Figure 18: Multiple EAPS domains sharing a common link with EAPS shared ports
The switches on either end of the common link must be configured as controller and a partner . For
information about configuring common links, see “Configuring EAPS Shared Ports” on page 282 .
NOTE
If the shared port is not configured and the common link goes down a superloop between the multiple EAPS
domains will occur.
NOTE
In order to take advantage of the Spatial Reuse technology in a shared-port environment in this software release, you
can
use the existing solution of configuring EAPS plus STP.
Configuring EAPS on a Switch
To configure and enable an EAPS domain, complete the following steps:
1 Create EAPS domain and assign the name.
2 Configure the control VLAN.
3 Configure the protected VLAN(s).
4 Add the control VLAN to EAPS domain.
5 Add the protected VLAN(s) to EAPS domain.
6 Configure EAPS mode, master or transit.
7 Configure EAPS port, secondary and primary.
8 If desired, configure timeout and action for failtimer expiration*.
9 If desired, configure the hello time for the health-check packets*.
10 Enable EAPS for the entire switch.
