Performing SRP Checks
Service Redundancy Protocol (SRP) checks verify that the mechanism for monitoring ICSR system status is operational.
Step 1
Run show srp monitor all.
Step 2
Review the output for any issues that may preclude performing the software update.
Performing BGP Checks
Border Gateway Protocol (BGP) checks are only required when BGP is used to support redundant interchassis
communication. These checks are run per context and per service type.
communication. These checks are run per context and per service type.
Step 1
For each BGP-enabled context, run show ip bgp summary. Verify that the BGP peers are connected and IPv4 and IPv6
peers are up. Repeat for all BGP-enable contexts.

Step 2

Updating the Boot Record
You must add a new boot stack entry for the recently downloaded software image (.bin) file.
Step 1
Run the Exec mode show boot command to verify that there are less than 10 entries in the boot.sys file and that a higher
priority entry is available (minimally there is no priority 1 entry in the boot stack).
priority entry is available (minimally there is no priority 1 entry in the boot stack).
Step 2
Create a new boot stack entry for the new file group, consisting of the new operating system image file and the currently
used CLI configuration file by entering the following Global Configuration command:
used CLI configuration file by entering the following Global Configuration command:
[local]<host_name>(config)# boot system priority number image image_url
/flash/filename config cfg_url /flash/filename
/flash/filename config cfg_url /flash/filename
Step 3
Assign the next highest priority to this entry, by using the <N-1> method, wherein you assign a priority number that is
one number less than your current highest priority.
one number less than your current highest priority.
If priority 1 is in use, you must renumber the existing entries to ensure that at least that priority is available.
The maximum number of boot stack entries that can be contained in the boot.sys file is 10. If there are already 10 entries
in the boot stack, you must delete at least one of these entries (typically, the lowest priority) and, if necessary, renumber
some or all of the other entries before proceeding. Use the no boot system priority command to delete a book stack
entry.

Synchronizing File Systems
Synchronize the local file systems by entering the following Exec mode command:
[local]<host_name># filesystem synchronize all
