E-Ports
E ‐ ports (expansion ports) connect two full fabric switches to form an inter ‐ switch
link (ISL). Up to four Fibre Channel ISLs can be established between two full fabric
switches.
Only Fibre Channel port types can be configured as E ‐ ports. These ports must be
members of a Fibre Channel VLAN. Use the following commands to configure
E ‐ ports:
To verify the port configuration and operational state, use the following command:
In a stack of switches, ports on the Master or Backup switches can be configured as
E ‐ ports.
If different zones were configured on the switches being connected using E ‐ ports,
the zones merge to establish a consistent zoning policy across the fabric. The zones
on the two switches must belong to any one zoneset.
Note:
Zones are added in the merged zoneset only if the zoneset on the individual
switch was active.
The following table lists the zone merge rules:
E ‐ ports cannot be used to form stack LAG links.
