If any of the built in services are in use, the administrator can also click on the advanced button to modify the built in services TCP/UDP port numbers if required. Special TCP/UDP class: This allows the administrator to set a low or high priority to the port numbers shown in the Special UDP/TCP Port Selection section. Default Class (All other TCP/UDP Ports): This allows the administrator to set a low or high priority to all other port numbers not shown in the Special UDP/TCP Port Selection. Port: Select the port you wish to configure your Special TCP/UDP port classifications for, if you wish to configure all ports at the same time, select all from the drop down box. Special UDP/TCP Port Classifications: The following lists the ports that are used for all 6 built in services: - Down Prioritise web browsing, email, FTP and news: 80, 280, 443, 25, 110, 20, 21, 69, 119, 2009 - Prioritise IP Telephony (VoIP): 1718, 1719, 1720 - Prioritise iSCSI: 3225, 3260, 3420 - Prioritise web browsing, email, FTP and news: 80, 280, 443, 25, 110, 20, 21, 69, 119, 2009 48 Alloy Computer Products Pty Ltd Copyright ©2006 GSM Series User Manual - Prioritise Streaming Audio/Video: 2979, 1755, 7070, 7071, 554, 8000 - Prioritise Databases (Oracle, IBM DB2, SQL, Microsoft): 66, 1571, 1575, 523, 118, 156, 3306, 1232, 1433, 1434 Fig. 3-22 Advanced Mode Fig. 3-23 Simple Mode 49 Alloy Computer Products Pty Ltd Copyright ©2006 GSM Series User Manual Function Name: IP Diffserve Classification: Function Description: The GSM Series switches allow the administrator to configure priority levels based on the 6-bit field in the DSCP of the IP packet. The 6-bit field allows a total of 64 different traffic classes in which you can set a High or a Low priority. Parameter Description: Diffserv: Displays the 64 traffic classes in which a priority level can be assigned. Class: Set a High or Low priority level to any of the 64 different traffic classes.

SNMP Configuration Any Network Management System (NMS) running the Simple Network Management Protocol (SNMP) can manage any Managed device equipped with an SNMP agent, provided that the Management Information Base (MIB) is installed correctly on the managed devices. SNMP is a protocol that is used to govern the transfer of information between SNMP managers and agents and traverses the Object Identity (OID) of the Management Information Base (MIB), described in the form of SMI syntax. The SNMP agent is running on the switch to respond to requests issued by an SNMP manager. The GSM Series switches allow the administrator to turn the SNMP agent on or off. If SNMP is set to “Enable”, the SNMP agent will be started. All supported MIB OIDs, including RMON MIB, can be accessed via an SNMP manager. If SNMP is set to “Disable”, the SNMP agent will be deactivated, the related Community Name, Trap Host IP Address, Trap and all MIB counters will be ignored. Fig. 3-25 Function name: SNMP Configuration Function description: This function is used to configure SNMP settings, community name, trap host and public traps as well as the throttle of SNMP. A SNMP manager must pass the authentication by identifying both community names then it can access the MIB information of the target device. Therefore, both parties must have the same community name. Parameters description: SNMP: Is used to Enable or Disable the SNMP Service. Default: Enable 51 Alloy Computer Products Pty Ltd Copyright ©2006 GSM Series User Manual Get/Set/Trap Community: The Community name is used as a password for authentication to the Network Management software that is being used.
