ISCOM2600G-HI (A) Series Configuration Guide
Links that connect the DHD are configured to the same Link Aggregation Group (LAG).
Interface selection and link aggregation are implemented through LACP. In this case, the two
PEs in the same LAG appear to be in one Inter-Chassis Group (ICG).
The whole system, according to the configured priority, selects a PE from the ICG to be the
active one by using LACP. The active PE will communicate with DHD. In one ICG, only one
PE can be active and the other standby.
When the number of Up links between the active PE and the DHD is smaller than the
configured number of LAG links, or all uplink interfaces on the PE becomes Down, the
system will perform fault switching, making the other PoA active and the local PE standby.
When faults at the local PoA are cleared, the system will perform fault recovery, re-electing
the local PoA as the active one.
11.1.2 Preparing for configurations
Scenario
To provide higher bandwidth and reliability for a link between two devices, configure link
aggregation.
Prerequisite
11.1.3 Configuring manual link aggregation
Configure manual link aggregation for the ISCOM2600G-HI series switch as below.

Configure physical parameters of interfaces and make them Up.
In the same LAG, member interfaces that share loads must be identically configured.
Otherwise, data cannot be forwarded properly. These configurations include QoS, QinQ,
VLAN, interface properties, and MAC address learning.
QoS: traffic policing, traffic shaping, congestion avoidance, rate limit, SP queue,
–
WRR queue scheduling, interface priority and interface trust mode
QinQ: QinQ enabling/disabling status on the interface, added outer VLAN tag,
–
policies for adding outer VLAN Tags for different inner VLAN IDs
VLAN: the allowed VLAN, default VLAN and the link type (Trunk or Access) on
–
the interface, subnet VLAN configurations, protocol VLAN configurations, and
whether VLAN packets carry Tag
Port properties: whether the interface is added to the isolation group, interface rate,
–
duplex mode, and link Up/Down status
MAC address learning: whether MAC address learning is enabled and whether the
–
interface is configured with MAC address limit.
