EAPS Shared Port Configuration Rules
The following rules apply to EAPS shared port configurations:
●
The controller and partner shared ports on either side of a common link must have the same
link ID.
●
Each common link in the network must have a unique link ID.
●
The modes on either side of a common link must be different from each other; one must be a
controller and one must be a partner .
●
There can be only up to two shared ports per switch.
●
There cannot be more than one controller on a switch.
Valid combinations on any one switch are:
●
1 controller
●
1 partner
●
1 controller and 1 partner
●
2 partners
●
A shared port cannot be configured on an EAPS master’s secondary port.
EAPS Shared Port Configuration Examples
This section provides examples of EAPS shared port configurations.
Basic Configuration
This example, shown in Figure 21 , is the most basic configuration; two EAPS domains with a single
common link between them.
