MSM64i Activity
The BlackDiamond 6800 series switch can run with a single MSM64i installed. When you install
additional MSM64i modules, one of the MSM64i modules operates as the master, and the others become
the slaves.
The master MSM64i is responsible for upper-layer protocol processing and system management
functions. For example, OSPF computation and SNMP functions are performed by the master MSM64i.
Packet handling is distributed among the CPUs of all installed MSM64i modules.
When you save the switch configuration, it is saved to all MSM64i modules. If you download a new
ExtremeWare image, the image is downloaded to all MSM64i modules.
Selection of the master MSM64i occurs automatically. The following scenarios describe the selection
process:
•
When the BlackDiamond 6800 series switch boots with one or more MSM64i modules already
installed, and an MSM64i module is installed in slot A, the MSM64i in slot A becomes the master.
•
When the BlackDiamond 6800 series switch boots with a single MSM64i (regardless of the slot
position), it is selected as the master.
If additional MSM64i modules are added to the switch after powered on, the added MSM64i
modules become the slaves. MSM64i modules that operate as slaves can be inserted and removed
without disrupting network services.
•
If you remove the master MSM64i while the BlackDiamond 6800 series switch is operating, the slave
MSM64i experiences a soft reset and then becomes the master MSM64i.
For example, if you have a BlackDiamond 6816 switch with a master MSM64i in slot A and slave
MSM64i modules in slots B through D, and you remove the master MSM64i from slot A, the slave in
slot B becomes the master.
MSM64i Memory
The MSM64i has two 144-pin SODIMM sockets and ships with two 128 MB SODRAM modules
installed, as shown in Figure 116.
NOTE
The MSM64i supports only SODIMMs supplied by Extreme Networks.
