Information About Switch Profiles
Several applications require consistent configuration across Cisco Nexus Series switches in the network. For example, with a Virtual Port Channel (vPC), you must have identical configurations. Mismatched configurations can cause errors or misconfigurations that can result in service disruptions.
The configuration synchronization (config-sync) feature allows you to configure one switch profile and have the configuration be automatically synchronized to the peer switch. A switch profile provides the following benefits:
-
Allows configurations to be synchronized between switches.
-
Merges configurations when connectivity is established between two switches.
-
Provides control of exactly which configuration gets synchronized.
-
Ensures configuration consistency across peers through merge and mutual-exclusion checks.
-
Provides verify and commit semantics.
-
Supports configuring and synchronizing port profile configurations.
-
Provides an import command to migrate existing vPC configurations to a switch profile.
Switch Profile Configuration Modes
The switch profile feature includes the following configuration modes:
Configuration Synchronization Mode
The configuration synchronization mode (config-sync) allows you to create switch profiles using the config sync command on the local switch that you want to use as the master. After you create the profile, you can enter the config sync command on the peer switch that you want to synchronize.
Switch Profile Mode
The switch profile mode allows you to add supported configuration commands to a switch profile that is later synchronized with a peer switch. Commands that you enter in the switch profile mode are buffered until you enter the commit command.
Switch Profile Import Mode
When you upgrade from an earlier release, you have the option to enter the import command to copy supported running-configuration commands to a switch profile. After entering the import command, the switch profile mode (config-sync-sp) changes to the switch profile import mode (config-sync-sp-import). The switch profile import mode allows you to import existing switch configurations from the running configuration and specify which commands you want to include in the switch profile.
Because different topologies require different commands that are included in a switch profile, the import command mode allows you to modify the imported set of commands to suit a specific topology. For example, a dual homed Fabric Extender (FEX) topology requires that most of the configuration is synchronized. In other vPC topologies, the configuration that needs to be synchronized might be a much smaller set of commands.
You need to enter the commit command to complete the import process and move the configuration into the switch profile. Because configuration changes are not supported during the import process, if you added new commands before entering the commit command, the switch profile remains unsaved and the switch remains in the switch profile import mode. You can remove the added commands or abort the import. Unsaved configurations are lost if the process is aborted. You can add new commands to the switch profile after the import is complete.
Configuration Validation
Two types of configuration validation checks can identify two types of switch profile failures:
Mutual Exclusion Checks
To reduce the possibility of overriding configuration settings that are included in a switch profile, mutual exclusion (mutex) checks the switch profile commands against the commands that exist on the local switch and the commands on the peer switch. A command that is included in a switch profile cannot be configured outside of the switch profile or on a peer switch. This requirement reduces the possibility that an existing command is unintentionally overwritten.
As a part of the commit process, the mutex-check occurs on both switches if the peer switch is reachable; otherwise, the mutex-check is performed locally. Configuration changes made from the configuration terminal occur only on the local switch.
If a mutex-check identifies errors, they are reported as mutex failures and they must be manually corrected.
The following exceptions apply to the mutual exclusion policy:
Interface configuration—Port channel interfaces must be configured fully in either switch profile mode or global configuration mode.
NoteSeveral port channel subcommands are not configurable in switch profile mode. These commands can be configured from global configuration mode even if the port channel is created and configured in switch profile mode.
For example, the following command can only be configured in global configuration mode:
switchport private-vlan association trunk primary-vlan secondary-vlan
Shutdown/no shutdown
System QoS
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 entering the cfs ipv4 distribute command.
You must configure a switch profile with the same name on both peer switches by entering the config sync and switch-profile commands.
Configure each switch as peer switch by entering the sync-peers destination command
Guidelines and Limitations for Switch Profiles
The Switch profile has the following guidelines and limitations:
You can only enable configuration synchronization using the mgmt0 interface.
Configuration synchronization is performed using the mgmt 0 interface and cannot be performed using a management SVI.
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 configuration switch profile (config-sync-sp) mode.
Supported switch profile commands relate to virtual port channel (vPC) commands. Fiber Channel over Ethernet (FCoE) commands are not supported.
One switch profile session can be in progress at a time. Attempts to start another session will fail.
Supported command changes made from the configuration terminal mode are blocked when a switch profile session is in progress. You should not make unsupported command changes from the configuration terminal mode when a switch profile session is in progress.
When you enter the commit command and a peer switch is reachable, the configuration is applied to both peer switches or neither switch. If there is a commit failure, the commands remain in the switch profile buffer. You can then make necessary corrections and try the commit again.
We recommend that you enable preprovisioning for all Generic Expansion Modules (GEMs) and Cisco Nexus Fabric Extender modules whose interface configurations are synchronized using the configuration synchronization feature. Follow these guidelines in Cisco Nexus Fabric Extender active/active topologies where the Fabric Extenders might not be online on one switch and its configuration is changed and synchronized on the other switch. In this scenario, if you do not enable preprovisioning, a commit fails and the configuration is rolled back on both switches.
