Cisco Network Assistant Download

[johnfromen6]

Hi I'm new to the site. I represent a charity and have been given a Cisco WS-C2960X-48LPS-L switch. However because this is EOL there is no way I can now download the Network Assistant to manage it. I only need to do basic configuration. Can anyone who has "Network Assistant English Installer cna-windows-k9-installer-6-3-4-en.exe" let me have a link to download it - it would be much appreciated

Hello @johnfromen6 ,

Cisco Network Assistant is retired by Cisco and cannot be downloaded anymore.

Alternatively you can use the Device Manager which offers a web interface for basic configuration and management of the switch.

You would firs need the blue console cable to connect the switch to a PC using a terminal program - Putty for example.

Use the console connection to configure the management IP address (interface Vlan1), a username and password for accessing the switch, the enable secret password, a default route and then save the configuration.

See the link for detail about accessing the device using the console: https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst2960xr/hardware/quick/guide/b_gsg_2960xr.html#task_72CB30C79923477BB5C34CB02263BA65

Next step is to verify if the switch has the GUI enabled IOS image - from the console issue the command dir

You should see an output similar to this one:

If the IOS filename is similar to the one in the upper screenshot (it's a directory as specified by the d in the second column of the output), then your IOS is GUI enabled and you can access it on the IP address configured earlier on Vlan 1.

Hope this helps.

Thanks that's really helpful. I'll give it a go when it arrives. Is there a default username and password I need to access the above?

[liviu.gheorghe]

If the switch was wiped of it's config, you won't have any username and password. If the config was not wiped, then you will have to do a password recovery on the device.

And remember all the config can be done directly from the command line (CLI) so you don't need any graphical interface or tool.

Thanks LG and Rich. Just a further quick question. If I'm using my router as the DHCP server do I need to disable anything in the switch after the initial set up described by LG?

[liviu.gheorghe]

Disable anything - No.

If you have multiple vlans configured on your switch and want to have connectivity between those vlans, you will have to configure the interface connecting to the router as a trunk.

This will help if those vlans will need to get IP addresses via DHCP.

Thanks again LG

[liviu.gheorghe]

You are welcome. Glad to help.

[johnnaccarato]

Just to update you now have the switch and was able to set it up using the method described so thanks again LG.

Just one further question and it may be that I should do it under a new post. I have 3 POE devices 2 ubiquiti Access Points and a Teltonika 5G Mobile Modem in bridge mode. The switch auto detected the POE requirements of the AP's and they're working fine but nothing on the modem. The modem is powered by a Ubiquiti POE injector (24V 12W) and passive POE splitter (which came with the modem) combination. I've set one of the switch ports from auto to static using the CLI and that was accepted and saved to the configuration but it made no difference. Is it simply the case that the switch simply can't replace the POE injector to supply power to the POE splitter? Cheers John

Hard to say without knowing anything about your 5G modem.  Have you checked the data sheet and install guide for the modem.  No reason why it shouldn't work with the switch.  You'll either have to set the power level statically or if it negotiates POE then you need to enable LLDP on the switch (lldp run) and on the port (lldp receive and lldp transmit).  Usually the default auto POE settings will still work with dumb devices anyway.  Not sure what that "POE splitter" is or does.  Generally POE should be connected directly to the device consuming the power.  Maybe that splitter is only intended to be used with the power injector?

[johnfromen6]

Thanks Rich the injector is one that was supplied separately to the modem (it was made by Ubiquiti and the modem by Teltonika). The splitter came with the modem and is used in the modem's outdoor enclosure. The modem is made to normally work with a dedicated power supply however the supplied splitter is a simple Y connector which takes the ethernet cable comming up from the comms room (bearing combined data and power from the injector) and sends dc power down one strand of the Y connector to the dc input of the modem and data on the other strand to the data input of the modem.

I've just tried the LLDP commands you suggested and it has made no difference. My thinking is that the the injector supplies power whether a device asks for it or not. The switch needs to do the same otherwise the modem gets no initial power to send information back to the switch? Is it possible to do that with the switch or am I completely barking up the wrong tree?

[Rich R]

Have you tried "power inline static" and "power inline static max 15400" on the port?
I doubt it will make any difference for your case but sometimes

power inline port 2-event

can help on the port config.  But I'm now thinking this will not work ...

Take a look at https://community.cisco.com/t5/switching/poe-passive-questions/td-p/1347837
I seems "passive POE" is marketing speak for "non-standardised proprietary POE" (=borrowing some wires in the cable to send power - not actually IEEE standards based POE and not even on the right pairs) so you might need that 802.3af converter they mention.

Thanks Rich those articles are useful and leads me to believe I'm thinking along the right lines. It may be that the POE negotiation is non standard and what I need is to be able to do is set the voltage supplied to the modem by the switch (24V) manually. Is that possible?

[johnfromen6]

PS I had already set the port to static POE
