Planning for setting up an M-LAG system
Determining device installation locations
An M-LAG system can be set up with only two devices. Reserve sufficient space in the tank for
installation of the devices.
Reserving physical ports for M-LAG connection
To set up an M-LAG system, you must establish a peer link and a keepalive link between the two
devices.
The M-LAG member devices exchange protocol packets and transmit data traffic over the peer link.
An M-LAG system has only one peer link. You can create a peer-link interface on each M-LAG
member device, and the link between the two peer-link interfaces is the peer link.
The M-LAG member devices exchange keepalive packets over the keepalive link to detect
multi-active collisions when the peer link is down.
Peer link
In addition to protocol packets, the peer link also transmits data packets between the M-LAG
member devices when an uplink fails. When you set up the peer link, follow these restrictions and
guidelines:
•
Assign at least two physical interfaces to the aggregation group for the peer-link interface.
•
The member ports in the aggregation group for the peer-link interface must have the same
speed.
•
If an M-LAG system is attached to a large number of servers by using non-M-LAG interfaces,
take the size of the traffic sent among those servers into account when you determine the
bandwidth of the peer link.
Description
Plan for setting up the M-LAG system based on the network and
device conditions:
•
Determine the installation locations of the switches.
•
Reserve physical ports for M-LAG connections.
•
Plan the cable connection scheme.
