Scheduling a System Reset Chapter 27 Administering the Switch The switch forwards IP traffic that is generated by the switch using the longest address match in the IP routing table. The switch does not use the IP routing table to forward traffic from connected devices. The IP routing table is used by the switch only to forward IP traffic that is generated by the switch itself (for example, Telnet, TFTP, and ping). In software releases prior to software release 5.1, the classful subnet mask is always used (you cannot specify the subnet mask for the destination network). To configure a static route, perform this task in privileged mode: Step 1 Step 2 Task Command Configure a static route to the remote network. set ip route destination[/netmask] gateway [metric] Verify that the static route appears correctly in the show ip route IP routing table. This example shows how to configure a static route on the switch and how to verify that the route is configured properly in the routing table: Console> (enable) set ip route 172.16.16.0/20 172.20.52.127 Route added.

This feature allows you to upgrade software during business hours and schedule the system upgrade after business hours to avoid a major impact on users. You can also use the schedule reset feature when trying out new features on a switch. To avoid misconfiguration or the possibility of losing network connectivity to the device, you can set up the startup configuration feature and schedule a reset to occur in 30 minutes. You can then change the configuration, and if connectivity is lost, the system will reset in 30 minutes and return to the previous configuration. Scheduling a Reset at a Specific Time You can specify an absolute time and date at which the reset will take place, using the reset at command. The month and day argument is optional. If you do not specify a month and day, the reset will take place on the current day if the time that is specified is later than the current time. If the time that is scheduled for reset is earlier than the current time, the reset will take place on the following day. 27-10 Catalyst 4500 Series, Catalyst 2948G, Catalyst 2980G Switches Software Configuration Guide-Release 8.1 78-15486-01
