Severity: 4-Minor


If you have a HSB platform that does not have HW DoS features then bad TCP/UDP/IP checksum pkts could cause a performance drop.


Performance will not be optimum.


-- Platform which does not have HW DoS. -- A very high number of bad checksum packets are received


Create a file with name 'tmm_init.tcl' in '/config' containing the following lines: HSB::netc_ipcsum_drop yes HSB::netc_l4csum_drop yes And then reboot.
