cisco vendor id for dhcp issue

[shohamshalom]

Hi,

my costumer envirement include 3 phone vendors (alcatel, avaya, and now cisco)

alcatel vendor Unique id is 3a02  when configure the dhcp scope ( all the port here configure as trunk with defualt data vlan, so when the alcatel/avaya phones connected they pool data vlan and according to the vendor id recive voice vlan of specific vendor.

in that way , u can replace different phone vendors without changing anything in the swith ports

i try to add the option 150 scope for the cisco phones but cant find the cisco vendor id (should be Unique for cisco vendor )

so please assist me to find cisco vendor id ....

Cisco are wonderful, in that they don't have a consistent name in their products. To recognise Cisco phones on my DHCP server I currently have:

class "cisco-phones" {
    match if substring (option vendor-class-identifier, 0, 28) = "Cisco Systems, Inc. IP Phone" or
      substring (option vendor-class-identifier, 0, 28) = "Cisco systems, Inc. IP Phone" or
      substring (option vendor-class-identifier, 0, 27) = "Cisco System, Inc. IP Phone" or
      substring (option vendor-class-identifier, 0, 19) = "Cisco Systems, Inc." or
      substring (option vendor-class-identifier, 0, 33) = "Cisco Systems Inc. Wireless Phone" or
      substring (option vendor-class-identifier, 0, 6) = "ATA186" or
      substring (option vendor-class-identifier, 0, 12) = "CISCO ATA190"

...

Then there are the OUIs you have to use for VG gateways as they don't provide a vendor-class-identifier attribute.
