M4300-x Switch to Switch LACP LAG

Hi,

Thank you for using NETGEAR M4300 great series of switches. 

You will find the CLI commands for LAGs and LACP in the  CLI Manual starting page 491. You can find all the technical documentation in M4300 support pages, for instance here.

The CLI command is called port-channel, like at Cisco. There are 128 LAGs that are provisioned already in your M4300 switch: lag 1; lag 2; lag 3 etc. LACP is enabled by default, a command is needed to "remove" LACP and consider the LAG static instead. The LAGs can be called by their LAG name (lag 1; lag 2; lag 3; etc.) or by their slot/interface number: the <<lag 1>> unit/slot/interface number is 0/13/1, for instance. The unit is "0" because this is a virtual interface and the slot number is 13 for LAGs. Let's say you want to add Port-1 and Port-2 to <<lag 1>>, it means you want to add physical interfaces 1/0/1 and 1/0/2 from your Unit-1 switch to the virtual interface 0/13/1. Let's say you want to name this <<lag 1>> as TestLAG in your switch. Follow the logic:

(M4300-12X12F) >en

(M4300-12X12F) #config

(M4300-12X12F) (Config)#port-channel ?

adminmode Enable/Disable the port-channel's administrative Mode.
linktrap Enable/Disable Link Up/Down traps for this port.
load-balance Configures port-channel load balance.
name Configure a name for the interface port-channel.
system Configure port channel system priority (LAG).

(M4300-12X12F) (Config)#port-channel name lag 1 TestLAG

-or -:

 (M4300-12X12F) (Config)#port-channel name 0/13/1 TestLAG

(M4300-12X12F) (Config)#port-channel load-balance ?

1 Src MAC, VLAN, EType, incoming port
2 Dest MAC, VLAN, EType, incoming port
3 Src/Dest MAC, VLAN, EType, incoming port
4 Src IP and Src TCP/UDP Port fields
5 Dest IP and Dest TCP/UDP Port fields
6 Src/Dest IP and TCP/UDP Port fields
7 Enhanced hashing mode

- the default is 3 Src/Dest MAC, VLAN, Ethertype and incoming port - you should select the mode based on your peering device (the same mode should be selected on both ends). For instance:

(M4300-12X12F) (Config)#port-channel load-balance 6 0/13/1

(M4300-12X12F) (Config)#interface 1/0/1-1/0/2

(M4300-12X12F) (Interface 1/0/1-1/0/2)#addport lag 1

1/0/1 interface is part of a port-channel.
1/0/2 interface is part of a port-channel.

(M4300-12X12F) (Interface 1/0/1-1/0/2)#exit

-or -:

(M4300-12X12F) (Interface 1/0/1-1/0/2)#addport 0/13/1

1/0/1 interface is part of a port-channel.
1/0/2 interface is part of a port-channel.
(M4300-12X12F) (Interface 1/0/1-1/0/2)#exit

(M4300-12X12F) (Config)#exit

(M4300-12X12F) #show port-channel ?

<lag-intf-num> Enter LAG interface number.
<unit/slot/port> Enter permissible interface in unit/slot/port format.
all Enter 'all' for all interfaces.
brief Display port-channel static capability and summary
information for the device.
system Display port-channel system priority.

(M4300-12X12F) #show port-channel all