Once a port channel is configured using switch profile mode, it cannot be configured using global configuration (config terminal) mode.
NoteSeveral port channel subcommands are not configurable in switch profile mode. These commands can be configured from global configuration mode even if the port channel is created and configured in switch profile mode.
For example, the following command can only be configured in global configuration mode:
switchport private-vlan association trunk primary-vlan secondary-vlan
Shutdown and no shutdown can be configured in either global configuration mode or switch profile mode.
If a port channel is created in global configuration mode, channel groups including member interfaces must also be created using global configuration mode.
Port channels that are configured within switch profile mode may have members both inside and outside of a switch profile.
If you want to import a member interface to a switch profile, the port channel including the member interface must also be present within the switch profile.
Guidelines for Synchronizing After Reboot, Connectivity Loss, or Failure
Synchronizing configurations after vPC peer link failure— If both switches are operational when a peer link fails, the secondary switch shuts down its vPC ports. In a Fabric Extender A/A topology, the A/A Fabric Extender disconnects from the secondary switch. If the configuration is changed using a switch profile on the primary switch, configurations are not accepted on the secondary switch unless the A/A Fabric Extender is preprovisioned. When using the configuration synchronization feature, we recommend that you preprovision all A/A Fabric Extenders.
Synchronizing configurations after mgmt0 interface connectivity loss—When mgmt0 interface connectivity is lost and configuration changes are required, apply the configuration changes on both switches using the switch profile. When connectivity to the mgmt0 interface is restored, both switches synchronize automatically.
If a configuration change is made on only one switch, a merge occurs when the mgmt0 interface comes up and the configuration is applied on the other switch.
Synchronizing configurations when an ISSU is performed on one switch and a configuration change is made on the peer switch—In a vPC topology, configuration changes on the peer switch are not allowed when an ISSU is performed on the other switch. In topologies without vPCs, configuration changes are allowed and the switch undergoing an ISSU synchronizes new configurations when the upgrade is complete.
Configuring Switch Profiles
You can create and configure a switch profile. Enter the switch-profile name command in the configuration synchronization mode (config-sync).
You must create the switch profile with the same name on each switch and the switches must configure each other as a peer. When connectivity is established between switches with the same active switch profile, the switch profiles are synchronized.
The following example shows how to configure a switch profile and shows the switch profile status.
switch# configuration terminal switch(config)# cfs ipv4 distribute switch(config-sync)# switch-profile abc switch(config-sync-sp)# sync-peers destination 10.1.1.1 switch(config-sync-sp)# show switch-profile abc status Start-time: 15801 usecs after Mon Aug 23 06:21:08 2010 End-time: 6480 usecs after Mon Aug 23 06:21:13 2010 Profile-Revision: 1 Session-type: Initial-Exchange Peer-triggered: Yes Profile-status: Sync Success Local information: ---------------- Status: Commit Success Error(s): Peer information: ---------------- IP-address: 10.1.1.1 Sync-status: In Sync. Status: Commit Success Error(s): switch(config-sync-sp)# exit switch#
Adding a Switch to a Switch Profile
Enter the sync-peers destination destination IP command in switch profile configuration mode to add the switch to a switch profile.
Follow these guidelines when adding switches:
Switches are identified by their IP address.
Destination IPs are the IP addresses of the switches that you want to synchronize.
The committed switch profile is synchronized with the newly added peers (when they are online) if the peer switch is also configured with configuration synchronization.
If you want to import a member interface to a switch profile, the port channel including the member interface must also be present within the switch profile.
After creating a switch profile on the local switch, you must add the second switch that will be included in the synchronization.
Adding or Modifying Switch Profile Commands
To modify a command in a switch profile, add the modified command to the switch profile and enter the commit command to apply the command and synchronize the switch profile to the peer switch if it is reachable.
Follow these guidelines when adding or modifying switch profile commands:
Commands that are added or modified are buffered until you enter the commit command.
Commands are executed in the same order in which they are buffered. If there is an order-dependency for certain commands, for example, a QoS policy must be defined before being applied, you must maintain that order; otherwise, the commit might fail. You can use utility commands, such as the show switch-profile name buffer command, the buffer-delete command, or the buffer-move command, to change the buffer and correct the order of already entered commands.
After configuring a switch profile on the local and the peer switch, you must add and commit the supported commands to the switch profile. The commands are added to the switch profile buffer until you enter the commit command. The commit command does the following:
Triggers the mutex check and the merge check to verify the synchronization.
Creates a checkpoint with a rollback infrastructure.
Applies the configuration on the local switch and the peer switch.
Executes a rollback on all switches if there is a failure with an application on any of the switches in the switch profile.
Deletes the checkpoint.
