cisco IP phone cp-7811 not getting DHCP ip address

[AB_10]

• cisco IP phone cp-7811 not getting DHCP ip address in one Catalyst 9200 switch the same phone can get IP with other 9200 switches

  I have been checked everything correctly configured

  !
  interface GigabitEthernet1/0/3

  switchport access vlan 998

  switchport mode access

  switchport voice vlan 102

  spanning-tree portfast

  end
  !
  CDP is enable

  DHCP is working with option 150

  any idea what is maybe wrong ?
  and is there anything I can do about it?

• Note: when i tried other cisco phone model “cisco 8845” it work fine with no problems
  Issue seems with cp-7811 only

Reboot the switch. 

What firmware is the switch/stack running on?

On cat 9200 what IOS running ? is this new switch ever worked for this Phone or working before ? or migrated to Cat 9200

if the same Phone working on other Cat 9200, then i will compare the IOS version, configuration and dhcp scope options.
