Configuring Packet Slicing

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 and Broadcom TD3 platforms

The packet will be truncated beginning at the Ethernet header

NVIDIA Packet Slicing feature

Packet Slicing "truncate" configuration to be applied only on tool ports

Reference

Example

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

Broadcom TD3 Packet Slicing feature

Note: TD3 platforms support only fixed-byte payload truncation; they always egress 192 bytes after truncation, for both IPv4 and IPv6 traffic

The feature is supported only in BCM ADV License
Supported in all BCM TD3 devices - Dell5248, 5232, DS2000, DS1000, EC7326, EC7726, EC5835, DS3000
A maximum of 4 truncate(packet slicing) config is supported.
An interface cannot be configured as both a packet-truncate destination interface and a flow tool port, override-to port
An interface cannot be configured as both a packet-truncate destination interface and tunnel interface
