Recommended Configuration Parameters; Verifying Parameter Consistency - OmniSwitch os6900 Network Configuration Manual

Configuring Multi-chassis Link Aggregation

Recommended Configuration Parameters

Multi-chassis peers in the same domain must maintain identical configuration and operational parameters.
Ensure that the mandatory parameters are the same on both peers. Multi-chassis functionality is optimal
with unified management on participating chassis. Any mismatch or mis-configuration can adversely
affect network traffic behavior. There is no automatic check or facility to check for mis-configuration.
Ensure that the following recommended parameters are configured identical on both the chassis.
•
MAC Address Aging Timer
•
MCLAG member ports: port speed and duplex
•
Static MAC Entries
•
QoS Configuration
•
Port Security Configuration
•
IGMP Snooping Configuration
•
IP interface configuration
•
Routing Protocols Configuration
•
VRRP Configuration

Verifying Parameter Consistency

Parameter consistency is performed automatically at start time and relevant runtime when any configura-
tion changes are applied to either chassis. If there is any persistent mismatch of the mandatory parame-
ters, then the global operation state of the Multi-Chassis feature will be updated as operationally down.
Inconsistency between some of the non-mandatory MCLAG aggregate parameters prevents a particular
MCLAG or all MCLAG aggregates from becoming operational. The mandatory parameters for MCLAG
and the impact of their violation are: as follows:
