Catalyst 2950 series

Hello everybody,
I have a Cisco Switch, model WS-C2950C-24 with the IOS version 12.0(5.3)WC(1).
I have created two VLANs, so I have trying to assign one Ethernet port to those VLANS,
I saw, this option is not avaliable. Switch(config-if)# switchport mode multi vlan [#], [#]. (this command does not exit).
When I typed switchport mode ? , It appears just access and trunk,
Could you help me to find a command to assign one port to several VLANs.?
Thank you.
Best Regards,

2950s do not support multi-VLAN ports. You need to make it a trunk if you need to pass more than one VLAN over a link.
You are seeing it in parser because you are running ancient 12.0 code(which also runs on XL series which support multivlan ports).

CATALYST 2950 SERIES - CLEAR OPT TABLE & DISABLE CASH

I have 2 cisco switches model - catalyst 2950 series, i recently had an network issue regarding an ip conflict with one of my member servers, after being on the phone with microsoft support for 6 days, we were able to resolve the problem by locating the correct mac address and clearing the "OPT table on the switches" by unplugging and replugging the power cord. In order to prevent this from happening again, Microsoft had asked me to contact cisco and ask the following questions, " Are these swiches managable via the gui? and we also need to make sure that the "Arp Cash is disabled on the switches" can anyone help in this matter? Thanks in advance.

Catalyst 2950 Series - Monitoring Port

Do the catalyst 2950 series have a port that can be used to connect a device that is designed to monitor all traffic on the switch - we are looking to install Webspy to track network & internet usage. The Sentinal product would best be connected to the switch where it can record all traffic - it needs a monitor port or some such equivalent.

Hi,
The 2950 does indeed support that - the functionality is called Switch Port Analyzer (SPAN). The following link has details on how to configure it:

Help with Catalyst 2950 G

Hi,
I have a doubt about the Catalyst 2950 series, i need to pass both IP and OSI traffic trought a 2950 switch. Is it supported?
Thanks

The 2950 is a layer2 switch. Anything carried over ethernet will go, no matter which layer3 protocol is used.

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

Password reset on a Cisco Catalyst 3550 series

We have a Cisco Catalyst 3550 series, and we don't have the password to gain access to the switch through a web browser. My question is if I reset the password using Hyper-terminal, does changing the password affect any vlan or fiber optic settings that I should know about. Or does resetting the password changes our switch to factory settings?

Hi,
The password recovery procedure for your switch is described in this document:
http://www.cisco.com/c/en/us/support/docs/switches/catalyst-2950-series-switches/12040-pswdrec-2900xl.html
If you follow the instructions in the document exactly, you will retain the original configuration - you just rename the configuration file so that it is not loaded when the switch boots up. However, you will still be able to display it after the switch boots up using the more flash:config.old . Eventually, you can even load it into running-config using copy flash:config.old running-config command. At that point, the old passwords will be brought back but because you already are in the privileged EXEC mode, you can change them and save the updated configuration.
VLANs should not be affected as long as you do not delete the vlan.dat file located in FLASH. Fiber optic ports should not be affected as long as you are using original Cisco GBICs. If you're using 3rd party GBICs, it may be necessary to enter the service unsupported-transceiver hidden command in the global configuration mode before they get recognized.
Good luck!
Best regards,
Peter

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.

POST error Catalyst 2950

I have a Catalyst 2950 series 12 prt. switch. When the switch is booting I receive the following error: "00:00:13: POST: Packet DA mismatch on port: 9"
What does this message means? Can I still use this port?
Kind regards,

This is part of the power on self test(POST).
The switch sets the interface to loopback and sends
a packet. If anything is wrong or changed with
the packet then you get an error. In this case
the DA (destination address) was changed on
the received packet. I assume since this is a
switch they are referring to the layer2 address.
I would think this would indicate a possible hardware
failure.

DHCP on Cisco Catalyst 2950 Switch

Hello
I need to configure my cisco catalyst 2950 series switch in order to act as DHCP server for devices connected to its ports.
Please say me, how to do that ?
Thank you
Narek

Please find the sample DHCP configuration for one of the VLANs.
Interface Vlan1
description Cisco DHCP
ip address 10.10.2.1 255.255.255.0
ip dhcp pool cisco
network 10.10.2.0 255.255.255.0
default-router 10.10.2.1
domain-name mydomain.com
dns-server 10.10.2.10
netbios-name-server 10.10.2.15
lease 7
A 24 hour lease is the default if left out and the netbios-name-server is WINS in the Windows world.
If you want to use DHCP server for other VLANs as well create similar DHCP pools and assign the DG to the corresponding VLAN interface IP.
HTH, rate if it does

Catalyst 2950 Standard or Enhanced Image

Hello,
can someone, please, tell me the software difference between Catalist WS-C2950G-24-EI and WS-C2950C-24. The product adviser is not very clear about it.
Thank you in advance.
Cordially.

Hello Maxime,
basically, the EI has more advanced QoS and Security features.

How to remove the WiSM2 from the Catalyst 6500 series switch?

Hello, can you explain to me how to safely remove the WiSM2 from the Catalyst 6500 series switch?
According to the documentation "Catalyst 6500 Series Wireless Services Module 2 Installation and Verification Note":
To remove the WiSM2, perform these steps:
Step1     Shut down the module by one of these methods:
In privileged mode from the router prompt, enter the hw-mod module mod shutdown command. NoteIf you enter this command to shut down the module, you must enter the following commands in global configuration mode to restart (power down, and then power up) the module:
Router# no power enable module modRouter# power enable module mod
If the module does not respond to any commands, press the SHUTDOWN button located on the front panel of the module.
Step2     Verify that the WiSM2 shuts down. Do not remove the module from the switch until the POWER LEDis off.
But, in the case of Step1 (1st methods) I do not see a option "shutdown" in the command "hw-mod module 3"...
All I prompted to enter is:
c6500#hw-module module 3 ?
boot           Specify boot options for the module through Power Management Bus control register
reset          Reset specified component
simulate Simulate options for the module
Is it hidden options? IOS version of c6500 is 12.2(33)SXJ1
In the case of Step2 (2nd methods) there is not any button on the front panel of the module?
And yet, it is better to remove the module configuration manually or use the command module clear-config prior to removing the module?

Good catch.
Which one is true, will get back to you on this if i've something soon.
http://www.cisco.com/en/US/docs/wireless/module/wism2/installation/note/WiSM_2.html#wp34727
The above link is procedure to remove wism2. This procedure doesn’t look like wism2 is hot swapable.
http://www.cisco.com/en/US/docs/wireless/module/wism2/installation/note/WiSM_2.html#wp34621
All modules, including the supervisor engine (if you have redundant supervisor engines), support hot swapping. You can add, replace, or remove modules without interrupting the system power or causing other software or interfaces to shut down. For more information about hot-swapping modules, see the Catalyst 6500 Series Switch Module Installation Guide.

Cisco ISE and Catalyst 2950

Hello!
Please, could you help me? Is it possible to install ISE on Catalyst 2950? In Component Compatibility Guide
http://www.cisco.com/en/US/docs/security/ise/1.0.4/compatibility/ise104_sdt.html
Catalyst 2950 only support 802.1X and VLAN.
At first I need to know about VLAN change(from resticted to corporate). Is Catalyst 2950 support it?
Thaks for help!

this would let both user and machine authenticate. for"5434Endpoint conducted several failed authentications of the same scenario" check Suppress Anomalous Clients option. This issue comes in to picture when endpoint attempts a couple of failed authentications and if Suppress Anomalous Clients option with Reject Requests After Detection is enabled then ISE Policy nodes protect themselves from overwhelming numbers of authentication requests by sending an immediate reject for suppressed clients as opposed to processing all the steps in a normal authentication. So if that user did some authentication failure, he will be locked for 1 hours (bydefault).

Cisco Catalyst 2950/2960/3750 Multicast Traffic Preference

Hello all,
we, as a student company act as an ISP for university dormitories. We would like to (if it's possible) deploy QoS to prefer multicast traffic over all other types of traffic.
Devices used in network:
Acces layer: Cisco Catalyst 2950, 12.1(22)EA14
Dristribution layer: Cisco Catalyst 2960G, 12.2(58)SE1
Core layer: Cisco Catalyst 3750G, 12.2(52)SE
Do you see any possibility to solve this with these devices? We have almost no experience with QoS, therefore any help would be greatly appreciated.
Thanks in advance.

Hmm, I think it should be doable although the 2950s, if non-E variants, are especially weak in QoS features. I.e. those might create some issues.
With the 2960G and 3750G, you often will create problems when you enable QoS because QoS, by default, allocates its buffers resources for 4 egress queues per port rather than using all for 1 egress queue per port. However, this can be countered by QoS parameter tuning, but that takes some QoS expertize to match to your traffic and your overall QoS policy.
