Upgrading Software on a PRE4
Step 3
Copy the running configuration to the startup configuration.
Router#
copy running-config startup-config
Step 4
Reload the software by entering the
reload
command.
Router#
reload
The system is now using the new Cisco IOS image.
Upgrading Software on Redundant PRE4
To upgrade software on two redundant PRE4, follow these steps:
Step 1
Verify that both the PRE4 are up using the
show redundancy states
command.
Router#
show redundancy states
my state = 13 -ACTIVE
peer state = 8 -STANDBY HOT
Mode = Duplex
Unit = Primary
Unit ID = 0
Redundancy Mode (Operational) = SSO
Redundancy Mode (Configured) = SSO
Redundancy State = SSO
Maintenance Mode = Disabled
Manual swact enabled
Communications = Up
client count = 38
client_notification_TMR = 30000 milliseconds
RF debug mask = 0x0
Step 2
Copy the Cisco IOS image from a TFTP server to Disk0 on the active PRE4.
Router#
copy tftp disk0:
Address or name of remote host []? 223.255.254.248
Source filename []? c10008/c10k4-p11-mz
Destination filename [c10k4-p11-mz]?
Accessing tftp://223.255.254.248/c10008/c10k4-p11-mz...
Loading c10008/c10k4-p11-mz from 223.255.254.248(via FastEthernet0/0/0):
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!...
[OK - 25750196 bytes]
25750196 bytes copied in 50.64 secs (508495 bytes/sec)
Step 3
Copy the Cisco IOS image from a TFTP server to Disk0 on the standby PRE4.
Router#
copy tftp stby-disk0
The output is similar to that shown in the previous step.
