ISCOM2600G-HI (A) Series Configuration Guide
The new member ID takes effect after device restart.
The ISF uses the member ID to uniquely identify member devices. Configurations of
the ISF interface and member priority are related to the member ID, so modification
of the member ID may cause configurations to change or loss. Use the command
with caution.
3.6.5 Configuring member priority
The member priority is used in role election. A device with higher priority can be elected as
the master device with high probability.
Configure the member priority for the ISCOM2600G-HI series switch as below.

3.6.6 Configuring reservation time for ISF bridge MAC address
The bridge MAC address is the MAC address when a device communicates as a bridge. Some
Layer 2 protocols (such as LACP) use bridge MAC addresses to identify devices, so a bridge
device on the network must have a unique bridge MAC address. If there are multiple devices
with the same bridge MAC address on the network, the bridge MAC address will conflict
with each other and thus the network communication will fail.
An ISF communicates with the external network as a virtual device, so it should have a
unique bridge MAC address, called the ISF bridge MAC address. It usually uses the bridge
MAC address of the master device as the ISF bridge MAC address.
Conflict with the bridge MAC address causes communication failure, but switching of the
bridge MAC address causes service interruption. In this case, you should configure the
reservation time for the ISF bridge MAC address according to actual network conditions:

switch as below.

When the reservation time for the ISF bridge MAC address is configured to 10min, the
ISF bridge MAC address remains the same within 10min if the master device leaves the
ISF. If the master device fails to return to the ISF, the bridge MAC address of the newly
elected master device will be the ISF bridge MAC address. This configuration is suitable
when the master device leaves the ISF for a short time and then returns (for example, the
master device is restarted or a link is faulty temporarily), and can thus avoid service
interruption due to switching of the bridge MAC address.
When the reservation time for the ISF bridge MAC address is permanent, the ISF bridge
MAC address remains the same regardless of whether the master leaves the ISF.
When the ISF bridge MAC address is configured to unreserved, the bridge MAC address
of the newly elected master device will be the ISF bridge MAC address when the master
leaves the ISF.
