Add d-link DES-1210-28p switch to cisco network??

[Ivan Marinovic]

Hi,

In our organization we have only cisco switches.. 6509 core, 3750 as distribution, and 2960 as access switch... now we receive d-link 1210-28p switch.

is it possible to add d-link DES-1210-28p switch on cisco 2960 switch and to have voice vlan and other vlan??

On cisco switch i configured port:

interface FastEthernet0/22

switchport trunk allowed vlan 8,24

switchport mode trunk

switchport nonegotiate

switchport voice vlan 8

switchport port-security maximum 24

switchport port-security aging time 10

switchport port-security violation restrict

switchport port-security aging type inactivity

ip arp inspection limit rate 500

srr-queue bandwidth share 10 10 60 20

priority-queue out

mls qos trust device cisco-phone

mls qos trust cos

auto qos voip cisco-phone

spanning-tree portfast

spanning-tree bpduguard enable

service-policy input AutoQoS-Police-CiscoPhone

and on dlink i add two vlan 8 (for voice) and 24 for network...

But it is not working....

when cisco port is set to access i can go on internet but voice is not working!!

any suggestion??

regards,

IVan

Hello Ivan,

from your qos configuration it looks like you have Cisco IP phones

with default settings cisco IP Phones uses Cisco CDP to discover the voice Vlan, you should verify if:

your switches both the C2960 and the D-link supports LLDP-MED that is the standards based equivalent of CDP

if the CUCM version or call manager express version allows to configure the phones to use LLDP-MED and so on

see

and then also for CUCM ot CUCME

the following link provides information on CDP vs. LLDP-MED

using google search you can find:

Probably, you may be able to set the voice vlan manually on the phones as an alternate way to all above

Hope to help
