I cannot connect by console port to Cisco Catalyst 3750 using ethernet to USB.
Hello. I have one Cisco Catalyst 3750 switch, and two 2950 switches. I am trying to reset their settings using a console cable with a trendnet Ethernet to USB adapter. When I try loading hyperterm or putty on com3 there is no signal. I have the communication port setting on com3. I don't know what the old settings are, and they can be reset. I get connectivity lights when plugging the cable into the switch ports. What am I missing?
Are you definitely using the correct COM Port number? On Windows7 Right Click My Computer > Manage Then select Device Manager and expanPorts (COM & LPT)d in my case is shows Prolific USB-to-Serial Comm Port (COM5).
Once you have the right COM Port number just use the default settings in Putty. You may find the COM Port is locked up which will require a reboot.

Hi,
Can anybody help me to try and execute any program with the J2ME Toolkit. After loading the jad file from the samples I get the following error. This happens irrespective of the application I try and the applications do run on the Nokia toolkit I have installed. The error is as follows:
Running with storage root DefaultColorPhone
Cannot connect socket to port 3279
Windows error code 10061
Cannot open socket for LIME events on port 3279
I am running Windows XP Pro, JSDK1.4.2.
Thanks for your help.

plzzz reply -
ok here is deal.
the WTK was working fine for the existing demos.
then i tried to write code of my own, since the code couldnt compile (javax.microediton.* wasnt found) i overwrite the existing installation with a new, and the compile was fine......
But now i cant "Run" any project/class i get this ERROR msg:
Project "Games" loaded
Project settings saved

------>
Running with storage root DefaultColorPhone
Cannot connect socket to port 1179
Windows error code 10050
Cannot open socket for LIME events on port 1179
what have i donw wrong, how can i fix this? Already tried to re-install but nothing .
Ty for any help.ok in the J2ME WTK 2.2 Beta 2 i get the problem i mention before ,error while running,(BUILD IS FINE) but now on any port and i mean ANY
in the J2ME WTK 2.1_02 version,on the other hand, I Cannot Build (even the presaved sun classes) but i can RUN......
should i build in the 2.2 and then copy/paste the class files in the 2.1 directory and run from there? i imagine that could be a solution but not an error solving one.
This is WEIRD???????? :confused:
Can some one give me a FULL istraction what to do?
I am using the 1.5 SDK (java 5.0) but this should be irrelevant since both the runing and the building are "partially" done..... im not joking i cant image what is wrong........ btw did i mention that my computer has its own will? -
Dear All,
I cannot connect to my Exchange account in Outlook 2013 using "Microsoft Exchange Server or Compatible Service".
First I would like to present my network environment, I have 4 physical servers;
The first one is holding the Domain Controller 1, IP@: 192.168.1.10
The second server is holding the additional Domain Controller which it is DC2, IP@: 192.168.1.11
The third server is holding the Exchange 2013 Mailbox, IP@: 192.168.1.15
And the last server is holding the Exchange 2013 CAS-HT, IP@: 192.168.1.16
I am doing the steps below:
1-Creating a new profile in outlook and start configuring the exchange account by entering the IP address of the Exchange-CAS Server, 192.168.1.16
2-entering the account name: [email protected]
3-Go to "More Settings" > "Connection" > "Connect to Microsoft Exchange using HTTP" > and entering the "Exchange Proxy Settings"
4-type the exchange CAS Server URL, https://192.168.1.16
5-Check the "Connect using SSL Only"
6-Authentication Settings: "NTLM Authentication", and pressing Apply
7-When I press the "Check Name" button, a message occurred> "The action cannot be completed. The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action".
8-I go back to the "Exchange Proxy Settings" and I Uncheck the "Connect using SSL Only" and pressing Apply
9-i press the "Check Name" Button, a small window occurred to enter a Username and Password, so I enter the Administrator username and the administrator password and pressing "OK", but nothing is changed, I tried to enter my
username and password in the small window and I still got the same result.
I cannot verify the account name and I cannot complete the process.
I appreciate you kind assistance.Hi,
To narrow down the cause, I’d like to recommend the following troubleshooting:
1. Try to login the test account through OWA.
2. Check the Autodiscover settings: get-clientaccessserver |fl autodiscoverserviceinternaluri
3. Check the result of directly accessing the following URL:
https://autodiscover.domain.com/autodiscover/autodiscover.xml
Thanks,

