Hi,

  Please note that I have created a new VLAN in 4507 and configured in HSRP. B

 The newly created VLAN interface (vlan 16) is in shutdown. All other VLAN created earlier are up.

CORE 1

interface Vlan16
ip address 10.0.16.2 255.255.255.0
standby 16 ip 10.0.16.1
standby 16 priority 150

interface Vlan16
ip address 10.0.16.3 255.255.255.0

Hello @Arif Rafi,

Does the VLAN 16 member of an Active Trunk port ?

Hi,

 I have configured the trunk port on the interface gigabitEthernet2/45 - but not active.

 @Arif Rafi 

like @MHM Cisco World has just said, does the trunk port UP ?

Thanks.

Hi,

Trunk port is not up - only configured the port.

VLAN must be allow in trunk and the trunk must be UP 
VLAN must add to SW via 
vlan x <<- add this command

Hi,

VLAN allowed in trunk port gigabitEthernet2/45. But it is not up. Uplink fibre  is not connected to the access switch.

Is there any way to check the interface is OK. ( I tried to ping from core switch itself to the new SVI - but not pinging.

Regards,

AMR
