926 CHAPTER 84: SMART LINK CONFIGURATION
Configuring Associated
Devices
An associated device mentioned in this document refers to a device that supports
Smart Link and locally configured to process flush messages received from the
specified control VLAN so as to work with the corresponding Smart Link device. As
shown in Figure 257, all the devices including Switch C, Switch D, and Switch E on
the active and backup links connecting the Smart Link device (Switch A) and the
target uplink device (Switch E) are all associated devices.
However, you do not have to enable all the ports of an associated device to
process flush messages received from the specified control VLAN. You need to
enable this function only on the ports that are on the active and backup links
connecting the Smart Link device and the target device. As shown in Figure 257,
you need to enable this function on Ethernet 2/0/2 and Ethernet 2/0/3 of Switch
C, Ethernet 2/0/2 and Ethernet 2/0/3 of Switch D, and Ethernet 12/0/1 and
Ethernet 2/0/12 of Switch E.
