Configuring Packet Slicing

Truncation and Load Balancing

You can use packet truncation, which is a unique capability available only on NVIDIA platforms, to truncate the packets which are sent to the tool. This helps tools reduce the storage capacity needed for saving packets for future analysis. It truncates the packet for the given offset.

This feature is only supported on the NVIDIA platforms

The packet will be truncated beginning at the Ethernet header

Reference

Command	truncate <offset value> no truncate
Description	Truncate packets after offset
Parameters	Offset-value – multiple of 4 within 48 to 4088
Mode	INTERFACE

Example

pbnoscli# configure terminal 
pbnoscli(config)# interface ethernet Ethernet4/1
pbnoscli(config-if)# trunc    
  truncate              Truncate the packet
pbnoscli(config-if)# truncate 64

You can verify the configuration by using the command(s) below:

pbnoscli# show interface npb Ethernet4/1
