Netgear M5300-28G-POE+ (GSM7228PSv1h2) - 12-Port Managed Gigabit Switch Ratgeber Für Administratoren

In this configuration example, each MLAG switch has three LAGs:

Two LAGs to the remote LAG partner: LAG2 and LAG3

One LAG to the peer MLAG device: LAG1

If more remote devices are needed, follow the steps in the following sections to add them.

This configuration example is presented as CLI commands and as a web interface 
procedure.

Enable MLAG globally.

(Switch P or S) #config

(Switch P or S) (Config)#feature vpc

Enable the MLAG keep-alive protocol in the MLAG (VPC) domain. 

This step is mandatory.

(Switch P or S) (Config)#vpc domain 1

(Switch P or S) (Config-VPC 1)#peer-keepalive enable 

(Switch P or S) (Config-VPC 1)#exit

Enable the MLAG peer link on LAG1 that is used to connect the MLAG peers.

After you have configured a peer link, the traffic from the peer link is prevented from 

leaving any MLAG member port. When a failure occurs on one MLAG peer switch and 
the traffic has to flow through the MLAG member ports of the peer, the traffic that arrives 
from the peer link on the second MLAG device can leave only from select MLAG 
interfaces. Therefore, you need to configure the following options on the port channel of 
the peer link:

Disable STP on the peer link.

Include the peer link in all the VLANs that are configured on all MLAG interfaces on 
the device.

Enable egress tagging on the peer link.

NETGEAR recommends that you use dynamic LAGs as port channels.

NETGEAR recommends that you configure Unidirectional Link Detection (UDLD) to 
detect and shut down any unidirectional links.
