Gateway links

Gateway link merges SAN

By default, switch ports initialize links using the Exchange Link Parameters (ELP) mode 1. However, 
gateways expect initialization with ELP mode 2, also referred to as ISL R_RDY mode. Therefore, to 
enable two switches to link through a gateway, the ports on both switches must be set for ELP 
mode 2. 

Any number of E_Ports in a fabric can be configured for gateway links, provided the following 
guidelines are followed:

•

All switches in the fabric are using the core PID format, as described in 

•

The switches connected to both sides of the gateway are included when determining switch 
count maximums.

•

Extended links (those created using the Extended Fabrics licensed feature) are not supported 
through gateway links. 

Configuring a link through a gateway

1. Connect to the switch at one end of the gateway and log in using an account assigned to the 

admin role.

2. Enter the portCfgIslMode command.

3. Repeat steps 1 through 2 for any additional ports that will be connected to the gateway. 

4. Repeat this procedure on the switch at the other end of the gateway.
