Doesn't BLE support pairing/bonding? cc2541

Hi,

Can anyone please tell me if BLE supports pairing/bonding concept? I have searched different FW available in ble stack but none of the fw has defined callback for pairing/bonding. Its mentioned that its not used by application

// GAP Bond Manager Callbacks
static gapBondCBs_t simpleBLEPeripheral_BondMgrCBs =
{
NULL, // Passcode callback (not used by application)
NULL // Pairing / Bonding state Callback (not used by application)
};

I was also expecting the same but why in BLE stack callback function are not defined?
What's advantage of pairing over normal connecting?

If the two devices, central and peripheral, are paired then whatever data exchanged between them will be in encrypted format. So it prevents the sniffing attack.

1)Where can i find code for pairing? Doesn't TI stack provide code for pairing?
2)I want to know advantage of pairing process after peripheral disconnects. Once paired, will central get connected automatically each time peripheral is power recycled?
