Configuring a Switch

 

 

 

 

4.7.2.5

Broadcast Support

Broadcast is supported on the switch and allows for TCP/IP support. Broadcast is implemented using the proposed standard specified in Multi-Switch Broadcast for FC-SW-3, T11 Presentation Number T11/02-031v0. Fabric Shortest Path First (FSPF) is used to set up a fabric spanning tree used in transmission of broadcast frames. Broadcast frames are retransmitted on all ISLs indicated in the spanning tree and all online N_Ports and NL_Ports. Broadcast zoning is supported with Access Control List (ACL) hard zones. When a broadcast frame is received, these hard zones are enforced at the N_Ports and NL_Ports. If the originator of the broadcast is in a hard zone, the frame is retransmitted on all online N_Ports and NL_Ports within the hard zone. If the originator of the broadcast frame is not in a hard zone, the frame is retransmitted on online N_Ports and NL_Ports that are not in a hard zone. The default setting is disabled.

4.7.2.6

In-band Management

In-band management is the ability to manage switches across inter-switch links using SANsurfer Switch Manager, SNMP, management server, or the application programming interface. The switch comes from the factory with in-band management enabled. If you disable in-band management on a particular switch, you can no longer communicate with that switch by means other than a direct Ethernet or serial connection.

4.7.2.7

Interop Mode for Zoning

When a zone set is activated, FC-SW-2 compliant switches propagate the active zone set to all switches in the fabric. Some non-FC-SW-2 compliant switches propagate not only the active zone set, but the entire zoning database. Disabling the Interop Mode parameter causes the switch to propagate the zoning database, and therefore, interoperate with non-FC-SW-2 switches. For FC-SW-2 compliant fabrics, the Interop Mode parameter should be enabled.

Note: The Interop Mode setting must be the same on all switches in the

fabric, otherwise the inter-switch links will not connect.