The following example shows how to create a switch profile, configure a peer switch, and add commands to the switch profile.
switch# configuration terminal switch(config)# cfs ipv4 distribute switch(config-sync)# switch-profile abc switch(config-sync-sp)# sync-peers destination 10.1.1.1 switch(config-sync-sp)# interface port-channel100 switch(config-sync-sp-if)# speed 1000 switch(config-sync-sp-if)# interface Ethernet1/1 switch(config-sync-sp-if)# speed 1000 switch(config-sync-sp-if)# channel-group 100 switch(config-sync-sp)# verify switch(config-sync-sp)# commit switch(config-sync-sp)# exit switch#
The following example shows an existing configuration with a defined switch profile. The second example shows how the switch profile command changed by adding the modified command to the switch profile.
switch# show running-config
switch-profile abc
interface Ethernet1/1
switchport mode trunk
switchport trunk allowed vlan 1-10
switch# config sync
switch(config-sync)# switch-profile abc
switch(config-sync-sp)# interface Ethernet1/1
switch(config-sync-sp-if)# switchport trunk allowed vlan 5-10
switch(config-sync-sp-if)# commit
switch# show running-config
switch-profile abc
interface Ethernet1/1
switchport mode trunk
switchport trunk allowed vlan 5-10
Importing a Switch Profile
You can import a switch profile based on the set of commands that you want to import. Using the configuration terminal mode, you can do the following:
Add selected commands to the switch profile.
Add supported commands that were specified for an interface.
Add supported system-level commands.
Add supported system-level commands excluding the physical interface commands.
When you import commands to a switch profile, the switch profile buffer must be empty.
If new commands are added during the import, the switch profile remains unsaved and the switch remains in the switch profile import mode. You can enter the abort command to stop the import. For additional information importing a switch profile, see the “Switch Profile Import Mode” section.
The following example shows how to import supported system-level commands excluding the Ethernet interface commands into the switch profile named sp:
switch(config-vlan)# conf sync switch(config-sync)# switch-profile sp Switch-Profile started, Profile ID is 1 switch(config-sync-sp)# show switch-profile buffer switch-profile : sp ---------------------------------------------------------- Seq-no Command ---------------------------------------------------------- switch(config-sync-sp)# import running-config exclude interface ethernet switch(config-sync-sp-import)# switch(config-sync-sp-import)# show switch-profile buffer switch-profile : sp ---------------------------------------------------------- Seq-no Command ---------------------------------------------------------- 3 vlan 100-299 4 vlan 300 4.1 state suspend 5 vlan 301-345 6 interface port-channel100 6.1 spanning-tree port type network 7 interface port-channel105 switch(config-sync-sp-import)#
Importing Configurations in a vPC Topology
You can import configurations in a two-switch vPC topology.
Note | For specific information about the following steps, see the appropriate sections in this chapter. |
Configure the switch profile with the same name on both switches.
Import the configurations to both switches independently.
NoteEnsure that the configuration moved to the switch profile on both switches is identical; otherwise, a merge-check failure might occur.
Configure the switches by entering the sync-peer destination command.
Verify that the switch profiles are the same by entering the appropriate show commands.
Verifying Commands in a Switch Profile
You can verify the commands that are included in a switch profile by entering the verify command in switch profile mode.
Isolating a Peer Switch
You can isolate a peer switch in order to make changes to a switch profile. This process can be used when you want to block a configuration synchronization or when you want to debug configurations.
Isolating a peer switch requires that you remove the switch from the switch profile and then add the peer switch back to the switch profile.
To temporarily isolate a peer switch, follow these steps:
Deleting a Switch Profile
You can delete a switch profile by selecting the all-config or the local-config option:
all-config—Deletes the switch profile on both peer switches (when both are reachable). If you choose this option and one of the peers is unreachable, only the local switch profile is deleted. The all-config option completely deletes the switch profile on both peer switches.
local-config—Deletes the switch profile on the local switch only.
Deleting a Switch from a Switch Profile
You can delete a switch from a switch profile.
Displaying the Switch Profile Buffer
The following example shows how to display the switch profile buffer for a service profile called sp:
switch# configure sync Enter configuration commands, one per line. End with CNTL/Z. switch(config-sync)# switch-profile sp Switch-Profile started, Profile ID is 1 switch(config-sync-sp)# show switch-profile sp buffer ---------------------------------------------------------- Seq-no Command ---------------------------------------------------------- 1 vlan 101 1.1 ip igmp snooping querier 10.101.1.1 2 mac address-table static 0000.0000.0001 vlan 101 drop 3 interface Ethernet1/2 3.1 switchport mode trunk 3.2 switchport trunk allowed vlan 101 switch(config-sync-sp)# buffer-move 3 1 switch(config-sync-sp)# show switch-profile sp buffer ---------------------------------------------------------- Seq-no Command ---------------------------------------------------------- 1 interface Ethernet1/2 1.1 switchport mode trunk 1.2 switchport trunk allowed vlan 101 2 vlan 101 2.1 ip igmp snooping querier 10.101.1.1 3 mac address-table static 0000.0000.0001 vlan 101 drop switch(config-sync-sp)#
Synchronizing Configurations After a Switch Reboot
If a Cisco Nexus Series switch reboots while a new configuration is being committed on a peer switch using a switch profile, complete the following steps to synchronize the peer switches after reload:
