5. 4 4 1 Log Message System The software modules and submodules of the SmartCell 6A000 switch automatically generate log messages These messages are stored in the log message buffer residing in system memory Messages are conditionally forwarded from the log message buffer to two other buffers the log trace buffer and the alarm message buffer You can view log messages directly from the log message buffer However you can filter and prioritize messages by viewing them through the log trace and alarm message buffers How Log Messages and Alarm Messages Differ Alarms are log messages that are forwarded from the log message buffer into the alarm message buffer Forwarding is based on user defined filters of the error flags contained within the log messages Use the show 1ogalarmmask and modify logalarmmask commands to view and modify the Alarm Message flag settings The alarm message buffer resides in flash RAM and is non volatile For example if a switch crashes and is then rebooted you can view the alarm messages that were sent just before the crash Conversely the contents of the log message buffer residing in system memory are lost when a crash occurs Use the modify alarmconf command to control the amount of flash memory allocated to the alarm message buffer and to specify the size of each alarm message file within the buffer Also use themodify alarmconf command to control the number of alarm messages each file contains Viewing and

17. IISP route Because of the default IISP route s lack of a definite ATM address be careful when using these routes Observe the following rules when using default IISP routes e Never add more than one default IISP route on any SmartCell 6A000 Do not use default IISP routes as an easy way to create a route between two devices Do not over use default IISP routes Doing so can create overly complicated network topologies e When using IISP routes be careful not to create ambiguous routes or routing loops e Restrict the use of default IISP routes to gateway connections out of the local LAN segment IISP Routes and Network Topology IISP is implemented on the SmartCell 6A000 switch so that a route s destination address is some sequential portion always starting with the first byte of a 20 byte ATM address Usually the default netprefix is used first thirteen bytes However routes can be defined using more or fewer bytes than the thirteen netprefix bytes This ability to define destination addresses by masking off portions of an ATM address allows multiple SmartCell 6A000 switches to be connected in flexible configurations Furthermore you can change the netprefix of a switch or a port on a switch to any value by using the set netprefix command Combining these two capabilities you can define routes with simple addressing schemes and create hierarchical network topologies For example Figure 4 2 shows three groups of switches
