Hi All ,
At my customer place I need to replace existing access switch ie cisco 4507R (End of life switch) with cisco 4948E switch.
DBL is enabled on 4507R and below is the QoS part of cisco 4507 R switch (bootflash:cat4500-ipbasek9-mz.122-31.SGA9.bin ).
qos dbl
qos map dscp 24 25 26 27 28 29 30 31 to tx-queue 4
qos map dscp 32 33 34 35 36 37 38 39 to tx-queue 4
qos map cos 3 to dscp 26
qos map cos 5 to dscp 46

Lan uplink ports on cisco 4507 R connected to Core switches which have below qos parameters.

new 4948E switch does not support auto Qos , it has bootflash:cat4500e-entservicesk9-mz.122-54.SG.bin on it.
Somebody can tell me QoS commands which can be enabled on 4948 E as similar to cisco 4507 R switch.
For voice server its mandatory to have QoS on the port.
Many Thanks.
Thanks ,
