For the member ports in an aggregation group, their basic configuration must be the same. The
basic configuration includes UVR,"SqU, IXTR, XNCP, rqtv"cvvtkdwvgu, OCE"Cfftguu"Ngctpkpi"
oqfg and other associated settings. The further explains are following:
If the ports, which are enabled for the IXTR, :2403S"XNCP, Xqkeg"XNCP, UVR, SqU,"Rqtv"

Kuqncvkqp," FJER"Upqqrkpi and Rqtv"Eqphkiwtcvkqp (Urggf"cpf"Hnqy"Eqpvtqn), are in a
LAG, their configurations should be the same.
The ports, which are enabled for the Rqtv" Ugewtkv{, Rqtv" Okttqt, OCE" Cfftguu" Hknvgtkpi,

Uvcvke"OCE"Cfftguu"Dkpfkpi,"Jcnh/Fwrngz"and":2403Z"Cwvjgpvkecvkqp, cannot be added to
the LAG.
It's not suggested to add the ports with CTR" Kpurgevkqp and FqU" Fghgpf enabled to the

LAG.
If the LAG is needed, you are suggested to configure the LAG function here before configuring the
other functions for the member ports.

1. Calculate the bandwidth for a LAG: If a LAG consists of the four ports in the speed of
1000Mbps Full Duplex, the theoretical maximum bandwidth of the LAG is up to 8000Mbps
(2000Mbps * 4) because the bandwidth of each member port is 2000Mbps counting the
up-linked speed of 1000Mbps and the down-linked speed of 1000Mbps.
2. The traffic load of the LAG will be balanced among the ports according to the Aggregate
Arithmetic. If the connections of one or several ports are broken, the traffic of these ports will
be transmitted on the normal ports, so as to guarantee the connection reliability.
Depending on different aggregation modes, aggregation groups fall into two types: Uvcvke" NCI
and NCER"Eqphki. The LAG function is implemented on the"NCI"Vcdng, Uvcvke"NCI and NCER"
Eqphki"configuration"pages.
