hi
Case 1
---------
I have some queries on Port ligth indication on Switch 2960 . I have connected on port 0/48 & 0/49 Firewall( Check Point) IN & OUT interface ,both the ports are up and working , but when seen at ports lights its continuously blink amber & green and when seen on Switch Logging port is also not flapping or going down ..
Command at Both 0/48 & 0/47 are
switchport mode access
switchport access vlan XYZ
spanning-tree portfast enable.
pls suggest on this
Case 2

On same switches I have connnected the unmanaged Third Party Switches Uplink in Access mode , its also working but on that port also I am getting same port blink indication , but port is not going down

From the configuration which u have given,
this could be a problem due to bpduguard not being enabled.

hi thanks
I do have enable and tested on the network but since the client have more than 50 unmanaged switches in netwoork and at DC I am using only Three Cisco 2960 Access Switches with Core 3750 , with BPDUGruad Enable on accessport affects the ping response in local lan , but if I remove the Bpduguard its work fine .... should i use bpduguard filter on interface

Sounds to me like a port duplex miss-match. try hard setting the duplex on both ends.
