2 reload reload To reload the VM with location and card level details, use the reload command in the appropriate mode. reload Syntax Description This command has no keywords or arguments. Command Default No default behavior or values Command Modes EXEC Command History Releases Release Modifications This command was introduced. Usage Guidelines To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance. When the reload command is used and a switchover occurs, the running (active) software configuration is automatically maintained during switchover. Caution If a standby is not installed or is not in the ready state, then the router experiences a loss of service while the active is reloading Cisco IOS XR software. To view the status of the standby, issue the show redundancy command in EXEC mode. If you use the reload command and there is no available standby node, you are prompted to continue with the reload: RP/0/RP0/CPU0:router# reload Standby card not present or not Ready for failover. Proceed?[confirm]y root-lr Operations execute 2 OL

3 reload Examples The following example shows how to reload the active. If a standby is in the ready state, then the router fails over to the standby. If the standby is not installed or is not in the ready state, then the router enters ROMMON mode and routing operations stop. Related Commands Command reload (administration EXEC) show redundancy Description Reloads a node or all nodes on a single chassis or multishelf system. Displays the status of route processor redundancy. OL

4 reload (administration EXEC) reload (administration EXEC) To reload a node or all nodes on a single chassis or multishelf system, use the reload command in the appropriate mode. reload [location {node-id all} rack rack-number] Syntax Description location {node-id all} rack-number (Optional) Specifies the node to reload. The node-id argument is entered in the rack/slot notation. The all keyword specifies all RP nodes. Rack number of the line card chassis or fabric chassis. Command Default None Command Modes System Admin EXEC Command History Release Release Modification This command was introduced. Usage Guidelines To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance. To reload a specific node on the router, specify the reload command with the location node-id keyword and argument. The node-id is expressed in the rack/slot notation. root-system Operations execute Examples The following example shows how to reload all nodes on the router: sysadmin:vm_0 # reload location all Note To ensure the sanity of the configuration file system, enter the cfs check command. 4 OL

7 show epm trace boot Usage Guidelines To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance. The show epm trace boot command provides a simple way of tracking and time-stamping critical events to clearly understand their temporal relationship to one another and the amount of time spent performing critical operations. basic services Operations read Examples The following example shows sample output from the show epm trace boot command: RP/0/RP0/CPU0:router#sh epm trace boot Tue Nov 12 11:16: UTC 14 wrapping entries (1088 possible, 64 allocated, 0 filtered, 14 total) Nov 7 06:22: epm/boot 0/RP0/CPU0 00:00:11 - [processmgr] process-start Nov 7 06:22: epm/boot 0/RP0/CPU0 00:00:12 - [processmgr] start-level: admin Nov 7 06:22: epm/boot 0/RP0/CPU0 00:00:51 - [devc-conaux-con] exec-available Nov 7 06:22: epm/boot 0/RP0/CPU0 00:00:53 - [processmgr] admin-plane-up Nov 7 06:22: epm/boot 0/RP0/CPU0 00:00:53 - [processmgr] start-level: infra Nov 7 06:23: epm/boot 0/RP0/CPU0 00:01:10 - [processmgr] start-level: active Nov 7 06:23: epm/boot 0/RP0/CPU0 00:01:28 - [placed] pi-plane-up Nov 7 06:23: epm/boot 0/RP0/CPU0 00:01:28 - [placed] pi-plane-up Nov 7 06:23: epm/boot 0/RP0/CPU0 00:01:31 - [processmgr] start-level: final Nov 7 06:23: epm/boot 0/RP0/CPU0 00:01:48 - [placed] lr-plane-up Nov 7 06:23: epm/boot 0/RP0/CPU0 00:01:52 - [cfgmgr-rp] lr-config-start Nov 7 06:24: epm/boot 0/RP0/CPU0 00:02:50 - [cfgmgr-rp] lr-config-done Nov 7 06:24: epm/boot 0/RP0/CPU0 00:02:50 - [cfgmgr-rp] bulk-interface-config-start Nov 7 06:24: epm/boot 0/RP0/CPU0 00:02:50 - [cfgmgr-rp] node-config-done In this sample output, the time stamp following sign is the elapsed time in the format hh:mm:ss since the execution phase started (for example, since node start, in the case of a boot).