Debian Linux Bonding and Cisco Catalyst 3750 - best practise?
Hello everybody,
I would like to know what's best practice to do this:
The two NICs of a Debian Linux server wants to be connected with two Switchports of a Cisco Catalyst 3750 switch(stack). My goal is to have load-balancing and failover.
My /etc/network/interfaces looks like this:
iface bond0 inet static
address 192.168.0.30
netmask 255.255.255.0
network 192.168.0.0
broadcast 192.168.0.255
gateway 192.168.0.1
dns-nameservers 192.168.0.10 192.168.0.20
dns-search xyz.mycompany.com
slaves eth0 eth1
bond_mode ???
bond_miimon 100
bond_downdelay 200
bond-updelay 200
First question: What bond mode should I use?
The switchports looks like this:
interface GigabitEthernet3/0/4
switchport access vlan 20
switchport mode access
spanning-tree portfast
What changes are necessery here? Something like this?
interface GigabitEthernet3/0/4
switchport trunk encapsulation dot1q
switchport mode trunk
spanning-tree portfast
Thanks a lot for suggestions, hints, etc.! :-)

StephanHi Michael,
thanks a lot for your answer - and sorry for my late reply!
I like to show you my solution - I hope that it is a solution. ;-)
My config on the switch(stack):
switch#show etherchannel summary
Group Port-channel Protocol Ports
------+-------------+-----------+-----------------------------------------------
2 Po2(SU) LACP Gi3/0/3(P) Gi4/0/3(P)
switch#show running-config interface GigabitEthernet 3/0/3
Building configuration...
Current configuration : 172 bytes
interface GigabitEthernet3/0/3
description myserver, eth0
switchport access vlan 20
switchport mode access
channel-group 2 mode active
spanning-tree portfast
end
lansw01#show running-config interface GigabitEthernet 4/0/3
Building configuration...
Current configuration : 172 bytes
interface GigabitEthernet4/0/3
description myserver, eth1
switchport access vlan 20
switchport mode access
channel-group 2 mode active
spanning-tree portfast
end
switch#show running-config interface port-channel 2
Building configuration...
Current configuration : 82 bytes
interface Port-channel2
switchport access vlan 20
switchport mode access
end
The /etc/network/interfaces of my Debian machine looks like this:
auto lo
iface lo inet loopback
auto bond0
iface bond0 inet static
address 192.168.1.xxx
netmask 255.255.255.0
gateway 192.168.1.xxx
dns-nameservers 192.168.1.xxx
dns-search xxx.xxx.xxx
bond-mode 4
bond-miimon 100
bond-downdelay 200
bond-updelay 200
bond-lacp-rate 1
slaves eth0 eth1
This setup seems to work well. But I'm wondering that there is nothing with "trunking" in my setup. Would you like to give me your opinion about this?
Thanks a lot and many greets

VLAN trunking from Cisco Catalyst 3750 to Cisco SF300-48P issue and related
Hello expert,
I'm having difficulties to configure VLAN trunking between Cisco Catalyst 3750 switch with Cisco SF300-48P switch and my workstation unable to get any DHCP IP from our DHCP server via Cisco SF300-48P switch. Below is the snippet of configuration on both switches:
[Cisco Catalyst 3750 Switch]
interface GigabitEthernet1/0/45
description NCC-CC-1stFlr
no switchport trunk encapsulation dot1q
no switchport trunk allowed vlan 101-103
spanning-tree portfast
[Cisco SF300-48P Switch]
interface fastethernet48
spanning-tree link-type point-to-point
switchport trunk allowed vlan add 101-103
macro description switch
!next command is internal.
macro auto smartport dynamic_type switch
interface fastethernet29
switchport mode general
switchport general allowed vlan add 103 tagged
switchport general pvid 103
Are these are correct? Kindly advice!
Thank you very much!
Regards,
AlexHi Alex,
for the trunk port on Catalyst on port GE 1/0/45, we need to enable the trunk and for on encapsulation dot1q because this catalyst model is ISL capable also and the SF300 working only with Dot1q Encapsultion
The configuration on catalyst should :
#config terminal
#interface Gi 1/0/45
# switchport encapsulation
#switchport trunk encapsulation dot1q
#switchport mode trunk
#switchport trunk allowed vlan 101-103
#spanning-tree portfast
For SF300 the port trunk it looks fine but for the port where the PC should receive an IP address
#interface fastethernet29
#switchport mode access
#switchport ccess vlan 103
Please let me know after this configuration
Thanks
Mehdi

