the server (and perhaps re-configure the passwords just to be sure). If the passwords are not a problem my second suggestion would be to check and verify that the authentication and encryption parameters match between the server and the clients.

Policer with IPv6 class-map on Catalyst 3750

Hi,
I've the following problem.
It's my goal to ratelimit incoming IPv6 traffic dependent on the destination IP address range.
On a Catalyst 3750 (Image: c3750-ipservicesk9-mz.122-55.SE1.bin) I've set up the configuration as follows:
mls qos
ipv6 access-list DESTINATION-RANGE-A
permit ipv6 any 2007::/16
ipv6 access-list DESTINATION-RANGE-B
permit ipv6 any 2B03::/16
class-map match-all A
match access-group name DESTINATION-RANGE-A
class-map match-all B
match access-group name DESTINATION-RANGE-B
policy-map RL-POLICY
class A
police 2000000 8000 exceed-action drop
class B
police 6000000 8000 exceed-action drop
interface GigabitEthernet1/0/7
switchport access vlan 90
load-interval 30
service-policy input RL-POLICY
The last CLI command which should bind the policy to the specific interface, leads to the following error message
QoS: class(A) IPv6 class not supported on interface GigabitEthernet1/0/7
Are hardware/software limitations the reason for this behavior or is there any misconfiguration?
Thanks in advance for your help!

Jens

If you are thinking of IPv6 prefix I tried everything. From /128 for single host to /64, nothing works.

Interconnecting Catalyst 3750 and 2948G-L3

I am trying to interconnect a Catalyst 3750 and a 2948G-L3 using fiber GBIC. The interfaces where the GBIC and fiber are attached show up as physically down. I have tried different ports and also changed both switches. No Luck. If I connect a 3524 to the 3750 using the same connection it works.
Are 2948G-L3 switches compatible with the 3750?
Thanks,
VT

Should have no problem. Can you try the following on the 3750's gig interface:
speed nonegotiate
See of the link comes up.

Configuring dual-links on catalyst 3750

I've dual-links (laser and Fiber optic media) to connect my office and colocation. both of using catalyst 3750, there are also 4 VLAN. the problem are Fiber optic provider only allow 1 VLAN to connect my network to colocation, when the Laser drop, Fiber optic can't send traffic to colocation.
is there any clue for this problem...?
thanks,

Hey,
Please give the Show config output from both the switches. Would like to see the config on both the ends.

Trunking between Huawei S3900 and Cisco catalyst 3750

One of my edge Huawei S3700 switches is dead, I am going to replace it with a Cisco switch Catalyst 3750 series PoE-48 via a trunk link with GE fiber port on both ends, please see the diagram below.
trunk trunk
Core switchrouter<----------S3700<--------------->Cisco Catlyst 3750
I haven’t touch Cisco switch for many years, I would like to ask the following questions:
1.)      Do I need to take any precaution before connecting this Cisco switch into my Huawei network? Only one link between S3700 and C3750, so I don't need worry anout STP? Do I need to worry about Default vlan regarding trunking port?
2.)      I need to use different trucking protocol e.g. 802.1Q etc to interconnect these two switches (S3700-28TP-SI-AC and Catalyst 3750), please see the following configuration:
For C3750:
switchport trunk encapsulation dot1q
switchport trunk native vlan (What you want)
switchport trunk allowed vlan (VLANs required)
switchport mode trunk
spanning-tree portfast trunk
For S3700:
port link-type trunk
port trunk permit vlan all
Do you think the configurations above are right?
Do I need to manually enter Duplex and speed options ?
3.)If the configurations are not right, then what are the commands for trucking port/link should I use on the Cisco switch (it uses IOS software) and Huawei switch? Procedures of the commands would be really helpful !
Any information and help would be much appreciated.
Thanks
Regards

