The SSR8000 (Smart Switch Router) listening on tcp ports 15077 and 15078, this ports are used for MPS code. For more information about ATM MPOA Server (MPS) : http://www.enterasys.com/support/techtips/tk0659-9.html Sending few packets on tcp ports 15077 and 15078 against SSR8000 with firmware E8.2.0.0, and E8.3.0.4 the system go down. Test 1 From Linux-pc (IP 10.2.1.2) to SSR " nmap -PT 10.2.1.1 -p '15077-15078' " single scan Result No Crash Test 2 If we do two test “ nmap -PT 10.2.1.1 -p '15077-15078'” in same time or in few time Result CPU at 1% System go down Solution Temporary solution: ACL for denies any access to ports 15077 15078 from any interfaces Definitive solution: Upgrade the firmware of SSR to 8.3.0.10 or greater Notes probably the problem is present on other versions with firmware previous to version 8.3.0.10 Marco mail: m.mella@saritel.it
