Usage Guidelines

If the content security service is configured in the security policy for fragmented packets, the fragmented packets are sent to the IAE for processing. The IAE establishes a session and reassembles the fragmented packets. Using the display fragment-reassemble session table command, you can view the packet fragment reassembly information in the IAE session table.

Example

# Display IPv4 packet fragment reassembly information in the IAE session table.

<sysname> display fragment-reassemble session table