Hello
3750 - basic config
================
See as you are using this switch as an host switch you need to make sure ip routing isn't enabled ( it isn't by default)
Also it looks like the s3700 Huawei switch is permitting all vlans and I assuming the default native vlan is 1 ( as is cisco) so no need to specify the native either.
If you are requiring the access ports on this new cisco 3750 to be in multiple vlans then usually cisco to cisco interconnect would ultise VTP for vlan propagation however this wont occur between the Huawei switch, so you will need to manually add the vlans on the switch also.
so to summarize below is a basic host switch config for 3750.
conf t
no ip routing
hostname XXXXXX
username xxxx privilege 15 secret xxxxxxx
service password-encryption
enable secret xxxxx

no ip domain-lookup
spanning-tree mode rapid-pvst

int vlan x ( this may or not be vlan 1 - its whatever the L3 vlan interface is on the core switch for management connectivity)
ip address x.x.x.x y.y.y.y.
exit
ip default-gateway x.x.x.x ( ip address of CORE SVI management interface)
vlan x,x,x,x ( add the L2 vlans to the switch as vtp would not be used between the Huawei switch)
exit
int gigx/x

Mls qos on Catalyst 3750

I can't understand dropping algorithm used by WTD on Catalyst 3750.
Giving the following configuration:
Switch(config)# mls qos queue-set output 2 buffers 40 20 20 20
Switch(config)# mls qos queue-set output 2 threshold 2 40 60 100 200
1. What happens if buffer utilization for queue 2 is between drop-threshold1 and drop-threshold2? Are the packets dropped using a specific algorithm as in WRED?
2. What happens if buffer utilization for queue 2 is between drop-threshold2 and maximum threshold? Are the packets dropped using another algorithm?
3. Is it true that with buffer utilization above maximum threshold all packets are dropped?
Thanks
Stefano

Paresh,
thanks a lot for your suggestions!
Anyway I still have some doubt related to WTD thresholds. The sintax is the following:
mls qos queue-set output qset-id threshold queue-id drop-threshold1 drop-threshold2 reserved-threshold maximum-threshold
For drop-threshold1 and drop-threshold2 the range is 1 to 400 percent. For reserved-threshold the range is 1 to 100 percent.
By default, drop-threshold1 and drop-threshold2 for queues 1, 3, and 4 are set to 100
percent. Drop-threshold1 and drop-threshold2 for queue 2 are set to 50 percent. The reserved
thresholds for queues 1, 3, and 4 are set to 50 percent. The reserved
threshold for queue 2 is set to 100 percent. The maximum thresholds for
all queues are set to 400 percent.
With these default settings, queue 2 has drop-threshold1 and drop-threshold2 set to 50 percent and reserved threshold set to 100 percent.
The problem is that drop-thresolds are percentage values related to the ENTIRE buffer, reserved threshold is related to the specific queue's buffer.
So with default settings (1/4 of total buffer for each queue) reserved threshold seems to be HIGHER than drop-thresolds!!!
reserved threshold = 1/4 total buffer
drop thresholds = 50% over 400% total buffer = 1/8 total buffer
Maybe there's something missing...
Thanks
Stefano

VGA output problem and catalyst control start up link

I do not know whether the problems are linked or whether I have made things worse. It started with an error message on start uo saying that there was a problem with Catalyst Control failing to start. It still alowed me to run normally until, in front of an audience, the VGA o/p link to a projector did not work. I had a spare cable which did not remedy the situation so my class sat around the laptop.
Another symptom is that the HDMI output does not work. I do not ko wif this is a separate issue.
With the notion that this was linked I set about attemping to delete and reinstall AMD drivers and blindly assumed this was where I would get the Cat Control update.
I used AMD's compatability checker and installed for display adapter AMD M880G with ATI Mobility Radeon HD 4250. The driver version is 8.770.2.1000 dated 19/09/2010
I cannot duplicate the display or use projector only however when I attach an external monitor the laptop changes resolution as if to accommodate the additional display.
I either need help to verify the applicability of the changes that I have made or I need help to plan a way out of the mess that I have made.

Hello @g_david,
I have read your post on how the Catalyst Control Center program is not working very well on your computer, and that you are not able to view your display on your HDMI connected monitor. I would be happy to assist you in this matter!
To ensure that your graphics drivers are working correctly, I recommend installing the original software and hardware drivers that first came with your notebook. This can be done by following this document on Using Recovery Manager to Restore Software and Drivers (Windows 7). Once installed, please follow this resource on Using HP Support Assistant (Windows 7) to update the drivers on your system.
If you are able to successfully use the Catalyst Control Center again, the next step is to re-connect the monitor to your computer using an HDMI cable. To do this, please follow the steps in this document on Troubleshooting HDMI display and sound issues.
Please re-post with the results of your troubleshooting, and I look forward to your reply!

