Upgrading Your ACE Software in a Redundant Configuration Step 4 Copy the new software image to the image directory of each ACE (active and standby) by entering the copy ftp, copy sftp, or the copy tftp command in Exec mode. For example, to copy the image with the name c4710ace-t1k9-mz.A5_1_0.bin through FTP, enter: ACE-1/Admin# copy ftp://server1/images//c4710ace-t1k9-mz.A5_1_0.bin image: Enter source filename[/images/c4710ace-t1k9-mz.A5_1_0.bin]? Enter the destination filename[]? [c4710ace-t1k9-mz.A5_1_0.bin] File already exists, do you want to overwrite?[y/n]: [y] Enter hostname for the ftp server[server1]? Enter username[]? user1 Enter the file transfer mode[bin/ascii]: [bin] Enable Passive mode[Yes/No]: [Yes] no Password: Step 5 Ensure that the new software image is present on both the active and standby ACEs by entering the dir command in Exec mode. For example, enter: ACE-1/Admin# dir image:c4710ace-t1k9-mz.A4_2_0.bin 35913728 Oct 25 2010 01:17:01 c4710ace-t1k9-mz.A5_1_0.bin Usage for image: filesystem 828182528 bytes total used 54165504 bytes free 882348032 bytes total Step 6 Verify the current BOOT environment variable and configuration register setting by entering the show bootvar command in Exec mode. For example, enter: ACE-1/Admin# show bootvar BOOT variable = "image:c4710ace-t1k9-mz.A5_1_0.bin" Configuration register is 0x1 Step 7 Remove the existing image from the boot variable on ACE-1 by entering the no boot system image:ACE_image command in configuration mode. For example, to remove the A3(2.1) image, enter: ACE-1/Admin# configure Enter configuration commands, one per line. End with CNTL/Z. ACE-1/Admin(config)# no boot system image:c4710ace-t1k9-mz.A3_2_1.bin Step 8 Configure ACE-1 to autoboot from the latest ACE appliance image. To set the boot variable and configuration register to 0x1 (perform auto boot and use startup-config file), use the boot system image: and config-register commands in configuration mode. For example, enter: ACE-1/Admin(config)# boot system image:c4710ace-t1k9-mz.A5_1_0.bin ACE-1/Admin(config)# config-register 0x1 ACE-1/Admin(config)# exit ACE-1/Admin# show bootvar BOOT variable = "image:c4710ace-t1k9-mz.A5_1_0.bin" Configuration register is 0x1 Step 9 Step 10 On the standby ACE ACE (ACE-2), perform the following: • Enter the show running-config command and ensure that all the changes made in the active ACE (ACE-1) are also reflected on the standby ACE. • Enter the show bootvar command to verify that the boot variable was synchronized with ACE-1. Verify the state of each ACE by entering the show ft group detail command in Exec mode. Upgrade the ACE that has its Admin context in the STANDBY_HOT state (ACE-2) first by entering the reload command in Exec mode. ACE-2/Admin# reload This command will reboot the system Save configurations for all the contexts. Save?
