DELL N3000 User Manual

Configuring Link Aggregation

The administrator should also ensure that the following are identical 

before enabling MLAG:
–

FDB  entry  aging  timers

–

Static MAC entries.

–

ACL configuration

4 Interface Configuration

–

PFC configuration

–

CoS queue assignments

5 VLAN configuration

–

MLAG VLANs must span the MLAG topology and be configured on 

both MLAG peers. This means that every MLAG VLAN must connect 

to two partner LAGs.

–

VLAN termination of an MLAG VLAN on an MLAG peer is not 

supported.

6 Switch firmware versions

Except during firmware upgrade, the peer switch firmware versions must 

be identical, as subtle differences between versions may cause instability.

The administrator must ensure that the above configuration items are 

configured identically on the MLAG interfaces on both of the MLAG peers 

before enabling the MLAG feature. If the configuration settings are not in 

sync, the MLAG behavior is undefined. Once the above configuration is in 

place and consistent, the two switches will form an MLAG that operates in 

the desired manner. The MLAG may form even if the configuration is not 

consistent, however, it may not operate consistently in all situations.
