2 catalyst 3750G interVLAN ios 12.1

Hello,
I got a step by step guide on how to interVlan this 2 switches but I am running into a problem.
when I create the VLAN ID 1058 (set by isp) it does not show up in my show vlan. therefore I cannot assign ports to it. if I create a VLAN ID 300, it shows up and I am able to continue my installation. Does this switch support extended vlan ID or am I missing something extra.
thanks

Hi,
Extended Vlans are supported on 3750. You have disable VTP on the switch or to set it up to trasparent mode before setting up the extended range vlans on it.
conf t
vtp mode transparent.

EEM Scripts on a Catalyst 3750G

Does anyone know if I can run EEM scripts on a Catalyst 3750G switch? If so, what version of IOS do I need to make it work?
Thanks!

Joseph,
I want to create a simple EEM script on a Catalyst 3750G running ipservices IOS on it. All I want to do is monitor interfaces GigabitEthernet 1/0/3 and GigabitEthernet 1/0/4. If either of these interfaces go down, I wan the EEM script to shutdown interface GigabitEthernet 1/0/26. Here is what I put together so far. I haven't tried it yet, but do you think this will work?
Thanks!

Upgrade of Cisco Catalyst 3750G 24T

Hi,
I want to upgarde a Cisco Catalyst 3750G 24T because I can't see the web interface.
I checked the documentation and see a lot of videos on the net.
I downloaded the new firmware c3750-ipbasek9-mz.122-55.SE9.bin
I downloaded a tftp software and putted my ip adress on it.
I connected the Cisco by console and launched Putty by serial.
I sended en for grant my right access.
I sended my password
and tapped :
copy tftp: flash:
it asks TFTP Ip, i gave it
10.0.0.45
file name
i gave it
c3750-ipbasek9-mz.122-55.SE9.bin
and after It sended me when it must put it and i sended the same name.
c3750-ipbasek9-mz.122-55.SE9.bin
And then It works few seconds and the cisco says error ... time out.
I've tested with W8, W7 and a lot of tftp server. I disabled my firewall.
The password is the default password. It is a problem ?
Can you help me ?
Thanks
Nicolas

Copying only the BIN files into the appliance will NOT help. You still won't be able to use the web interface.
You need to download the full IOS, the filename ends with TAR. To unpack the file into your appliance you use the command "archive download-sw tftp://<TFTP IP address>/filename.tar".

How I can force to Catalyst 3750G to work like SLAVE

Hi,
Help me, how I can force to Catalyst 3750G to work like SLAVE, I can't find the command..

Hello Friend
You have to set the slave switch's priority to be lower than the master switch.

Does Catalyst 3750G have IPv4-IPv6 translation feature ?

we developed an application with IPv4 and it is being put on IPv6 based network to talk to the client application. We have Catalyst 3750G and want to enable IPv4-IPv6 translation. Does 3750G have such feature ? If yes, how can we use it ?

I think not. Routers have that capability
When enabling communications between IPv4 <-> IPv6 you need v4-v6 Tunnels and/or translations(NAT) w/c can only be done in routers

What is different between Cisco Catalyst 3750G-24-TS-S 1U and Cisco Catalyst 3750G-24-TS-S 1.5 U, Other than Size( Any other technical difference)

Hi Kali ,
Size only matters when compare both the switches.

Catalyst 3750G-12S-E upgrade latest IOS images

Hi to all,
I've a question regarding the Upgrade to the latest IOS image since this 3750G model is one of the latest which have on-board only 16MB of Flash...
I've seen that latest IOS .tar images with SSH and Web Device are about 15.5MB or more, so I've tried to install one of these with archive /overwrite feature without succeeding...then tried to free up all the flash space needed but I've had the same problem!!!
How should I proceed??? Are this image only for other 3750models????
Thx
Omar

I ran into this same problem on my 3750G switches. Use the lm image for the switch and use Cisco's Network Assistant for managment or go command line.
http://www.cisco.com/en/US/docs/net_mgmt/cisco_network_assistant/version5_0/release/notes/OL12210a.html#wp670016
Catalyst 3750 or 3560 switches with a 16-MB flash memory can experience problems due to flash memory constraints, especially if they are using larger size images, such as c3750-ipservicesk9-tar, c3560-ipservicesk9-tar, c3750-ipbasek9-tar. or c3750-ipbasek9-tar images. These are the affected switches:
Catalyst 3560: WS-C3560-24PS and WS-C3560-48PS
Catalyst3750: WS-C3750-24PS, WS-C3750-24TS, WS-C3750-48PS, WS-C3750-48TS, WS-3750G-24T, WS-C3750G-12S , WS-C3750G-24WS, WS-C3750G-24TS, WS-C3750G-16TD
The workaround for these switches is to use the corresponding lm images, such as the c3750-ipserviceslmk9-tar or c3560-ipserviceslmk9-tar images, which require less memory. In future releases, images are expected to grow more in size, requiring more need for the lm images.

Am I doing something wrong or is it generally impossible to load an IOS via TFTP to a 3550?

I am pretty sure you can't boot from a TFTP server with the Catalyst 3550 (or any of the other standalone access switches - 2950, 3550, 3560 3750 etc). If you want to recover one you need to recover it using XModem via the console:
http://www.cisco.com/en/US/products/hw/switches/ps628/products_tech_note09186a0080169696.shtml
I used to think you had to do this at 9600-baud, however you can increase the baudrate and it only takes 10-20 minutes (I couldn't get 115200 to work but 57600 worked OK and took about 20-minutes).
You need to remember to put the baud rate back to 9600 when the image is back on as it gets stored in NVRAM and reboots etc are at the stored speed (i.e. changing it after it has booted under the line con 0 doesn't get saved to NVRAM).

Catalyst 3750G Problem

i've 2 Catalyst's 3750G in stack in core of the network.
i connected PC with Sniffer to one of the port and can see traffic from all others ports - ISA server connected to other port and i can see requests to ISA server from all clients PCs.
How to explain it and fix it?

Further investigation gave more detailed information. We have Microsoft cluster consisted of 2 servers which connected to 2 ports. They have one mac-address and that mac-address is absent in mac-address-table. I tryed to add static entries to table -
arp 10.20.0.1 02bf.0a14.0001 ARPA GigabitEthernet2/0/20
arp 10.20.0.1 02bf.0a14.0001 ARPA GigabitEthernet2/0/11
But it didn't help...
How to resolve it?

Catalyst 6509 VSS IOS upgrade

Hi,
We have a Catalyst 6509 VSS system, each chassis have 2 supervisor engines. The IOS version is 12.2(33)SXI4a. We should upgrade to 12.2(33)SXI12.
The following document mention 2 upgrade method : FSU & eFSU
http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/12.2SX/configuration/guide/vss.html#wp1170391
We can not use eFSU due to the images with release dates more than 18 months apart, so we can use FSU only. And there is some note for FSU :
Note VSS mode supports only one supervisor engine in each chassis. If another supervisor engine resides in the chassis it will act as the DFC
It make me some confuse.... What is the correct procedule to upgrade the Caytalyst 6509 VSS IOS ( each chassis with 2 supervisor engine )?
Best Regards,

Hello Jackson,
Please take a on the next post which may answered your questions:
https://supportforums.cisco.com/thread/2188244
Intrachassis Availability
The initial release of the Cisco Virtual Switching System supports only a single supervisor per chassis. If a second, or redundant, supervisor is installed in an individual chassis then the redundant supervisor will not fully boot. The redundant supervisor will stop the boot process at the ROMMON stage.
In this configuration any device connected to the chassis in a single-homed, or single-attach, manner must rely on the availability of the single supervisor. Therefore the recommendation for connecting to the VSS is to always dual-attach devices.
As a result of the single supervisor per chassis support the recovery period for replacing a failed supervisor module is undeterministic in that the recover process requires manual intervention in order to install and initialize a new supervisor in the chassis.
Beginning in the 12.2(33)SXI4 software release, Quad-Sup Uplink Forwarding is supported which allows for a redundant supervisor to fully boot Cisco IOS Software, thereby providing a deterministic recovery option for redundant supervisors in a VSS chassis.

