You have enabled configuration synchronization between two Cisco Nexus 5548UP Switches. You create a
port channel on switch 1 and determine that it was not
synchronized with its peer. The peer switch can be pinged on the management VRF. When
you check your peer status, you receive a “peer notreachable” message in the command
output. What is the explanation for this?
A.
CDP is disabled.
B.
An LACP mismatch exists on the peer interfaces.
C.
UDLD is disabled
D.
CFSoIP is disabled.
E.
Multicast routing is enabled.
Benefits of Configuration Synchronization
Configuration synchronization benefits are as follows:
•Provides a mechanism to synchronize configuration from one switch to another switch.
•Merges configurations when connectivity is established between peers.
•Allows you to choose which configuration is synchronized.
•Provides mutual exclusion for commands.
•Provides verify and commit Cisco NX-OS commands.
•Supports existing session and port profile functionality.
•Provides an import command to migrate existing vPC configurations to a switch profile.
•Supports Gigabit Expansion Module (GEM) and Fabric Extender (FEX) pre-provisioning.
Requirements
The requirements for configuration synchronization are as follows:
•Cisco NX-OS Release 5.0(2)N1(1) or a later release.
•Cisco Fabric Services over IP (CFSoIP) enabled on each peer, including an identical CFSoIP multicast address.
•Identical switch profiles on each switch.
•Configured peer IP addresses.
