Re: Questions on Cisco SF300-24P

Actually the end of sale date on the 7961 phones was January 19 2010.

http://www.cisco.com/en/US/prod/collateral/voicesw/ps6788/phones/ps379/end_of_life_notice_c51-520685.html

More specifically what I was referrring to was being able to use 802dot1Q encapsulation so these switches could work together with 2800 and 2900 switches for multiple vlans per interface. For that matter they wont even work with an ASA5505 in a trunked environment.

Re: Questions on Cisco SF300-24P

7960 and 7940 which is what was discussed in this post was EOL'd back in 2002:

http://www.cisco.com/en/US/prod/collateral/voicesw/ps6788/phones/ps379/prod_end-of-life_notice09186a0080088a2c.html

802.1Q encapsulation works with all standards-based products, including the ones you've mentioned. Make sure that you set the encapsulation to "dot1q" on the router side:

switchport trunk encapsulation dot1q

Contact the Support org and they will help you through getting this to work.

BTW, the reason why you're not seeing the phone as an LLDP Neighbor is because those older phones do not support LLDP-MED. You have to set the voice VLAN on the phone manually.

Questions on Cisco SF300-24P

This is an old thread, but for the benefit of anyone searching, a firmware release has been made that allows the 200 and 300 series Small Business switches to support Cisco Inline Power, aka pre-standard POE.

https://supportforums.cisco.com/docs/DOC-18337

This means that those switches will indeed power the CP-7940/CP-7960 and the CP-7940G/CP7960G, even though they do not support the 802.3af standard. A number of older third-party switches also support CIP, but there is no list that I have found that specifies which ones do and do not. The CP-7941/CP-7961 that tahequivoice referred to are different phones (though they look nearly identical) that do support 802.3af out of the box.

Please note, however, that the updated firmware has not been released for all 200 and 300 series switches. As the comments at that link mention, the firmware has yet to be released for the SG200-08P, among others.

As for throwing these phones out because they are "kinda old"? That makes no sense and would be extremely wasteful. The Panoptic adapters mentioned seem to be available for $27.00 each, which really might be the best long-term solution, as it makes them 802.3af compliant (though I have never used one).

Questions on Cisco SF300-24P

All 300 series switches and all 200 series switches support Cisco Inline power except for SG200-08P and the 200E models.These models use a different chipset and software and do not support this capability.

Thanks,

Ivor

The issue I think has nothing

The issue I think has nothing to do with the model of phone am using cp3905 and still cannot get what I want. It will pick the untagged vlan ip and give the system same. What I want is that the phone pick its voice vlan and give the pc connected to it data vlan. I have tried all the suggestions and still cannot get it working as I want. Not that the phone does not work with the data vlan but I want it to take its own vlan.

Hello,Im sorry you haven't

Hello,

Im sorry you haven't been able to resolve this issue in so long. 

Mid you are already using the port as trunk with VLAN 10 untagged and 20 tagged then the issue is not on the port but somewhere else on the configuration. 

The first step is probably gathering all the network topology showing the voice devices, phones, pbx and such. It will be important to show the ports evetythibG is conneCted to showing the Vlans and port configuration. 

I hope this helps.

here is my layer 2 switch

here is my layer 2 switch configuration.

I can connect the phone now and it will get voice vlan but the PC connected to the phone or the port cannot get data vlan.

Actually have been able to resolve the issue by the global command no lldp run and interface lldp med disable command.
