expectedIPv4FragThreshold

Value Type

decimal

Default Value

1500

Description

This testvar specifies the total IPv4 length, in bytes, at or above which the DUT is expected to fragment IPv4 packets it forwards from the LAN to the WAN.

Set this testvar to match the WAN MTU configured on the DUT. The IPv4 fragmentation tests in the module frag.tcl use this to size the packets they send and to validate the DUT’s fragmentation behavior. The tests that send packets larger than this threshold are skipped unless it is smaller than the LAN MTU.

This testvar was added in CDRouter 16.6
