Access Gateway limitations

The limitations of Access Gateway are as follows:

• Limited to switch platforms and embedded switch platforms listed in “Supported hardware and

software” on page xiii.

• Maximum number of AGs that can be connected to an Edge switch is 30

• Maximum number of devices that can be connected to a Fabric OS switch through AG depends

on the maximum number of local devices supported by Fabric OS.

• AG does not support loop devices.

Upgrade and downgrade considerations for switches in AG mode

Downgrading to Fabric OS v6.1.0 or earlier is supported; however, you must first disable the switch

from AG mode. Note the following considerations when upgrading and downgrading from Fabric OS

v6.2.0 to Fabric OS v6.1.0 and earlier:

• Downgrades to v6.0.0 or earlier Fabric OS versions are not allowed if any F_Port trunk is

active.

• Trunking must be disabled before downgrading to Fabric OS v6.0.0 or earlier.

• When a switch is set in AG mode, if you downgrade to v6.0.0x, all preferred Failover

settings are lost.

The following table describes the scenarios for upgrading and downgrading Fabric OS versions.
