The above configuration takes effect after the reboot of the device.
z
AN IRF port that is bound with multiple physical IRF ports is an aggregation IRF port, which
increases the bandwidth and reliability on the IRF port. If you specify multiple physical IRF ports
with the
port-list
argument, you can configure an aggregation IRF port. You can configure at most
two physical IRF ports as an aggregation IRF port for an Switch 4210G series switch, and you can
only aggregate physical IRF ports 1 and 2, and physical IRF ports 3 and 4.
z
The
irf-port-id
argument represents the IRF port number. The
port-list
argument represents the
physical IRF port number. For the correspondence of IRF ports, refer to Correspondence between
an IRF port and a physical IRF port .
z
When you insert a one-port interface module into the slot on the rear panel, if the interface module
is in slot 1, the port on it will be numbered 1; and if the interface module is in slot 2, the port on it
will be numbered 3.
Setting a Member ID for a Device
The member ID of a device defaults to 1. During the establishment of an IRF, when the devices that
form the IRF have duplicated member IDs, the member ID of the master is decided first, and then the
member IDs of slaves are decided one by one according to their distances to the master, that is, the
nearest slave gets the smallest available ID, and the nearer slave gets the smaller available ID, and so
forth; after the IRF is established, if the newly added device and another member have duplicated IDs,
the IRF system assigns the smallest available ID for the new member. You can also set the member
IDs according to network planning.
For a device that is already in an IRF, you can use commands in
Table 27-1 to modify the member ID
of the device, and this modification will be effective after the reboot of the device.
For a device that is not in an IRF, you are recommended to set its member ID in the following way:
1) Plan the member IDs in advance. You can view the member IDs of an IRF, and find out an unused
ID for the new device.
2) Log in to the device to be added into the IRF, and change its member ID to the unused ID found
out in step 1.
3) Save the current configuration. Power off the device, connect the device with IRF cables and
power it on. Use the configuration introduced in this section to enable IRF on the device and add it
into the IRF.
