。
Trunking: Configures multiple network ports in parallel to increase the link speed
beyond the limits of any single port.
。
LACP: It is part of IEEE specification 802.3ad that allows several physical ports to be
bundled together to form a single logical channel. This increases the bandwidth and
provides automatically failover when link status fails on a port.
。
Balance-alb: Adaptive load balancing includes balance-tlb plus receives load balancing
(rlb) for IPV4 traffic, and does not require any special switch support. The receive load
balancing is achieved by ARP negotiation. The bonding driver intercepts the ARP
Replies sent by the local system on their way out and overwrites the source hardware
address with the unique hardware address of one of the slaves in the bond such that
different peers use different hardware addresses for the server.
Set VLAN ID: VLAN is a logical grouping mechanism implemented on switch device. VLANs
are collections of switching ports that comprise a single broadcast domain. It allows network
traffic to flow more efficiently within these logical subgroups. Please consult your network
switch user manual for VLAN setting instructions. Most of the work is done at the switch part.
All you need to do is to make sure that your iSCSI port's VLAN ID matches that of switch port.
If your network environment supports VLAN, you can click Set VLAN ID to change the
configurations. Fill in VLAN ID and Priority settings to enable VLAN.
。
VLAN ID: VLAN ID is a 12-bit number. Its range is from 2 to 4094, while 0, 1, and 4095
are reserved for special purposes.
。
Priority: The PCP (Priority Code Point) is a 3-bit number and reserved for QoS. The
definition complies with IEEE 802.1p protocol, ranging from 0 to 7, with 0 as the
default value. In normal cases, you don't need to set this value. Using the default will
do just fine.
TIP: If network ports are assigned with VLAN ID before creating aggregation
takes place, aggregation will remove VLAN ID. You need to repeat the steps to
set VLAN ID for the aggregation group.
