NOTE
Read the information in this chapter thoroughly before you attempt to install or remove the BlackDiamond 10K
Series Management Switch Module (MSM).
Overview of MSMs
This overview describes the BlackDiamond 10K series MSMs, including:
●
MSM Activity
●
MSM LEDs
The MSM holds both the control plane and the switch fabric for the switch. One MSM is required for
switch operation; adding an additional MSM increases reliability and throughput.
Each MSM has two CPUs for protocol processing and network management. For full redundancy, you
can install up to two MSMs in the BlackDiamond 10K series switch.
The MSM-1 and MSM-1XL have different size Ternary Content Addressable Memory (TCAM). TCAM is
used for Longest Prefix Match routing lookups, learned MAC addresses, and access control lists (ACLs).
The MSM-1XL supports 256,000 entries in its lookup tables, while the MSM-1 supports 128,000 entries
in its lookup table. One of these entries is used per MAC learned, one per IP route, and two per ACL;
the lookup table space is dynamically allocated.
For example, if 20,000 ACLs are configured on an MSM-1, along with a routing table of 40,000 entries,
then 48,000 entries would remain for MAC learning. 128,000 total entries - 2 x (20,000 ACLs) - 1 x
(40,000 IP routes) = 48,000.
Table 13
shows that packet throughput between I/O modules increases when additional MSMs are
installed.
