Software Upgrades and Downgrades With Switch Profiles
Merge Checks
Merge checks are done on the peer switch that is receiving a configuration. The merge checks ensure that the
received configuration does not conflict with the switch profile configuration that already exists on the receiving
switch. The merge check occurs during the merge or commit process. Errors are reported as merge failures
and must be manually corrected.
When one or both switches are reloaded and the configurations are synchronized for the first time, the merge
check verifies that the switch profile configurations are identical on both switches. Differences in the switch
profiles are reported as merge errors and must be manually corrected.
Software Upgrades and Downgrades With Switch Profiles
When you downgrade to an earlier release, you are prompted to remove an existing switch profile that is not
supported on earlier releases.
When you upgrade from an earlier release, you have the option to move some of the running-configuration
commands to a switch profile. The import command allows you to import relevant switch profile commands.
An upgrade can occur if there are buffered configurations (uncommitted); however, the uncommitted
configurations are lost.
When you perform an In Service Software Upgrade (ISSU) on one of the switches included in a switch profile,
a configuration synchronization cannot occur because the peer is unreachable.
Prerequisites for Switch Profiles
Switch profiles have the following prerequisites:
• You must enable Cisco Fabric Series over IP (CFSoIP) distribution over mgmt0 on both switches by
• You must configure a switch profile with the same name on both peer switches by entering the config
• Configure each switch as peer switch by entering the sync-peers destination command
Guidelines and Limitations for Switch Profiles
Consider the following guidelines and limitations when configuring switch profiles:
• You can only enable configuration synchronization using the mgmt0 interface.
• Configuration synchronization is performed using the mgmt 0 interface and cannot be performed using
• You must configure synchronized peers with the same switch profile name.
• Commands that are qualified for a switch profile configuration are allowed to be configured in the
• Supported switch profile commands relate to vPC commands. FCoE commands are not supported.
• One switch profile session can be in progress at a time. Attempts to start another session will fail.
