Disabling ACL Adjacency Sharing for System Image Downgrade

Fibre Channel ACL adjacency sharing is enabled by default on the switches with an active Generation 2
switching module as of Cisco MDS SAN-OS Release 3.0(3), and with an active Generation 3 module as
of MDS NX-OS Release 4.1(1). Fibre Channel ACL adjacency sharing improves the performance for
zoning and inter-VSAN routing (IVR) network address translation (NAT). To prevent disruptions when
downgrading the system image on your switch to a release prior to Cisco SAN-OS Release 3.0(3), enter
the following command in EXEC mode:
switch# system no acl-adjacency-sharing
To reenable Fibre Channel ACL adjacency sharing on your switch, enter the following command in
EXEC mode:
switch# system acl-adjacency-sharing

Displaying SFP Diagnostic Information

You can use the show interface transceiver command to display small form-factor pluggable (SFP)
diagnostic information for Generation 2 switching modules.
