Multi-homed / Trunking / LACP:
The following is the description of multi-homed/trunking/LACP.
1.
Multi-homed
: Default mode. Each of iSCSI data port is connected by itself and is
not set to link aggregation and trunking. Selecting this mode can also remove the
setting of Trunking/LACP at the same time.
2.
Trunking
: defines the use of multiple iSCSI data ports in parallel to increase the
link speed beyond the limits of any single port.
3.
LACP
: The Link Aggregation Control Protocol (LACP) is part of IEEE specification
802.3ad that allows bundling several physical ports together to form a single logical
channel. LACP allows a network switch to negotiate an automatic bundle by sending
LACP packets to the peer. The advantages of LACP are: (1) increase in bandwidth,
and (2) failover when link status fails on a port.
Trunking/LACP setting can be changed by clicking the button “
”.
There are 4 iSCSI data ports. Select at least two NICs for link aggregation.
For example, LAN1 and LAN2 are set to Trunking mode. LAN3 and LAN4 are set to
LACP mode. To remove Trunking/LACP setting, mouse move to the gray button of LAN
port, click
“Delete link aggregation”
. Then it will pop up a message to confirm.