Connect Nexus 5548UP-L3 to Catalyst 3750G-24T-E Layer 3 Switch

Please help!
Could anyone out there please assist me with basic configuration between Nexus Switch and Catalyst Switch, so that devices connected on the catalyst switch can talk to devices connected on nexus switch and vice-versa? In my current setup all servers on VLAN 40 are connected on the Catalyst Switch A as shown in the diagram below, and all desktops and all other peripherals are connected on the Catalyst Switch B. I am required to implement/add a new Nexus Switch 5548 that in the future will replace the Switch A. From now I just need to connect both switches together and start moving the server from Switch A to the Nexus Switch.
The current network setup is shown as per diagram below:
SWITCH A – this is a layer 3 switch. All servers are connected to this switch on the VLAN 40.
SWITCH B – all desktops, VoIP telephones, and printers are connected on tis switch. This switch is also a layer 3 switch.
I have connected together the Nexus 5548UP and SWITCH A (3750G) using the GLC-T= 1000BASE-T SFP transceiver module for Category 5 copper wire. The new network is shown as per diagram below:
Below is the configuration I have created in both Switches:

I made a mistake without realising and the interface e1/3 was showing "Interface Ethernet1/3 is down (Inactive)". After spending sometime trying to figure out what was wrong with that interface or switch, it turned out to be that i forgot to add the vlan 40. Now the config looks like this:

Catalyst 3500 XL IOS 12, with VoIP (2 vlan on ports issue)

hi,
i tried to setup a catalyst 3500 XL to run with VoIP.
I need on a port to TAG 2 VLAN (link to the backbone), and on the others to tag one VLAN (voice one) and untagged the data vlan.
unfortunately, through the web interfcae and through the IOS command i could not setup this configuration.
have any idea?

The uplink to the other switch where you want all the vlans tagged:
conf t
int fa x/x
switch
switch trunk dot1q native vlan 99 >> vlan 99 is a dummy vlan that is not used for any data or voice, we just use this to make sure all is tag since native vlan in dot1q is not tagged with vlan id.
int fa x/x
switchport
switchport trunk dot1 native vlan 2 >> the data vlan.

100BaseFX and Cisco Catalyst 3750G

Hi,
I need some help, I have a factory plant running some IE 3000 and Rockwell Stratix 8000 with GLC-FE-100FX-RGD transceiver to some older switches I need to replace the idea is to use Cisco 3750G, I saw in the Cisco 3750G datasheet a GLC-GE-100FX= transceiver would they work together point-to-point? what sort of connector do they use are they LC also?
The idea is to use 100BaseFX MM because of the costs, distance (800M) and the bandwith being light.
Thank You

The GLC-GE-100FX= and the GLC-FE-100FX-RGD SFPs have the same optical performance specifications, so they will interoperate across a link. The RGD SFP has a higher operating temperature range for industrial applications (per data sheet), where the IE 3000 is typically installed.
Hope this helps!

Catalyst 6500 running IOS 12.2(33)SXI6 crashed (CSCsv77354)

Hi,
Today one of our customer reported their DMVPN Hub got crashed, analyzing the crash file I found that it crashed due to
"Stack for process ACE HAPI running low" . The bug tool kit has a matching bug CSCsv77354 but the status is terminated since it is not re-producible. I dont know how shall we proceed further, shall we upgrade to SXJ IOS since this problem is not reported in that version.
May I know if any one has experienced similar crash.

Regards,

Regarding the first question, you are correct. The WAN image provides support for WAN modules, but the LAN image does not. Since your current image is IP services based, you do want to use IP services with WAN and K9 in it. example:
s72033-ipservicesk9_wan-mz.122-33.SXI14.bin
As for your second question, if you upgrade to 12.2(18r)S1, it should be sufficient to run later images like SXJ and IOS 15 as well.
As for the last question, you can upgrade from the current image directly to SXJ with no issues as long as you have enough memory and flash space. There maybe some commands that you need to redo after the upgrade but nothing significant. Make sure to have a good backup of your config.

Catalyst c3750g Cisco IOS 12.2 (25) SEE2 support SSH

I need some help configuring SSH on a 48 port Switch Cisco WS-C3750G-48TS that is running Cisco IOS 12.2(25) SEE2.
I have attempted to set it up, but I had no luck. If anyone can give me any assistance to this let me know.

Hi Mike
Based on your existing IOS level (iP Base/IP services/Adv IP services) you should upgrade your switch to one of the IOS versions given below, to have SSH:
c3750-ipbasek9-mz.12.2-52.SE - min flash 16, DRAM 128
c3750-ipservicesk9-mz.12.2-52.SE - min flash 16, DRAM 128
c3750-advipservicesk9-mz.12.2-46.SE - min flash 16, DRAM 128
Once you have your IOS upgraded, define hostname, domain name, crypto rsa key, and transport input commands on the switch to have it converted to SSH..
Hope this helps.. All the best
Raj