My Blu-Ray player has a USB input but it doesn't have an HDMI input. Can I connect my Apple TV to the Blu-Ray using an HDMI/ USB adapter? It would allow me to run the audio through my stereo. Thanks to all for your help.
Can I connect my Apple TV to the Blu-Ray using an HDMI/ USB adapter?
If you can find such a thing. I really doubt that exists since USB is a data connector not a video connector.
would allow me to run the audio through my stereo.
That would depend on this adapter. -

Cisco Catalyst 3750-X or 3560-X Series Switches
Recently, our company was deciding to buy Cisco switches, but they just tell the requirements and I finally focused on two kinds of switches, Cisco Catalyst
3750-X or 3560-XSeries Switches? Who can tell me, tnx in advance.As I read a blog recently, it listed the specific differences between Cisco 3750-X and 3560-X, except for the common features of Cisco 3750-X and 3560-X, Cisco 3750-X can also offer-- Cisco StackPower technology: An innovative feature and industry first for sharing power among stack members;
Cisco StackWise Plus technology for ease of use and resiliency with 64 Gbps of throughput;
Investment protection with backward compatibility with all other models of Cisco Catalyst 3750 Series Switches.
And made a more detailed comparison between the two products, for ur reference. -
Catalyst switch hangs when connecting via console port
Hi,
I've just started work for a company - they have no network documentation or knowledge of their current set-up whatsoever.
For the LAN in the office they have Cisco Catalyst WS-C3524-XL switches. But it doesn't seem like these are even configured with an IP address for management purposes.
So, I thought I would connect via a console cable to have a look at their configurations and also to investigate some performance problems some users were having on the LAN.
BUT - when I connected to the console cable, all the switch LEDs stopped flickering happily and went solid and everyone in the office lost their network connectivity! (I wasn't popular!)
Rebooting the switch with the console port still connected had no effect - the LEDs remained solid and there was no network connectivity. However, when I removed my console cable, everything started working again!
Does anyone have any ideas a) what can have caused this and b) how I can resolve this problem and connect to the switches without disrupting all the other users!
Note: I subsequently connected to a spare WS-C3524-XL switch using the same laptop and same console cable without any problems.Hi,
thanks for the response.
no, I can't login to the switch(es) at all. There seems to be no response from hyperterminal at all. (Then I noticed that the LEDs had gone "solid" and that everyone started to complain they had lost network connection!)
Even when I powered off and powered on the switch with the console port still connected, nothing appeared on the hyperterminal screen.
However, as mentioned, I'm able to connect to one of our spare switches using the same settings, same laptop, and same console cable - so I guess that would rule these things out as being the cause?
Its definitely a strange one, especially as it seems to be affecting all 3 of the live switches! -
Cannot connect to internet on ipad mini need to use 'other network' please help
cannot connect to internet need another network as haven't password
The Other Network option is so you can connect to a Wi-Fi hotspot that might have its name hidden. Other Network gives you the oppertunity to type the name of the hidden Wi-Fi hotspot so the iPad can see it.
If you are looking for a Wi-Fi hotspot to join, but can not because you do not have the password to join that network, you will need to ask the hotspot's owner for permission and a password before you can join.
If you have internet in your house and you want to connect your iPad Mini to the internet, you will need a wireless router or access point. Ask your internet provider, they may already have that available for you and it would be a quick setup for them.
Good luck,
