Hello Saroj,

To enable Jumbo Frames on the 5548/5596 refer to this document:

http://www.cisco.com/en/US/docs/switches/datacenter/nexus5000/sw/qos/513_n2_1/b_Cisco_Nexus_5000_QoS_Config_Guide_513_N2_1_chapter_0101.html#con_1150612

Keep in mind that when you do a "show interface " it will continue to show the MTU is set to 1500 regardless of configuration.  You need to look at "show queuing interface ".

Hope this helps!

Dave