I have a password problem. After importing data and settings from one MacBook Pro to a new one, I have to put my iCloud password in when re-starting, but the password from the old computer in when waking the computer from sleep.

I have a password problem. After importing data and settings from one MacBook Pro to a new one, I have to put my iCloud password in when re-starting the new computer, but the password from the old computer in when waking the computer from sleep. I want to use my iCloud password on both computers consistently. How can I fix this?

The only other place to change a password for the computer login is in Users & Groups preferences. But I don't really know enough here to fix your problem. You can try fixing the keychain:
iCloud- Frequently asked questions about iCloud Keychain
Tutorial: Resolving Keychain Issues
If you can't access your keychain, or forget your password If you can't get into your keychain file because you've forgotten your password or the keychain file appears to be corrupt, there are a couple of options.
First, if you've forgotten your password, you can use the "Keychain First Aid" utility to make the keychain password the same as the login password. This can be accomplished via the following process:
1. Open Keychain Access (located in Applications/Utilities)
2. Go to the "Keychain Access" menu and select "Preferences"
3. Click the "First Aid" tab
4. Make sure the "Synchronize login keychain password" box is checked
5. Close the Preferences window
6. Go to the "Keychain Access" menu and select "Keychain First Aid"
7. Enter your username and password
8. Click the "Repair" button
The second option is to completely delete your keychain then recreate it. This routine is useful if your keychain appears to be corrupt or otherwise inaccessible. This can be accomplished as follows:
1. Launch Keychain Access (located in Applications/Utilities)
2. Click "Show Keychains" in the lower-left corner of the window.
3. Select the problematic keychain from the left-hand pane.
4. Navigate to the "File" menu and select "Delete Keychain '(name of keychain)'"
5. Check all options for deletion and press "OK"
6. Create a new keychain by going to the "File" menu, then "New" and selecting
"New Keychain"
7. You can now make this keychain your default if you desire by selecting it, then
going to the "File" menu and selecting "Make '(name of keychain)' Default"
Login as root and perform repair In some cases, problems with keychains can only be resolved when logged in as the root user.
First, you want to enable the root user:
1. OS X Mountain Lion: Enable and disable the root user
2. OS X Lion: Enable and disable the root user
3. Mac OS X 10.6: Enabling the root user
4. Enabling and using the "root" user in Mac OS X
After enabling the root user, and logging in under this account, again open Keychain Access. First attempt repairs using Keychain First Aid, and failing that, delete then recreate the keychain as described above while logged in as root.
Persistently asked for stored passwords If you are persistently asked for passwords in various applications that you have specified should be remembered in a keychain, your "login" keychain may not be active for one reason or another.
Navigate to ~/Library/Keychains/ (this is the Library folder inside your user's home folder). Find the file named "login.keychain" and double-click it.
Failing that, select the "login" keychain within the Keychain Access application and make sure it is the default keychain by going to the "File" menu and selecting "Make 'Login' Default"
Turn off Keychain synchronization in applications having problems If specific applications are experiencing issues when accessing password-protected material, the Keychain may be to blame.
The above comes from an article published on MacFixit.com.

WRT110 WIFI password problem

Hi Everyone,
I've got a very strange problem. First, I indicated WPA under Wireless Security section and typed in my passphrase. However when connecting to my wireless network name my passphrase never worked. Second, I completely disabled security and tried to simply connect without any passphrase, but I was still being asked for a passphrase nonetheless. I checked and double-checked and saved settings making sure security was disabled, but I was still being asked for a passphrase when choosing my wireless network!
I could probably restore my WRT110 to factory settings, however I don't want to loose other configurations like certain open ports and IP addresses I opened up for firewall.
Is there a way for me to resolve my WiFI password problem without restoring to factory default? I just need to figure out how to make the WiFi passpharse work. Here's what I have there:
Security Mode: WPA Personal
Encryption: TKIP
Passphrase: 0sunspot0
Key Renewal: 3600 seconds
However, when I pick my wireless network and try to connect to it by typing in 0sunspot0, I get authentication failure!
Am I doing something wrong?
Thanks,
Victor.
